@ExceptionHandler是Spring框架提供的注解,用于统一处理方法抛出的异常。通过在方法上标注@ExceptionHandler注解,并指定异常类型,可以在发生异常时执行相应的异常处理逻辑。例如,在GlobalExceptionHandler类中可以定义多个@ExceptionHandler方法,每个方法对应不同的异常类型,通过指定不同的异常类型来实现不同异常的处理逻辑。优先级方面,Spring框架会根据异常类型的继承关系来确定异常处理器的优先级,继承关系越具体的异常处理器优先级越高。这样在发生异常时,Spring会根据异常类型选择对应的@ExceptionHandler方法来处理异常,并返回相应的处理结果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
