最新版的SSM框架spring5.0搭建教程(附原始碼)
用SSM框架已經有一段時間了,但都沒有完整地搭建過一次工程。前段時間比較有時間就自己試著搭建了一下,差不多都是用的最新的spring版本了,然後就在這個基礎上做了很多的實驗測試。最近想著還是記錄一下整個搭建的過程,以便於自己日後參考。所以就重新翻新了一下,為了寫得儘可能地詳細點所以內容有點多。
GitHub的原始碼地址:SSMDemo GitHub原始碼
我是用的idea這個軟體搭建的,我也一直使用的這個軟體,非常好用,很適合做Java的朋友。
1.建立一個maven的web工程。
為了方便我儘可能地上截圖了。
建立maven的web工程
專案名稱
配置maven
上面的操作就完成了建立工程的基本操作了。
2.建立工程的包結構
建立好各層的測試類和常規的配置檔案
整個工程的包結構就建立完成了。
3.導包,這是非常重要的一步,需要將我們使用的spring、springMVC和MyBatis的相關包都導進來,直接使用maven依賴。
直接上pom.xml的原始碼:
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

然後等待idea自動下載一堆jar的包,如果沒有自動下載的可以點這裡:
所有的包下載完成後控制檯會有提示的。
*4.配置spring、spring和MyBatis的整合配置檔案,最重要的一步也是最麻煩的一步同樣也是最難的一步。不過不要怕,我們一步一步慢慢來。
這裡內容有點多,就不多說啥了,直接粘程式碼,需要的複製過去就OK了。

web.xml檔案也是需要配置的,原始碼如下:

