- Sample interceptor code
package com.my.interceptor;
public class MyInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle( ... ) throws Exception {
throw new Exception("test exception"); // throw test exception
}
}
- Sample controller code
package com.my.controller;
@RestController
@RequiredArgsConstructor
public MyController {
@GetMapping( "/my" )
public ResponseEntity getMy() {
...
}
}
- Sample exception handler code
package com.my.handler;
@RestControllerAdvice( basePackages = { "com.my.interceptor" } ) // Doesn't handle interceptor
// @RestControllerAdvice( basePackages = { "com.my.controller" } ) // Handle both interceptor and controller
public class MyExceptionHandler extends ResponseEntityExceptionHandler {
@ExceptionHandler( value = { Exception.class } )
public void handleException( HttpServletRequest request, Exception e) {
...
}
}
I want to handle exception from interceptor without creating custom exceptions.
But basePackages = { "com.my.interceptor" } in MyExceptionHandler doesn't handle exception from interceptor.
When I change basePackages to basePackages = { "com.my.controller" }, it handles both interceptor and controller.
Why this happen and how can I handle interceptor's exception only?
