spring 配置服務器不刷新屬性

Question

我有一個 Spring Boot 應用程序，它使用配置服務器加載其屬性。 這些屬性存在於配置服務器項目的 src.main/resources/config 目錄中。

當我點擊 restful 端點時，屬性最初加載得很好，然后當我更改屬性時，它仍然顯示舊的屬性值。 我如何像調用 URL 一樣調用刷新端點？ 我是在 config-service 還是 hello-service 上調用它？ 即使從日志中它看起來已經映射了它們，它仍然會拋出這個 405 錯誤

配置服務器

http://localhost:8889/refresh

或 hello-service

http://localhost:9001/refresh

我總是得到以下

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Method Not Allowed, status=405).
Request method 'GET' not supported

在 src/main/resources/config 的配置服務器中，我有以下文件

hello-service.properties

#very-so-much=testing
very-so-much=testing second time
second-time=checking again

在我的問候服務中，我有以下內容

應用程序類

 @Bean
    @RefreshScope
    CustomerProps customerProps( @Value("${very-so-much}") String exclamations, @Value("${second-time}") String test) {
        CustomerProps p = new CustomerProps();
        //p.setText(exclamations);
        p.setText(test);
        return p;
    }

控制器類

//    @Value("${very-so-much}")
//    private String prop;
//    
//    @Value("${second-time}")
//    private String anotheerProp;

    @Autowired
    public GreetingController(CustomerRepository repository, GridFsTemplate gridFileSystem, CustomerProps props) {
        this.repository = repository;
        this.fs = gridFileSystem;
        this.props = props;
    }

    @RequestMapping("/greeting")
    public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
        name = props.getText();
        return new Greeting(counter.incrementAndGet(),
                            String.format(template, name));
    }

config-server 的啟動日志顯示以下端點
