前置条件

调度中心

demo配置

        <dependency>
            <groupId>com.xuxueli</groupId>
            <artifactId>xxl-job-core</artifactId>
            <version>2.2.0</version>
        </dependency>
### 调度中心部署跟地址 [选填]:如调度中心集群部署存在多个地址则用逗号分隔。执行器将会使用该地址进行"执行器心跳注册"和"任务结果回调";为空则关闭自动注册;
xxl.job.admin.addresses=http://127.0.0.1:9081/xxl-job-admin
### 执行器通讯TOKEN [选填]:非空时启用;
xxl.job.accessToken=
### 执行器AppName [选填]:执行器心跳注册分组依据;为空则关闭自动注册
#xxl.job.executor.appname=xxl-job-executor-demo
xxl.job.executor.appname=app-demo
### 执行器注册 [选填]:优先使用该配置作为注册地址,为空时使用内嵌服务 ”IP:PORT“ 作为注册地址。从而更灵活的支持容器类型执行器动态IP和动态映射端口问题。
xxl.job.executor.address=
### 执行器IP [选填]:默认为空表示自动获取IP,多网卡时可手动设置指定IP,该IP不会绑定Host仅作为通讯实用;地址信息用于 "执行器注册" 和 "调度中心请求并触发任务";
xxl.job.executor.ip=
### 执行器端口号 [选填]:小于等于0则自动获取;默认端口为9999,单机部署多个执行器时,注意要配置不同执行器端口;
xxl.job.executor.port=9999
### 执行器运行日志文件存储磁盘路径 [选填] :需要对该路径拥有读写权限;为空则使用默认路径;
xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
### 执行器日志文件保存天数 [选填] : 过期日志自动清理, 限制值大于等于3时生效; 否则, 如-1, 关闭自动清理功能;
xxl.job.executor.logretentiondays=30
