具体实施方式Detailed ways
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
相关技术中，前端装置所下发的操作请求通常由多副本模式中的任一微服务装置处理，而该微服务装置则会将对应的处理状态信息保存至数据库，以便前端装置及时了解处理进度详情。请参考图1，图1为本申请实施例所提供的相关技术中微服务***更新处理进度值的示意图，可见，来自前端装置(操作界面)的操作请求由网关随机发送给微服务A、微服务B或微服务C进行处理，而这些微服务将对应的处理进度值写入数据库集群(Mariadb)，以便前端装置在数据库集群中进行查询。但在实际应用中，各微服务装置可能出现宕机情况，此时数据库中的处理状态信息将无法被改变，进而导致用户无法了解操作请求的处理情况以及微服务的运行状态，而这容易为用户带来不好的使用体验。In the related art, the operation request issued by the front-end device is usually processed by any micro-service device in the multi-copy mode, and the micro-service device will save the corresponding processing status information to the database, so that the front-end device can keep abreast of the processing progress details. Please refer to FIG. 1. FIG. 1 is a schematic diagram of the update processing progress value of the microservice system in the related art provided by the embodiment of the present application. It can be seen that the operation request from the front-end device (operation interface) is randomly sent by the gateway to the microservice A, microservice Service B or microservice C performs processing, and these microservices write the corresponding processing progress value into the database cluster (Mariadb), so that the front-end device can query in the database cluster. However, in practical applications, each microservice device may be down. At this time, the processing status information in the database will not be changed, and the user will not be able to understand the processing status of the operation request and the running status of the microservice. The user brings a bad experience.
有鉴于此，本申请提供一种信息更新方法，可设置目标微服务装置对自身运行状态进行检测，并在即将退出时向其他微服务装置提供标记信息，以便其他微服务装置依照标记信息更新目标微服务装置在数据库中的处理状态信息，进而解决用户无法了解操作请求的处理情况以及微服务运行状态的问题。In view of this, this application provides an information update method, which can set the target micro-service device to detect its own running status, and provide tag information to other micro-service devices when it is about to exit, so that other micro-service devices can update the target according to the tag information The processing status information of the micro-service device in the database can further solve the problem that the user cannot understand the processing status of the operation request and the running status of the micro-service.
参考图2，图2为本申请实施例所提供的一种信息更新方法的流程图，该方法应用于微服 务***，微服务***包括微服务装置，微服务装置至少包括第一微服务装置和第二微服务装置。需要说明的是，微服务装置的数量可大于2，可根据实际应用需求进行设定；此外，本申请实施例并不限定微服务***中可包含的其他装置，可以参考后文中的描述，也可根据实际应用需求进行设定。该方法可以包括：Referring to FIG. 2, FIG. 2 is a flow chart of an information update method provided by an embodiment of the present application. The method is applied to a microservice system. The microservice system includes a microservice device, and the microservice device includes at least a first microservice device and a Second microservice installation. It should be noted that the number of micro-service devices can be greater than 2, which can be set according to actual application requirements; in addition, the embodiment of the present application does not limit other devices that can be included in the micro-service system, you can refer to the description below, or It can be set according to actual application requirements. The method can include:
S101、第一微服务装置在处理前端装置发送的操作请求时，将对应的处理状态信息及第一微服务装置所在宿主机的宿主机名称保存至数据库。S101. When processing the operation request sent by the front-end device, the first micro-service device saves the corresponding processing status information and the name of the host machine where the first micro-service device is located in the database.
微服务装置部署在宿主机中，宿主机即为运行微服务的物理设备。本申请实施例并不限定宿主机是实体的电子设备，还是虚拟机，可根据实际应用需求进行设定，其中虚拟机指通过软件模拟的具有完整硬件***功能的、运行在一个完全隔离环境中的完整计算机***。需要指出的是，微服务装置与宿主机的对应关系为一对一。也正是如此，本申请实施例可根据宿主机的名称唯一确定一个微服务装置，而第一微服务装置同时将处理状态信息及所在宿主机的宿主机名称保存至数据库，也正是为了便于其他微服务装置根据该名称定位第一微服务装置。The microservice device is deployed in the host machine, and the host machine is the physical device running the microservice. The embodiment of the present application does not limit whether the host machine is a physical electronic device or a virtual machine, which can be set according to actual application requirements, wherein a virtual machine refers to a software simulation with complete hardware system functions, running in a completely isolated environment complete computer system. It should be pointed out that the corresponding relationship between the microservice device and the host machine is one-to-one. This is also the case, the embodiment of the present application can uniquely determine a micro-service device according to the name of the host machine, and the first micro-service device simultaneously saves the processing status information and the host machine name of the host machine where it is located to the database, precisely for the convenience of Other microservice devices locate the first microservice device according to the name.
