使用idea搭建SSM框架

绝地灬酷狼 2022-06-06 07:10 282阅读 0赞

环境：

idea 2017.1

jdk1.8

Maven 3.3.9

步骤：

一、新建Maven webapp项目

![1028599-20170330133558811-1365797169.png][]

![1028599-20170330133622139-1403001733.png][]

![1028599-20170330133635654-502904805.png][]

![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、项目目录结构

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

![1028599-20170330134119920-351921480.png][]

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

![1028599-20170330134447826-929310673.png][]

设置完成后ok

三、配置文件内容

pom.xml

注意右下角更新pom

logback.xml

![复制代码][copycode.gif]

<?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>

![复制代码][copycode.gif]

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

![复制代码][copycode.gif]

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

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

![复制代码][copycode.gif]

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;

![复制代码][copycode.gif]

接下来配置类

UserController

![复制代码][copycode.gif]

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(); } }

![复制代码][copycode.gif]

IUserDao

![复制代码][copycode.gif]

package com.chatRobot.dao;

import org.springframework.stereotype.Repository import com.chatRobot.model.User;

@Repository public interface IUserDao { User selectUser(long id); }

![复制代码][copycode.gif]

User

![复制代码][copycode.gif]

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; } }

![复制代码][copycode.gif]

IUserService

![复制代码][copycode.gif]

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

![复制代码][copycode.gif]

UserServiceImpl

![复制代码][copycode.gif]

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); } }

![复制代码][copycode.gif]

UserDao.xml

![复制代码][copycode.gif]

<?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>

![复制代码][copycode.gif]

然后新建个测试类，来测试mybatis

IUserDaoTest

![复制代码][copycode.gif]

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()); } }

![复制代码][copycode.gif]

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。

![1028599-20170330140048873-1889210725.png][]

继续新建个页面来测试springmvc和mybatis

index.html

![复制代码][copycode.gif]

<!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>

![复制代码][copycode.gif]

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
