使用idea搭建SSM框架

2021-09-17 08:40:45

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

　　使用idea搭建SSM框架

　　使用idea搭建SSM框架

　　使用idea搭建SSM框架

　　使用idea搭建SSM框架

　　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

　　使用idea搭建SSM框架

　　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

　　使用idea搭建SSM框架

　　设置完成后ok

三、配置文件内容

pom.xml

使用idea搭建SSM框架

注意右下角更新pom

logback.xml

使用idea搭建SSM框架
<?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>
使用idea搭建SSM框架

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

使用idea搭建SSM框架
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

#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

#当获取连接失败重试次数

</web-app>
使用idea搭建SSM框架

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

使用idea搭建SSM框架
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;
使用idea搭建SSM框架

接下来配置类

UserController

使用idea搭建SSM框架
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();

    }

}
使用idea搭建SSM框架

IUserDao

使用idea搭建SSM框架
package com.chatRobot.dao;

import com.chatRobot.model.User;

public interface IUserDao {

    User selectUser(long id);

}
使用idea搭建SSM框架

User

使用idea搭建SSM框架
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;

    }

}
使用idea搭建SSM框架

IUserService

使用idea搭建SSM框架
package com.chatRobot.service;

import com.chatRobot.model.User;

public interface IUserService {

    public User selectUser(long userId);

}
使用idea搭建SSM框架

UserServiceImpl

使用idea搭建SSM框架
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);

    }

}
使用idea搭建SSM框架

UserDao.xml

使用idea搭建SSM框架
<?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">

<!-- 设置为IUserDao接口方法提供sql语句配置 -->

<mapper namespace="com.chatRobot.dao.IUserDao">

    <select id="selectUser" resultType="User" parameterType="long">

        SELECT * FROM user WHERE id = #{id}

    </select>

</mapper>
使用idea搭建SSM框架

然后新建个测试类，来测试mybatis

IUserDaoTest

使用idea搭建SSM框架
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());

    }

}
使用idea搭建SSM框架

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...

使用idea搭建SSM框架

继续新建个页面来测试springmvc和mybatis

index.html

使用idea搭建SSM框架
<!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>
使用idea搭建SSM框架

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

使用idea搭建SSM框架

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

使用idea搭建SSM框架

选择第二项

使用idea搭建SSM框架

然后在右边Application context配置你的项目名

使用idea搭建SSM框架

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

使用idea搭建SSM框架

点击onclick 事件效果如下：

使用idea搭建SSM框架

大功告成，希望对大家学习java中ssm框架有帮助。
