是否可以服务只消费其他服务，不需要启动提供者

Open clverhack opened this issue 3 years ago • 5 comments

如题：我的springboot 工程只想消费其他dubbo服务。但是不想启动自带的提供者。目前没找到是否可以禁用的方式。

这是我的工程配置： 下面日志启动了28080端口，实际我不想要它启用，我只需要消费服务就好 dubbo: enabled: true application: name: mst-dubbo-pay-consumer registry: id: yzlpay address: N/A register: false subscribe: true

如果确定是一个纯消费端，并且不想开启 dubbo 端口，可以设置

dubbo:
  application:
     register-consumer: false

如果确定是一个纯消费端，并且不想开启 dubbo 端口，可以设置

dubbo:
  application:
     register-consumer: false

我这里并不起作用，不论register-consumer设置成true还是false，都会启动一个服务监听20880端口

+1 好像不起作用。 dubbo 3.0.9 triple

@chickenlj 好像不起作用。 dubbo 3.0.9 triple. 启动了一个提供者 register-consumer: false 后， 消费方还是会消费到。 另外，尝试单独关闭 dubbo.provider.export=false

dubbo:
  provider:
    export: true

这个就不会暴露服务了，但是会有个数组越界的异常。

然后， 这参数和 register-consumer一起设置，就达到效果了，不报错，不暴露服务

能否剥离一个简单的 demo 我们来测试下是哪里的问题
