idea搭建SSM框架

矫情吗；* 2022-04-15 00:43 418阅读 0赞

搭建个SSM框架居然花费了我好长时间！特此记录！

需要准备的环境：

idea 2017.1

jdk1.8

Maven 3.3.9

请提前将idea与Maven、jdk配置好，本次项目用的都是比较新的

注：配置完ide红线报错没关系！可以run！

步骤：

一、首先使用idea新建一个Maven webapp项目

![1028599-20170330133647342-1577021820.png][]

点击Finish，第一次搭建可能会很慢，甚至可能需要VPN才能搭建成功

二、搭建目录结构

我这里列出的是搭建完了之后所有的目录和文件，诸位先把目录文件建起来，然后我在给出文件内容

这里的目录建好之后还需要设置一下，让idea识别目录作用，选择File-Project Structure

设置完成后ok

三、配置文件内容

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"

            </plugins>
        </build>
    
    </project>

注意右下角更新pom

logback.xml

<?xml version="1.0" encoding="UTF-8"?>
    <configuration debug="true">
        <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
            <encoder>
                <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
            </encoder>
        </appender>
        <root level="debug">
            <appender-ref ref="STDOUT"/>
        </root>
    </configuration>

这里可以控制输出格式和内容，有兴趣的可以自己设置

jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
    #数据库地址
    jdbc.url=jdbc:mysql://xxxxxxxxx:3306/ChatRobot?useUnicode=true&characterEncoding=utf8
    #用户名
    jdbc.username=xxxx
    #密码
    jdbc.password=xxxxx
    #最大连接数
    c3p0.maxPoolSize=30
    #最小连接数
    c3p0.minPoolSize=10
    #关闭连接后不自动commit
    c3p0.autoCommitOnClose=false
    #获取连接超时时间
    c3p0.checkoutTimeout=10000
    #当获取连接失败重试次数
    c3p0.acquireRetryAttempts=2

    </web-app>

到这里基本上环境就搭建完成了，下面开始测试

四、测试

先导入一份数据库测试文件

CREATE TABLE `user` (
      `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '用户ID',
      `email` varchar(255) NOT NULL COMMENT '用户邮箱',
      `password` varchar(255) NOT NULL COMMENT '用户密码',
      `username` varchar(255) NOT NULL COMMENT '用户昵称',
      `role` varchar(255) NOT NULL COMMENT '用户身份',
      `status` int(1) NOT NULL COMMENT '用户状态',
      `regTime` datetime NOT NULL COMMENT '注册时间',
      `regIp` varchar(255) NOT NULL COMMENT '注册IP',
      PRIMARY KEY (`id`),
      UNIQUE KEY `email` (`email`) USING BTREE
    ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
    INSERT INTO `user` VALUES ('1', 'xxx', 'xxxxx', 'xxxxx', 'root', '0', '2017-03-28 09:40:31', '127.0.0.1');
    SET FOREIGN_KEY_CHECKS=1;

接下来配置类

UserController

package com.chatRobot.controller;
    
    import javax.servlet.http.HttpServletRequest;
    
    import com.chatRobot.model.User;
    import com.chatRobot.service.IUserService;
    import com.fasterxml.jackson.databind.ObjectMapper;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import javax.annotation.Resource;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    
    @Controller
    @RequestMapping("/user")
    public class UserController {
    
        @Resource
        private IUserService userService;
    
        @RequestMapping("/showUser.do")
        public void selectUser(HttpServletRequest request, HttpServletResponse response) throws IOException {
            request.setCharacterEncoding("UTF-8");
            response.setCharacterEncoding("UTF-8");
            long userId = Long.parseLong(request.getParameter("id"));
            User user = this.userService.selectUser(userId);
            ObjectMapper mapper = new ObjectMapper();
            response.getWriter().write(mapper.writeValueAsString(user));
            response.getWriter().close();
        }
    
    }

IUserDao

package com.chatRobot.dao;
    
    import com.chatRobot.model.User;
    
    public interface IUserDao {
    
        User selectUser(long id);
    
