需求，根据用户角色列表  查询用户列表信息

之前我们传入的参数是Array，一个数组的形式，现在我们传入的是一个List集合，其他条件没有变化。

/**

* 需求：传入指定的用户角色，用户角色有1-n,获取这些用户角色下的用户列表信息

* @param roleids

* @return

*/

public List getUserListByRoleid_List(List roleList);

select * from smbms_user where userRole in

#{roleList}

1 //传入List集合的方式

2 @Test3 public voidtestGetUserByForeach_List(){4 SqlSession sqlSession = null;5 List userList = new ArrayList();6 userList.add(2);7 userList.add(3);8 List userListShow=new ArrayList();9 try{10 sqlSession =MyBatisUtil.createSqlSession();11 userListShow = sqlSession.getMapper(UserMapper.class).getUserListByRoleid_List(userList);12

13 } catch(Exception e) {14 //TODO: handle exception

15 e.printStackTrace();16 }finally{17 MyBatisUtil.closeSqlSession(sqlSession);18 }19 for(User user: userListShow){20 logger.debug("testGetUserListAddressByUserId UserCode: " + user.getUserCode() + " and UserName: " + user.getUserName()+"and userRole:"+user.getUserRole());21 }22
