以上是我發現比較好的兩個搭建框架的博文!下面就詳細介紹一下我搭建SSM框架的過程

安裝和配置JDK1.8,maven3.5.2等就不多說了~ 

配置好maven--> conf -->settings.xml中的映象就好了,我一般用阿里的映象(畢竟快嘛!!)如下圖:

用IDEA搭建SSM框架

我搭建出來的骨架如下:

用IDEA搭建SSM框架

1、途中com.chatRobot用IDEA搭建SSM框架

包的顯示是先將Hide Empty Middle Packages前面對號取消,等到controller等目錄下面的“類”建好後再選中就好了;

2、藍色java用IDEA搭建SSM框架和綠色用IDEA搭建SSM框架以及用IDEA搭建SSM框架要通過配置File -->project structure --->modules --->選中你需要的 然後選擇對應的型別(Sources、Tests、Resources等)如下圖:

用IDEA搭建SSM框架



4、用IDEA搭建SSM框架直接新建xml然後修改型別就好了,如下圖:

5、用IDEA搭建SSM框架這種帶有 綠色葉子狀的xml 檔案需要將spring依賴引入後才能出現

配置pom.xml

到這裡基本上環境就搭建完成了,下面開始測試

四、測試
先匯入一份資料庫測試檔案

CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '使用者ID',
`email` varchar(255) NOT NULL COMMENT '使用者郵箱',
`password` varchar(255) NOT NULL COMMENT '使用者密碼',
`username` varchar(255) NOT NULL COMMENT '使用者暱稱',
`role` varchar(255) NOT NULL COMMENT '使用者身份',
`status` int(1) NOT NULL COMMENT '使用者狀態',
`regTime` datetime NOT NULL COMMENT '註冊時間',
`regIp` varchar(255) NOT NULL COMMENT '註冊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;

接下來配置類

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">

<!-- 設定為IUserDao介面方法提供sql語句配置 -->
<mapper namespace="com.chatRobot.dao.IUserDao">

<select id="selectUser" resultType="User" parameterType="long">
SELECT * FROM user WHERE id = #{id}
</select>

</mapper>

然後新建個測試類,來測試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;

// 載入spring配置檔案
@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());
}

}

執行後結果應該是會在控制檯輸出id為1的使用者名稱,沒成功的話就找BUG去吧...

繼續新建個頁面來測試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>

新建完成後配置專案執行環境,點選Run-Edit Configurations...

點選加號新建執行環境,選擇Tomcat Server-Local

用IDEA搭建SSM框架

接下來選擇tomcat -->Deployment

用IDEA搭建SSM框架

接下來執行專案 就好了
