xxl job踩坑记

先来点套话凑字数：

原因：版本号不一致。。。
解决：请换个版本

原因：版本号不一致导致的js之类的前端缓存未清理
解决：换个浏览器或者Ctrl+F5强制刷新

其他问题一般只要对照这三个步骤即可判断：

在源码中，作者提供了各个版本的 执行器项目，此处以xxl-job-executor-sample-springboot项目为例。也可以自己创建项目，然后按照demo或文档进行改造。

　　com.xuxueli
   xxl-job-core
   ${project.parent.version}

#日志文件
# log config
logging.config=classpath:logback.xml

#调度中心部署跟地址：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"。
### xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
xxl.job.admin.addresses=http://127.0.0.1:8080/xxl-job-admin

#执行器的名称、ip地址、端口号
### xxl-job executor address
xxl.job.executor.appname=xxl-job-executor-sample
xxl.job.executor.ip=
xxl.job.executor.port=9999

#执行器通讯TOKEN：非空时启用
### xxl-job, access token
xxl.job.accessToken=

#执行器运行日志文件存储的磁盘位置，需要对该路径拥有读写权限
### xxl-job log path
xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
#执行器Log文件定期清理功能，指定日志保存天数，日志文件过期自动删除。限制至少保持3天，否则功能不生效
#-1表示永不删除
### xxl-job log retention days
xxl.job.executor.logretentiondays=-1

##yml格式 有说不能用域名或127.0.0.1的，但我没测出来为什么不能用
xxl:
  job:
    enabled: true
    accessToken:
    admin:
      addresses: http://127.0.0.1:9102/xxl-job-admin
    executor:
      appname: hospital-ninth-xxljob
      ip: 127.0.0.1
      logpath: /opt/project/xxl-job/log
      logretentiondays: 30
      port: 9999

注意：配置执行器的名称、IP地址、端口号，后面如果配置多个执行器时，要防止端口冲突

package com.xxl.job.executor.core.config;

import com.xxl.job.core.executor.impl.XxlJobSpringExecutor;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class XxlJobConfig {
    private Logger logger = LoggerFactory.getLogger(XxlJobConfig.class);

    @Value("${xxl.job.admin.addresses}")
    private String adminAddresses;

    @Value("${xxl.job.executor.appname}")
    private String appName;

    @Value("${xxl.job.executor.ip}")
    private String ip;

    @Value("${xxl.job.executor.port}")
    private int port;

    @Value("${xxl.job.accessToken}")
    private String accessToken;

    @Value("${xxl.job.executor.logpath}")
    private String logPath;

    @Value("${xxl.job.executor.logretentiondays}")
    private int logRetentionDays;

    @Bean(initMethod = "start", destroyMethod = "destroy")
    public XxlJobSpringExecutor xxlJobExecutor() {
        logger.info(">>>>>>>>>>> xxl-job config init.");
        XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
        xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
        xxlJobSpringExecutor.setAppName(appName);
        xxlJobSpringExecutor.setIp(ip);
        xxlJobSpringExecutor.setPort(port);
        xxlJobSpringExecutor.setAccessToken(accessToken);
        xxlJobSpringExecutor.setLogPath(logPath);
        xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);

        return xxlJobSpringExecutor;
    }

    

}
