Node.js JHIPSTER注册表和NODEJS eureka js客户端NullPointerException

我想在jhipster注册表上添加一个node.js服务器作为微服务应用程序。 我使用eureka js客户端npm包

您可以在github上找到一个节点测试项目“zhudan/node eureka”

// ------------------ Eureka Config --------------------------------------------
var Eureka = require("eureka-js-client").Eureka;

var client = new Eureka({
    filename: 'eureka-client',
    cwd: __dirname
});
client.logger.level('debug');
client.start(function(error){
    console.log(error || 'complete');
});


// ------------------ Server Config --------------------------------------------
var server = app.listen(9999, function () {
    var host = server.address().address;
    var port = server.address().port;
    console.log('Listening at http://%s:%s', host, port);
});

我更改了eureka-client.yml以便与jhipster注册中心合作

eureka:
  heartbeatInterval: 10
  maxRetries: 10
  requestRetryDelay: 60
  registryFetchInterval: 10
  host: 'admin:admin@localhost'
  port: 8761
  servicePath: '/eureka/apps'

instance:
  instanceId: "node-euraka"
  app: 'node-eureka'
  hostName: '127.0.0.1'
  #ipAddr: '192.168.10.145'
  statusPageUrl: 'http://127.0.0.1:9999'
  port:
      '$': 9999
      '@enabled': 'true'
  vipAddress: 'node-eureka'
  dataCenterInfo:
      '@class': 'com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo'
      name: 'MyOwn'

它工作得很好我有一个完整的注册和心跳工作得很好

$ node app
Listening at http://:::9999
registered with eureka:  node-eureka/node-euraka
retrieved registry successfully
complete
eureka heartbeat success
retrieved registry successfully
eureka heartbeat success
retrieved registry successfully
eureka heartbeat success
retrieved registry successfully

但是在jhipster注册表上，我得到了一个nullpointerexception

每次刷新应用程序的JHipster注册表视图时，我都会获得一个nullpointerexception

PS:JHipster注册表以./mvnw命令开始，而您的git repo没有任何更改

我向您提供jhipster注册中心的完整日志

关于，

您是否尝试在调试器下运行注册表，以查看节点应用程序注册的问题，并与jhipster服务进行比较？这里的断点也应该有帮助，您在instanceId中有一个输入错误：“node euraka”。可能并不重要
