Spring Cloud 的@RefreshScope 导致控制器映射与自身发生冲突
Spring Cloud's @RefreshScope causes controller mapping collision with itself
我正在尝试按照 this link 上的教程来测试 Spring Cloud，但是每当我使用 @RefreshScope 连接我的控制器时，我都会收到一个错误 RequestMapping 已被占用。如果我删除 @RefreshScope 一切正常，我会看到来自配置服务器的值。
如有任何帮助，我们将不胜感激。谢谢！
代码：
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
public class WebCloudPoc {
public static void main(String[] args){
SpringApplication.run(WebCloudPoc.class, args);
}
@RestController
@RefreshScope
public static class ProjectNameRestController {
@Value("${configuration.projectName}")
private String projectName;
@RequestMapping("/project-name")
public String projectName() {
return this.projectName;
}
}
}
日志输出如下：

Disconnected from the target VM, address: '127.0.0.1:55585', transport: 'socket'
@David Welch，我认为这与 @Configuration classes（@SpringBootApplication 是）处理静态内部 classes 的方式有关。我 moved 控制器到顶层 class 并且它全部编译并且 运行 很好。
我正在尝试按照 this link 上的教程来测试 Spring Cloud，但是每当我使用 @RefreshScope 连接我的控制器时，我都会收到一个错误 RequestMapping 已被占用。如果我删除 @RefreshScope 一切正常，我会看到来自配置服务器的值。
如有任何帮助，我们将不胜感激。谢谢！
代码：
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
public class WebCloudPoc {
public static void main(String[] args){
SpringApplication.run(WebCloudPoc.class, args);
}
@RestController
@RefreshScope
public static class ProjectNameRestController {
@Value("${configuration.projectName}")
private String projectName;
@RequestMapping("/project-name")
public String projectName() {
return this.projectName;
}
}
}
日志输出如下：
