线上运维－打log也要看基本法

前言

今天跟进一个线上问题，full gc频繁。

分析过程

工具
jprofiler分析
首先是string相关的一些调研

string类型的点点滴滴

1.首先参考自己之前写的随笔字符串那些事
2.java6 7 8字符串常量池的区别

7，8移动到了堆中，可以配置大小，jvm参数：PrintStringTableStatistics可以打印使用信息

3.java内存分配和String类型的深度解析
4.java string常量池的几个例子

怀疑logger导致的内存泄漏
a memory leak caused by log4j logger
memory leak in log4j hierarchy
看了这两篇相关的issue，和我的case不一样啊，我的logger都是static。
另外，log4j开发组不可能说打了info之后还保持对这个string的引用啊，应该被gc掉（logger 源码）
怀疑是string过长，直接进入老年代导致的
参考jvm内存分配jvm内存管理

结论

log.info打印了很长的string,进入老年代，频繁触发full gc

解决和经验

code review要注意，log的打印也要放进去

1.首先是debug日志，一定要使用类似slf4j的占位符来进行处理
2.不能打印太长的string

其中一个log info的实际例子
