How to get HttpServletRequest from spring proxy object

问题

在拦截器类中，我想获取HttpServletRequest对象：

public class MyEndpointInterceptorAdapter extends EndpointInterceptorAdapter {

  @Autowired
  private HttpServletRequest httpServletRequest;

  // ...

}

实际上，我得到的是一个HttpServletRequest的代理对象。
（图片已省略）

我如何从这个代理的Spring对象中获取原始的HttpServletRequest对象？

更新1：

根据请求，以下是堆栈跟踪：
java.lang.ClassCastException: com.sun.proxy.$Proxy622 无法强制转换为 weblogic.servlet.internal.ServletRequestImpl
at weblogic.servlet.internal.ServletRequestImpl.getOriginalRequest(ServletRequestImpl.java:1654)
at weblogic.servlet.security.ServletAuthentication.runAs(ServletAuthentication.java:726)

What I actually get is a proxy object of HttpServletRequest.

How I can get the original HttpServletRequest object out of this proxy spring object?

**得分**: -1
从由Spring在@Autowired注释下返回的代理对象中获取答案时，您无法访问原始的HttpServletRequest对象。
您可以通过不同的路径从RequestContextHolder获取HttpServletRequest对象：
```java
HttpServletRequest httpServletRequest = 
((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();

这样可以获取到原始的HttpServletRequest对象。

英文:

Fund the answer, from the proxy object returned by spring on @Autowired, you dont have access to original HttpServletRequest object.

you can get the HttpServletRequest object, through a different path from: RequestContextHolder

HttpServletRequest httpServletRequest = 
((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();

This gives you the original HttpServletRequest.
