How to return response code 400 instead of stack trace or ignoring json attribute?

Question

When I send unsupported JSON request I receive stack trace from Jackson that it doesn't have this property. On the @JsonIgnoreProperties(ignoreUnknown = true) I just got a response without necessary obtaining as expected. But how can I return for example 400 or another response code without stack trace? org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "dave" (Class com.atlassian.troubleshooting.jfr.domain.JfrSettings), not marked as ignorable at [Source: org.apache.catalina.connector.CoyoteInputStream@8aaf377; line: 1, column: 14] (through reference chain: com.atlassian.troubleshooting.jfr.domain.JfrSettings["dave"]) at org.codehaus.jackson.map.exc.UnrecognizedPropertyException.from(UnrecognizedPropertyException.java:53) at org.codehaus.jackson.map.deser.StdDeserializationContext.unknownFieldException(StdDeserializationContext.java:267) JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

For me HttpMessageNotReadableException is thrown and UnrecognizedPropertyException is the nested exception. you can use SimpleMappingExceptionResolver and configure it like: @Configuration public class CustomConfiguration implements WebMvcConfigurer { @Bean public SimpleMappingExceptionResolver simpleMappingExceptionResolver(){ var mappings = new Properties(); mappings.setProperty("HttpMessageNotReadableException", "errorpage"); var statusCode = new Properties(); statusCode.setProperty("errorpage", String.valueOf(HttpServletResponse.SC_BAD_REQUEST)); var exeptionResolver = new SimpleMappingExceptionResolver(); exeptionResolver.setStatusCodes(statusCode); exeptionResolver.setExceptionMappings(mappings); return exeptionResolver; } @Override public void configureHandlerExceptionResolvers( List resolvers) { resolvers.add(simpleMappingExceptionResolver()); } } or use @ControllerAdvice like: @ControllerAdvice public class ControllerAdvisor { @ExceptionHandler(HttpMessageNotReadableException.class) public ResponseEntity handleCityNotFoundException( HttpMessageNotReadableException ex, WebRequest request) { // do stuff with ex and request return new ResponseEntity<>("body", HttpStatus.BAD_REQUEST); } } also as I said in the beginning the exception is HttpMessageNotReadableException and UnrecognizedPropertyException is just nested inside HttpMessageNotReadableException. If you use UnrecognizedPropertyException in above codes it won't work.
