多個ControllerAdvice優先級設定

多個ControllerAdvice，優先級由@Order決定，order的數值越小 則優先級越高。或者，實現Ordered接口，實現getOrder()方法。

import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;

@ControllerAdvice 
@Order(Ordered.HIGHEST_PRECEDENCE) 
class UserProfileExceptionHandler { 
    @ExceptionHandler(UserProfileException) 
    @ResponseBody 
    ResponseEntity<ErrorResponse> handleUserProfileException() { 
     .... 
    } 
} 

@ControllerAdvice 
@Order(Ordered.LOWEST_PRECEDENCE) 
class DefaultExceptionHandler { 

    @ExceptionHandler(RuntimeException) 
    @ResponseBody 
    ResponseEntity<ErrorResponse> handleRuntimeException() { 
     .... 
    } 
}
