16.2.30 (Realize the function of withdrawing from the team by inviting people into the team)

1. After a few days, I wrote a small project and wrote it down for my future self.

The first is a screenshot of the project

 and then the database table that needs to be used, only part of the data of the table is used

 

 2. The following is the implementation of the code (the order of reverse engineering)

(1) ibatis_team_quit.xml (the configuration of sqlmaqconfig.xml is not much to say)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap>

	<cacheModel id="teamIntegral" type="memory" readOnly="true"
		serialize="false">
		<flushInterval hours="24" />
	</cacheModel>
	
	<update id="updateTeamUserState" >
		<![CDATA[
			UPDATE
				t_team_user
			SET
				visit_state=9
			WHERE	
				user_id	=
				(SELECT
					user_id
				FROM
					t_user_info
				WHERE
					openfire_username=#openfire_username#)
			AND
				team_id = #team_id#
		]]>
	</update>
</sqlMap>

 （2）TeamQuitDao.java

package com.enjoy.golf.dao;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.stereotype.Repository;

@Repository
public class TeamQuitDao extends BaseDao{
	public int quitTeam(String openfire_username,int team_id){
			Map<String,Object> map = new HashMap<String, Object>();
			map.put("openfire_username", openfire_username);
			map.put("team_id", team_id);
			return this.getSqlMapClientTemplate().update("updateTeamUserState",map);
		}
	}

 （3）TeamQuitService.java

package com.enjoy.golf.service;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.enjoy.golf.dao.TeamQuitDao;

@Service
public class TeamQuitService {
	@Resource
	TeamQuitDao teamquitDao;
	
	@Transactional(readOnly = false)
	//Update the player's exit status
	public BaseResponse quitTeam(String openfire_username,int team_id){
		return teamquitDao.quitTeam(openfire_username, team_id) == 1?
				new BaseResponse("0", "Successfully exited"):
				new BaseResponse("1","Unsuccessful exit");
		
//		int flg=  teamquitDao.quitTeam(openfire_username, team_id)
//		if(flg == 1){
// return new BaseResponse("0", "Exited successfully");
//		}
// return new BaseResponse("1","Exit failed");
	}
}

	public @ResponseBody BaseResponse quitTeam(
			@RequestParam(defaultValue = "")String openfire_username,

				return teamquitService.quitTeam(openfire_username, team_id);
			}

}
