关于 Spring @ControllerAdvice 官方文档翻译问题

This topic created in 2157 days ago, the information mentioned may be changed or developed.

原文： https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-error-handling

原文中有这么一段

其中:

if YourException is thrown by a controller defined in the same package as AcmeController

这个 defined 修饰的是 controller 还是 YourException 。。？

假如我有个 a,b,c 三个 module, a 和 b 都依赖 c. c 中有一个异常 CException

public class CException extends RuntimeException {}

分别在 a 和 b 中的某个 controller 抛出, 并且 a 和 b 中分别定义了 ControllerAdvice

@ControllerAdvice(basePackageClasses = AController.class)
public class AControllerAdvice {

    @ExceptionHandler(CException.class)
    public ResponseEntity handleCException() {
    	// ...
    }
}

@ControllerAdvice(basePackageClasses = BController.class)
public class BControllerAdvice {

    @ExceptionHandler(CException.class)
    public ResponseEntity handleCException() {
    	// ...
    }
}

哪个 advice 能拦截到? 还是说要根据 order 来判断..?
