Springboot 整合 xxljob 动态API调度任务(进阶篇)

# 前言 #

之前写了一篇 xxljob的新手入门篇：

[Springboot 整合 xxljob 使用定时任务调度(新手入门篇)\_小目标青年的博客-CSDN博客][Springboot _ xxljob _-CSDN]

这一篇非常非常简单，就是非常快速的springboot整合 xxljob，相当于拿来即用，能够通过页面配合代码去实现定时任务的使用。

这一篇，我们将在上一篇的基础上，做一些进阶使用，实现动态地调度定时任务。

我们平时工作经常会遇到这些业务使用场景（举例）：  
  
执行某个业务后，需要产生一个定时任务；

怎么怎么判断成功后，需要停止某个任务；

怎么怎么判断符合条件后，需要重新执行某个任务；

怎么怎么....移除某个任务；

摊牌了，实现的效果就是：  
  
**通过API方式（或者方法函数），我们动态随意地去 增删改查、设置定时规则等等去调度任务。**

上一篇几乎是基于HTML页面去对任务创建、启动、停在、删除等等， 非常需要有人去处理，这一篇就是解放我们双手！

# 正文 #

惯例，瞎话一张简图：

大致就是admin上面写一些开放接口，各个接入xxl job的demo服务都能通过接口调用，完成动态调度，至于啥时候调度，看自己的业务场景，自己使用。

① admin 服务 加接口，其实说实话，原先也提供了很多api接口，但是我这次非得自己搞一下。

XxlJobQuery.java

（这里有说法，为什么我这篇特意写了一个这个查询类，抛砖引玉，在新手篇里面我介绍过，xxl job 是有数据库的，意味着我们可以很容易拓展）

/**
     * @Author: JCccc
     * @Date: 2022-6-2 14:23
     * @Description: xxl job rest api
     */
    public class XxlJobQuery {
    
    	private	int start;
    	private int length;
    	private int triggerStatus;
    	private String jobDesc;
    	private String executorHandler;
    	private String author;
    	private int jobGroup;
    
    	public int getStart() {
    		return start;
    	}
    
    	public void setStart(int start) {
    		this.start = start;
    	}
    
    	public int getLength() {
    		return length;
    	}
    
    	public void setLength(int length) {
    		this.length = length;
    	}
    
    	public int getTriggerStatus() {
    		return triggerStatus;
    	}
    
    	public void setTriggerStatus(int triggerStatus) {
    		this.triggerStatus = triggerStatus;
    	}
    
    	public String getJobDesc() {
    		return jobDesc;
    	}
    
    	public void setJobDesc(String jobDesc) {
    		this.jobDesc = jobDesc;
    	}
    
    	public String getExecutorHandler() {
    		return executorHandler;
    	}
    
    	public void setExecutorHandler(String executorHandler) {
    		this.executorHandler = executorHandler;
    	}
    
    	public String getAuthor() {
    		return author;
    	}
    
    	public void setAuthor(String author) {
    		this.author = author;
    	}
    
    	public int getJobGroup() {
    		return jobGroup;
    	}
    
    	public void setJobGroup(int jobGroup) {
    		this.jobGroup = jobGroup;
    	}
    }

② 在接入xxl job 的demo上 开始玩动态调度，其实就是调用admin里我们刚才写的提供的接口

> PS： 本篇里面有些不好的编码习惯，例如返回值用Map；打印用的输出，没用log； 接口返回没有统一返回数据等等， 因为我该篇是为了传递 怎么动态调度使用，具体细节大家自行调整就行，我们都是成年人，不要在意我这些点。

先是pom.xml 引入使用的一些jar：

（一个是fastjson，大家别学我，我是为了实战示例图方便，用的JsonObject来传参）

（一个是httpClient ，用于调用admin服务的api接口）

XxlJobInfo.java

这个是原作者的其实，因为我们本质还是调用了作者xxl job提供的 XxlJobService 里面的方法。

#       开始验证测试 #

##       创建任务： ##

##  ##

### 打开admin的HTML页面，这是原来上次我们手动创建的任务：   ![acbacbd450484b199b201714a00f23ca.png][] ###

现在我们通过api调用创建一个新的任务：  
![4654d1c292e5409eb7fb294eafb3c66b.png][]

调用接口后，可以看的任务创建出来了，按照我们的cron和其他调度规则开始跑了：

![099e2be9aab444d08f91988392d7c9e3.png][]

![614b1d436b3f4ba8bae100cf4c605fea.png][]

然后我们调用停止任务接口（通过任务ID停止）：  
![d20f06dbc633422e8ce35b22551a27ed.png][]

![454eb25d617d4fcf84ceed7d6dcf1fa7.png][]

停在成功：

![567b50b4b3b54209a89dcd6a454d0e82.png][]

那么玩到这，可能大伙会有疑问，我怎么知道哪个我要停止的任务的任务ID是哪个？

所以我抛砖引玉写了个查询列表接口，大家可以意会一下，数据都在的，数据还不好拓展么，什么业务场景，怎么使用怎么调度，都可以自由发挥啊：  
![856f83fbd12b40e68985a4a66ddf660a.png][]

数据就在库里，自己查不就好了：  
![949b68aad8564c858ac945f22594419f.png][]

剩下还有启动 start接口，删除delete接口，修改update接口，我就不一一展示测试了。

这些增删改查，怎么组合使用，什么业务使用，大家自己玩起来就行。

好吧，该篇就到这。
