    text
    copied!<p>I'm using Spring 3.2.0. According to <a href="https://stackoverflow.com/a/3230352/1391249">this</a> answer, I have the same method in my annotated controller which implements the <code>HandlerExceptionResolver</code> interface such as,</p> <pre><code>public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception exception) { Map&lt;String, Object&gt; model = new HashMap&lt;String, Object&gt;(0); if (exception instanceof MaxUploadSizeExceededException) { model.put("msg", exception.toString()); model.put("status", "-1"); } else { model.put("msg", "Unexpected error : " + exception.toString()); model.put("status", "-1"); } return new ModelAndView("admin_side/ProductImage"); } </code></pre> <p>and the Spring configuration includes,</p> <pre><code>&lt;bean id="filterMultipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"&gt; &lt;property name="maxUploadSize"&gt; &lt;value&gt;10000&lt;/value&gt; &lt;/property&gt; &lt;/bean&gt; </code></pre> <p>When the file size exceeds, the preceding method should be invoked and it should automatically handle the exception but it doesn't happen at all. The method <code>resolveException()</code> is never called even though the exception occurs. What is the way to handle this exception? Am I missing something?</p> <p>The same thing is also specified <a href="http://www.raistudies.com/spring/spring-mvc/file-upload-spring-mvc-annotation/" rel="nofollow noreferrer">here</a>. I'm not sure why it doesn't work in my case.</p> <hr> <p>I have tried the <a href="http://www.baeldung.com/2013/01/31/exception-handling-for-rest-with-spring-3-2/#controlleradvice" rel="nofollow noreferrer">following approach</a> with <a href="http://static.springsource.org/spring-framework/docs/3.2.0.M2/api/org/springframework/web/bind/annotation/ControllerAdvice.html" rel="nofollow noreferrer"><code>@ControllerAdvice</code></a> but it didn't work either.</p> <pre><code>package exceptionhandler; import org.springframework.http.HttpHeaders; import org.springframework.http.HttpStatus; import org.springframework.http.ResponseEntity; import org.springframework.web.bind.annotation.ControllerAdvice; import org.springframework.web.bind.annotation.ExceptionHandler; import org.springframework.web.context.request.WebRequest; import org.springframework.web.multipart.MaxUploadSizeExceededException; import org.springframework.web.servlet.mvc.method.annotation.ResponseEntityExceptionHandler; @ControllerAdvice public final class RestResponseEntityExceptionHandler extends ResponseEntityExceptionHandler { @ExceptionHandler(value = {MaxUploadSizeExceededException.class}) protected ResponseEntity&lt;Object&gt; handleConflict(RuntimeException ex, WebRequest request) { String bodyOfResponse = "This should be application specific"; return handleExceptionInternal(ex, bodyOfResponse, new HttpHeaders(), HttpStatus.CONFLICT, request); } } </code></pre> <p>I have also tried to put the verbose - <code>Exception</code>.</p> <pre><code>@ExceptionHandler(value={Exception.class}) </code></pre> <p>The method <code>ResponseEntity()</code> is never invoked in any case.</p> <hr> <p>In general, I want to handle this exception per controller base (controller level), if possible. For this, one <code>@ExceptionHandler</code> annotated method should only be active for that particular controller, not globally for the entire application, since there are only a few web pages in my application that handle file uploading. When this exception is caused, I just want to show a user-friendly error message on the current page and not to redirect to the error page configured in the <code>web.xml</code> file. If this is not even feasible, then this exception should be handled anyway without any custom requirements I have just expressed.</p> <p>Neither of approaches worked for me. Nothing more about handling this exception I could find. Does it require additional configuration somewhere in XML files or otherwise?</p> <hr> <p>What I'm getting after the exception is thrown can be visible in the following <a href="https://i.stack.imgur.com/GrKgq.png" rel="nofollow noreferrer">snap shot</a>.</p> <p><img src="https://i.stack.imgur.com/GrKgq.png" alt="enter image description here"></p>
