使用MapStruct packagecn.juwatech.mapstruct;publicclassMain{publicstaticvoidmain(String[]args){UserEntityuserEntity=newUserEntity();userEntity.setId(1L);userEntity.setName("John Doe");userEntity.setEmail("john.doe@example.com");UserDTOuserDTO=UserMapper.INSTANCE.userEntityToUserDTO(userEntity);Syst...

这里我们创建一个UserMapper接口: packagecn.juwatech.example.mapper;importcn.juwatech.example.dto.UserDTO;importcn.juwatech.example.entity.UserEntity;importorg.mapstruct.Mapper;importorg.mapstruct.Mapping;@MapperpublicinterfaceUserMapper{@Mapping(source="username",target="name")UserEntitytoEntity(UserDTO...
Now I have one question how to map custom methods to a special target. For example I have following interface mapper: @MapperpublicinterfaceItemMapper{staticItemMapperINSTANCE=Mappers.getMapper(ItemMapper.class);@Mappings({ @Mapping(source = "number", target = "itemnumber"), @Mapping(source = ...
The best way to achieve that is to provide a custom mapping method. For example: @MapperpublicinterfaceBlogMapper{@Mapping(target = "userId", source = "user.id"),@Mapping(target = "commentedDate", source = "createdDate")BlogDtoentityToDto(finalComment entity);defaultTimestampmap(Instant ins...

1 - 用Mapper注解标注Mapper接口(也可以是抽象类) 2 - 可以调用其他的Mapper,来转换复杂类型的字段 3 - 可以指定一个Decorator类对Mapper实现做定制 4 - 常用的practice:声明一个静态的INSTANCE,便于调用方引用 5 - 同名的字段会自动映射,不同名的通过Mapping注解指定映射关系和映射方法 ...
