2、环境搭建

2.1 spring配置文件applicationContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"

    bean>

    
    <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
        
        <property name="dataSource" ref="dataSource"/>
    bean>

    
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.ssm.dao"/>
    bean>
beans>

2.2 springmvc的配置文件springmvc.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd">
    
    <context:component-scan base-package="com.ssm.controller">
        
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    context:component-scan>
    
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    bean>
    
    <mvc:annotation-driven/>
beans>

3、实现步骤

3.1 创建实体类User并生成get\set方法

package com.ssm.entity;

public class User {
    private Integer id;
    private String name;
    private Integer age;

    //get\set方法....此处省略
}

3.2 dao层，在接口上加上@Repository注解

package com.ssm.dao;

import com.ssm.entity.User;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface UserDao {

    @Insert("insert into user(name,age) values(#{name},#{age})")
    public void insertUser(User user);

    @Select("select * from user")
    public List<User> queryAll();
}

3.3 Serivce层，创建接口UserService，在实现类上加上@Service(“userService”)注解

package com.ssm.service;

import com.ssm.dao.UserDao;
import com.ssm.entity.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service("userService")
public class UserServiceImpl implements UserService{
    @Autowired
    private UserDao userDao;
    public void insertUser(User user) {
        System.out.println("service插入数据");
        userDao.insertUser(user);
    }
    public List<User> queryAll() {
        System.out.println("service查询全部数据");
        return userDao.queryAll();
    }
}

3.4 Controller层

package com.ssm.controller;

import com.ssm.entity.User;
import com.ssm.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.List;

@Controller
@RequestMapping("/user")
public class UserController {
    @Autowired
    private UserService userService;

    @RequestMapping("/queryAll")
    public String queryAll(Model model){
        System.out.println("controller查询全部数据");
        List<User> users = userService.queryAll();
        for (User user:users) {
            System.out.println(user);
        }
        model.addAttribute("users",users);
        return "success";
    }
    @RequestMapping("/insert")
    public String insert(User user){
        System.out.println("controller插入数据");
        userService.insertUser(user);
        return "success";
    }
}

4、View视图层

index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java"%>
<html>
<body>
<a href="user/queryAll">查询全部数据a>
<br>
<form method="post" action="user/insert">
    姓名：<input type="text" name="name"><br>
    年龄：<input type="text" name="age"><br>
    <input type="submit" value="插入数据"><br>
form>
body>
html>

success.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ page isELIgnored="false" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
    <title>Titletitle>
head>
<body>
<h1>跳转成功h1>

<c:forEach items="${users}" var="user">
    ${user}<br>
c:forEach>

body>
html>
