    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  <!-- 配置前端拦截器 -->
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  </servlet>
  <servlet-mapping>

    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <!-- 配置编码拦截器 -->
  <filter>
    <filter-name>encoding</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>utf-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>encoding</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

第三步：配置springmvc-servlet.xml

首先配置数据库的数据源

dataSource在spring-jdbc-4.2.1.RELEASE.jar的org.springframework.jdbc.datasource的DriverManagerDataSource类

配置spring和mybatis的整合

sqlSessionFactory在mybatis-spring-1.0.0-RC3.jar的org.mybatis.spring.SqlSessionFactoryBean

配置扫描dao 在mybatis-spring-1.0.0-RC3.jar的org.mybatis.spring.mapper.MapperScannerConfigurer

<?xml version="1.0" encoding="UTF-8"?>

      http://www.springframework.org/schema/context/spring-context.xsd  
      http://www.springframework.org/schema/mvc  
      http://www.springframework.org/schema/mvc/spring-mvc.xsd">
      <!-- 开启spring和springmvc的注解 -->       
      <context:component-scan base-package="com.hp"/>
      <mvc:annotation-driven/>
    <!-- 数据库连接数据源 -->

登录实现

第一步：创建数据库和表

create database mydb;
use mydb;

create table userinfo(
  uid int primary key auto_increment,
    username VARCHAR(20) not null,
  password VARCHAR(20) not null,
  truename  VARCHAR(20) not null
);

INSERT INTO userinfo VALUES(null,'tom','123','张三');
INSERT INTO userinfo VALUES(null,'jack','123','李四');
INSERT INTO userinfo VALUES(null,'mark','123','王五');

create table assetinfo(
  aid int primary key auto_increment,
    aname VARCHAR(20) not null,
  model VARCHAR(20) not null,
    price int,
  department  VARCHAR(20) not null,
    producetime date not NULL,
    uid int,
    FOREIGN KEY(uid) REFERENCES userinfo(uid)
);

INSERT INTO assetinfo VALUES(null,'设备1','TX01',300,'开发部','2020-09-09',1);
INSERT INTO assetinfo VALUES(null,'设备2','TX01',400,'研发部','2020-09-09',2);
INSERT INTO assetinfo VALUES(null,'设备3','TX01',500,'开发部','2020-09-09',3);

第二步：创建bean对象

public class Userinfo {
    private Integer uid;
    private String username;
    private String password;
    private String truename;
    //省略get和set方法
}
public class Assetinfo {
    private Integer aid;
    private String aname;
    private String model;
    private Integer price;
    private String department;
    private String producetime;
    private Userinfo userinfo;
     //省略get和set方法
}

第三步：创建dao层和mapper配置文件

import com.hp.bean.Userinfo;

public interface AssinfoDao {
    public Userinfo login(Userinfo userinfo);
}

<?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.hp.dao.AssinfoDao">
    <!-- 登录sql -->
    <select id="login" parameterType="com.hp.bean.Userinfo" resultType="com.hp.bean.Userinfo">
        select * from userinfo where username = #{username} and password = #{password}
    </select>
</mapper>

第四步：创建service层和实现类

import com.hp.bean.Userinfo;

public interface AssetinfoService {
    public Userinfo login(Userinfo userinfo);
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.hp.bean.Userinfo;
import com.hp.dao.AssetinfoDao;
import com.hp.service.AssetinfoService;

@Service
public class AssetinfoServiceImpl implements AssetinfoService{
    @Autowired
    private AssetinfoDao assetinfoDao;
    
    public Userinfo login(Userinfo userinfo) {
        
        return assetinfoDao.login(userinfo);
    }

}

第五步：创建controller控制器

package com.hp.controller;

import javax.servlet.http.HttpSession;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.hp.bean.Userinfo;
import com.hp.service.AssetinfoService;

@Controller
@Scope("prototype")//配置控制器为多例模式
public class AssetinfoController {
	@Autowired
	private AssetinfoService assetinfoService;
	
	/**
	 * 登录功能
	 * @return
	 */
	@RequestMapping("/login")
	public ModelAndView login(Userinfo userinfo, HttpSession session){
		ModelAndView mv = new ModelAndView();
		Userinfo user = assetinfoService.login(userinfo);
		//判断是否成功
		if (null != user) {
			//保存登录信息
			session.setAttribute("userinfo", user);
			mv.setViewName("list");
		}else {
			mv.setViewName("index.jsp");
		}
		return mv;
	}
	
	/**
	 * 列表功能
	 * @return
	 */
	@RequestMapping("/list")
	public ModelAndView list(){
		ModelAndView mv = new ModelAndView("list.jsp");
		return mv;
	}
}