进一步，需要说明的是，本申请实施例并不限定微服务装置具体需要处理的操作请求，可根据实际应用需求进行设定；本申请也不限定具体的数据库，以及处理状态信息和宿主机名称在该数据库中的存储形式，同样可根据实际应用需求进行设定。Further, it should be noted that the embodiment of this application does not limit the specific operation requests that need to be processed by the microservice device, which can be set according to actual application requirements; this application also does not limit the specific database, and the processing status information and host machine name The storage form in the database can also be set according to actual application requirements.
S102、第一微服务装置实时检测自身的运行状态，并在确定运行状态为即将关闭时，创建名称为宿主机名称的标志文件并保存至宿主机。S102. The first micro-service device detects its running state in real time, and when it is determined that the running state is about to be shut down, creates a flag file named as the name of the host machine and saves it to the host machine.
为及时向外界告知自身运行状态，本申请实施例中的第一微服务装置会自动检测自身运行状态，以确定自身是否即将发生关闭情况。若确定即将关闭，第一微服务装置则会进一步在宿主机中生成一个标志文件并命名为宿主机名称。显然，由于微服务装置与宿主机的关系为一对一，因此其他微服务装置可根据标志文件的名称确定第一微服务装置已关闭，进而便实现了第一微服务装置主动向外界告知自身运行状态的效果。In order to inform the outside world of its own running status in a timely manner, the first microservice device in the embodiment of the present application will automatically detect its own running status to determine whether it is about to shut down. If it is determined that it is about to be closed, the first micro-service device will further generate a flag file in the host machine and name it as the name of the host machine. Obviously, since the relationship between the micro-service device and the host is one-to-one, other micro-service devices can determine that the first micro-service device is closed according to the name of the flag file, and then realize that the first micro-service device actively notifies itself to the outside world The effect of the running state.
需要说明的是，本申请实施例并不限定检测微服务运行状态的具体方式，可参考微服务的相关技术。为提升检测效率，可在第一微服务装置中设置一个钩子程序(Hook)，专用于检测第一微服务装置的运行状态，并在确定该装置即将关闭时，执行创建标志文件的步骤。需要说明的是，本申请实施例并不限定钩子程序的实现方式，可参考钩子程序的相关技术。It should be noted that the embodiment of the present application does not limit the specific manner of detecting the running state of the microservice, and reference may be made to related technologies of the microservice. In order to improve the detection efficiency, a hook program (Hook) can be set in the first microservice device, which is specially used to detect the running state of the first microservice device, and when it is determined that the device is about to be shut down, execute the step of creating a flag file. It should be noted that the embodiment of the present application does not limit the implementation manner of the hook program, and reference may be made to related technologies of the hook program.
在一些实施例中，第一微服务装置中预设有钩子程序，第一微服务装置检测自身的运行状态，并在确定运行状态为即将关闭时，创建名称为宿主机名称的标志文件并保存至宿主机，可以包括：In some embodiments, a hook program is preset in the first microservice device, and the first microservice device detects its own running state, and when it is determined that the running state is about to close, it creates a flag file named as the name of the host machine and saves it. to the host machine, which can include:
步骤11：钩子程序检测第一微服务装置的运行状态，并在确定运行状态为即将关闭时，创建标志文件并保存至宿主机。Step 11: The hook program detects the running state of the first microservice device, and when it is determined that the running state is about to close, creates a flag file and saves it to the host machine.
本申请实施例并不限定标志文件的具体类型，只要该文件的名称为宿主机名称即可，其具体类型可根据实际应用需求进行设置。本申请也不限定标志文件在宿主机中的存放位置，只要该位置便于查找即可。The embodiment of the present application does not limit the specific type of the logo file, as long as the name of the file is the name of the host machine, and the specific type can be set according to actual application requirements. This application does not limit the storage location of the logo file in the host computer, as long as the location is easy to find.
S103、第二微服务装置在宿主机中查找标志文件，并在查找到标志文件时在数据库中将标志文件的名称对应的处理状态信息更新为处理失败。S103. The second microservice device searches the host machine for the logo file, and when the logo file is found, updates the processing status information corresponding to the name of the logo file in the database to processing failure.
