Spring Boot：在spring rest控制器类上有一个自定义注释，导致识别处理程序映射时出错

标签： spring spring-mvc spring-boot annotations

我在Spring启动时在rest控制器类的顶部使用一个名为@Toggle的自定义注释来拦截handlerType以阻止其余的调用。

见下面的代码片段：

@RestController
@Toggle(feature="feature.foo")
@RequestMapping("/foo")
public class FooController {
  @RequestMapping("")
  public Map hello() {
    return Collections.singletonMap("message", "hello foo!");
  }
}

但是，即使在调度程序servlet找到处理程序方法之前，我也无法访问失败的api。

但是，如果我对rest控制器类中的方法使用相同的@Toggle注释，则处理程序映射会找到要调用的正确方法。

@RequestMapping("/foo")
  @Toggle(feature = "feature.foo")
  public Map hello() {
    return Collections.singletonMap("message", "hello foo!");
  }

即使我在rest控制器上使用自定义注释，如何确保spring boot映射到正确的处理程序方法。
