使用拦截器对前端传入的字符串进行trim操作

 　　@Before("apiItf()")
     public void before(JoinPoint joinPoint) throws Exception {
         Object[] args = joinPoint.getArgs();
         if (args != null) {
             Method proxyMethod = ((MethodSignature) joinPoint.getSignature()).getMethod();
             ApiOperation apiOperation = proxyMethod.getAnnotation(ApiOperation.class);
             log.info("[" + apiOperation.value() + "] Request {}", JacksonUtils.jsonObjectSerializer(joinPoint.getArgs()));

             Object[] object = joinPoint.getArgs();
             Object request = object[0];
             Field[] fields = request.getClass().getDeclaredFields();
             for (Field field : fields) {
                 String name = field.getName();
                 name = name.substring(0, 1).toUpperCase() + name.substring(1);
                 if (field.getGenericType().getTypeName().equals("java.lang.String")) {
                     Method getField = request.getClass().getMethod("get" + name);
                     Method setFiled = request.getClass().getMethod("set" + name, new Class[]{String.class});
                     String value = (String) getField.invoke(request);
                     if (!Strings.isNullOrEmpty(value)) {
                         setFiled.invoke(request, new Object[]{value.trim()});
                     }
                 }
             }
         }
     }
