springboot整合xxl-job详解(亲测可用)
springboot整合xxl-job详解--亲测可用
- xxl-job下载
- xxl-job-admin环境搭建
- springboot项目整合xxl-job
xxl-job下载
下载地址：https://github.com/xuxueli/xxl-job/releases
我的下载版本：
xxl-job目录结构
xxl-job-admin环境搭建
第一步:
将该sql脚本在本地执行
第二步：
application.properties文件修改：
logback.xml文件修改
第三步：
到目前为止，该项目已经配置完成，可以进行启动了。用户名和密码:admin 123456
访问地址http://localhost:8080/xxl-admin-job,该地址是你没有修改端口号，和项目访问名称，启动成功如下：
这样就可以了，说明现在已经有了自己xxl-job环境
springboot项目整合xxl-job
第一步：创建一个spring-boot项目，我们自己创建这样更加清晰，如果使用官网提供的只需要改动下application.properties和logback.xml就可以启动了，并且xxl-admin-admin搭建完成已经附带了一个执行管理器和任务管理器不利于整合到自己的项目中步骤。
在这里我就不进行springboot项目创建了我相信大家都会。

我这里用的jdk11,你们可以选择较低版本的springboot使用较低的jdk,springboot整合xxl-job只需要引用xxl-job-core这一个坐标就可以了
第二步：配置application.properties
#no web
#spring.main.web-environment=false
#log config
logging.config=classpath:logback.xml
###xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
xxl.job.admin.addresses=http://127.0.0.1:8090/xxl-job-admin
###xxl-job, access token
xxl.job.accessToken=
###xxl-job executor appname
xxl.job.executor.appname=demo-service-impl
###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=/users/zhaoyihang/soft/xxl-job-log/jobhandler
###xxl-job executor log-retention-days
xxl.job.executor.logretentiondays=30
第三步：logback.xml配置
logback.xml就从你在官网中下载的源码中那一份修改下就可以了，这里就不提供了
第四步：
增加这两个类
XxlJobConfig.java该类为配置类
package com.example.demoserviceimpl.config;
import com.xxl.job.core.executor.impl.XxlJobSpringExecutor;

/**
* XxlJob开发示例（Bean模式）
*
* 开发步骤：
* 1、在Spring Bean实例中，开发Job方法，方式格式要求为 "public ReturnT execute(String param)"
* 2、为Job方法添加注解 "@XxlJob(value="自定义jobhandler名称", init = "JobHandler初始化方法", destroy = "JobHandler销毁方法")"，注解value值对应的是调度中心新建任务的JobHandler属性的值。
* 3、执行日志：需要通过 "XxlJobLogger.log" 打印执行日志；

到现在你就可以启动项目了，马上就结束了。
第五步：进入到xxl-job-admin平台进行配置
执行器：选择你刚刚建立的执行器
任务描述：根据业务填写
路由策略：你可以根据需要选择，不懂的话去网上查查应该描述的比我明白，我的实际开发中都是这一个
cron:这个简单，根据你想要执行的时间选择
运行模式：我在工作用到都是bean
JobHandler：就是图中截图
其他参数随意
现在就可以了，配置完之后，就可以点那个蓝色按钮启动或者停止，然后去看日志是否成功，一种是我在项目中打印了一行日志
或者看
希望我的文档可以给你带来帮助，写的不好希望大家见谅
