创建自己的任务(AdUpdateJob):
配置自己写的定时任务:
前言:
在分布式项目中,实际开发会采用负载均衡策略,那么一个服务也许会部署多个服务器。如果说不采用任务调度中心而是在服务模块中写定时任务的话,会造成同一个任务多次执行,有可能会造成数据库的多次修改。
xxl-job配置与启动:
xxl-job-admin:
分布式任务调度平台XXL-JOB (xuxueli.com),从该网址clone代码。
改成自己的数据库,同时还需要创建数据库和执行sql文件
xxl-job-execultor--sample-springboot:
上面的注解用来表示该任务的名称。
如果以后想要添加自己的定时任务,只需要在这个模块里面写就行了
启动任务调度中心:
启动的url是 localhost:xxl-job-admin的端口号/jobinfo
我的是 localhost:8069/jobinfo
调用定时任务:
虽然我们成功跑起来了,但是大伙还是有很多疑惑,比如怎么配置自己的定时任务,以及如何在自己的项目中使用定时任务,接下来才是重点
在自己的项目中配置xxl-job:
项目结构:
AdUpdateTaskConfig:

### xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
xxl.job.admin.addresses=http://127.0.0.1:8069/xxl-job-admin
### xxl-job, access token
xxl.job.accessToken=default_token
### xxl-job executor appname
xxl.job.executor.appname=xxl-job-executor-sample
### xxl-job executor registry-address: default use address to registry , otherwise use ip:port if address is null
xxl.job.executor.address=
### xxl-job executor server-info
xxl.job.executor.ip=
xxl.job.executor.port=9999
### xxl-job executor log-path
xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
### xxl-job executor log-retention-days
xxl.job.executor.logretentiondays=30
端口记得跟自己的xxl-job-admin服务端口对应

该依赖中我们引入了
<!-- xxl-job-core --> <dependency> <groupId>com.xuxueli</groupId> <artifactId>xxl-job-core</artifactId> <version>2.4.1-SNAPSHOT</version> </dependency>我们想要引入该依赖需要如下操作
导入xxl-job-core依赖到我们的项目中
创建自己的任务(AdUpdateJob):
package com.dmdd.taskservice.config;
import com.xxl.job.core.handler.annotation.XxlJob;
import lombok.extern.slf4j.Slf4j;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
@Slf4j
@Component
public class AdUpdateJob {
private static Logger logger = LoggerFactory.getLogger(AdUpdateJob.class);
@XxlJob("test")
public void updateAd() {
log.info("任务调度成功");
}
}
该任务的名字叫test。我们想要在自己的项目中调用该服务还是需要启动xxl-job-admin服务
配置自己写的定时任务:
点击新增
cron用来配置任务执行的时间
JobHandler要写任务名
配置完就可以启动了
