使用idea2017搭建SSM框架(图文步骤)

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

<?xml version="1.0" encoding="utf-8"?>
<configuration debug="true">

    <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

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

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服务器之家。
