xxl-job 报：java.net.BindException: Address already in use: bind

在低版本的 xxl-job 中， 初始化 XxlJobSpringExecutor 执行器需要在 @Bean 中加上 initMethod = "start", destroyMethod = "destroy"，但是在高版本的 xxl-job（如 2.1.2）则需要删除 initMethod = "start", destroyMethod = "destroy"

报错前
@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;
}

解决

把 @Bean 的属性 initMethod = "start", destroyMethod = "destroy" 删除即可，代码如下：

@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;
}
