本文详述了如何在Java环境下，使用Maven构建SSM（Spring、SpringMVC、MyBatis）项目，并整合Druid数据源。步骤包括创建Maven Web项目，配置Tomcat服务器，调整项目目录结构，编写pom.xml，创建login和index页面，以及配置web.xml。完成这些步骤后，通过Maven构建并测试项目的运行。

环境:jdk1.8,tomcat8.5,eclipse,有错认真解决,千万别急.

创建maven项目,next

选择webapp结尾的

输入对应的id, finish

创建出的maven项目如下图

在eclipse中设置Server为Tomcat，注意JRE设置为安装的JDK的jre

在工程上右键，查看工程属性，找到Java Build Path，添加Server Runtime为Tomcat

默认的Dynamic Web Module为2.3，使用Tomcat 8.5，需要修改为3.1 自行百度目录结构少的可以手动添加

项目结构:

编写User实体类

package cn.temptation.domain;

public class User {
	
	// 成员变量
	 private Integer userid;
	 private String username;
	 private String password;
	 // 构造函数
	 public User() {
	  super();
	 }
	 public User(Integer userid, String username, String password) {
	  super();
	  this.userid = userid;
	  this.username = username;
	  this.password = password;
	 }
	 // 成员方法
	 public Integer getUserid() {
	  return userid;
	 }
	 public void setUserid(Integer userid) {
	  this.userid = userid;
	 }
	 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;
	 }
}

编写UserController控制器

package cn.temptation.web;

import javax.annotation.Resource;
import javax.servlet.http.HttpSession;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import cn.temptation.dao.UserDao;
import cn.temptation.domain.User;

@Controller
@RequestMapping(value = "/user")
public class UserController {
	@Resource
	 private UserDao userDao;
	 @RequestMapping("/view")
	 public String view() {
	  return "main/login";
	 }
	 @RequestMapping("/indexview")
	 public String index() {
	  return "main/index";
	 }
	 @RequestMapping(value = "/login", method = RequestMethod.POST)
	 public ModelAndView login(User model, HttpSession session) {
	  User user = userDao.findByUsername(model.getUsername());
	  if (user == null || !user.getPassword().equals(model.getPassword())) {
	   return new ModelAndView("redirect:/login.jsp");
	  } else {
	   session.setAttribute("user", user);
	   ModelAndView mav = new ModelAndView();
	   mav.setViewName("index");
	   return mav;
	  }
	 }
}

编写UserDao数据访问层接口

package cn.temptation.dao;

import cn.temptation.domain.User;

public interface UserDao {
	public User findByUsername(String username);
}

编写UserMapper.xml

<?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="cn.temptation.dao.UserDao">
 <select id="findByUsername" parameterType="String" resultType="cn.temptation.domain.User">
  	SELECT * FROM userinfo WHERE username=#{username}
 </select>
</mapper>

webapp下新建login和index

<%@ 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>登录</title>
</head>
<body>
<form action="user/login.do" method="post">
<label>账号：</label>
<input type="text" id="txtUsername" name="username" placeholder="请输入账号" /><br/>
<label>密码：</label>
<input type="password" id="txtPassword" name="password" placeholder="请输入密码" /><br/>
<input type="submit" value="提交" />
<input type="reset" value="重置" />
</form>
</body>
</html>

index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>主页</title>
</head>
<body>
<h3>欢迎，${user.username }</h3>
</body>
</html>

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"

	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- 配置SpringMVC环境 -->
	<servlet>

		</init-param>
	</servlet>
	<servlet-mapping>
		<servlet-name>springMVC</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>



</web-app>

可以先update一下不嫌麻烦可以 maven install一下看看是否能build成功

然后就可以运行了
