# 1.问题 #

接上一篇[《【一天一坑系列】Springcloud服务接口请求超时》][Springcloud]请求超时问题，继续解决请求时报的请求体缺失问题。

问题如下图：

该问题是在查看线上异常日志时发现，但并没有对线上业务产生很大影响，可能是并发量并不高。但是刚好业务不很忙，所以开始优化这个异常问题。因为是偶现，所以觉得应该不是代码层面的问题，因为如果是代码层面的问题，那应该会高频率出现问题。

--------------------

# 2.解决 #

①说下个人解决问题时的思路，一开始认为不是代码层面问题。于是考虑是否是网关层面或是Nginx限流等，导致请求体缺失。

②后来，在本地运行代码。通过Jmeter压测工具，对异常接口进行压测，发现偶现一个异常：

feign.codec.DecodeException: JSON parse error: Can not deserialize value of type java.util.Date from String "2017-04-27 17:20:23": not a valid representation (error: Failed to parse Date value '2017-04-27 17:20:23': Unparseable date: "2017-04-27 17:20:23"); nested exception is com.fasterxml.jackson.databind.exc.InvalidFormatException: Can not deserialize value of type java.util.Date from String "2017-04-27 17:20:23": not a valid representation (error: Failed to parse Date value '2017-04-27 17:20:23': Unparseable date: "2017-04-27 17:20:23")

于是定位到错误所在，原来是因为分布式接口当中，有feign调用，然后在调用过程中因jackson日期反序列化问题导致。

③最终解决方案

在application.xml中加入如下配置：

spring.mvc.date-format=yyyy-MM-dd HH:mm:ss
    spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
    spring.jackson.time-zone=GMT+8

最后再次压测，没有再出现了！！！这种偶现问题，确实很难排查，花了不少时间，不过还得冷静分析与找对方向。希望可以帮到遇到同样问题的朋友！！

--------------------

# 3.补充 #

问题分析：对于上面的请求参数体缺失，因为是在服务器上，由全局异常捕捉到的，所以其实并没有提供明确的异常源头代码。后来，本人在开发环境，通过Jmeter压测工具，在本地模拟请求。最终定位到具体原因，该异常是由于分布式服务当中，同一个请求中，因某个服务的方法调用时，发生了Feign的时间格式反序列化错误（这个才是异常根源），从而导致请求当中出现报错。但是这里有一个疑惑点，这种异常在请求当中并不是一定出现，而是偶现。所以当时排查的时候，也给我产生了一定的迷惑。

解决方式：

其实网上有很多种，如下：

①//在实体类的日期字段上方加注解，如下：

@JsonFormat(locale="zh", timezone="GMT+8", pattern="yyyy-MM-dd HH:mm:ss")

②以及此链接中的方式：[http://www.manongjc.com/article/33231.html][http_www.manongjc.com_article_33231.html]

方式很多，但是我这边的使用的全局方式，因为以第一种方式，我个人感觉是治标不治本，不推荐！

而我的问题也是通过上面的配置方法解决。

--------------------

2020-1-7再次补充：

经线上测试验证，请求体丢失原因并非此日期格式化问题导致，但日期格式化也是请求报错的一个问题。而对于请求体缺失问题，在线上也是偶现，并且没有业务影响。目前还没没有找到具体原因，推测是由于前端的预请求options造成。后续跟进更新。同时希望有经验的大佬不吝赐教，这个问题的解决方式。
