How to Prevent Stack Trace from Spring Rest API Exception Handler returning HTTP status 400
java, json, rest, spring, spring-mvc
Solution
You can just add the application property `server.error.include-stacktrace=never` which responds for including stack trace into 400 responses.
Problem
I am trying to handle Validation exception in Spring Rest service like code given below: ``` @Produces("application/json") @ExceptionHandler(MethodArgumentNotValidException.class) @ResponseStatus(HttpStatus.BAD_REQUEST) public @ResponseBody ResponseEntity<ValidationErrorDTO> processValidationError(MethodArgumentNotValidException ex) { BindingResult result = ex.getBindingResult(); List<FieldError> fieldErrors = result.getFieldErrors(); ResponseEntity<ValidationErrorDTO> re = new ResponseEntity<>(processFieldErrors(fieldErrors), HttpStatus.BAD_REQUEST); return re; } ``` However when this code executes, it returns stack trace appended to the JSON response. I want to get rid of this stack trace and only return JSON error response. Is this possible with Spring 3.1? ``` {"fieldErrors": [{"field":"type","message":"Pattern.shippingAddress.type"}]}<pre>javax.servlet.ServletException: 400 Bad Request null at com.ebay.raptor.kernel.dispatcher.HttpDispatchCommand.execute(HttpDispatchCommand.java:142) at com.ebay.ebox.pres.cmd.preshandler.CommandDispatchHandler.handleRequest(CommandDispatchHandler.java:59) at com.ebay.ebox.pres.cmd.preshandler.CommandDispatchHandler.handleRequest(CommandDispatchHandler.java:13) at com.ebay.ebox.pres.cmd.preshandler.CommandHandlerFactory$CalHandler.handleRequest(CommandHandlerFactory.java:114) at com.ebay.ebox.pres.cmd.preshandler.CommandHandlerFactory$CalHandler.handleRequest(CommandHandlerFactory.java:75) at com.ebay.kernel.pipeline.RequestPipeline.invoke(RequestPipeline.java:18) at com.ebay.kernel.pipeline.RequestPipeline.invoke(RequestPipeline.java:12) at com.ebay.kernel.pipeline.BasePipeline.callHandler(BasePipeline.java:75) at com.ebay.kernel.pipeline.BasePipeline.execute(BasePipeline.java:53) at com.ebay.ebox.pres.stage.BaseCommandRequestStageImpl.doWork(BaseCommandRequestStageImpl.java:64) at com.ebay.kernel.stage.StageDriver.execute(StageDriver.java:55) at com.ebay.ebox.pres.cmd.WebCommandImpl.execute(WebCommandImpl.java:30) at com.ebay.raptor.web.RaptorFrontController.process(RaptorFrontController.java:338) at com.ebay.raptor.web.RaptorFrontController.doPost(RaptorFrontController.java:554) at com.ebay.raptor.web.RaptorGenericController.service(RaptorGenericController.java:64) at javax.servlet.http.HttpServlet.service(HttpServlet.java:728) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:305) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:749) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:487) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:379) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:339) at com.ebay.raptor.kernel.filter.RaptorDispatchFilter.doFilter(RaptorDispatchFilter.java:52) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at com.thetransactioncompany.cors.CORSFilter.doFilter(CORSFilter.java:195) at com.thetransactioncompany.cors.CORSFilter.doFilter(CORSFilter.java:266) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:222) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:123) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:502) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:171) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:99) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:953) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:408) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1023) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:589) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:310) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744) </pre> ```
