关于Spring + Spring MVC + MyBatis的搭建

1.在IDEA界面中创建MavenWeb工程选中下图maven-archetype-webapp

2.在pom.xml中添加如下相关依赖

3.web.xml 配置 Spring MVC、Spring 设置字符编码过滤器、加载静态资源。

4.分别在main目录下创建resource包并创建spring,springmvc,mybatis.xml文件

5.在spring.xml中连接数据库将user和password改成自己的数据库用户名和密码，并将3306/后面改成连接数据库的包名，紧接着配置SqlSessionFactory,扫描Mapper接口，事务管理等。

6.springmvc.xml中配置驱动和前后缀表达式

7.配置打印sql语句和指定实体类，让idea搜索需要的javaBean

8.创建与数据库相对应的实体类

9.Handler

package com.south.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import com.south.service.UserService; @Controller@RequestMapping("/user")public class UserHandler {@Autowiredprivate UserService userService; @GetMapping("/index")public ModelAndView index(){ModelAndView modelAndView=new ModelAndView(); modelAndView.setViewName("index"); modelAndView.addObject("list",userService.findAll()); return modelAndView; }}

10.Service及其接口

package com.south.service.impl; import com.south.entity.User; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.south.repository.UserRepository; import com.south.service.UserService; import java.util.List; @Servicepublic class UserServiceimpl implements UserService {@Autowiredprivate UserRepository userRepository; @Overridepublic List findAll() {return userRepository.findAll(); }}
