SpringBoot重写handleOAuth2Exception返回JSON格式异常信息

SpringBootOauth2Server默认的code获取环节使用了303返回异常信息,并且没有可以设置的属性.为了将303信息替换为json返回, 选择使用@Around替换目标方法,实现解析目的 

@Component
@Aspect
@Order(1)
public class AuthorizationEndpointAdvice {
    // 切入点为AuthorizationEndpoint里面的三个handleException方法
	@Pointcut("execution(public * org.springframework.security.oauth2.provider.endpoint.AuthorizationEndpoint.handle*Exception(..))")
	public void pointCut() {
	}

	@Around("pointCut()")
	public ModelAndView test(ProceedingJoinPoint pjp) throws Throwable {

		Object[] args = pjp.getArgs();
		if (args != null && args[0] instanceof Exception) {
			//ClientRegistrationException/OAuth2Exception/HttpSessionRequiredException
			Exception exception = (Exception) args[0];
			
            //创建返回对象
			Result result = Result.failed(exception);
            // 使用JsonView将返回对象以json渲染
			ModelAndView modelAndView = new ModelAndView(new MappingJackson2JsonView()).addAllObjects(result.toMap());
			modelAndView.setStatus(HttpStatus.BAD_REQUEST);
			return modelAndView;
		}

		return (ModelAndView) pjp.proceed(args);
	}
}
