idea搭建简单ssm框架的最详细教程（新）

为开发一个测试程序，特搭建一个简单的ssm框架，因为网上看到很多都是比较老旧的教程，很多包都不能用了，eclipes搭建并且其中还附带了很多的其他东西，所以特此记录一下mac中idea搭建过程。

 

另：平常开发的项目中其实用的不是mybatis，而是mybatisplus，一款为简化开发而生的基于mybatis的三方，只能说，用起来贼爽，省去了很多的sql语句。

 

以下为一步步操作，详细可循，完全学习了白居易写诗的风格，堪称傻瓜教程。

 

目录结构已建好的童鞋，可以直接跳过前几步去看相应配置文件，点击穿越 

一、搭建背景及准备条件

不是必须的，保证项目运行只要有这些东西就行，可以不一样

mac下idea，maven3.6.0，jdk1.8，tomcat8，mysql5.7

 

二、搭建开始——新建项目

1. file -> new -> project

 

2. 新建maven项目，如图勾选 create from archetype，并选择 maven-archetype-webapp，next

 

3. 输入坐标及项目名，next

 

4. 选择maven配置，选择你自己的maven，next

 

5. 确定项目名，finish

 

6. 成功后的项目结构

 

三、完善项目结构

1. 新建java目录  src/main/java

 

2. 新建资源目录  resources

 

 

3. 新建webapp目录  webapp，同样的方法，不过idea会自动创建里边的WEB-INF等文件

 

 

4. 现在基本目录结构已建成，让我们对比一下看是不是一样的，见证奇迹

 

5. 将响应目录 右键 设置为对应属性  java标记为Soures Root　　resources标记为Resources Root

 

6. 设置为web项目，标记webapp为 web　　　　file -> Project Structure -> Models

 

 7. 在上图标记的 1，2 处 编辑修改路径 为 自己webapp的路径

 

8. 此时目录结构已经完善完成，移步下图

 

四、初步配置启动tomcat服务

1.  导入项目包 test2:war exploded　　file -> Project Structure -> Models

　选择你的项目，点击右下角 open

　选择maven，一路next下去，最后点击神圣的finish按钮，OK。（可能无此步骤，没有则忽略）

 

2. 还是刚才的界面，选择 Artifacts  此时第一次是会默认有两个包，如果没有则进行此步操作　file -> Project Structure -> Artifacts　

选择，点击右下 OK按钮

最终想要得到的结果如下图：

 

3. 进行了上述每一步操作后，很关键的要保存，点击apply 或者ok，apply按钮是不可点击状态才能关闭此面板哦，不然刚才所有操作都白费了

 

4. 添加tomcat，进行相关配置      点击面板右上角

添加配置tomcat

添加刚才生成的包

最后点击，apply，ok，好了完事了，准备运行吧

 

5. 运行tomcat   右上角面板选择debug模式运行（也可以普通模式）

运行成功，页面显示默认生成的index.jsp的内容　　http://localhost:8085/

 

五、配置spring容器等相关配置文件

 1. 在poom.xml（位置：项目的根目录下）中引入必要的poom依赖（其中包括了spring、springmvc、jdbc、mysql、druid连接池、mybatis、lombok插件、juni他、其他工具包 ）

如果想要自己添加jar包，可以在WEB-INF中新建lib文件夹，然后放入你的jar包（poom依赖下载的jar包编译过后其实也就是在编译包下的lib文件夹中）

每次更改poom依赖后，记得更新jar包，一般右下角都会弹出更新提示

 

2. 配置web.xml文件（位置：webapp下的WEB-INF中）　　tomcat启动时，会加载此文件，从而扫描加载其他的配置文件

其中包括了编码过滤、监听器、springmvc配置、spring容器中其他配置包括mybatis等、log4j配置、项目访问默认欢迎页，如需添加自定义过滤器，也许在此配置

 

3. 新建其他配置文件（位置：resoures下） applicationContext.xml、springmvc.xml、mybatis.xml、jdbc.properties、日志配置（log4j.properties和log4j.xml二选一，我用的log4j.xml）

好了，经过以上一套噼里啪啦的操作，配置基本算是好了，接下来让我们写代码检验一下我们的配置到底对不对呢，激动人心的时刻就要来了

 

六、编写代码测试

1. java文件夹下，新建package包com.test，另外再新建包括controller、mapper、model、service的四个包

　新建完结构如图所示

 

2. 在每个包下分别新建代码文件：TestController.java、TpmTestLogService.java、TpmTestLogServiceImpl.java、TpmTestLogMapper.java、TpmTestLogMapper.xml、TpmTestLog

　

　实体类：TpmTestLog.java

package com.test.model;

import lombok.Data;

import java.io.Serializable;

/**
 * @TpmTestLog
 * @(TPM_TEST_LOG)
 * @version : Ver 1.0
 */
@Data
public class TpmTestLog implements Serializable {


    /**
     * @备注: 主键
     * @字段:LOG_UUID bigint
     */
    private Long logUuid;


    /**
     * @备注:
     * @字段:TESTMAIN_UUID CHAR(32)
     */
    private String testmainUuid;


    /**
     * @备注:
     * @字段:OPERATION VARCHAR(20)
     */
    private String operation;


    /**
     * @备注:
     * @字段:SYSCREATEDATE VARCHAR(25)
     */
    private String syscreatedate;




}

View Code

　

　数据库交互层dao接口：TpmTestLogMapper.java

package com.test.mapper;

import com.test.model.TpmTestLog;

/**
 * @TpmTestLogMapper
 * @Mapper
 * @version : Ver 1.0
 */
public interface TpmTestLogMapper {

    Long insert(TpmTestLog tpmTestLog);

