用ssm框架在idea上搭建javaWeb maven项目

一、在idea创建一个web maven项目

1.首先创建一个新maven项目
创建一个新的项目
在这里插入图片描述
注：不要选错，有两个webapp，选前面带maven的那个

选择自己的maven的本地仓库

填写项目名称和位置，点击finish

进来之后可以看到build success，点击右边出现的提示：点击enable auto-Import以后更改pom文件后就会自动下载依赖包了
在这里插入图片描述

二、配置tomcat

在这里插入图片描述

三、项目配置

1.先建好如下文件结构，其中将Java文件夹作为资源文件（右击选择mark directory as，选择 source root），将test文件夹作为测试文件夹（同上，选择test source root），将resource文件夹作为配置资源文件（同上，选择Resource root）
在这里插入图片描述
2.分别配置各个配置文件

import zhn.dao.UserMapper;
import zhn.entity.User;
import zhn.service.UserService;

/**
 * @Author:zhn
 * @Date:2018/12/14
 */
@Service
public class UserServiceImpl implements UserService{

    @Autowired
    private UserMapper userMapper;

    @Override
    public User login( User user ) {
        User user1 = userMapper.login(user);
        return user1;
    }
}

可以在写controller代码之前测试一下前面的配置以及service对不对，在test文件夹下建一个类：UserTest
//UserTest

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import zhn.entity.User;
import zhn.service.UserService;

/**
 * @Author:zhn
 * @Date:2018/12/14
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(value = {"classpath:spring-mybatis.xml"})
public class UserTest {
    @Autowired
    UserService userService = null;

    @Test
    public void TestLogin(){
        User user = new User();
        user.setUsername("root");
        user.setUserpass("root");
        User user1 = userService.login(user);
        System.out.println(user1);

    }
}

而且，看到这个绿色圆形带有一个向右箭头，说明自动注入成功
在这里插入图片描述
可以运行一下测试类，看看有没有登陆成功

如果控制台出现下面提示，就说明运行成功

接着，写controller代码
//controller.UserController

package zhn.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import zhn.entity.User;
import zhn.service.UserService;

import java.util.Map;

/**
 * @Author:zhn
 * @Date:2018/12/14
 */
@Controller
@RequestMapping("/userController")
public class UserController {

    @Autowired
    UserService userService;

    @RequestMapping(value = "/{url}", method = RequestMethod.GET)
    public String getPage( @PathVariable("url") String url ) {
        if (url != null) {
            return url;
        }
        return "error";
    }

    @RequestMapping(value = "/login",method = RequestMethod.POST)
    public String login( User user, Map map){
        String url="";
        User user1 = userService.login(user);
        if(user1!=null){
            map.put("user",user1);
            url="success";
        }else{
            url="error";
        }
        return url;
    }
}

下面是jsp页面
先贴一下jsp页面的结构，在WEB-INFO下建一个文件夹myjsp，把jsp文件都放到此文件夹下，这样外部通过URL是访问不到的
在这里插入图片描述
//webapp.index.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%
    String path = request.getContextPath();
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<html>
<head>
    <base href="<%=basePath%>">
    <title>主页</title>
</head>
<body>
<%response.sendRedirect(path+"userController/login");%>
</body>
</html>

//login.jsp

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

<body>
<div style="width:100%;text-align:center">

    <form action="${pageContext.request.contextPath}/userController/login" method="post" >
        <div class="text-user">
            <input name="username" type="text" placeholder="用户名">
        </div>
        <div>
            <input name="userpass" type="password" placeholder="密码">
        </div>
        <div class="btn">
            <button type="submit">登录</button>
        </div>
    </form>
</div>
</body>
</html>

//success.jsp

出现以上页面，说明登录成功，同时也说明ssm框架搭建成功！
