Hibernate异常继续由RuntimeException.class而不是HibernateException.class处理

Question

I have a ControllerAdvice set up, with two exception handlers; one for any Hibernate exception (HibernateException.class) and one for any other Runtime exception (RuntimeException.class)

@ExceptionHandler(HibernateException.class)
public String handleHibernateException(HibernateException exc, Model theModel) {

    String message = "An error has occured: " + exc.getLocalizedMessage() + "\r\n";

    myLogger.warning(message);

    theModel.addAttribute("exception", message);

    return "testing";
}


@ExceptionHandler(RuntimeException.class)
public String handleRuntimeExceptions(RuntimeException exc, Model theModel) {

    if (exc instanceof HibernateException) {

        return handleHibernateException((HibernateException) exc.getCause(), theModel);
    }   

    String message = "An error has occured: " + exc.getLocalizedMessage() + "\n"
            + exc.getCause().getCause().toString() + "\r\n";
    myLogger.warning(message);

    theModel.addAttribute("exception", message);

    return "testing";

I'm testing this out by messing up my query statements, which gives me a QuerySyntaxException; a subclass of HibernateException. And yet, it is still handled by my Runtime exception method.

我认为@ExceptionHandler完全匹配了QuerySyntaxException的Exact Exception名称。您可以尝试使用QuerySyntaxException。
