mybatis in DDD

App中的tech部分的设置属于标配

app
- main
  - tech
    - config // 加密，事业相关的configuration
    - plug // 加密等拦截器的具体实现
    - Application // SringBootApplication 启动
  - resource // matis 配置相关的yml，mapper，config等
- test
  - // 调薪
  - // 查询

domain
infrusture

domain部分，主要是雇员和薪水类, 记得ddd模式特色

+ app
    + main
        + tech
            + config // 加密，事业相关的configuration
            + plug // 加密等拦截器的具体实现
            + Application // SringBootApplication 启动
        + resource // matis 配置相关的yml，mapper，config等
    + test
        + // 调薪
        + // 查询

domain
- employee
  - model
    - EmployeeInfoEntity
  - reposity
    - IEmployeeRepository
      - insertEmployInfo插入雇员
      - queryEmployInfo查询雇员信息
  - service
    - IEmployeeService
      - insertEmployInfo插入雇员
      - queryEmployInfo查询雇员信息
    - EmployeeService // 引入 @Resource IEmployeeRepository employeeRepository
- salary
  - model
    - entity
      - EmployeeEntity //这里只需要和薪水挂钩的雇员级别和岗位tatle信息就够了
      - EmployeeSalaryAdjustEntity //需要和调薪相关的信息
    - valobj
      - EmployeePostVO // 雇员级别区间，比如T1到T8， code， des等
    - aggreate
      - AdjustSalaryApplyOrderAggregate // 罗列了雇员编号，调薪单号，雇员实体，雇员调薪实体，融合model中2个类
  - reposity
    - adjustSalary(AdjustSalaryApplyOrderAggregate adjustSalaryApplyOrderAggregate) // 调节薪水
  - service
    - ISalaryAdjustApplyService
      - execSalaryAdjust(AdjustSalaryApplyOrderAggregate adjustSalaryApplyOrderAggregate)
    - SalaryAdjustApplyService

            + entity
                + EmployeeEntity //这里只需要和薪水挂钩的雇员级别和岗位tatle信息就够了

                + execSalaryAdjust(AdjustSalaryApplyOrderAggregate adjustSalaryApplyOrderAggregate)
            + SalaryAdjustApplyService

功能实现在这里，导入domain模块

infrustruture
- dao
  - IEmployeeDAO
  - IEmployeesalaryAdustDAO
  - IEmployeesalaryDAO
- repository
  - //这里做了对数据库表的操作，事业相关的，比如更新岗位，更新薪酬，写入流水，查询雇员和薪酬
  - EmployeeRespsitory
  - SalaryAdustRepository
- po
  - // 这里几个类和数据库表是对应的，一表一类
  - EmployeePO //跟domain 里面的 EmployeeEntity相比，多了自增id，去掉了薪水相关
  - EmployeeSalaryAdjustPO
  - EmployeeSalaryPO

上面写完了后想domain里面的类干嘛用，

+ app
    + main
        + tech
            + config // 加密，事业相关的configuration
            + plug // 加密等拦截器的具体实现
            + Application // SringBootApplication 启动
        + resource // matis 配置相关的yml，mapper，config等

app
- test
  - domain
    - // 这里是直接ISalaryAdjustApplyService 对 .model下面的类操作，测试薪水调整和查询雇员
    - IEmployeeServiceTest
    - ISalaryAdjustApplyServiceTest
  - infrastructure
    - //这里是直接IEmployeeSalaryDAO 对 EmployeeSalaryPO操作，只需要用到infrastructure.dao和po下面的类
    - IEmployeeDAOTest
    - IEmployeeSalaryAdjustDAOTest
    - IEmployeeSalaryDAOTest
  - ApiTest

- domain
    + employee
        + model
            + EmployeeInfoEntity
        + reposity
            + IEmployeeRepository
                + insertEmployInfo插入雇员
                + queryEmployInfo查询雇员信息 
        + service
            + IEmployeeService
                + insertEmployInfo插入雇员
                + queryEmployInfo查询雇员信息
            + EmployeeService // 引入 `@Resource IEmployeeRepository employeeRepository`

 

    + salary
        + model
            + entity
                + EmployeeEntity //这里只需要和薪水挂钩的雇员级别和岗位tatle信息就够了
                + EmployeeSalaryAdjustEntity //需要和调薪相关的信息
            + valobj
                + EmployeePostVO // 雇员级别区间，比如T1到T8， code， des等
            + aggreate
                +  AdjustSalaryApplyOrderAggregate // 罗列了雇员编号，调薪单号，雇员实体，雇员调薪实体，融合model中2个类
        + reposity
            + adjustSalary(AdjustSalaryApplyOrderAggregate adjustSalaryApplyOrderAggregate) // 调节薪水
        + service
            + ISalaryAdjustApplyService 
                + execSalaryAdjust(AdjustSalaryApplyOrderAggregate adjustSalaryApplyOrderAggregate)
            + SalaryAdjustApplyService

+ infrustruture

    + dao
        + IEmployeeDAO
        + IEmployeesalaryAdustDAO
        + IEmployeesalaryDAO

. + repository + //这里做了对数据库表的操作，事业相关的，比如更新岗位，更新薪酬，写入流水，查询雇员和薪酬 + EmployeeRespsitory

这里实现了两个方法，就是domain中IEmployeeRepository的插入和查询雇员的两个方法employeeInfoEntity这个enployeePO来源就是domain里面的employeeInfoEntity，就是domain里面的IEmployeeRepository的实现在这里

        ```java
        ry {
                EmployeePO employeePO = EmployeePO.builder()
                        .employeeNumber(employeeInfoEntity.getEmployeeNumber())
                        .employeeName(employeeInfoEntity.getEmployeeName())
                        .employeeLevel(employeeInfoEntity.getEmployeeLevel())
                        .employeeTitle(employeeInfoEntity.getEmployeeTitle())
                        .build();

                employeeDAO.insert(employeePO);

        ```
    + SalaryAdustRepository

    + po
        + // 这里几个类和数据库表是对应的，一表一类
        + EmployeePO //跟domain 里面的 EmployeeEntity相比，多了自增id，去掉了薪水相关
        + EmployeeSalaryAdjustPO 
        + EmployeeSalaryPO