第六步：创建登录页面：

<%@ 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 http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
	<form action="login" method="post">
		用户名：<input type="text" name="username"><br>
		密码：<input type="password" name="password"><br>
		<input type="submit" value="登录">
	</form>
</body>
</html>

列表实现

第一步：在AssetinfoDao接口添加查询所有的方法findAll,在AssetinfoMapper添加对应sql

import java.util.List;

import com.hp.bean.Assetinfo;
import com.hp.bean.Userinfo;

public interface AssetinfoDao {
	//登录功能
	public Userinfo login(Userinfo userinfo);
	//查询列表
	public List<Assetinfo> findAll();
}

<?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.hp.dao.AssetinfoDao">
	<!-- 创建resultMap -->
	<resultMap type="com.hp.bean.Assetinfo" id="baseMap">
		<id column="aid" property="aid"/>
		<result column="aname" property="aname"/>
		<result column="model" property="model"/>
		<result column="price" property="price"/>
		<result column="department" property="department"/>
		<result column="producetime" property="producetime"/>
		<!-- 配置一对一关系 -->
		<association property="userinfo" javaType="com.hp.bean.Userinfo" column="uid">
			<id column="uid" property="uid"/>
			<result column="truename" property="truename"/>
		</association>
	</resultMap>
	<!-- 登录sql -->
	<select id="login" parameterType="com.hp.bean.Userinfo" resultType="com.hp.bean.Userinfo">
		select * from userinfo where username = #{username} and password = #{password}
	</select>
	<!-- 查询所有sql -->
	<select id="findAll" resultMap="baseMap">
		select * from assetinfo a, userinfo u where a.uid = u.uid
	</select>
</mapper>

第二步：在AssetinfoService中添加findALl方法并在实现类中调用dao的findAll方法

import java.util.List;

import com.hp.bean.Assetinfo;
import com.hp.bean.Userinfo;

public interface AssetinfoService {
	//登录功能
	public Userinfo login(Userinfo userinfo);
	//查询列表
	public List<Assetinfo> findAll();
}

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.hp.bean.Assetinfo;
import com.hp.bean.Userinfo;
import com.hp.dao.AssetinfoDao;
import com.hp.service.AssetinfoService;

@Service
public class AssetinfoServiceImpl implements AssetinfoService{
	@Autowired
	private AssetinfoDao assetinfoDao;
	
	public Userinfo login(Userinfo userinfo) {
		return assetinfoDao.login(userinfo);
	}

	@Override
	public List<Assetinfo> findAll() {
		return assetinfoDao.findAll();
	}

}

第三步：在AssetinfoController在查询所有的方法list中实现

@Controller @Scope("prototype")//配置控制器为多例模式 public class AssetinfoController { @Autowired private AssetinfoService assetinfoService;

/**
 * 登录功能
 * @return
 */
@RequestMapping("/login")
public ModelAndView login(Userinfo userinfo, HttpSession session){
	ModelAndView mv = new ModelAndView();
	Userinfo user = assetinfoService.login(userinfo);
	//判断是否成功
	if (null != user) {
		//保存登录信息
		session.setAttribute("userinfo", user);
		mv.setViewName("list");
	}else {
		mv.setViewName("index.jsp");
	}
	return mv;
}

/**
 * 列表功能
 * @return
 */
@RequestMapping("/list")
public ModelAndView list(){
	ModelAndView mv = new ModelAndView("list.jsp");
	//查询所有列表
	List<Assetinfo> list = assetinfoService.findAll();
	//向页面传值
	mv.addObject("list", list);
	return mv;
}

}

第四步：页面布局

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<title>Insert title here</title>
<style type="text/css">
	table{
		background: gray;
		margin: 50px auto;
		width: 60%;
	}
	th,td{
		background: white;
		padding: 4px;
	}
</style>
</head>
<body>
	<table>
		<tr>
			<td colspan="7">

	</table>
</body>
</html>

添加实现

第一步：在AssetinfoDao接口添加查询所有的方法findAll,在AssetinfoMapper添加对应sql

	//添加方法
	public int add(Assetinfo assetinfo);

<!-- 添加sql -->
	<insert id="add" parameterType="com.hp.bean.Assetinfo">

/**
	 * 添加功能
	 * @return
	 */
	@RequestMapping("/add")
	public ModelAndView add(Assetinfo assetinfo, HttpSession session){

		//获取登录人信息
		Userinfo userinfo = (Userinfo) session.getAttribute("userinfo");
		//保存到assetinfo对象里面
		assetinfo.setUserinfo(userinfo);
		//执行添加
		int i = assetinfoService.add(assetinfo);
		if (i > 0) {
			mv.setViewName("list");
		}else {
			mv.setViewName("add.jsp");
		}
		return mv;
	}

第四步：页面布局

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