Nacos keep making requests.

Sunw730 commented 4 years ago

Describe the bug Hello, I used nacos in my project, but when I modified extension-configs configuration, I found a strange problem:

configuration one: dataId=db-demo.yml&group=COMPONENT

spring:
application:
name: stark.demo
cloud:
nacos:
  config:
    extension-configs:
      - dataId: db-demo.yml
        group: COMPONENT
        refresh: true
    group: COMPONENT

configuration two: dataId=db.demo.yml&group=DEFAULT_GROUP

spring:
application:
name: stark.demo
cloud:
nacos:
  config:
    extension-configs:
      - dataId: db.demo.yml
        group: DEFAULT_GROUP
        refresh: true
    group: COMPONENT

configuration three: dataId=db.demo.yml&group=COMPONENT

spring:
application:
name: stark.demo
cloud:
nacos:
  config:
    extension-configs:
      - dataId: db.demo.yml
        group: COMPONENT
        refresh: true
    group: COMPONENT

Here are three configurations for testing.

The test result are:

The project is running normally when configuration 1 or configuration 2 are uesd, but with configuration 3, the console prints nacos requests all the time.

I noticed that with configuration 3, the console gets an extra log:

Describe the bug Hello, I used nacos in my project, but when I modified extension-configs configuration, I found a strange problem:

configuration one: dataId=db-demo.yml&group=COMPONENT

spring:
  application:
    name: stark.demo
  cloud:
    nacos:
      config:
        extension-configs:
          - dataId: db-demo.yml
            group: COMPONENT
            refresh: true
        group: COMPONENT

configuration two: dataId=db.demo.yml&group=DEFAULT_GROUP

spring:
  application:
    name: stark.demo
  cloud:
    nacos:
      config:
        extension-configs:
          - dataId: db.demo.yml
            group: DEFAULT_GROUP
            refresh: true
        group: COMPONENT

configuration three: dataId=db.demo.yml&group=COMPONENT

spring:
  application:
    name: stark.demo
  cloud:
    nacos:
      config:
        extension-configs:
          - dataId: db.demo.yml
            group: COMPONENT
            refresh: true
        group: COMPONENT

Here are three configurations for testing.

The test result are:

The project is running normally when configuration 1 or configuration 2 are uesd, but with configuration 3, the console prints nacos requests all the time.

.....

I noticed that with configuration 3, the console gets an extra log:

2020-07-28 16:09:43.251  INFO 29065 --- [           main] c.a.nacos.client.config.utils.JVMUtil    : isMultiInstance:false

nacos version:

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
    <version>2.2.1.RELEASE</version>
</dependency>

I made a mistake. The configuration 1 and configuration 2 both have the same problems. The reason why they were not found before is that there is no corresponding configuration in nacos

Sunw730 commented 4 years ago

which version of service you used?

nacos/nacos-server:latest

KomachiSion commented 4 years ago

So, Have the problem solved?

Sunw730 commented 4 years ago

So, Have the problem solved?

The problem is still there, but it can be fixed with switching another namespace, which only happens in namespace public.

KomachiSion commented 4 years ago

I think it may be the configuration problem, not namespace problem.

@chuntaojun @TsingLiang Can you help to check the configuration whether right?

chuntaojun commented 4 years ago

nacos-server version？

贴出你全部的bootstrap 配置信息，不要只给一部分

贴出你全部的bootstrap 配置信息，不要只给一部分

不好意思，最近比较忙，没来得及回复您。

我再详细描述一下，并贴上我的全部代码，我是新创建的一个springcloud的项目，里面只有一个启动类，然后bootstrap.yml的所有配置是：

spring:
  cloud:
    nacos:
      config:
        server-addr: localhost:8848
        namespace: public
        extension-configs:
          - dataId: nacos-demo-ext.yml
            group: DEFAULT_GROUP
            refresh: true

application.yml的配置是：

spring:
  application:
    name: nacos-demo

在nacos中有两个namespace：public（默认的）和myspace（自己创建的），每个namespace下都创建了两个配置文件nacos-demo.yml和nacos-demo-ext.yml，他们都用的默认group(DEFAULT_GROUP)，里面的内容无关紧要，你可以随便配置。

nacos服务是我本地使用docker启动的，版本为latest，我的jdk是zulu openjdk11，当然，oracle jdk1.8我也试过，有相同的问题。

当使用namespace=public，启动完成后，控制台一直打印输出nacos请求日志，日志内容见上面的描述。当使用namespace=myspace，服务则一切正常。

我的测试代码也放到github了，你们也可以看看，只需把nacos的server-addr修改一下，然后启动一下就能看到问题了。只有public命名空间有这个问题。

测试代码：https://github.com/Sunw730/nacos-demo

chuntaojun commented 4 years ago

默认的命名空间不要去设置namespace

Sunw730 commented 4 years ago

默认的命名空间不要去设置namespace

测试了一下这样的确是可行的，不知道这个是什么原因呢？

不过这个问题建议修复一下，好的产品不应该通过”避免配置“来解决这个问题
