　　DemoMysql2DaoMapper.xml

   <?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.xx.xxdp.dao.mysql.demo.DemoMysql2Dao">
<insert id="insert" parameterType="DemoMysql2" >
insert into demoMysql2  values (#{id}, #{name})
</insert>
<update id="update" parameterType="DemoMysql2" >
update demoMysql2
<set>

</mapper>
　　DemoMysql2Dao.java

package com.xx.xxdp.dao.mysql.demo;
import java.util.List;
import com.xx.xxdp.domain.mysql.demo.DemoMysql;
import org.apache.ibatis.annotations.Param;
import com.xx.xxdp.domain.mysql.demo.DemoMysql2;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

/**
* demo dao
*/
@Repository
public interface DemoMysql2Dao {
public int insert(DemoMysql2 demo);//注意方法名和Mapper中定义一致
public int delete(@Param("id") Integer id);
public int update(DemoMysql2 demo);
public DemoMysql2 get(@Param("id") Integer id);
public List<DemoMysql2> list();
//注解形式
@Select("select name,title from demoMysql2")
public List<DemoMysql2> getList();
}
　　service接口

package com.xx.xxdp.service.demo;
import org.springframework.transaction.annotation.Transactional;
import com.xx.xxdp.domain.hivemeta.demo.DemoHiveMeta;
import com.xx.xxdp.domain.mysql.demo.DemoMysql;
import java.util.List;

public interface DemoService {
/**
* 跨数据源的事务， DemoMysql和DemoHiveMeta位于不同的数据库
* @param demoMysql
* @param meta
*/
@Transactional
public void update(DemoMysql demoMysql, DemoHiveMeta meta);
//注解的形式
public List<DemoMysql> setList();
}
　　Impl调用实例

package com.xx.xxdp.service.demo.impl;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.xx.xxdp.dao.hivemeta.demo.DemoHiveMetaDao;
import com.xx.xxdp.dao.mysql.demo.DemoMysqlDao;
import com.xx.xxdp.domain.hivemeta.demo.DemoHiveMeta;
import com.xx.xxdp.domain.mysql.demo.DemoMysql;
import com.xx.xxdp.service.demo.DemoService;
import java.util.List;

/**
* demo服务实现类
* @author  
*/
@Service("demoService")
public class DemoServiceImpl implements DemoService {
private final static Logger LOG = Logger.getLogger(DemoServiceImpl.class);
@Autowired
private DemoMysqlDao demoMysqlDao;
@Autowired
private DemoHiveMetaDao demoHiveMetaDao;
public void update(DemoMysql demoMysql, DemoHiveMeta meta) {
demoMysqlDao.update(demoMysql);
if (  1 == 1 ) {
throw new RuntimeException();
}
demoHiveMetaDao.update(meta);
}
public List<DemoMysql> setList(){
return demoMysqlDao.getList();
}
}
　　接下来就是@Controller调用了

@Controller
public class SingleAnalysisControl {
private static final Logger log = Logger.getLogger(Control.class);
@Resource(name="demoService")
private demoServiceDemoService;

@RequestMapping(value = "/getList", method = RequestMethod.GET)
public ModelAndView getSingleAnalysis(HttpServletRequest httpServletRequest,@RequestParam(value = "sku", required = false, defaultValue = "") String sku,@RequestParam(value = "theDay", required = false, defaultValue = "") String theDay) {
ModelAndView view = new ModelAndView();
List<DemoMysql> listPro=null;
try {
if (theDay.isEmpty()) {
return null;
} else {
listPro = demoService.getList();
view.addObject("listViewsSourceDetail",listPro);
}
} catch (Exception ex) {
log.error(ex.getMessage());
}
return view;
}
}
