基于Maven构建整合SpringMVC+Mybtis+Druid 使用Mybatis-Generator自动生成Dao、Model、Mapping相关文件

前几天趁空闲时间整合了下SpringMVC+Mybatis+Druid，这里小记录下，这个Demo是基于Maven构建的，数据源用的是阿里巴巴温少的开源项目Druid，数据库用的是Mysql。

由于Eclipse去安装Maven很不方便，也老出错，这里我使用的是Spring Tool Suite（STS，基于 Spring IDE ，提供了其它的一些特性，如基于 Spring dm Server 的osgi 开发，及其它一些 Spring 项目的支持，如 Spring Roo ， Spring Batch 等）。

这里是STS的下载地址（集成了Maven）：http://spring.io/tools/sts/all

先看一下整体的项目结构：

一、相关JAR包

由于是基于Maven的项目，找起JAR包自然就方便了许多，我们只需要知道JAR的名字或者其中关键字就可以很轻松的把JAR包以及依赖JAR下载下来，需要多少下多少。

这里给出pom的配置文件。

pom.xml

 1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 2     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

由于Maven会把JAR包所依赖的JAR包也一起下载下来，这里我们就不需要逐个去写Spring的相关JAR包。

这里用到了阿里巴巴温少的开源项目Druid的数据源，所以额外的多引入了一个Druid的JAR包。

关于JAR的扩展，如果有需要别的可以到：http://search.maven.org/ 去查找，然后复制到这个配置文件即可，Maven会帮我们自动下载添加。

三、项目演示

关于model、dao以及mapping的生成方式，在之前的文章《使用Mybatis-Generator自动生成Dao、Model、Mapping相关文件》有提到，这里就不再给出。

UserController.java

package lcw.controller;
 2 
import lcw.model.User;
 lcw.service.UserServiceI;
 5 
 org.springframework.beans.factory.annotation.Autowired;
 org.springframework.stereotype.Controller;
 org.springframework.ui.Model;
 org.springframework.web.bind.annotation.RequestMapping;
@Controller
11 @RequestMapping("/userController")
public  UserController {
13     
private UserServiceI userService;
15     
public UserServiceI getUserService() {
return userService;
    }
19     @Autowired
20     void setUserService(UserServiceI userService) {
this.userService =22 23 
24     @RequestMapping("/showUser" String showUser(Model model){
26         User user=userService.getUserById(1);
27         model.addAttribute("user",user);
28         return "showuser";
29 31 }

UserServiceI.java

1  lcw.service;
2 
3 4 
5 interface UserServiceI {
6     
7     public User  getUserById(int id);
8 
9 }

UserService.java

 lcw.service;

 org.springframework.stereotype.Service;

 lcw.dao.UserMapper;
 lcw.model.User;

@Service("userService"class UserService implements UserServiceI {

     UserMapper userMapper;
    
     UserMapper getUserMapper() {
         userMapper;
    }

    @Autowired
     setUserMapper(UserMapper userMapper) {
        this.userMapper = userMapper;
    }




    @Override
    public User getUserById( id) {
         userMapper.selectByPrimaryKey(id);
        
    }

}

showuser.jsp
