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

</web-app> 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
usercontrollerpackage 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();
}
} iuserdaopackage com.chatrobot.dao;
import com.chatrobot.model.user;
public interface iuserdao {
user selectuser(long id);
} userpackage 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;
}
} iuserservicepackage com.chatrobot.service;
import com.chatrobot.model.user;
public interface iuserservice {
public user selectuser(long userid);
} userserviceimplpackage 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
iuserdaotestpackage 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。
