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.@Controllerpublic 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？

Answer 1

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"," ");

    }

}
