Spring Cloud Config Server并在整个Spring Boot应用程序上应用@RefreshScope

Question

I'm trying to refresh my properties, application-wide, on the fly, with Spring Cloud Config Server. I'm embedding my Config Server with my Spring Boot Client App and the app boots up perfectly.

When I try to update a property, for example: spring.datasource.url then I send a POST request to refresh the actuator : http://localhost:9190/management/refresh , I get the expected result :

[
   "spring.datasource.url"
]

I also created a controller for testing purposes :

@Value("${spring.datasource.url}")
private String message;

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

However, when I hit this controller on : http://localhost:9290/message I'm still getting the old unrefreshed value for ${spring.datasource.url} .

I have to explicitly add a @RefreshScope on my controller's class to get the updated value.

My question is : how can I achieve this application-wide ? or for each of these use cases ? :

• @Value s throughout my code,
• my jdbcTemplate that uses my datasource
• <context:property-placeholder> for my spring integration job
• logging with log4j

I'm using :

<spring-cloud.version>Edgware.SR1</spring-cloud.version>
<spring-boot-version>1.5.9.RELEASE</spring-boot-version>

@RefreshScope is needed to recreate the bean which in turn gets the updated value from the Spring Environment. The other option is to use @ConfigurationProperties beans which automatically are re-bound on /refresh without using @RefreshScope . There is no option to make all beans @RefreshScope automatically.
