@RefreshScope and /refresh not working

问题

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.

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

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;
    }
}

and POM file is

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.0.RELEASE</version>

and bootstrap.properties

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

回答1:

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

From the comments:

You do need to have the management.endpoints.web.exposure.include=refresh set in the bootstrap.properties/bootstrap.yml

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.

回答2:

It worked for me after adding the property "management.endpoints.web.exposure.include=*" in bootstrap.properties and changing the url to /actuator/refresh for spring version above 2.0.0 For spring version 1.0.5 url is /refresh

回答3:

If you have issues with accepting formurlencoded in SPRING 2.0>, use :

curl -H "Content-Type: application/json" -d {} http://localhost:port/actuator/refresh

instead of:

curl -d {} http://localhost:port/refresh

which was accepted in SPRING 1.*