在本申请实施例中，第二微服务装置用于帮助已关闭的微服务装置更新其在数据库中的处理状态信息。第二微服务装置会在各宿主机中查找标志文件，并根据该文件的名称在数据库中更新对应的处理状态信息。可以理解的是，已关闭的微服务装置将无法完成操作请求处理，因此第二微服务装置可将标志文件名称对应的处理状态信息更新为处理失败。当然，也可进一步标注处理失败的原因是微服务装置宕机，可根据实际应用需求进行设定。In the embodiment of the present application, the second microservice device is used to help the closed microservice device update its processing status information in the database. The second micro-service device will search for the flag file in each host machine, and update the corresponding processing status information in the database according to the name of the file. It can be understood that the closed micro-service device will not be able to complete the processing of the operation request, so the second micro-service device can update the processing status information corresponding to the flag file name as processing failure. Of course, it can also be further marked that the reason for the processing failure is that the microservice device is down, which can be set according to actual application requirements.
需要说明的是，本申请实施例并不限定第二微服务装置执行标志文件查找步骤的方式，例如可以实时执行，也可以周期性执行。为提升资源利用率，降低资源浪费，第二微服务装置可周期性在宿主机中查找标志文件。本申请实施例并不限定具体的周期数值，例如可以为30秒，也可以为其他数值，可根据实际应用需求进行设定。It should be noted that the embodiment of the present application does not limit the manner in which the second microservice device executes the logo file search step, for example, it may be executed in real time or periodically. In order to improve resource utilization and reduce waste of resources, the second microservice device may periodically search for the logo file in the host machine. The embodiment of the present application does not limit the specific period value, for example, it may be 30 seconds, or it may be other values, which can be set according to actual application requirements.
在一些实施例中，第二微服务装置在宿主机中查找标志文件，可以包括：In some embodiments, the second microservice device searches for the flag file in the host machine, which may include:
步骤21：第二微服务装置周期性在宿主机中查找标志文件。Step 21: The second microservice device periodically searches the host machine for the logo file.
进一步，为避免反复更新相同的处理状态信息，第二微服务装置在完成更新操作后，可将该标志文件进行删除。Further, in order to avoid repeatedly updating the same processing state information, the second microservice device may delete the flag file after completing the update operation.
在一些实施例中，在数据库中将标志文件的名称对应的处理状态信息更新为处理失败之后，还可以包括：In some embodiments, after the processing status information corresponding to the name of the flag file is updated as processing failure in the database, it may further include:
步骤31：第二微服务装置删除标志文件。Step 31: The second microservice device deletes the logo file.
进一步，虽然本申请实施例采用第一微服务装置和第二微服务装置进行介绍，但在实际应用中为保障微服务的服务质量，每一微服务装置均需要执行步骤S101和S102，例如微服务***中包含微服务装置A，微服务装置B和微服务装置C，则这三个微服务装置均需要执行步骤S101和S102；此外，为避免资源浪费，可指定一个特定的微服务装置执行步骤S103，例如在上述例子中，可指定微服务装置B执行步骤S103。Further, although the embodiment of this application uses the first microservice device and the second microservice device for introduction, in order to ensure the service quality of microservices in practical applications, each microservice device needs to perform steps S101 and S102, for example, the microservice The service system includes microservice device A, microservice device B and microservice device C, and these three microservice devices need to execute steps S101 and S102; in addition, in order to avoid waste of resources, a specific microservice device can be designated to execute In step S103, for example, in the above example, microservice device B may be designated to execute step S103.
基于上述实施例，本申请中的第一微服务装置在处理前端装置所发送的操作请求时，会将对应的处理状态信息和该微服务装置所在宿主机的宿主机名称同时保存在数据库中，以便 其他微服务装置在数据库中定位第一微服务装置所生成的所有处理状态信息；同时，第一微服务装置还会对自身的运行状态进行实时检测，并在确定自身处于即将关机的状态时，创建一个文件名为宿主机名称的标志文件，以便其他微服务装置进行查找；最后，本申请将设置另一个微服务装置即第二微服务装置在各宿主机中查找这一标志文件，当查找到该标志文件时，则说明该文件对应的微服务装置已宕机，此时便可在数据库中将该文件的名称对应的处理状态信息更新为处理失败，以便前端用户及时了解操作请求的处理情况，进而提升用户对微服务***的使用体验。Based on the above-mentioned embodiment, when the first microservice device in this application processes the operation request sent by the front-end device, it will simultaneously save the corresponding processing status information and the name of the host machine where the microservice device is located in the database, so that other microservice devices can locate all the processing status information generated by the first microservice device in the database; at the same time, the first microservice device will also perform real-time detection of its own running status, and when it is determined that it is in the state of being about to shut down , create a logo file with the name of the host computer so that other micro-service devices can search for it; finally, this application will set another micro-service device, the second micro-service device, to search for this logo file in each host machine, when When the flag file is found, it means that the microservice device corresponding to the file is down. At this time, the processing status information corresponding to the name of the file can be updated in the database as processing failure, so that the front-end user can know the status of the operation request in a timely manner. Handle the situation, and then improve the user experience of the microservice system.
