As shown in fig. 1, the method includes:

and S110, acquiring the object to be converted.

In this embodiment, the object to be converted refers to an incoming data transmission object. The type of the object to be converted can be selected or set in a user-defined manner according to requirements, and is not limited herein. For example, the type of the object to be converted may include, but is not limited to, a vo (value object) type, an entity type, a domain type, a query type, and other Java object types.

Specifically, the electronic device may retrieve the object to be converted from the configuration file or the preset path, which is not limited herein.

S120, converting the object to be converted based on a static conversion rule to obtain a target type object, and assigning the attribute value of the object to be converted to the target type object.

In the embodiment of the present invention, the static transformation rule refers to a preconfigured static transformation rule, and it should be noted that in the JAVA programming language, the static state refers to static keyword modification before a calling method or rule. Static conversion rules may implement object conversion through a reflection mechanism. The JAVA reflection mechanism refers to that in a running state, all attributes and methods of any class can be known; any method and property can be called for any object. In the embodiment, the object conversion is realized through a reflection mechanism, the types of the object conversion can be enriched, and the development workload can be saved.

It can be understood that the target type object refers to a data transmission object for conversion output, and the type of the target type object may be selected or set in a customized manner according to requirements, which is not limited herein. For example, the types of object type objects may include, but are not limited to, VO (value object) type, entity type, domain type, query type, and other Java object types. And in the process of object conversion, the attribute values of the objects to be converted can be assigned to the target type objects at the same time.

On the basis of the above embodiment, assigning the attribute value of the object to be converted to the target type object includes: and calling a get function and a set function, and assigning the attribute value of the object to be converted to the target type object through the get function and the set function.

The get function and the set function are a get method and a set method in the JAVA program respectively.

Specifically, a get function and a set function can be automatically called through a reflection mechanism, and an attribute value is stored/taken through the get function and the set function, so that the attribute value of the object to be converted is assigned to the target type object.

On the basis of the above embodiment, before assigning the attribute value of the object to be converted to the target type object, the method further includes: and initializing the target type object, and if the initialization fails, throwing an exception.

It is to be understood that the attribute values of the object to be converted may be assigned to the target type object only after the target type object has been initialized.

On the basis of the above embodiment, after the obtaining the object to be converted, the method further includes: and judging whether the incoming parameters are null or not, and if the incoming parameters are null, returning null characters.

Wherein the incoming parameters may include an object to be converted and a target type object.

Illustratively, the implementation process of assigning the attribute value of the object to be converted to the target type object is specifically as follows:

when the incoming parameter is null, directly returning to null;

when the incoming parameter is not null:

the target type object (i.e., output object) nxtObj is initialized, and if the initialization fails, an exception is thrown. According to the attribute of the input object to be converted, the same attribute of the output object nxtObj is assigned:

acquiring a get method corresponding to the preObj attribute, and assigning a value to a getMethod;

acquiring a corresponding value of a preObj attribute, assigning the value to a paraObject, and if an abnormal error report occurs, upwards throwing the abnormality, wherein the abnormal error report comprises java.

Acquiring the parameter type of a set method corresponding to the nxtObj attribute, and assigning the parameter type to setMethodParaClass;

acquiring a set method corresponding to the nxtObj attribute, and assigning the set method to a setMethod;

the corresponding attribute of nxtObj is assigned a value.

It should be noted that the static conversion rule of this embodiment is set by self-definition in advance, and is data that can be modified or added, so that the degree of freedom of object conversion is improved, and thus, conversion of multiple object types can be implemented as required.

On the basis of the above embodiment, the static conversion rule includes a domain type object conversion VO type object rule; correspondingly, based on the static conversion rule, converting the object to be converted to obtain the target type object, including: and converting the object to be converted in the domain type based on the VO type object conversion rule of the domain type object to obtain the target type object in the VO type.