    }

User

package com.chatRobot.model;
    
    import java.util.Date;
    
    public class User {
    
        private long id;
        private String email;
        private String password;
        private String username;
        private String role;
        private int status;
        private Date regTime;
        private String regIp;
    
        public long getId() {
            return id;
        }
    
        public void setId(int id) {
            this.id = id;
        }
    
        public String getEmail() {
            return email;
        }
    
        public void setEmail(String email) {
            this.email = email;
        }
    
        public String getPassword() {
            return password;
        }
    
        public void setPassword(String password) {
            this.password = password;
        }
    
        public String getUsername() {
            return username;
        }
    
        public void setUsername(String username) {
            this.username = username;
        }
    
        public String getRole() {
            return role;
        }
    
        public void setRole(String role) {
            this.role = role;
        }
    
        public int getStatus() {
            return status;
        }
    
        public void setStatus(int status) {
            this.status = status;
        }
    
        public Date getRegTime() {
            return regTime;
        }
    
        public void setRegTime(Date regTime) {
            this.regTime = regTime;
        }
    
        public String getRegIp() {
            return regIp;
        }
    
        public void setRegIp(String regIp) {
            this.regIp = regIp;
        }
    
    }

IUserService

package com.chatRobot.service;
    
    import com.chatRobot.model.User;
    
    public interface IUserService {
    
        public User selectUser(long userId);
    
    }

UserServiceImpl

package com.chatRobot.service.impl;
    
    import com.chatRobot.dao.IUserDao;
    import com.chatRobot.model.User;
    import com.chatRobot.service.IUserService;
    import org.springframework.stereotype.Service;
    
    import javax.annotation.Resource;
    
    @Service("userService")
    public class UserServiceImpl implements IUserService {
    
        @Resource
        private IUserDao userDao;
    
        public User selectUser(long userId) {
            return this.userDao.selectUser(userId);
        }
    
    }

UserDao.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="com.chatRobot.dao.IUserDao">
    
        <select id="selectUser" resultType="User" parameterType="long">
            SELECT * FROM user WHERE id = #{id}
        </select>
    
    </mapper>

然后新建个测试类，来测试mybatis

IUserDaoTest

package com.chatRobot.dao;
    
    import com.chatRobot.model.User;
    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;
    
    // 加载spring配置文件
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration({"classpath:spring-mybatis.xml"})
    public class IUserDaoTest {
    
        @Autowired
        private IUserDao dao;
    
        @Test
        public void testSelectUser() throws Exception {
            long id = 1;
            User user = dao.selectUser(id);
            System.out.println(user.getUsername());
        }
    
    }

运行后结果应该是会在控制台输出id为1的用户名，没成功的话就找BUG去吧...

继续新建个页面来测试springmvc和mybatis

index.html

<!DOCTYPE html>
    <html>
    <head>
        <meta charset="UTF-8">
        <title>test</title>
    </head>
    <script>
        function selectUser() {
            var xmlhttp = new XMLHttpRequest();
            xmlhttp.onreadystatechange = function () {
                if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                    document.getElementById("test").innerHTML = xmlhttp.responseText;
                }
            }
            xmlhttp.open("POST", "user/showUser.do", true);
            xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
            xmlhttp.send("id=1");
        }
    </script>
    <body>
    <p id="test">Hello World!</p>
    <button type="button" onclick="selectUser()">onclick test</button>
    </body>
    </html>

新建完成后配置项目运行环境，点击Run-Edit Configurations...

点击加号新建运行环境，选择Tomcat Server-Local

![1028599-20170330140431014-1273897059.png][]

选中新建好的服务器，右边选择Deployment,点击加号-Atifact...

![1028599-20170330140540920-1603755980.png][]

选择第二项

![1028599-20170330140551592-371587676.png][]

然后在右边Application context配置你的项目名

![1028599-20170330140700936-245748613.png][]

最后运行项目，在打开的页面中点击按钮测试，成功的话会在页面上显示id为1的用户信息
