spring mvc aop拦截controller层获取RequestBody反序列化后参数

最近，为了解耦，把一逻辑从interceptor抽出来，放在aop中处理，需要得到RequestBody。如下：

@Aspect
@Configuration
public class CheckAspect {
    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    // 定义切点Pointcut  自行写入对应的controller包路径
    @Pointcut("execution(* com.hs.yido.controller.*.*(..))")
    public void excudeService() {
    }

    @Around("excudeService()")
    public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
        RequestAttributes ra = RequestContextHolder.getRequestAttributes();
        ServletRequestAttributes sra = (ServletRequestAttributes) ra;
        HttpServletRequest request = sra.getRequest();

        String url = request.getRequestURL().toString();
        String method = request.getMethod();
        String uri = request.getRequestURI();
        String queryString = request.getQueryString();
        //这里可以获取到get请求的参数和其他信息
        logger.info("请求开始, 各个参数, url: {}, method: {}, uri: {}, params: {}", url, method, uri, queryString);
        //重点 这里就是获取@RequestBody参数的关键  调试的情况下 可以看到o变量已经获取到了请求的参数
        Object[] o = pjp.getArgs();

        // result的值就是被拦截方法的返回值
        Object result = pjp.proceed();
        return result;
    }

}
