Spring+Mybatis+SpringMVC+Atomikos多数据源共存+不同数据库事物一致性处理

网上找了一大堆的例子，没一个跑通的，都是copy转发，哎，整理得好辛苦。。做个笔记，方便正遇到此问题的猿们能够得到帮助。。。。废话不多说，贴代码。。。。。

项目结构说明：

1.dao层的admin、website包中包含的Mapper.xml文件分别操作不同的数据库

2.举例：192.168.1.1下有个mysql数据库叫 odao_admin

　　　　192.168.1.2下有个sqlserver数据库叫 odao_mobile

　　　　详情见下方的jdbc.properties文件

com.atomikos.icatch.console_log_level =INFO

注意：jta.properties 文件在你复制的时候可能有空格，记得删掉

7:log4j.properties:

### set log levels ###
log4j.rootLogger = Debug , C , D , E   

### console ###
log4j.appender.C = org.apache.log4j.ConsoleAppender
log4j.appender.C.Target = System.out

8. 控制层 UserInfoController.java :

package com.odao.controller.user;

import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import com.odao.entity.UserInfo;
import com.odao.service.website.UserService;

@Controller
@RequestMapping("/user/")
public class UserInfoController {

    @Autowired
    private UserService userService;  

    @RequestMapping("userInfoList.do")
    public ModelAndView getUserInfoList(HttpServletRequest request, HttpServletResponse response){
        ModelAndView modelAndView = new ModelAndView("user/userInfoList");
        List<UserInfo> userInfoList = userService.selectAll();
        List<UserInfo> userInfo = userService.selectUser();
        modelAndView.addObject("userName",userInfoList.get(0).getTest_id()+"===="+userInfo.get(0).getTest_name());
        return modelAndView;
    }

    @ResponseBody
    @RequestMapping("updateUserInfo.do")
    public ModelAndView updateUserInfo(HttpServletRequest request, HttpServletResponse response){
        ModelAndView modelAndView = new ModelAndView("user/userInfoList");
        UserInfo user = new UserInfo();
        user.setTest_id(1);
        user.setTest_name("嗯~有耐心看到这里的都帅");;
        userService.saveUser(user);
        return modelAndView;
    }
}

9.业务逻辑层：UserService.java:

package com.odao.service.website;

import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.odao.dao.admin.user.AdminUserInfoDao;
import com.odao.dao.website.user.WebSiteUserInfoDao;
import com.odao.entity.UserInfo;

@Service
public class UserService  {

    @Autowired
    private WebSiteUserInfoDao websiteUserInfoDao;

    @Autowired
    private AdminUserInfoDao adminUserInfoDao;

    public List<UserInfo> selectAll() {
        return websiteUserInfoDao.selectAll();
    }

    public List<UserInfo> selectUser() {
        return adminUserInfoDao.selectUser();
    }
    
    public void saveUser(UserInfo userInfo){
        websiteUserInfoDao.saveUser(userInfo);
　　　　 //测试操作不同数据库时，事物回滚的一致性(要么都成功，要么都失败)
　　　　 if(1==1){
            throw new NullPointerException();
        }
        adminUserInfoDao.saveUser(userInfo);
    }

}

整个项目大致就这样，entity跟dao就不贴了，你们看方法也能猜到，图片上的transaction-context.xml文件内容我给弄到了spring-mybatis.xml里面，就是一些关于分布式事物的
