springboot中的错误处理

Question

springboot默认会用whitelabel来显示错误视图，可以实现ErrorController来自定义.

@Controller

public class ErrorHandleController implements ErrorController {

    @Override

    public String getErrorPath() {

        return "error";

    }

    @RequestMapping

    public String errorHandle() {

        return getErrorPath();

    }

}

自己定义了这么一个处理器，结果把css，js这里当错误给处理了，这么解决啊？

你可以直接定义一个错误处理器，在service层抛出相关的自定义异常，然后在PersonalExceptionHandler进行相关的处理。 @ControllerAdvice   public class PersonalExceptionHandler {    @ExceptionHandler(EntityNotFoundException.class)    @ResponseStatus(HttpStatus.NOT_FOUND)    @ResponseBody    SimpleErrorMessage handleException(EntityNotFoundException exception){        log.debug("Entity Not Found Exception {}",exception.getMessage());        log.trace(exception.getMessage(),exception);        return new SimpleErrorMessage("Entity not found","This resource was not found");    }    @ExceptionHandler({UsernameNotFoundException.class})    @ResponseStatus(HttpStatus.UNAUTHORIZED)    @ResponseBody    SimpleErrorMessage handleException(UsernameNotFoundException exception){        log.debug("Username not found {}",exception.getLocalizedMessage());        log.trace(exception.getMessage(),exception);        return new SimpleErrorMessage("Unaouthorized"," ");    }}