}

View Code

　对应的xml：TpmTestLogMapper.xml

    
    

    
        LOG_UUID AS logUuid,
        TESTMAIN_UUID AS testmainUuid,
        OPERATION AS operation,
        SYSCREATEDATE AS syscreatedate
    

    
      INSERT INTO TPM_TEST_LOG (LOG_UUID,
                                          TESTMAIN_UUID,
                                          OPERATION,
                                          SYSCREATEDATE)
              VALUES   (#{logUuid},
                          #{testmainUuid},
                          #{operation},
                          #{syscreatedate})
    

View Code

 

　业务层接口类sercice：TpmTestLogService.java

package com.test.service;

import com.test.model.TpmTestLog;

/**
 * @TpmTestLogService
 * @Service
 * @version : Ver 1.0
 */
public interface TpmTestLogService{

    Long ceshi(TpmTestLog tpmTestLog);
}

View Code

　业务层的实现类impl：TpmTestLogServiceImpl.java

package com.test.service.impl;

import com.test.mapper.TpmTestLogMapper;
import com.test.model.TpmTestLog;
import com.test.service.TpmTestLogService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

/**
 * @TpmTestLogServiceImpl
 * @ServiceImpl
 * @version : Ver 1.0
 */
@Service
@Transactional
public class TpmTestLogServiceImpl implements TpmTestLogService {

    @Autowired
    private TpmTestLogMapper tpmTestLogMapper;

    @Override
    public Long ceshi(TpmTestLog tpmTestLog) {
        return tpmTestLogMapper.insert(tpmTestLog);
    }
}

View Code

 

　接口逻辑层controller：TestController.java

package com.test.controller;

import com.alibaba.fastjson.JSONObject;
import com.test.model.TpmTestLog;
import com.test.service.TpmTestLogService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/api")
public class TestController {

    @Autowired
    private TpmTestLogService tpmTestLogService;

    @GetMapping("/test")
    public JSONObject test(){

        JSONObject jsonObject = new JSONObject();

        TpmTestLog tpmTestLog = new TpmTestLog();
        tpmTestLog.setSyscreatedate("asfasgags");
        tpmTestLog.setTestmainUuid("fdasgassfsarew");
        tpmTestLog.setOperation("新增");
        tpmTestLogService.ceshi(tpmTestLog);

        jsonObject.put("title", "测试成功" + tpmTestLog.getLogUuid());
        return jsonObject;
    }

}

View Code

 

3. 数据库交互，测试表以及数据库连接文件jdbc中的配置（文中5.3已有配置文件）  Table：TPM_TEST_LOG　　

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
--  Table structure for `TPM_TEST_LOG`
-- ----------------------------
DROP TABLE IF EXISTS `TPM_TEST_LOG`;
CREATE TABLE `TPM_TEST_LOG` (
  `LOG_UUID` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '主键',
  `TESTMAIN_UUID` varchar(32) COLLATE utf8_bin DEFAULT NULL,
  `OPERATION` varchar(20) COLLATE utf8_bin DEFAULT NULL,
  `SYSCREATEDATE` varchar(25) COLLATE utf8_bin DEFAULT NULL,
  PRIMARY KEY (`LOG_UUID`)
) ENGINE=InnoDB AUTO_INCREMENT=26 DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

SET FOREIGN_KEY_CHECKS = 1;

View Code

 

4. 测试接口  因为是写的测试是get请求，所以可以直接在浏览器中测试，地址栏输入接口地址（4.4中你配置的地址），回车访问，如下图

 

七、前端页面和接口交互测试

1. 编写前端页面测试代码（不要说你是后台，不会写前端代码，不会也没关系，直接copy吧，有问题找google）

 

　前边生成的index.jsp我们稍加改动

Hello World!

View Code

　由于页面中引用了万能的jquery语法，所以在webapp下新建js文件夹，并放入jquery文件，点击下载

　不要问为什么要用jquery，怎么不用原生js，因为我愿意。

　好吧，其实是为了代码的简洁高效，毕竟封装了很多方法，让我们可以更注重逻辑

　当然原生的也不是不能写，下面是原生的js方法，只需将此方法放入index.jsp里边的script标签中即可，如果没有引入jquery，记得注释掉原来的方法

window.onload = function () {

        //步骤一:创建异步对象
        var ajax = new XMLHttpRequest();
        //步骤二:设置请求的url参数,参数一是请求的类型,参数二是请求的url,可以带参数,动态的传递参数starName到服务端
        ajax.open('get', '/api/test');
        //步骤三:发送请求
        ajax.send();
        //步骤四:注册事件 onreadystatechange 状态改变就会调用
        ajax.onreadystatechange = function () {
            if (ajax.readyState == 4 && ajax.status == 200) {
                //步骤五 如果能够进到这个判断 说明 数据 完美的回来了,并且请求的页面是存在的
                console.log(ajax.responseText);//输入相应的内容
                console.log(JSON.parse(ajax.responseText).title);
                console.log(document.getElementsByTagName("h2")[0])
                document.getElementsByTagName("h2")[0].innerText = JSON.parse(ajax.responseText).title;
            }
        }
    }

View Code

 

2. 接下来见证奇迹，打开页面地址：http://localhost:8085/index.jsp

　后台经过与数据库交互后，把插入数据库后生成的主键4返回给前端，前端显示在页面中

 

 

　到这里这个简单的ssm框架就算搭建完成了，看起来过程很长，但实际操作起来应该是很快的，有问题欢迎留言，大家可以一起探讨！

 

　码字不易，且行且珍惜，如发现问题，欢迎指正，java深似海，小白在路上！

 

 

　mapper注入失败问题可以参考：https://www.cnblogs.com/mufengforward/p/11127088.html
