XXL-JOB接入trace链路

蓟雪峰
2023-12-01

一、背景

目前XXL-JOB使用自定义XxlJobHelper来做日志埋点,但是实际上很多内部框架的日志都未接入,此时定时任务出现错误,需要上执行器上查看日志信息,这时候无法查询到本次调度相关日志。

二、环境

<dependency>
	<groupId>com.xuxueli</groupId>
	<artifactId>xxl-job-core</artifactId>
	<version>2.3.0</version>
</dependency>

三、实现

为了后续方便接入链路,使用MDC传递logId

日志埋点工具类

拦截器

@Aspect
@Order(-1)
public class XxlJobInterceptor {

    @Around("@annotation(xxlJob)")
    public Object handle(ProceedingJoinPoint point, XxlJob xxlJob) throws Throwable{
        try{

        } finally{
            MDC.remove(TraceConstant.TRACE_ID_NAME);
        }
    }

}

配置属性类

@Getter
@Setter
@ConfigurationProperties(prefix = "teddy.boot.xxl.job")
public class XxlJobProperties {

    private String adminAddresses;

    private String accessToken;

    private Executor executor;

    @Getter
    @Setter
    public static class Executor {

        private String ip;

        private int port;

自动配置类

@Configuration
@EnableConfigurationProperties(XxlJobProperties.class)
public class XxlJobAutoConfiguration {

    private static Logger log = LoggerFactory.getLogger(XxlJobAutoConfiguration.class);

    @Bean
    @ConditionalOnMissingBean
