Review Comment:
   The JavaDoc for the constructor is missing the `@param env` documentation. 
Please add:
   ```java
   /**
    * Instantiates a new context refreshed event listener.
    *
    * @param clientConfig                   the shenyu client config

Review Comment:
   The substring operation should verify that `decoratedPath` actually starts 
with `contextPath` before performing the substring. Without this check, if 
`decoratedPath` is longer than `contextPath` but doesn't start with it, the 
substring operation could produce an incorrect result.
   
   Consider adding a check:
   ```java
   if (Objects.isNull(contextPath) || decoratedPath.length() < 
contextPath.length() || !decoratedPath.startsWith(contextPath)) {
       shenyuContext.setRealUrl(decoratedPath);
   } else {
       String realURI = decoratedPath.substring(contextPath.length());
       shenyuContext.setRealUrl(realURI);
   }
   ```
