使用idea2017搭建SSM框架(图文步骤)

这篇文章主要介绍了使用idea2017搭建SSM框架(图文步骤)，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧
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




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

    <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

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 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
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持CodeAE代码之家。
