@RefreshScope和/refresh无法正常工作 [英] @RefreshScope and /refresh not working

问题描述

我尝试使用Config Server实施spring外部配置.第一次启动应用程序时，它运行良好，但是对属性文件的任何更改均未反映出来.我尝试使用/refresh端点动态刷新我的属性，但似乎无法正常工作.在这方面的任何帮助将大有帮助.

I have tried to implement spring external configurations using Config Server. It is working fine for the very first time when the application is started but any changes to the properties file are not being reflected. I tried to use /refresh endpoint to refresh my properties on the fly but it doesn't seem to be working. Any help on this would be greatly helpful.

我尝试过POST到localhost:8080/refresh，但收到404错误响应.

I tried POSTing to localhost:8080/refresh but getting a 404 Error response.

下面是我的应用程序类的代码

Below is the code of my application class

   @SpringBootApplication
public class Config1Application {

    public static void main(String[] args) {
        SpringApplication.run(Config1Application.class, args);
    }
}

@RestController
@RefreshScope
class MessageRestController {

    @Value("${message:Hello default}")
    private String message;

    @RequestMapping("/message")
    String getMessage() {
        return this.message;
    }
}

并且POM文件是

和bootstrap.properties

and bootstrap.properties

spring.application.name=xxx
spring.cloud.config.uri=https://xxxxxx.com
management.security.enabled=false
endpoints.actuator.enabled=true

推荐答案

对于Spring 2和更高版本，端点现在为/actuator/refresh

The endpoint is now /actuator/refresh for Spring 2 and greater

来自评论:

• 您确实需要在bootstrap.properties/bootstrap.yml
中设置management.endpoints.web.exposure.include=refresh

注意:如果您是Spring-Cloud的新手，并且不确定web.exposure中所有关键字的含义，可以将其设置为*(management.endpoints.web.exposure.include=*)所有这些都暴露了，您以后可以了解端点及其限制.

Note: If you're new to Spring-Cloud and not quite sure of what all keywords can go in web.exposure you can set it to * (management.endpoints.web.exposure.include=*) to have all exposed and you can get to know the endpoints and their restrictions later.
