eclipse创建ssm项目详细步骤
1.环境搭建
点击File->new->Maven Project。选中Create a simple project.然后点击next。
填写Group Id和Artifact Id,然后选择Packaging为war包。然后点击finish完成创建。
右击项目，选择Properties->Project Facets.将java版本改为9；然后取消Dynamic Web Module复选框，并点击Apply;接着选中Dynamic Web Module,此时会出现一个链接，点击链接
将Content directory改为src/main/webapp，然后选中Generate web.xml。点击ok创建完成。
创建好的目录如下
2.配置文件
- 在pom.xml配置自己需要的依赖

- 在src/main/webapp/WEB-INF目录中，配置web.xml
<web-app id="WebApp_ID" version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

- 在src/main/webapp/WEB-INF下配置SpringMVC配置文件 dispatcherServlet-servlet.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"

- 在src/main/resources目录中，配置数据库配置文件 dbconfig.properties
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/数据库名
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=数据库登录名
jdbc.password=密码
- 在src/main/resources目录中，配置Spring配置文件 applicationContext.xml
<beans xmlns="http://www.springframework.org/schema/beans"

3.创建测试
1.创建实体类
在src/main/java目录下，新建一个com.my.pojo包
package com.my.pojo;
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;
}
}
2.数据访问层
在src/main/java目录下，创建com.my.dao包
package com.my.dao;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import com.my.pojo.UserInfo;
public interface UserInfoDao {
// 根据用户名和密码查询
@Select("select * from user_info where userName = #{userName} and password = #{password}")
public UserInfo findUserInfoByCond(@Param("userName") String userName, @Param("password") String password);
}
3.业务逻辑层
在src/main/java目录下，创建com.my.service包
package com.my.service;
import com.my.pojo.UserInfo;
public interface UserInfoService {
public UserInfo login(String userName, String password);
}
在service包下新建impl子包实现service包的类
package com.my.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.my.dao.UserInfoDao;
import com.my.pojo.UserInfo;
import com.my.service.UserInfoService;
@Service("userInfoService")
public class UserInfoServiceImpl implements UserInfoService {
@Autowired
private UserInfoDao userInfoMapper;
public UserInfo login(String userName, String password) {
return userInfoMapper.findUserInfoByCond(userName, password);
}
}
4.控制器
在src/main/java目录下，创建com.my.controller包
package com.my.controller;
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 org.springframework.web.bind.annotation.RequestMethod;
import com.my.pojo.UserInfo;
import com.my.service.UserInfoService;
@Controller
@RequestMapping("/userinfo")
public class UserInfoController {
@Autowired
private UserInfoService userInfoService;
@RequestMapping(value="/login",method= {RequestMethod.POST,RequestMethod.GET})
public String login(UserInfo ui, Model model) {
UserInfo tempUi = userInfoService.login(ui.getUserName(), ui.getPassword());
if (tempUi != null && tempUi.getUserName() != null) {
model.addAttribute("user", tempUi);
return "index";
} else {
return "redirect:/login.jsp";
}
}
}
5.表示层
在src/main/webapp下，新建登录页login.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title heretitle>
head>
<body>
<form action="userinfo/login" method="post">
<table>
<tr>
<td>用户名：td>
<td><input type="text" name="userName" />td>
tr>
<tr>
<td>密 码：td>
<td><input type="text" name="password" />td>
tr>
<tr>
<td><input type="submit" value="登录" />td>
<td>td>
tr>
table>
form>
body>
html>
再新建一个跳转页index.jsp，表示登录成功
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title heretitle>
head>
<body>
${requestScope.user.userName }欢迎您，登录成功！！！
body>
html>
4.运行
右击项目，Build Path->Configure Build Path…->Libraries->Add Library…
选择Server Runtime,点击next
选择已下载的Tomcat，点击Finish,点击Apply and Close
右击项目，Run As->1 Run on Server,点击Finish启动。
输入http://localhost:8080/ssmDemo/login.jsp
输入账号密码，点击登录，成功跳转，测试成功。
