问题：

      spring cloud方式调用接口，参数中有一个UserInfo对象，其中updateTime属性为空，然后再被调用方用了一个另外一个UserInfo对象接收，在set方法中使用了updateTime.clone()方法，因为接收对象反序列化的时候set值updateTime为空，在调用方出现调用异常如下：

Request","exception":"org.springframework.http.converter.HttpMessageNotReadableException","message":"JSON parse error: null; nested exception is com.fasterxml.jackson.databind.JsonMappingException: N/A\n at [Source: java.io.PushbackInputStream@45729515; line: 1, column: 361] (through reference chain: com.jd.jr.code.entity.UserInfo[\"updateTime\"])","path":"/v1.0/git/auth"}

提示updateTime有问题；

解决办法：

将接收方UserInfo对象中的get/set方法改为如下即可

public Date getUpdateTime() {		return updateTime;	}	public void setUpdateTime(Date updateTime) {		this.updateTime = updateTime;	}
