我的员工管理界面中，员工和小组属于多对一关系，小组和到部门属于多对一关系，这几张表关联在一块。

这里不再叙述删除和修改和查询，这两个功能和前面会员账号管理中的功能重复，不再记录。

新增：

这里面的部门，由于雇员表的外键关联小组表，所以这里需要将Team持久层的信息显示出来

public List<Team> insert() {
    		// TODO Auto-generated method stub
    		Session s=sessionFactory.openSession();
    		List<Team> list=s.createQuery("from Team").list();
    		return list;
    	}

但是添加到Emp表中是外键，所以里面value设置成team的主键。

添加功能核心代码：

持久层

public Emp(int id, String name, Team team) {
    	super();
    	this.id = id;
    	this.name = name;
    	this.team = team;
    }

业务层：

public void insert2(int id, String name, Team tid) {
    		// TODO Auto-generated method stub
    		 Session s=sessionFactory.openSession();
    		 Transaction t=s.beginTransaction();
    		 Emp emp =new Emp(id, name, tid);
    		 s.save(emp);
    		 t.commit();
    	}

action：

public String ensureIn(){
    		System.out.println(emp.getId());
    		System.out.println(emp.getName());
    		System.out.println(team.getId()+"forgin***************************");
    
    		ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
    		 EmpInter emp1=(EmpInter) ac.getBean("empImp");
    		 emp1.insert2(emp.getId(), emp.getName(), team);
    		 System.out.println("*********");
    		return "ensureIn";
    	}

效果图：
