Spring3 + Spring MVC+ Mybatis 3+Mysql 项目整合（注解及源码）

备注：

之前在Spring3 + Spring MVC+ Mybatis 3+Mysql 项目整合中写到的框架只是用于测试使用，隔了一段时间之后回头看看，发现有许多需要改进的地方，最近项目中刚好用到，再次补充下！

1.项目目录：

2.需要的jar包列表：

3.spring bean 配置文件applicationContext.xml

静态资源文件访问条件

8.控制器：

@Controller

@RequestMapping("/manager")

public class ManagerAction {

    private final static String className = ManagerAction.class.getName();

    /*可使用@Resource替代@Autowired 例如：@Resource(name = "managerServiceImpl")*/

    @Autowired

    private ManagerService managerService;

    @RequestMapping("/login")

    public String checkLogin(ModelAndView model) {

        ManagerInfo managerInfo=managerService.checkLogin("shupao");

        System.out.println(managerInfo.getManagerName());

        model.setViewName("index");

        LogUtil.businessInfo(className, "manager "+managerInfo.getManagerName()+"login success");

        return "index";

    }

}

service:

/*@Service(value = "managerService")*/

public interface ManagerService {

 public ManagerInfo checkLogin(String name);

}

serviceImpl:

/*@Repository(value = "managerServiceImpl")*/

@Service(value = "managerService")

public class ManagerServiceImpl implements ManagerService {

    @Resource(name = "managerMapper")

    private ManagerMapper managerMapper;

    public ManagerInfo checkLogin(String name) {

        // TODO Auto-generated method stub

        return managerMapper.checkLogin(name);

    }

}

mapper:

@Repository(value = "managerMapper")

@Transactional

public interface ManagerMapper{

    public ManagerInfo checkLogin(String name);

}

mapping:

<?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.sgl.mapper.ManagerMapper">

总结

知识只有在用的时候才能变得活起来！与上篇文章相比，本次程序搭建的过程更加细致，考虑的东西也更加全面。不过还有许多需要探索的地方，还得加油！
