前言

为何要写？

首先声明这是一个非常简单的项目，只包含注册和登录。

有人说了，这么简单的项目，我瞧不上。确实！对于一些高手来说，这点东西不过是毛毛雨。

但是对于一个初学者来说，有一个简单易上手的项目可以吧mybatis+Servlet+Mysql 整合起来，对于自己的学习不可不算是一个良好的契机。

学以致用，本文章旨在检验前面系列文章是否写的合格，结果是：

理论性太强，而实践太散，所以借着这篇文章，把实践的方便加强

目录结构

1 依赖配置

1.1 创建一个WEB项目

不会的可以看这篇文章 Http://t.csdn.cn/UahZN

1.2 依赖需求分析

mybatis+Servlet很显然需要用到二者的依赖，mybatis需要连接数据库，所以需要数据库的依赖，数据库则需要实体类，为了简便开发引入Lombok依赖。想要使用单元测试，则还需要引入junit依赖。

所以总共需求如下依赖

• mybatis

• servlet

• mysql

• lombok

• junit

1.3 pom.xml

<project xmlns="http://Maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0modelVersion>  <groupId>com.yougroupId>  <artifactId>javaweb-Demo-06artifactId>  <version>1.0-SNAPSHOTversion>  <packaging>warpackaging>  <name>JavaWeb-Demo-06 Maven Webappname>    <url>http://www.example.comurl>  <properties>    <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>    <maven.compiler.source>1.7maven.compiler.source>    <maven.compiler.target>1.7maven.compiler.target>  properties>  <dependencies>    <dependency>      <groupId>junitgroupId>      <artifactId>junitartifactId>      <version>4.11version>      <scope>testscope>    dependency>        <dependency>      <groupId>org.mybatisgroupId>      <artifactId>mybatisartifactId>      <version>3.5.7version>    dependency>        <dependency>      <groupId>org.projectlombokgroupId>      <artifactId>lombokartifactId>      <version>1.18.24version>    dependency>        <dependency>      <groupId>javax.servletgroupId>      <artifactId>javax.servlet-apiartifactId>      <version>3.1.0version>      <scope>providedscope>    dependency>        <dependency>      <groupId>mysqlgroupId>      <artifactId>mysql-connector-javaartifactId>      <version>8.0.30version>    dependency>  dependencies>  <build>    <finalName>JavaWeb-Demo-06finalName>    <pluginManagement>      <plugins>        <plugin>          <artifactId>maven-clean-pluginartifactId>          <version>3.1.0version>        plugin>                <plugin>          <artifactId>maven-resources-pluginartifactId>          <version>3.0.2version>        plugin>        <plugin>          <artifactId>maven-compiler-pluginartifactId>          <version>3.8.0version>        plugin>        <plugin>          <artifactId>maven-surefire-pluginartifactId>          <version>2.22.1version>        plugin>        <plugin>          <artifactId>maven-war-pluginartifactId>          <version>3.2.2version>        plugin>        <plugin>          <artifactId>maven-install-pluginartifactId>          <version>2.5.2version>        plugin>        <plugin>          <artifactId>maven-deploy-pluginartifactId>          <version>2.8.2version>        plugin>      plugins>    pluginManagement>  build>project>

2 配置Mybatis

参考自自己的文章《Mybatis的快速入门》 http://t.csdn.cn/3SXlb 《Mybatis的代理开发》http://t.csdn.cn/Bt8Xi

2.1 mybatis-config.xml

mybatis-config配置，主要包括两个点：

• **数据库配置：**数据库名称、JDBC、数据库用户名和密码
• Mapper：让Mybatis找到Mapper.xml

DOCTYPE configuration        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"        "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>    <environments default="development">        <environment id="development">            <transactionManager type="JDBC"/>            <dataSource type="POOLED">                <property name="driver" value="com.mysql.cj.jdbc.Driver"/>                <property name="url" value="jdbc:mysql://localhost:3306/us80?useSSL=false&serverTimezone=UTC"/>                <property name="username" value="root"/>                <property name="passWord" value="200201203332"/>            dataSource>        environment>    environments>    <mappers>        <package name="com/you/Mapper"/>    mappers>configuration>

2.2 UserMapper.xml

这个知识点是漏网之鱼，没有意识到即使是使用注解配置sql语句，也需要接口绑定。

DOCTYPE mapper        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"        "http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.you.Mapper.UserMapper">mapper>

