spring 配置服务器不刷新属性

Question

我有一个 Spring Boot 应用程序，它使用配置服务器加载其属性。这些属性存在于配置服务器项目的 src.main/resources/config 目录中。

当我点击 restful 端点时，属性最初加载得很好，然后当我更改属性时，它仍然显示旧的属性值。我如何像调用 URL 一样调用刷新端点？我是在 config-service 还是 hello-service 上调用它？即使从日志中它看起来已经映射了它们，它仍然会抛出这个 405 错误

配置服务器

http://localhost:8889/refresh

或 hello-service

http://localhost:9001/refresh

我总是得到以下

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 的配置服务器中，我有以下文件

hello-service.properties

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

在我的问候服务中，我有以下内容

应用程序类

 @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;
    }

Controller 类

//    @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 的启动日志显示以下端点
