Springboot 请求参数通知RequestBodyAdvice和响应通知ResponseBodyAdvice做日志的打印

1，请求参数的打印

@ControllerAdvice(basePackages = "控制器的命名空间")
public class LogRequestAdvice implements RequestBodyAdvice {
    Logger logger = LoggerFactory.getLogger(getClass());

    @Override
    public boolean supports(MethodParameter methodParameter, Type type, Class<? extends HttpMessageConverter<?>> aClass) {
        //判断是否有此注解
        boolean b = methodParameter.getParameterAnnotation(RequestBody.class) != null;
        //只有为true时才会执行afterBodyRead
        return b;
    }

    @Override
    public HttpInputMessage beforeBodyRead(HttpInputMessage httpInputMessage, MethodParameter methodParameter, Type type, Class<? extends HttpMessageConverter<?>> aClass) throws IOException {
        InputStream body = httpInputMessage.getBody();
        return new MappingJacksonInputMessage(httpInputMessage.getBody(), httpInputMessage.getHeaders());
    }

    @Override
    public Object afterBodyRead(Object o, HttpInputMessage httpInputMessage, MethodParameter methodParameter, Type type, Class<? extends HttpMessageConverter<?>> aClass) {
        //仅仅打印请求参数
        String s = JSON.toJSONString(o);
        /**
         * 去除注 回车 
 水平制表符 	 空格 s 换行 

         */
        String s2 = StringUtils.replaceBlankByLow(s);
        logger.info("请求参数为:{}", s2);
        return o;
    }

    @Override
    public Object handleEmptyBody(Object o, HttpInputMessage httpInputMessage, MethodParameter methodParameter, Type type, Class<? extends HttpMessageConverter<?>> aClass) {
        return null;
    }
2，请求参数的打印

@ControllerAdvice(basePackages = "控制器的命名空间")

public class LogResponseAdvice implements ResponseBodyAdvice<Object> {

    Logger logger = LoggerFactory.getLogger(LogResponseAdvice.class);

    @Override
    public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {
        return true;
    }

    @Override
    public Object beforeBodyWrite(Object body, MethodParameter returnType, MediaType selectedContentType, Class<? extends HttpMessageConverter<?>> selectedConverterType, ServerHttpRequest request, ServerHttpResponse response) {
        /**
         * 仅仅打印返回的参数参数
         */
        String s = JSON.toJSONString(body);
        logger.info("返回值为:{}", s);
        return body;
    }
