fastjson使用JSON.toJSON()方法出现*Error

        上个月底,邮箱每到中午都会收到告警邮件,内容如下:

logLevel = "ERROR" AND 
(message CONTAIN "java.lang.*Error" OR 
message CONTAIN "java.lang.OutOfMemoryError") 

        既然每天都那么准点,大概率是定时任务导致的了,很轻松就找到了每天中午12点开始跑的定时任务。但是问题代码出现在哪里呢?模拟了同样的入参,去调用该接口,可是无法重现该错误。而打印的日志是不完整的,如下:

        请教了同事,了解到JVM有个参数可以控制*Error错误日志的行数打印——MaxJavaStackTraceDepth 。配置 -XX:MaxJavaStackTraceDepth=-1 以后,第二天再次出现该错误时,可以准确定位到出现错误的代码行数,代码如下:

log.error("批量保存es数据存在不成功的情况,不成功的item:{}", JSON.toJSON(item));

        猜测是调用es保存接口失败后,返回的对象有循环引用,导致了*Error的出现,具体错误很难模拟,也就没继续探究根本原因,因此只是改为 JSON.toJSONString() 方法:

log.error("批量保存es数据存在不成功的情况,不成功的item:{}", JSON.toJSONString(item));

        注:项目中此时使用的fastjson版本号为 1.2.70
