XXL 的JobSpringExecutor自动获取IP不对

1.配置

xxl.job.admin.addresses=http://192.168.31.53:8080/xxl-job-admin

### xxl-job executor address

xxl.job.executor.appName=carp-business-job-executor

### xxl.job.executor.ip=192.168.31.118

xxl.job.executor.port=9988

### xxl-job, access token

xxl.job.accessToken=

### xxl-job log path

xxl.job.executor.logPath=/data/applogs/xxl-job/jobhandler

### xxl-job log retention days

xxl.job.executor.logRetentionDays=30

 

2.config

@Configuration
@Slf4j
public class XxlJobConfig {

    @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 String 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
    public XxlJobSpringExecutor xxlJobExecutor() {
        log.info(">>>>>>>>>>> xrj xxl-job config init.");
        XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
        xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
        xxlJobSpringExecutor.setAppName(appName);
        String ip= null;
        try {
            ip= IpUtil.getLocalHostLANAddress().getHostAddress();
        } catch (UnknownHostException e) {
            log.error("UnknownHostException ",e);
        }
        log.info("XxlJobSpringExecutor ip:"+ip);
        xxlJobSpringExecutor.setIp(ip);
        int nowPort;
        try {
            nowPort = Integer.parseInt(port);
        } catch (Exception e) {
            nowPort = 9999;
        }
        xxlJobSpringExecutor.setPort(nowPort);
        xxlJobSpringExecutor.setAccessToken(accessToken);
        xxlJobSpringExecutor.setLogPath(logPath);
        xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);

        return xxlJobSpringExecutor;
    }



}
