fastjson循环引用异常

当一个对象的get方法中new了一个对象时，使用fastjson转成json串，会报循环引用异常，但用Gson转成json串，就没问题，fastjson可以解决这个问题吗？（org.springframework.web.servlet.mvc.method.annotation.ExtendedServletRequestDataBinder，这个类用fastjson打印就会报循环引用异常）

在这里用JSON.toJSONString(binder);的确没问题了，但用JSON.toJSON(binder);会导致死循环？

如果写个Controller，public void getSth(String name, String code)

方法使用x-www-form-urlencoded传递参数，然后通过AOP打印参数
log.info("\n方法:{}\n参数:{}", joinPoint.getSignature(), JSON.toJSONString(joinPoint.getArgs()));
还是会抛异常，异常信息：

toJSON没有做循环检测，先使用toJSONString吧
