title: Spring boot error handling, keeping support for standard properties support
body: <p>I am trying to implement an error handler for javax.validation.ConstraintViolationException.</p>
  <p>This exception, in controller level, is giving 500 error. It should be 400.</p>
  <p>To solve the issue, I am trying to implement an exception handler.
  But, what ever suggestions are available, wither doesn't work (rethrow exception as response status exception) or doesn't follow the spring boot properties (like server.error.include-exception).</p>
  <p>Ref: <a href="https://docs.spring.io/spring-boot/docs/current/reference/html/appendix-application-properties.html" rel="nofollow noreferrer">https://docs.spring.io/spring-boot/docs/current/reference/html/appendix-application-properties.html</a></p>
  <p><strong>Update:</strong></p>
  <p>Sample code:</p>
  <pre><code>@RestController
  @Validated
  public class Controller {
  
      @GetMapping(&quot;/&quot;)
      public ResponseEntity&lt;String&gt; get(
              @RequestParam @Size(max = 2) String id
      ) {
          return ResponseEntity.ok(id);
      }
  
  }
  </code></pre>
  <p>Sample response on id = 123:</p>
  <pre><code>{
      &quot;timestamp&quot;: &quot;2021-03-31T09:11:41.605+00:00&quot;,
      &quot;status&quot;: 500,
      &quot;error&quot;: &quot;Internal Server Error&quot;,
      &quot;message&quot;: &quot;get.id: size must be between 0 and 2&quot;,
      &quot;path&quot;: &quot;/&quot;
  }
  </code></pre>
  <p>Sample stack trace:</p>
  <pre><code>2021-03-31 15:57:12.035 ERROR 33228 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is javax.validation.ConstraintViolationException: get.id: size must be between 0 and 2] with root cause
