問題描述

在springboot項目里配置了xxl-job2.3.0，但是執(zhí)行器無法自動注冊
yaml配置如下：

xxl:
  job:
    admin:
      enable: true
      address: http://192.xxx.xxx.xxx:38080/xxl-job-admin
      password: admin
      username: 123456
    accessToken:
    executor:
      appname: test-executor
      address:
      ip:
      port: 9993
      logpath: /data/applogs/xxl_job/jobHandler
      logretentiondays: 7

執(zhí)行器無法自動注冊到xxl-job-admin

排查過程

經過debug發(fā)現，是spring沒有加載xxlJobExecutor這個Bean
debug流程（SpringApplication.run()–>SpringApplication.refreshContext()–>SpringApplication.refresh() -->SpringApplication.finishBeanFactoryInitialization(ConfigurableListableBeanFactory beanFactory)）

解決方法

自己配置個xxlJobExecutor Bean

@Configuration
@Slf4j
public class XxlJobConfig {

    @Value("${xxl.job.admin.address}")
    private String adminAddress;

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

    @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.executor.logpath}")
    private String logPath;

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

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


    @Bean
    public XxlJobSpringExecutor xxlJobExecutor() {
        log.info(">>>>>>>>>>> xxl-job config init.");
        XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
        xxlJobSpringExecutor.setAdminAddresses(adminAddress);
        xxlJobSpringExecutor.setAppname(appName);
        xxlJobSpringExecutor.setAddress(address);
        xxlJobSpringExecutor.setIp(ip);
        xxlJobSpringExecutor.setPort(port);
        xxlJobSpringExecutor.setAccessToken(token);
        xxlJobSpringExecutor.setLogPath(logPath);
        xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);

        return xxlJobSpringExecutor;
    }
}

配置完成后，再次debug啟動服務，可以看到beanFactory里有xxlJobExecutor Bean，執(zhí)行器也注冊到了xxl-job-admin
