2.web.xml文件配置前端控制器，过滤器（处理中文乱码）和监听器（监听项目启动）

       
      
       Archetype Created Web Application
        
        
          
       
        org.springframework.web.context.ContextLoaderListener
         
        
        
          
       
        contextConfigLocation
           
       
        classpath:applicationContext.xml
         
        
        
          
       
        encodingFilter
           
       
        org.springframework.web.filter.CharacterEncodingFilter
           
             
        
         encoding
              
        
         UTF-8
            
           
             
        
         forceEncoding
              
        
         true
            
         
        
          
       
        encodingFilter
           
       
        /*
         
        
        
          
       
        SpringMVC
           
       
        org.springframework.web.servlet.DispatcherServlet
           
             
        
         contextConfigLocation
              
        
         classpath:springmvc.xml
            
           
           
       
        1
         
        
          
       
        SpringMVC
           
       
        /
         
      
     

 

3.创建springmvc.xml文件，进行spring与springmvc的整合配置

 

4.创建applicationContext.xml文件，进行spring与mybatis的整合配置

 

5.创建与数据库表对应的实体类，实体类属性与表中对应

package com.ssm.entity;public class User {    private int id;    private String username;    private String password;    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }    @Override    public String toString() {        return "User{" +                "id=" + id +                ", username='" + username + '\'' +                ", password='" + password + '\'' +                '}';    }}

 

6.创建dao层接口

package com.ssm.dao;import com.ssm.entity.User;import org.springframework.stereotype.Repository;import java.util.List;@Repositorypublic interface UserDao {    //查询所有用户信息    public List
     
       findAll();    //保存用户信息    public void save(User user);}
     

 

7.创建dao层的xml文件，用于写sql语句，文件路径与dao接口的路径对应，文件名与dao接口名一样

     
         
          
              select * from user        
          
      
               insert into user(username,password) values(#{username},#{password})    
      
     

 

8.创建service层，创建service层的接口

package com.ssm.service;import com.ssm.entity.User;import org.springframework.stereotype.Service;import java.util.List;@Servicepublic interface UserService {    //查询所有用户信息    public List
     
       findAll();    //保存用户信息    public void save(User user);}
     

 

9.创建service层的实现类

package com.ssm.service.Impl;import com.ssm.dao.UserDao;import com.ssm.entity.User;import com.ssm.service.UserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import java.util.List;@Servicepublic class UserServiceImpl implements UserService {    @Autowired    private UserDao userDao;    @Override    public List
     
       findAll() {        System.out.println("业务层：查询所有用户信息");        return userDao.findAll();    }    @Override    public void save(User user) {        System.out.println("业务层：添加用户信息");        userDao.save(user);    }}
     

 

10.创建controller层，创建类

package com.ssm.controller;import com.ssm.entity.User;import com.ssm.service.Impl.UserServiceImpl;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;@Controller@RequestMapping("/UserController")public class UserController {    @Autowired    private UserServiceImpl userService;    @RequestMapping("/findAll")    public ModelAndView findAll(){        ModelAndView modelAndView=new ModelAndView();        List
     
       list=userService.findAll();        modelAndView.addObject("list",list);        for(User u:list){            System.out.println(u);        }        modelAndView.setViewName("list");        System.out.println("controllrt中的findAll方法");        return modelAndView;    }    @RequestMapping("/save")    public String save(User user){        userService.save(user);        return "list";    }}
     

 

11.编写index.jsp页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>    跳转
     
    
          
          
      
     

 

12.编写list.jsp页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %><%@page isELIgnored="false" %>    ${list}
