我使用@ExceptionHandler来管理我的所有异常,并为任何抛出异常的REST API返回JSON响应。 目前我管理两个异常,第一个是ResourceNotFoundException,它可以工作,但第二个,FileExtensionException,它不起作用。 它在eclipse控制台中抛出此异常,而没有任何其他响应。

这些是webservices调用的代码:
public FileSystemResource getZipFile(String fileName) throws FileExtensionException {
String ext=FilenameUtils.getExtension(fileName);
if (ext!= "zip")
throw new FileExtensionException(ext + " and not zip");
return new FileSystemResource(new File(fileName));
}
例外:
package matlab;
public class FileExtensionException extends RuntimeException {
private static final long serialVersionUID = 1L;
public FileExtensionException(String message){
super("The selected file has a different extension:" + message);
}
}
RestController:
@RequestMapping(value = "/files", method = RequestMethod.GET)
public Response<Collection<FileModel>> getAllFiles(@RequestParam(value="path", defaultValue="/home") String path) throws ResourceNotFoundException {
Collection<FileModel> result;
result = file.getAllFiles(path);
return new Response<Collection<FileModel>>(HttpStatus.OK.value(),result);
}
@RequestMapping(value = "/zipDownload", produces="application/zip", method = RequestMethod.GET)
@ResponseBody
public FileSystemResource getZip(@RequestParam(value="filePath", required=true) String filePath ) throws FileExtensionException{
return file.getZipFile(filePath);
}
ResourceNotFoundException
public class ResourceNotFoundException extends Exception {
private static final long serialVersionUID = 1L;
public ResourceNotFoundException(String path){
super("The specified path: "+ path +" doesn't exist");
}
}
ErrorControl
@ControllerAdvice
public class ErrorController {
/**
*
* @param e: exception thrown
* @return ErroreResponse
*/
@ExceptionHandler(Exception.class)
public @ResponseBody ErrorResponse errorHandler(Exception e){
//Make the exception by buildErrorResponse
return ErrorResponseBuilder.buildErrorResponse(e);
}
}
错误构建:
public class ErrorResponseBuilder {
public ErrorResponseBuilder() {
}
/**
* Build exception response beginning from exception
* @param e exception thrown
* @return ErrorResponse: response of an exception
*/
public static ErrorResponse buildErrorResponse(Exception e){
StringWriter errors = new StringWriter();
e.printStackTrace(new PrintWriter(errors));
return new ErrorResponse(HttpStatusManager.getHttpCode(e),e.getClass().getName(),e.getMessage(),errors.toString());
}
}
问题出在哪里? 感谢

尝试使用以下命令更新弹簧配置:
<bean id="methodHandlerExceptionResolver" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerExceptionResolver">
<property name="messageConverters">
<list>
<ref bean="stringHttpMessageConverter"/>
<ref bean="jsonHttpMessageConverter"/>
<ref bean="marshallingHttpMessageConverter"/>
</list>
</property>
</bean>
