构建转换工具(属性对照关系)

@Mapper(componentModel = "spring") // 支持spring
public interface KsxxConverter {

    KsxxConverter INSTANCE = Mappers.getMapper(KsxxConverter.class);

    @Mappings({
//            @Mapping(source = "id", target = "departmentId" ),
            @Mapping(target = "departmentId" ,expression = "java(Long.parseLong(DaoHelper.getSeq()))"),// 根据表达式代码生成目标对象ID
            @Mapping(source = "ksmc", target = "departmentName"),
            @Mapping(source = "ksjj",target = "departmentDesc"),
            @Mapping(source = "cjsj", target = "insertDt"),
//            @Mapping(source = "sjks", target = ""),
//            @Mapping(source = "pym", target = ""),
            @Mapping(source = "gxsj", target = "updateDt"),
            @Mapping(target = "hospitalId" ,expression = "java(21122415521000366L)"),
            @Mapping(target = "isVirtual" ,expression = "java(1)"),
    })
    Department toDepartment(Ksxx ksxx);  // 对象转换

    List<Department> toDepartmentList(List<Ksxx> ksxxes);  // 列表转换

}

调用转换工具

 @Test
    void testKsxxDao(){
        List<Ksxx> ksxxes = ksxxDao.queryAll(null);
        ksxxes.forEach(System.out::println);
        System.out.println("=======================================");
        List<Department> departments = KsxxConverter.INSTANCE.toDepartmentList(ksxxes);
        departments.forEach(System.out::println);
    }
