Idea SpringMVC+Spring+MyBatis+Maven整合File-New Project
选中左侧的Maven,选中右侧上方的Create from archetype,然后选中下方列表中的webapp,然后点击Next
在GroupId和ArtifactId中填入指定内容,点击Next
直接点Next
输入项目名称,Finish
Idea会自动开始下载所依赖的包,等待其完成。
项目刚建好的时候是没有这些文件的,所以自己手动创建缺少的文件夹(包)
创建完后的项目框架:
依赖包需要如下:
spring framework
aspectj事务
c3p0数据源
servlet/jsp api
junit4
mybatis
mybatis spring整合
mysql driver
jstl

插件需要用到mybatis的逆向工程
完整的pom.xml代码清单:
user表结构(首先在mysql库中创建名字叫ssm的database库,可以生成.sql文件将下面的代码复制进去,通过在这个库下导入sql文件建user表,或者直接在ssm库下的窗口里粘贴创建user表)
DROP TABLE IF EXISTS `user`; /*!40101 SET @saved_cs_client = @@character_set_client */; /*!40101 SET character_set_client = utf8 */; CREATE TABLE `user` ( `id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(32) NOT NULL COMMENT '用户名称', `birthday` date DEFAULT NULL COMMENT '生日', `sex` char(1) DEFAULT NULL COMMENT '性别', `address` varchar(256) DEFAULT NULL COMMENT '地址', PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=27 DEFAULT CHARSET=utf8;

如果没有出错的话,应该会自动生成mapper接口文件、xml文件、pojo文件。
在resources/config中创建db.properties,该文件用来描述mysql连接信息
jdbc.driver = com.mysql.jdbc.Driver jdbc.url = jdbc:mysql://127.0.0.1:3306/mybatis?characterEncoding=UTF-8 jdbc.username = root jdbc.password =
在resources/config/mybatis中创建SqlMapConfig.xml文件,该文件为Mybatis的配置文件,由于跟spring整合,所以一些基础配置文件都在spring中,在这里该文件中值需要写文件的框架

创建一个简单的service,只有一个查看所有用户列表的功能
UserService.java
package com.elin4it.ssm.service; import com.elin4it.ssm.pojo.User; import java.util.List; /** * Created by 烽 on 2015/7/11. */ public interface UserService { /** * 查找所有用户 * @return * @throws Exception */ List<User> findUser()throws Exception; }
实现类UserServiceImpl.java
package com.elin4it.ssm.service; import com.elin4it.ssm.mapper.UserMapper; import com.elin4it.ssm.pojo.User; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; /** * Created by 烽 on 2015/7/11. */ @Service public class UserServiceImpl implements UserService { //User接口 此处注入UserMapper时需要在UserMapper接口上添加<span style="font-family: Arial, Helvetica, sans-serif;">@Component进行依赖注入</span> @Autowired private UserMapper userMapper; public List<User> findUser() throws Exception { //调用mapper类中的selectByExample方法,如果传入类型为null,则表示无条件查找 List<User> users = userMapper.selectByExample(null); return users; } }
package com.elin4it.ssm.controller; import com.elin4it.ssm.pojo.User; import com.elin4it.ssm.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import java.util.List; /** * Created by 烽 on 2015/7/11. */ @Controller @RequestMapping("/user") public class UserController { //service类 @Autowired private UserService userService; /** * 查找所用用户控制器方法 * @return * @throws Exception */ @RequestMapping("/findUser") public ModelAndView findUser()throws Exception{ ModelAndView modelAndView = new ModelAndView(); //调用service方法得到用户列表 List<User> users = userService.findUser(); //将得到的用户列表内容添加到ModelAndView中 modelAndView.addObject("users",users); //设置响应的jsp视图 modelAndView.setViewName("findUser"); return modelAndView; } }
根据之前写的controller,返回的视图为findUser,所以在/WEB-INF/views中创建findUser.jsp文件,用来显示查询出来的结果
