IDEA+MAVEN基于ssm框架的数据库的增删改查及登录

之前已经写过一种搭建ssm框架的方法，搭建时是直接在工程项目下创建java包结构和resources文件夹，这次将会用另外一种方法实现。
开发工具

IntelliJ IDEA 2018
Maven 3.6.0
JDK1.8
tomcat 7.0.79
Mysql 5.0

搭建ssm框架时，选择file->new->project->maven，右边的create from archetype 不要勾选，直接下一步，填写项目名，其他都和之前的项目搭建时步骤是一样的，具体可以参照上一篇博客：https://mp.csdn.net/postedit/94034286 ，其中不同的只是这次没有勾选create from archetype这个选项而已。
工程项目搭建完成后，在项目上右键，选择new->Module->Maven，同样不选择create from archetype，直接下一步，然后在ArtifactId上填写ssm_bean，完成，以此方法同样创建ssm_dao、ssm_service，而在创建ssm_web时，需要勾选create from archetype这一选项，选择maven-archetype-webapp，再依次执行操作即可，然后在每个Module下分别创建相关的包、接口和类，项目创建成功后目录结构为：
在这里插入图片描述

代码编写时跟上一篇所写的差不多，具体代码如下：
首先是配置文件，整个工程项目下的pom.xml文件：

同样是ssm_web->src->main->resources下，新建db.properties文件（注意数据库名和密码）：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/idea?useSSL=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456

在ssm_web->src->main->resources下，新建log4j.properties文件：

# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

在ssm_web->src->main->resources下，新建spring-mvc.xml文件：

        <property name="prefix" value="/pages/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

在ssm_web下的web.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://xmlns.jcp.org/xml/ns/javaee"

    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
</web-app>

下面是关于Java代码的编写：
1、在ssm_bean的bean包下建一个实体类UserInfo：

package com.zhongruan.bean;
public class UserInfo {
    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 "UserInfo{" +
                "id=" + id +
                ", username='" + username + '\'' +
                ", password='" + password + '\'' +
                '}';
    }
}

2、在ssm_dao的dao包下建立一个接口IUserDao：

package com.zhongruan.dao;
import com.zhongruan.bean.UserInfo;
import java.util.List;
public interface IUserDao {
    public UserInfo doLogin(UserInfo userInfo);     //登录
    public List<UserInfo> findAll();     //用户查询
    public void save(UserInfo userInfo);     添加用户
    public UserInfo getUser(int id);     //查找用户ID
    public int update(UserInfo userInfo);    //修改用户信息
    public void delete(int id);     //删除用户
}

3、在ssm_service的service包下新建一个接口IUserService：

package com.zhongruan.service;
import com.zhongruan.bean.UserInfo;
import java.util.List;
public interface IUserService {
    public boolean doLogin(UserInfo userInfo);
    public List<UserInfo> findAll();
    public void save(UserInfo userInfo);
    public UserInfo getUser(int id);
    public int update(UserInfo userInfo);
    public void delete(int id);
}

4、在ssm_service的service包下建一个impl包，再在其下建一个UserService类：

package com.zhongruan.service.impl;
import com.github.pagehelper.PageHelper;

import com.zhongruan.bean.UserInfo;
import com.zhongruan.dao.IRoleDao;
import com.zhongruan.dao.IUserDao;
import com.zhongruan.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class UserService implements IUserService {
    @Autowired
    private IUserDao userDao;
    @Autowired
    private IRoleDao roleDao;
    @Override
    public boolean doLogin(UserInfo userInfo) {
        UserInfo userInfo1=userDao.doLogin(userInfo);
        if(null!=userInfo1){
            return true;
        }else{
            return false;
        }
    }
    @Override
    public List<UserInfo> findAll() {
        return userDao.findAll();
    }
    @Override
    public void save(UserInfo userInfo) {
        userDao.save(userInfo);
    }
    @Override
    public UserInfo getUser(int id){
        return userDao.getUser(id);
    }
    @Override
    public int update(UserInfo userInfo){
        return userDao.update(userInfo);
    }
    @Override
    public void delete(int id){
        userDao.delete(id);
    }
}

5、在ssm_web的controller包下建一个UserController类：

package com.zhongruan.controller;

import com.github.pagehelper.PageInfo;
import com.zhongruan.bean.UserInfo;
import com.zhongruan.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;
@Controller
@RequestMapping("user")
public class UserController {
    @Autowired
    private IUserService userService;
    @RequestMapping("/login.do")
    public ModelAndView login(UserInfo userInfo){
        ModelAndView mv=new ModelAndView();
        Boolean flag=userService.doLogin(userInfo);
        if(flag){
            mv.setViewName("main");
        }
        else {
            mv.setViewName("../failer");
        }
        return mv;
    }
  @RequestMapping("/findAll.do")
    public ModelAndView findall() {
        List<UserInfo> all = userService.findall();
        ModelAndView mv=new ModelAndView();
        mv.addObject("userInfos", all);
        mv.setViewName("/user-list");//跳转到allUser
        return mv;
    }
    @RequestMapping("/save.do")
    public String save(UserInfo userInfo){
        userService.save(userInfo);
        return "redirect:findAll.do";
    }
    @RequestMapping("/toUpdate.do")
    public ModelAndView toUpdate(int id){
        ModelAndView mv=new ModelAndView();
        UserInfo userInfo=userService.getUser(id);
        mv.addObject("user",userInfo);
        mv.setViewName("user-update");
        return mv;
    }
    @RequestMapping("/update.do")
    public String update(UserInfo userInfo){
        userService.update(userInfo);
        return "redirect:findAll.do";
    }
    @RequestMapping("/delete.do")
    public String delete(int id){
        userService.delete(id);
        return "redirect:findAll.do";
    }
}

6、在ssm_dao的resources下建一个mapper文件夹，在其下建一个UserMapper.xml文件：

<?xml version="1.0" encoding="UTF-8" ?>
        <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.zhongruan.dao.IUserDao" >
<select id="doLogin" parameterType="com.zhongruan.bean.UserInfo"
        resultType="com.zhongruan.bean.UserInfo">
        select * from userinfo where username=#{username} and password=#{password}
    </select>

    <select id="findAll" resultType="com.zhongruan.bean.UserInfo">
        select * from userinfo
    </select>

    <insert id="save" parameterType="com.zhongruan.bean.UserInfo">
        insert into userinfo (id,username,password) values (#{id},#{username},#{password})
    </insert>

    <select id="getUser" parameterType="int" resultType="com.zhongruan.bean.UserInfo">
        select * from userinfo where id=#{id}
    </select>

    <delete id="delete" parameterType="int">
        delete from userinfo where id=#{id}
    </delete>

    <update id="update" parameterType="UserInfo">
        update userinfo
        set username=#{username},password=#{password}
        where id=#{id}
    </update>
</mapper>

各页面的部分设计如下：
1、index.jsp页面，直接跳转到登录页面：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<html>
<body>
<jsp:forward page="/login.jsp"></jsp:forward>
</body>
</html>

2、login.jsp页面，实现登录：

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">

<meta
	content="width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no"

<body class="hold-transition login-page">
	<div class="login-box">
		<div class="login-logo">

		</div>
		<!-- /.login-logo -->
		<div class="login-box-body">

			<a href="#">忘记密码</a><br>
		</div>
		<!-- /.login-box-body -->
	</div>
	<!-- /.login-box -->

	<script

	<script>
		$(function() {
			$('input').iCheck({
				checkboxClass : 'icheckbox_square-blue',
				radioClass : 'iradio_square-blue',
				increaseArea : '20%' // optional

		});
	</script>
</body>
