首页 > 解决方案 > 在 Spring Cloud Bus 中 POST /actuator/bus-refresh 时出现“方法不允许”错误

问题描述

我正在使用 Spring Cloud Bus 和 RabbitMQ 向某些微服务广播配置更改,但是当我向http://localhost:8888/actuator/bus-refresh发出 POST 请求时,我收到一个错误“方法不允许”,如以下:

HTTP/1.1 405 
Allow: GET
Content-Type: application/json
Transfer-Encoding: chunked
Date: Thu, 26 Mar 2020 05:53:36 GMT
Connection: close

{
  "timestamp": "2020-03-26T05:53:36.872+0000",
  "status": 405,
  "error": "Method Not Allowed",
  "message": "Request method 'POST' not supported",
  "path": "/actuator/bus-refresh"
}

这是我的 application.yml 文件

server.port: 8888
spring.cloud.config.server.git.uri: E:/Work/git/microservices-poc-using-spring-cloud/config-repo
management:
  endpoints:
    web:
      exposure:
        include: bus-refresh,refresh

但是,当我更改曝光属性以允许所有端点时,我得到了成功响应,并且更改成功地广播到了我的微服务。

management:
  endpoints:
    web:
      exposure:
        include: "*"

并且响应成功。

HTTP/1.1 204 
Date: Thu, 26 Mar 2020 05:42:32 GMT
Connection: close

我的 pom.xml 很简单

而且只有一个java文件

@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConfigServerApplication.class, args);
    }

}

解决方案


将以下内容添加到 application.properties 为我解决了这个问题。

management.endpoints.web.exposure.include=*

或者具体来说,您可以为所需的端点添加支持

management.endpoints.web.exposure.include=busrefresh

请注意,在旧版本中它是“总线刷新”
