使用idea 搭建ssm+maven+logback项目

来源：互联网发布：win7下nginx配置php 编辑：程序博客网时间：2024/05/18 23:26

第一次学习搭建ssm框架，也是边学习边实践参考这篇博客，特此记录

需要准备的环境：

　　idea 2017.2

　　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

　　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

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

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"><!-- 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>

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

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

选择第二项

然后在右边Application context配置你的项目名

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
