MyBatis_7_一些select方法(通过map查找、返回一个List,返回一个map)

一些接口方法：

实现的映射方法：

Test方法

public void test04() throws IOException{

    SqlSessionFactory sqlSessionFactory = getSqlSessionFactory();
    //1.获取到的SqlSession不会自动提交数据
    SqlSession openSession = sqlSessionFactory.openSession();

    try{
        EmployeeMapper mapper = openSession.getMapper(EmployeeMapper.class);
        //Employee employee = mapper.getEmpByIdAndLastName(1,"tom");
        
       /* Map<String,Object> map = new HashMap<>();
        map.put("id",1);
        map.put("lastName","Tom");
        Employee employee = mapper.getEmpByMap(map);
        System.out.println(employee);*/

       List<Employee> like = mapper.getEmpsByLastNameLike("%e%");
       for(Employee employee : like){
           System.out.println(employee);
       }

       /*Map<String,Object> map = mapper.getEmpByIdReturnMap(1);
       System.out.println(map);*/

       Map<Integer,Employee> map = mapper.getEmpByLastNameLikeRetuenMap("%r%");
        System.out.println(map);

    }finally {
        openSession.close();
    }
}
