基于Maven构建整合SpringMVC+Mybtis+Druid

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

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

 1 package lcw.controller;
 2 
 3 import lcw.model.User;
 4 import lcw.service.UserServiceI;
 5 
 6 import org.springframework.beans.factory.annotation.Autowired;
 7 import org.springframework.stereotype.Controller;
 8 import org.springframework.ui.Model;
 9 import org.springframework.web.bind.annotation.RequestMapping;
10 @Controller
11 @RequestMapping("/userController")
12 public class UserController {
13     
14     private UserServiceI userService;
15     
16     public UserServiceI getUserService() {
17         return userService;
18     }
19     @Autowired
20     public void setUserService(UserServiceI userService) {
21         this.userService = userService;
22     }
23 
24     @RequestMapping("/showUser")
25     public String showUser(Model model){
26         User user=userService.getUserById(1);
27         model.addAttribute("user", user);
28         return "showuser";
29     }
30 
31 }

 

UserServiceI.java

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

 

UserService.java

package lcw.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

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

@Service("userService")
public class UserService implements UserServiceI {

    private UserMapper userMapper;
    
    public UserMapper getUserMapper() {
        return userMapper;
    }

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




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

}