log4j相信大家都不陌生,在專案中我們常常會用到日誌,因此非常有必要配置一下日誌資訊。
log4j.properties原始碼如下:
log4j.rootLogger = DEBUG,Console,File
log4j.appender.Console = org.apache.log4j.ConsoleAppender
#log4j.appender.Console.Target = System.out
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern = %5p %d %C: %m%n
#每天列印一個日誌檔案
log4j.appender.File = org.apache.log4j.DailyRollingFileAppender
log4j.appender.File.File=E:/logs/SSMDemo.log
log4j.appender.File.Encoding=UTF-8
#列印所有級別的日誌資訊
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =%d{ABSOLUTE} %5p %c{1}\:%L - %m%n
log4j.logger.com.opensymphony=ERROR
log4j.logger.org.springframework=ERROR
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=INFO
log4j.logger.java.sql.PreparedStatement=INFO
log4j.logger.java.sql.ResultSet=INFO
log4j.logger.java.sql.Statement=INFO
jdbc也是必不可少的一部分,畢竟資料都是來源於資料庫的嘛。
jdbc.properties原始碼如下:
#開發環境
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mydatabase_test
jdbc.user=your username
jdbc.password=your password
到這裡我們的配置檔案就算說完了(當然這是最基礎的需要,SSM的功能十分強大,還可以嵌入很多很多的功能...)
5.依葫蘆畫瓢,編寫各層的功能類即可,controller層主要寫http請求的介面方法,service主要寫各種業務操作演算法等,mapper層也可以稱為dao層(我的習慣是寫成mapper層)主要是寫對映到資料庫的方法介面,**Mapper.xml檔案主要是寫mapper層中的介面功能的SQL語句實現。這樣的分層管理應該可以相容各種大大小小的專案了。
下面也貼上我的工程中各層的測試程式碼。
model實體類:
package com.ssm.model;
/**
* created by viking on 2018/07/04
* user實體類
*/
public class User {
private int id;
private String name;
private int age;
private String sex;
public User() {
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", name='" + name + '\'' +
", age=" + age +
", sex='" + sex + '\'' +
'}';
}
}
controller層:
package com.ssm.controller;
import com.ssm.model.User;
import com.ssm.service.UserService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
/**
* created by viking on 2018/07/04
* controller層介面類
*/
@RestController
@RequestMapping("user")
public class UserController {
@Autowired
private UserService userService;
Logger log = Logger.getLogger(UserController.class);
@RequestMapping("select")
@ResponseBody
public Object userTest(int id){
System.out.println("測試成功~~"+id);
List<User> user = userService.getUser(id);
System.out.println(user.toString());
log.info(user);
return user;
}
@RequestMapping("addUser")
public Object insertUser(int id,String name,int age,String sex){
userService.insertUser(id,name,age,sex);
return "OK";
}
@RequestMapping("selectAll")
public Object selectAll(){
return userService.selectAll();
}
@RequestMapping("update")
public Object update(){
return userService.update();
}
}
service層(service層一般都是比較複雜的,因此我習慣分成介面和實現類兩部分)介面:
package com.ssm.service;
import com.ssm.model.User;
import java.util.List;
/**
* created by viking on 2018/07/04
* 業務層介面
*/
public interface UserService {
List<User> getUser(int id);
void insertUser(int id, String name, int age, String sex);
List<User> selectAll();
Object update();
}
service層實現類:
package com.ssm.service.impl;
import com.ssm.mapper.UserMapper;
import com.ssm.model.User;
import com.ssm.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
/**
* created by viking on 2018/07/04
* 業務層介面實現類
*/
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserMapper userMapper;
public List<User> getUser(int id) {
Map map = new HashMap();
map.put("id",id);
return userMapper.getUser(map);
}
public void insertUser(int id, String name, int age, String sex) {
Map param = new HashMap();
param.put("id",id);param.put("name",name);
param.put("age",age);param.put("sex",sex);
userMapper.insertUser(param);
}
public List<User> selectAll() {
return userMapper.selectAll();
}
public Object update() {
Map param = new HashMap();
param.put("total",10);
param.put("name","測試一");
userMapper.update(param);
return "OK";
}
}
mapper層(dao層)介面:
package com.ssm.mapper;
import com.ssm.model.User;
import org.apache.ibatis.annotations.Param;
import java.util.List;
import java.util.Map;
/**
* created by viking on 2018/07/04
* dao層介面
*/
public interface UserMapper {
List<User> getUser(@Param("param") Map map);
void insertUser(@Param("param") Map param);
List<User> selectAll();
void update(@Param("param") Map param);
}
**Mapper.xml MaBatsis對映檔案配置檔案,相當於mapper層介面的實現類了:
<?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">
<mapper namespace="com.ssm.mapper.UserMapper">
<select id="getUser" parameterType="java.util.Map" resultType="com.ssm.model.User">
SELECT *
FROM user
where id =#{param.id}
</select>
<insert id="insertUser" parameterType="java.util.Map">
INSERT INTO user (id,name,age,sex) values(#{param.id},#{param.name},#{param.age},#{param.sex})
</insert>
<select id="selectAll" resultType="com.ssm.model.User">
SELECT * FROM USER
</select>
<update id="update" parameterType="java.util.Map">
UPDATE USER SET id=id-#{param.total},age=age+#{param.total}
WHERE name=#{param.name}
</update>
</mapper>
為了方便大家拷下程式碼後可以直接啟動,我把資料庫的sql語句和資料也貼上,我用的是mysql資料庫:
/*
Navicat MySQL Data Transfer
Source Server : mysql
Source Server Version : 50173
Source Host : localhost:3306
Source Database : mydatabase_test
Target Server Type : MYSQL
Target Server Version : 50173

我本地的資料庫表結構截圖:
到這裡就完全結束了,整個工程就可以直接運行了。
6.順帶提一下在idea中配置tomcat的過程(懂的朋友可以直接忽略~)
配置好了之後再將tomcat新增到server中:
好了~tomcat的配置也完成了。
7.下面貼上我的本機執行效果圖:
tomcat成功啟動:
通過瀏覽器訪問localhost:
再測試下我們的SSM工程裡測試類的正常工作截圖:
控制檯的輸出和日誌資訊:
該有的輸出都是正常的,再看一下我們儲存到本地的日誌檔案:
成功地儲存了我們工程的輸出日誌。
一晚上堅持一口氣寫完整個日誌,到這裡終於完美地結束了,如果大家覺得在下寫的記錄有幫助,可以給下支援和訂閱哦!