2.3 UserMapper.interface

package com.you.Mapper;import com.you.Dept.User;import org.apache.ibatis.annotations.Insert;import org.apache.ibatis.annotations.Param;import org.apache.ibatis.annotations.Select;import java.util.List;public interface UserMapper {    @Select("select * from user where user_name = #{user_name} and user_pwd = #{user_pwd}")    public User selectUserByInfo(@Param("user_name") String user_name,@Param("user_pwd") String user_pwd);    @Select("select * from user")    public List<User> queryAllUsers();    @Insert("insert into user values(null,#{user_name},#{user_pwd},#{user_emil})")    public boolean reGISterUser(@Param("user_name") String user_name,@Param("user_pwd") String user_pwd,@Param("user_emil") String user_emil);}

3 配置Tomcat

参考本人的文章 《idea集成Tomcat》 http://t.csdn.cn/6Uma5

4 Servlet类

4.1 loginServlet01

处理登录的功能，需要注意的点：

1. JavaWeb_Demo_06_war是自己的虚拟目录，每个人配置的都不一样 Tomcat文章中提到了
2. Mybatis的缺点：和数据库交互时都需要重新连接数据库
3. request获取数据的时候，要设置编码为UTF-8，不然会乱码

package com.you.request;import com.you.Dept.User;import com.you.Mapper.UserMapper;import org.apache.ibatis.io.Resources;import org.apache.ibatis.session.SqlSession;import org.apache.ibatis.session.SqlSessionFactory;import org.apache.ibatis.session.SqlSessionFactoryBuilder;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.httpservlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.io.IOException;import java.io.InputStream;import java.io.PrintWriter;import java.util.Timer;import java.util.TimerTask;@WebServlet(urlPatterns = "/login")public class loginRequset01 extends HttpServlet {    @Override    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {                System.out.println("进来！！！");        req.setCharacterEncoding("UTF-8");        String username = req.getParameter("username");        String password = req.getParameter("password");        System.out.println("用户名:"+username);        System.out.println("密码:"+password);        String resource = "mybatis-config.xml";        InputStream inputStream = null;        inputStream = Resources.getResourceAsStream(resource);        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);        SqlSession sqlSession = sqlSessionFactory.openSession();        UserMapper mapper = sqlSession.getMapper(UserMapper.class);        User user1 = mapper.selectUserByInfo(username,password);        resp.setContentType("text/html;charset=UTF-8");        PrintWriter writer = resp.getWriter();        if(user1!=null)        {            resp.sendRedirect("/JavaWeb_Demo_06_war/index.html");        }else{            resp.sendRedirect("/JavaWeb_Demo_06_war/errorPage.html");        }    }    @Override    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {        this.doGet(req,resp);    }}

4.2 registerRequest01

处理注册的功能，需要注意的点：

1. 修改数据库（update、insert）时，需要提交(commit)才能生效

package com.you.request;import com.you.Dept.User;import com.you.Mapper.UserMapper;import org.apache.ibatis.io.Resources;import org.apache.ibatis.session.SqlSession;import org.apache.ibatis.session.SqlSessionFactory;import org.apache.ibatis.session.SqlSessionFactoryBuilder;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.io.IOException;import java.io.InputStream;import java.io.PrintWriter;@WebServlet("/registerRequest01")public class registerRequest01 extends HttpServlet {    @Override    protected void doGet(final HttpServletRequest req, final HttpServletResponse resp) throws ServletException, IOException {                req.setCharacterEncoding("UTF-8");        String username = req.getParameter("username");        String password = req.getParameter("password");        String useremail = req.getParameter("useremail");                String resource = "mybatis-config.xml";        InputStream inputStream = null;        inputStream = Resources.getResourceAsStream(resource);        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);        SqlSession sqlSession = sqlSessionFactory.openSession();                UserMapper mapper = sqlSession.getMapper(UserMapper.class);        boolean user = mapper.registerUser(username, password, useremail);        resp.setContentType("text/html;charset=UTF-8");        PrintWriter writer = resp.getWriter();        if(user!=false)        {            sqlSession.commit();            resp.sendRedirect("/JavaWeb_Demo_06_war/transmitPage.html");        }else{        }    }    @Override    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {        this.doGet(req,resp);    }}
