In an object-oriented programming language such as Java, when the attribute structures (names and types) of a source object and a target object are completely consistent, a developer can simplify the attribute replication process by means of a reflection mechanism, a byte code enhancement technique (such as CGLib) or an object mapping framework (such as BeanUtils, dozer, mapStruct), and automatically or semi-automatically generate the target object. However, in a practical scenario, the service is more complex, and more scenarios are encountered, such as different types, need to query other dependency information, need to modify other fields, and the like, and complex conversion logic is generally scattered in a service code or a custom converter in a hard-coded form, which results in close coupling of the conversion logic and core service logic, so that maintainability of the code is reduced, and when the conversion rule changes, the conversion logic needs to go deep into the service code to modify, thereby increasing the risk of errors and the complexity of testing.
