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
