錯誤資訊
初看的時候還以為是端口占用:
Address already in use: bind
,不要被錯誤提示蒙蔽了,實則是
xxl-job
的執行器注解
@Bean
配置的問題。

問題定位
在低版本的
xxl-job
中, 初始化
XxlJobSpringExecutor
執行器需要在
@Bean
中加上
initMethod = "start", destroyMethod = "destroy"
,但是在高版本的
xxl-job
(如
2.1.2
)則需要删除
initMethod = "start", destroyMethod = "destroy"
報錯前
@Bean(initMethod = "start", destroyMethod = "destroy")
public XxlJobSpringExecutor xxlJobExecutor() {
log.info(">>>>>>>>>>> xxl-job config init.");
XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
xxlJobSpringExecutor.setAdminAddresses(jobProperties.getAdminAddresses());
xxlJobSpringExecutor.setAppName(jobProperties.getAppName());
xxlJobSpringExecutor.setPort(jobProperties.getPort());
xxlJobSpringExecutor.setLogPath(jobProperties.getLogPath());
xxlJobSpringExecutor.setLogRetentionDays(jobProperties.getLogRetentionDays());
xxlJobSpringExecutor.setIp(jobProperties.getIp());
xxlJobSpringExecutor.setAccessToken(jobProperties.getAccessToken());
return xxlJobSpringExecutor;
}
解決
把
@Bean
的屬性
initMethod = "start", destroyMethod = "destroy"
删除即可,代碼如下:
@Bean
public XxlJobSpringExecutor xxlJobExecutor() {
log.info(">>>>>>>>>>> xxl-job config init.");
XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
xxlJobSpringExecutor.setAdminAddresses(jobProperties.getAdminAddresses());
xxlJobSpringExecutor.setAppName(jobProperties.getAppName());
xxlJobSpringExecutor.setPort(jobProperties.getPort());
xxlJobSpringExecutor.setLogPath(jobProperties.getLogPath());
xxlJobSpringExecutor.setLogRetentionDays(jobProperties.getLogRetentionDays());
xxlJobSpringExecutor.setIp(jobProperties.getIp());
xxlJobSpringExecutor.setAccessToken(jobProperties.getAccessToken());
return xxlJobSpringExecutor;
}
