Model类如下：package com.xy.model

1 package com.xy.model;2 3 /**4  * Created by helloworld on 2015/1/30.5  */6 public class NameQa {7     private long id;8     private String nameQa;9
10     public long getId() {
11         return id;
12     }
13
14     public void setId(long id) {
15         this.id = id;
16     }
17
18     public String getNameQa() {
19         return nameQa;
20     }
21
22     public void setNameQa(String nameQa) {
23         this.nameQa = nameQa;
24     }
25 }

1 package com.xy.model;2 3 /**4  * Created by helloworld on 2015/1/30.5  */6 public class NameDev {7     private long id;8     private String nameDev;9
10     public long getId() {
11         return id;
12     }
13
14     public void setId(long id) {
15         this.id = id;
16     }
17
18     public String getNameDev() {
19         return nameDev;
20     }
21
22     public void setNameDev(String nameDev) {
23         this.nameDev = nameDev;
24     }
25 }

qa数据源的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数据源的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 }

处理事务的service

1 package com.xy.service;2 3 import com.xy.dao.NameQaMapper;4 import com.xy.daodev.NameDevMapper;5 import com.xy.model.NameDev;6 import com.xy.model.NameQa;7 import org.springframework.beans.factory.annotation.Autowired;8 import org.springframework.stereotype.Service;9 import org.springframework.transaction.annotation.Transactional;10
11 /**
12  * Created by helloworld on 2015/1/30.
13  */
14 @Service
15 public class NameService {
16     @Autowired
17     NameQaMapper nameQaMapper;
18     @Autowired
19     NameDevMapper nameDevMapper;
20
21     @Transactional(rollbackFor = Exception.class)
22     public void addQaAndDev(boolean hasException) throws Exception {
23         NameQa nameQa = new NameQa();
24         nameQa.setNameQa("qa");
25         nameQaMapper.insert(nameQa);
26
27         NameDev nameDev = new NameDev();
28         nameDev.setNameDev("dev");
29         nameDevMapper.insert(nameDev);
30
31         if(hasException) {
32             throw new Exception();
33         }
34     }
35
36
37 }

controller代码

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 }

将项目打成war包，命名为mybatis.war部署在tomcat上。

测试：

request parameters: hasException=false

返回：true 数据添加成功

request parameters: hasException=true

返回：false 两个数据库数据都未添加
