我有一个Spring 4.1.6的应用程序,我创建了一个用于处理所有异常的类,如下所示:

@ControllerAdvice
public class RestControllerAdvice {
...
@ExceptionHandler({Exception.class})
public ResponseEntity<Result> handleException(final Exception ex) {
    Result res = new Result();
    try {
        Exception root = (Exception) ExceptionUtils.getRootCause(ex);
        if (root == null) {
            root = ex;
        }
        if (root instanceof BindException) {
            handleBindException(root, res);
        } else if (root instanceof ConstraintViolationException) {
            handleConstraintViolations(root, res);
        } else if (root instanceof NoHandlerFoundException) {
            handleNoHandlerFoundException(root, res);
        } else {
            logError(res, ex);
        }
    } catch (Exception e) {
        logError(res, e);
    } finally {
        if (!res.hasErrors()) { …

Currently I have classes with several nested classes inside is, like:

public class Foo {

  private Bar bar;

  //getter & setter

  public class Bar {

    private Abc abc;

    //getter & setter

    public class Abc {
      @RequiredParam
      private String property;

      //getter & setter
    }
  }

}

I am trying to get the value of the fields but I am having a hard time how to achieve this.

So far I have:

  public static boolean isValid(Object paramClazz) throws Exception {
    List<Class> classes …
