@ControllerAdviceを使用して例外を処理しています。残りのコントローラ用に@ControllerAdvice、残りのコントローラ用に1つ、Exception.classの例外を選択していますが、 NoHandlerFoundException.classを選択します。Spring @ControllerAdvice Handler例外がピッキングされていないNoHandlerFoundException
Spring 4.3.7.RELEASE、Java Config、Apache 8.5.12を使用しています。
以下MyWebInitializerクラス
public class MyWebInitializer extends
AbstractAnnotationConfigDispatcherServletInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
super.onStartup(servletContext);
servletContext.addListener(new RequestContextListener());
servletContext.addListener(new SpringSessionListener());
ServletRegistration.Dynamic dispatcher1 =
servletContext.addServlet("blackwellsjspservlet", new JspServlet());
dispatcher1.setLoadOnStartup(3);
dispatcher1.addMapping("*.do");
}
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { SpringRootConfig.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] { SpringWebConfig.class };
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
@Override
protected String getServletName() {
return "blackwellsmvcdispatcherservlet";
}
//Added to allow customised NoHandlerFoundPage
@Override
protected void customizeRegistration(ServletRegistration.Dynamic registration) {
boolean done = registration.setInitParameter("throwExceptionIfNoHandlerFound", "true"); // -> true
if(!done) throw new RuntimeException();
}
//Added to register a default profile
@Override
protected WebApplicationContext createServletApplicationContext() {
WebApplicationContext context = (WebApplicationContext) super.createServletApplicationContext();
((ConfigurableEnvironment) context.getEnvironment()).setDefaultProfiles("production");
return context;
}
}
マイSpringWebConfigがあるさ：非残りコントローラ用
@EnableWebMvc
@Configuration
public class SpringWebConfig extends WebMvcConfigurerAdapter {
@Autowired
private ServletContext servletContext;
@Autowired
Environment env;
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
@Bean
public InternalResourceViewResolver jspViewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/");
viewResolver.setViewNames("*.jsp");
return viewResolver;
}
@Bean
public Loader<?> templateLoader(){
return new ServletLoader(servletContext);
}
@Bean
public CustomSpringExtension springExtension() {
return new CustomSpringExtension();
}
@Bean
public PebbleEngine pebbleEngine() {
return new PebbleEngine.Builder()
.loader(this.templateLoader()).cacheActive(false)
.extension(springExtension())
.build();
}
@Bean
public ViewResolver pebbleViewResolver() {
PebbleViewResolver viewResolver = new PebbleViewResolver();
viewResolver.setPrefix("/WEB-INF/patternLab/");
viewResolver.setPebbleEngine(pebbleEngine());
viewResolver.setOrder(Ordered.LOWEST_PRECEDENCE - 5);
viewResolver.setViewNames("*.html");
return viewResolver;
}

return messageSource;
}

}

}

}
}
私のコントローラのアドバイス：残りのコントローラについては
@ControllerAdvice(annotations=Controller.class)
public class GlobalDefaultExceptionHandlerController {
private final Logger logger = LoggerFactory.getLogger(GlobalDefaultExceptionHandlerController.class);
ErrorList errorList;
/**
* This init binder register a custom editor to trim all fields coming
* from html
* @param binder
*/
@InitBinder
public void initBinder (WebDataBinder binder)
{
StringTrimmerEditor stringtrimmer = new StringTrimmerEditor(true);
binder.registerCustomEditor(String.class, stringtrimmer);
}
@ExceptionHandler(NoHandlerFoundException.class)
public ModelAndView handleNotFoundException(HttpServletRequest req, NoHandlerFoundException ex) {
ErrorMessage erMsg = new ErrorMessage();
erMsg.setError(ex.getMessage());
erMsg.setStackTrace(stackTrace);
erMsg.setException(ex);
ModelAndView model = new ModelAndView();
model.addObject("errorMessageObject", erMsg);
model.setViewName("pages/error-404.html");
return model;
}
@ExceptionHandler(Exception.class)
public ModelAndView handleAllException(HttpServletRequest req, Exception ex) throws Exception {
// Rethrow annotated exceptions or they will be processed here instead.
if (AnnotationUtils.findAnnotation(ex.getClass(), ResponseStatus.class) != null)
throw ex;
ErrorMessage erMsg = new ErrorMessage();
erMsg.setError(exceptionCode);
erMsg.setStackTrace(stackTrace);
erMsg.setException(ex);
ModelAndView model = new ModelAndView();
model.addObject("errorMessageObject", erMsg);
model.addObject("errMsg", ex.getMessage());
model.addObject("exceptionCode", exceptionCode);
model.setViewName("pages/error-500.html");
return model;
}
@RequestMapping(value = {"/SessionError"}, method = RequestMethod.GET)
public String sessionError() {
return "pages/error-500.html";
}
}
：
@RestControllerAdvice(annotations=RestController.class)
public class ApiExceptionHandlerController {
private final Logger logger = LoggerFactory.getLogger(ApiExceptionHandlerController.class);
@ExceptionHandler(Exception.class)
public ResponseEntity<Object> handleException(HttpServletRequest req, Exception ex){
logger.error("API Exception: {}", ex.getMessage(), ex);
logger.error("Path:{}, IP:{}", req.getServletPath(), req.getRemoteAddr());
ApiError apiError =
new ApiError(HttpStatus.INTERNAL_SERVER_ERROR, "Internal server error", ex.getMessage());
return new ResponseEntity<Object>(apiError, new HttpHeaders(), apiError.getStatus());
}
@ExceptionHandler(NoHandlerFoundException.class)
public ResponseEntity<Object> handleNotFoundException(HttpServletRequest req, Exception ex){
logger.error("API NoHandlerFoundException: {}", ex.getMessage(), ex);
logger.error("Path:{}, IP:{}", req.getServletPath(), req.getRemoteAddr());
ex.printStackTrace();
ApiError apiError =
new ApiError(HttpStatus.NOT_FOUND, ex.getMessage(), ex.getMessage());
return new ResponseEntity<Object>(apiError, new HttpHeaders(), apiError.getStatus());
}
}
どちらのコントローラーのアドバイスでも、いつかNoHandlerFoundExceptionが返されました。私はこれらのファイルの履歴の変更を見ていましたが、しばらく変更されていません。私は多分
@Override
protected void customizeRegistration(ServletRegistration.Dynamic registration) {
boolean done = registration.setInitParameter("throwExceptionIfNoHandlerFound", "true"); // -> true
if(!done) throw new RuntimeException();
}
真のは、残念ながら、私は春のブートを使用していない、あなたのデイブありがとうございます。また、AbstractAnnotationConfigDispatcherServletInitializerを継承するyウェブ初期化子でthrowExceptionIfNoHandlerFoundをtrueに設定しました。とにかく私は、Webイニシャライザの代わりにいくつかのプロパティを使ってみることができると思うでしょう。 –
