qa數(shù)據(jù)源的mybatis mapper接口 package com.xy.dao

1?package?com.xy.dao;2?3?import?com.xy.model.NameQa;4?5?/**6??*?Created?by?helloworld?on?2015/1/30.7??*/8?public?interface?NameQaMapper?{9?????int?insert(NameQa?nameQa); 10?}

dev數(shù)據(jù)源的mybatis mapper接口 package com.xy.devdao

1?package?com.xy.daodev;2?3?import?com.xy.model.NameDev;4?5?/**6??*?Created?by?helloworld?on?2015/1/30.7??*/8?public?interface?NameDevMapper?{9?????int?insert(NameDev?nameDev); 10?}

處理事務(wù)的service

controller代碼

1?package?com.xy.controller;2?3?import?com.xy.service.NameService;4?import?org.springframework.beans.factory.annotation.Autowired;5?import?org.springframework.stereotype.Controller;6?import?org.springframework.ui.ModelMap;7?import?org.springframework.web.bind.annotation.RequestMapping;8?import?org.springframework.web.bind.annotation.RequestMethod;9?import?org.springframework.web.bind.annotation.RequestParam; 10? 11?/** 12??*?Created?by?helloworld?on?2014/11/22. 13??*/ 14?@Controller 15?public?class?mybatisController?{ 16? 17?????@Autowired 18?????NameService?nameService; 19? 20?????@RequestMapping(value?=?"/addName",?method?=?RequestMethod.POST) 21?????ModelMap?addName(@RequestParam("hasException")?boolean?hasException)?{ 22?????????try?{ 23?????????????nameService.addQaAndDev(hasException); 24?????????}?catch?(Exception?e)?{ 25?????????????e.printStackTrace(); 26?????????????return?new?ModelMap("false"); 27?????????} 28?????????return?new?ModelMap("true"); 29?????} 30? 31? 32?}

將項目打成war包，命名為mybatis.war部署在tomcat上。

測試：

request parameters: hasException=false

返回：true 數(shù)據(jù)添加成功

request parameters: hasException=true

返回：false 兩個數(shù)據(jù)庫數(shù)據(jù)都未添加
