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

 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"> 3     <modelVersion>4.0.0</modelVersion> 4     <groupId>SpringMybatis</groupId> 5     <artifactId>SpringMybatis</artifactId> 6     <packaging>war</packaging> 7     <version>0.0.1-SNAPSHOT</version> 8     <name>SpringMybatis Maven Webapp</name> 9     <url>http://maven.apache.org</url>10     <dependencies>11         <dependency>12             <groupId>org.springframework</groupId>13             <artifactId>spring-core</artifactId>14             <version>3.2.10.RELEASE</version>15         </dependency>16         <dependency>17             <groupId>org.springframework</groupId>18             <artifactId>spring-web</artifactId>19             <version>3.2.10.RELEASE</version>20         </dependency>21         <dependency>22             <groupId>org.springframework</groupId>23             <artifactId>spring-webmvc</artifactId>24             <version>3.2.10.RELEASE</version>25         </dependency>26         <dependency>27             <groupId>org.mybatis</groupId>28             <artifactId>mybatis</artifactId>29             <version>3.2.8</version>30         </dependency>31         <dependency>32             <groupId>org.mybatis</groupId>33             <artifactId>mybatis-spring</artifactId>34             <version>1.1.1</version>35         </dependency>36         <dependency>37             <groupId>mysql</groupId>38             <artifactId>mysql-connector-java</artifactId>39             <version>5.0.2</version>40         </dependency>41         <dependency>42             <groupId>junit</groupId>43             <artifactId>junit</artifactId>44             <version>4.12</version>45             <scope>test</scope>46         </dependency>47         <dependency>48             <groupId>com.alibaba</groupId>49             <artifactId>druid</artifactId>50             <version>1.0.11</version>51         </dependency>52         <dependency>53             <groupId>log4j</groupId>54             <artifactId>log4j</artifactId>55             <version>1.2.17</version>56         </dependency>57     </dependencies>58     <build>59         <finalName>SpringMybatis</finalName>60     </build>61 </project>

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。

 

二、相关配置

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 @Controller11 @RequestMapping("/userController")12 public class UserController {13     14     private UserServiceI userService;15     16     public UserServiceI getUserService() {17         return userService;18     }19     @Autowired20     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);            }}

 

showuser.jsp

看下效果图：

 

好了，SpringMVC+Mybtis+Druid完美整合~
