Spring Jdbc模板中的频繁连接重置

我正在使用JDBC模板连接到oracle数据库。经常我会得到异常，几秒后就会消失。当我重试时，我将能够执行sql查询。

我的连接池设置

datasource.maxActive=10
datasource.maxIdle=10
datasource.initialSize=5
datasource.maxWait=5000

我怀疑它是

中列出的oracle驱动程序问题

Oracle JDBC intermittent Connection Issue

https://community.oracle.com/message/3795101

http://www.usn-it.de/index.php/2009/02/20/oracle-11g-jdbc-driver-hangs-blocked-by-devrandom-entropy-pool-empty/

我在jvm中设置了以下属性。

-Djava.security.egd=file:///dev/urandom

但它仍然没有帮助。

任何人都面临/面临类似的问题？

1 个答案:

答案 0 :(得分：1)

找到错误参考，所以我会发表评论作为答案。

请参阅Java bug 6202721

即使您明确请求/dev/urandom，Java静默也会将其替换为/dev/random，这无法跟上Linux上的熵生成。

请尝试指定/dev/./urandom。替换基于显式字符串值进行，如果您想真正强制 urandom，则必须提供与字符串不匹配但仍解析为相同路径的备用表单。
