    • getTargetObject

      public static <T> T getTargetObject(Object candidate)
      Get the target object of the supplied candidate object.

      If the supplied candidate is a Spring proxy, the target of the proxy will be returned; otherwise, the candidate will be returned as is.

      Type Parameters:
      T - the type of the target object
      Parameters:
      candidate - the instance to check (potentially a Spring AOP proxy; never null)
      Returns:
      the target object or the candidate (never null)
      Throws:
      IllegalStateException - if an error occurs while unwrapping a proxy

    • getUltimateTargetObject

      public static <T> T getUltimateTargetObject(Object candidate)
      Get the ultimate target object of the supplied candidate object, unwrapping not only a top-level proxy but also any number of nested proxies.

      If the supplied candidate is a Spring proxy, the ultimate target of all nested proxies will be returned; otherwise, the candidate will be returned as is.

      NOTE: If the top-level proxy or a nested proxy is not backed by a static TargetSource, invocation of this utility method may result in undesired behavior such as infinite recursion leading to a StackOverflowError.

      Type Parameters:
      T - the type of the target object
      Parameters:
      candidate - the instance to check (potentially a Spring AOP proxy; never null)
      Returns:
      the target object or the candidate (never null)
      Throws:
      IllegalStateException - if an error occurs while unwrapping a proxy
