Java 对于任何运行时错误，如何让@ExceptionHandlers在默认为异常处理程序之前处理特定的异常？

我想使用@ExceptionHandler来处理任何Hibernate异常。如果异常不是Hibernate异常，则运行时错误的@ExceptionHandler将处理该异常

问题是，运行时异常总是优先于Hibernate异常处理程序。这意味着，发生的任何hibernate异常都将由通用运行时异常处理程序处理

如何确保Hibernate异常由其异常处理程序处理，而不是由运行时异常处理

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

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

    myLogger.warning(message);

    theModel.addAttribute("exception", message);

    return "testing";
}

// handle any other runtime/unchecked exception and log it

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

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

    theModel.addAttribute("exception", message);

    return "testing";
}'

您可以通过以下方式检查异常是否为HibernateException的实例：

@ExceptionHandler(RuntimeException.class)
public String handleRuntimeExceptions(RuntimeException exc, Model theModel) {
    if (exc instanceof HibernateException) {
        return handleHibernateException((HibernateException) exc.getCause(), theModel);
    } else if (exc.getCause() instanceof HibernateException) {
        HibernateException hibernateException = (HibernateException) exc.getCause();
        return handleHibernateException(hibernateException, theModel);
    }
    String message = "An error has occurred: " + exc.getLocalizedMessage() + "\n" + exc.getCause().toString() + "\r\n";
    myLogger.warning(message);
    theModel.addAttribute("exception", message);
    return "testing";
}
