mybatis 关联查询 含有集合的嵌套查询 并传多个参数

前提：

三个表：公司，部门，员工   。(部门和员工表中 均有 companyId,departmentId 两字段)

要求：

查询部门信息和本部门中所有员工的信息， 

java实体类：

public class Department {
	/** 部门id */
	private int departmentId;
	/** 部门名 */
	private String departmentName;
	/** 部门经理 */
	private String departmentManagerName;
	/** 部门所属公司ID */
	private int companyId;
	/** 关联属性 ，用于封装部门对应的员工信息 */
	private List employees;

DAO:

public interface DepartmentDao {
	/**
	 * 根据公司ID、部门ID 查询部门信息 和 本部门所有员工信息
	 * @param comId
	 * @param deptId
	 * @return Department类
	 */
	public Department findDeptInfo(@Param("companyId") int comId,@Param("departmentId") int deptId);

mapper.xml:

departmentId,departmentName,departmentManagerName,companyId
employeeId,employeeName,sex,age,address,phoneNumber,companyId,departmentId,job

 
	select  from department where companyId=#{companyId} and departmentId=#{departmentId}; 



	
	



	select  from employee
	 where companyId=#{companyId} and departmentId=#{departmentId}; 

Test类：

public class TestFindDeptInfo {
	static AbstractApplicationContext ac;
	SqlSessionFactory factory;
	SqlSession session;
	DepartmentDao deptDao;
	
	@Before
	public void init(){
		String conf = "applicationContext.xml";
		ac = new ClassPathXmlApplicationContext(conf);
		factory = ac.getBean("ssf",SqlSessionFactory.class );
		session = factory.openSession();
	}
	@Test	
	public void testDao1(){
		deptDao = session.getMapper(DepartmentDao.class);
		Department dept = deptDao.findDeptInfo(6201, 1);
		System.out.println(dept);
	}
}

以上为基本思路，不提供详细代码。代码运行成功。