基于上述实施例，为确保第二微服务装置可靠，也可单独设置集群调度装置，用于对第二微服务装置进行检测，并在确定第二微服务装置正常工作时，才控制其执行标志文件查找步骤。在一些实施例中，微服务***还可以包括集群调度装置，在第二微服务装置在宿主机中查找标志文件之前，还可以包括：Based on the above-mentioned embodiment, in order to ensure the reliability of the second microservice device, a cluster scheduling device can also be set separately to detect the second microservice device, and only control its execution flag when it is determined that the second microservice device is working normally File lookup steps. In some embodiments, the microservice system may also include a cluster scheduling device, and before the second microservice device searches for the flag file in the host computer, it may also include:
S201、集群调度装置检测第二微服务装置的第一工作状态。S201. The cluster scheduling device detects the first working state of the second microservice device.
需要说明的是，本申请实施例并不限定具体的集群调度装置，可参考微服务集群的相关技术。本申请同样不限定检测第二微服务装置工作状态的方式，可参考微服务的相关技术。It should be noted that the embodiment of the present application does not limit a specific cluster scheduling device, and reference may be made to related technologies of microservice clusters. The present application also does not limit the method of detecting the working state of the second microservice device, and reference may be made to related technologies of microservices.
S202、在确定第一工作状态为正常时，则控制第二微服务装置执行在宿主机中查找标志文件的步骤。S202. When it is determined that the first working state is normal, control the second microservice device to execute the step of searching the flag file in the host machine.
可以理解的是，集群调度装置仅在第二微服务装置正常工作时，才可控制其执行标志文件查找步骤。然而，第二微服务装置也可能发生异常宕机，此时集群调度装置可获取其他微服务装置的工作状态，并在确定其他微服务装置正常工作时，将标志文件查找任务由第二微服务装置转移至其他微服务装置。It can be understood that the cluster scheduling device can only control the second microservice device to execute the flag file search step when it is working normally. However, abnormal downtime may also occur in the second microservice device. At this time, the cluster scheduling device can obtain the working status of other microservice devices, and when it is determined that other microservice devices are working normally, the flag file search task will be assigned to the second microservice device. The device is transferred to other microservice devices.
在一些实施例中，在集群调度装置检测第二微服务装置的第一工作状态之后，还可以包括：In some embodiments, after the cluster scheduling device detects the first working state of the second microservice device, it may further include:
步骤41：集群调度装置在确定第一工作状态为异常时，则检测微服务***中的其他微服务装置的第二工作状态，并在确定第二工作状态为正常时，控制其他微服务装置执行在宿主机中查找标志文件的步骤。Step 41: When the cluster scheduling device determines that the first working state is abnormal, it detects the second working state of other microservice devices in the microservice system, and when it determines that the second working state is normal, controls other microservice devices to execute Steps to find flag files on the host machine.
需要说明的是，本申请实施例并不限定集群调度装置执行工作状态检测的方式，例如可以为实时监测，也可以为周期性检测，同样可根据实际应用需求进行设定。It should be noted that the embodiment of the present application does not limit the manner in which the cluster scheduling device detects the working status. For example, it may be real-time monitoring or periodic detection, which may also be set according to actual application requirements.
基于上述实施例，本***还可引入集群调度装置，用于对第二微服务装置进行检测，并在确定第二微服务装置正常工作时，才控制其执行标志文件查找步骤，进而可有效确保标志 文件查找任务能够被正确执行。Based on the above embodiments, the system can also introduce a cluster scheduling device to detect the second microservice device, and only control it to execute the flag file search step when it is determined that the second microservice device is working normally, thereby effectively ensuring Flag file lookup tasks are executed correctly.
下面基于流程图介绍上述信息更新方法进行介绍。参考图3，图3为本申请实施例所提供的微服务宕机处理流程的示意图，可见，微服务A在即将关闭之前，会调用钩子程序，在宿主主机的某个目录下面写入一个文件(Pod)，文件的名字就是宿主机名称(podName)。参考图4，图4为本申请实施例所提供的数据库更新处理流程的示意图，可见，执行标志文件查找的微服务会根据podName检索数据库表数据，然后修改文件处理的进度和状态。如果当前微服务不存在文件处理，也会写入podName，只是检索不出来数据而已。The above information update method will be described below based on the flow chart. Referring to Figure 3, Figure 3 is a schematic diagram of the microservice downtime processing flow provided by the embodiment of the present application. It can be seen that before the microservice A is about to be closed, it will call the hook program and write a file under a certain directory of the host computer (Pod), the name of the file is the host name (podName). Referring to FIG. 4, FIG. 4 is a schematic diagram of the database update processing flow provided by the embodiment of the present application.
