如何在Spring Boot / MVC中创建错误处理程序（404、500…）？

spring

我试图在Spring Boot / MVC中创建CUSTOM全局错误处理程序。我读了很多文章，什么都没有…：/请帮我。

我尝试创建这样

@Controller
public class ErrorPagesController {

    @RequestMapping("/404")
    @ResponseStatus(HttpStatus.NOT_FOUND)
    public String notFound() {
        return "/error/404";
    }

    @RequestMapping("/403")
    @ResponseStatus(HttpStatus.FORBIDDEN)
    public String forbidden() {
        return "/error/403";
    }

    @RequestMapping("/500")
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    public String internalServerError() {
        return "/error/500";
    }

}

我用这种方式：

`

@Configuration
public class ErrorConfig implements EmbeddedServletContainerCustomizer {
    @Override
    public void customize(ConfigurableEmbeddedServletContainer container) {
        container.addErrorPages(new ErrorPage(HttpStatus.NOT_FOUND, "/404"));
    }
}

你可以尝试以下代码：

@ControllerAdvice
public class ExceptionController {
    @ExceptionHandler(Exception.class)
    public ModelAndView handleError(HttpServletRequest request, Exception e)   {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, "Request: " + request.getRequestURL() + " raised " + e);
        return new ModelAndView("error");
    }

    @ExceptionHandler(NoHandlerFoundException.class)
    public ModelAndView handleError404(HttpServletRequest request, Exception e)   {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, "Request: " + request.getRequestURL() + " raised " + e);
        return new ModelAndView("404");
    }
}

@Arash的附加功能 你可以添加一个BaseController可以扩展的新类，该类处理从异常到的转换http response。

     import com.alexfrndz.pojo.ErrorResponse;
     import com.alexfrndz.pojo.Error;
     import com.alexfrndz.pojo.exceptions.NotFoundException;
     import org.springframework.http.HttpStatus;
     import org.springframework.http.ResponseEntity;
     import org.springframework.web.bind.annotation.ExceptionHandler;
     import org.springframework.web.bind.annotation.ResponseBody;
     import org.springframework.web.bind.annotation.ResponseStatus;

     import javax.persistence.NoResultException;
     import javax.servlet.http.HttpServletRequest;
     import java.util.List;

     @Slf4j
     public class BaseController {

    @ExceptionHandler(NoResultException.class)
    public ResponseEntity<Exception> handleNoResultException(
            NoResultException nre) {
        log.error("> handleNoResultException");
        log.error("- NoResultException: ", nre);
        log.error("< handleNoResultException");
        return new ResponseEntity<Exception>(HttpStatus.NOT_FOUND);
    }


    @ExceptionHandler(Exception.class)
    public ResponseEntity<Exception> handleException(Exception e) {
        log.error("> handleException");
        log.error("- Exception: ", e);
        log.error("< handleException");
        return new ResponseEntity<Exception>(e,
                HttpStatus.INTERNAL_SERVER_ERROR);
    }

    @ExceptionHandler(NotFoundException.class)
    @ResponseStatus(value = HttpStatus.NOT_FOUND)
    @ResponseBody
    public ErrorResponse handleNotFoundError(HttpServletRequest req, NotFoundException exception) {
        List<Error> errors = Lists.newArrayList();
        errors.add(new Error(String.valueOf(exception.getCode()), exception.getMessage()));
        return new ErrorResponse(errors);
    }
   }
