Hikari连接不可用以及意外的多池问题

时间：2018-11-05 10:14:36

标签： java spring hibernate hikaricp connectionexception

在我的公司项目中，我们使用Hikari进行连接池管理。 [Hibernate 4.3.5 + Spring 4 + Java 1.8] 下面是配置

hibernate.connection.provider_class=com.zaxxer.hikari.hibernate.HikariConnectionProvider
hibernate.hikari.minimumIdle=5
hibernate.hikari.maximumPoolSize=10
hibernate.hikari.idleTimeout=60
hibernate.hikari.dataSourceClassName=com.mysql.jdbc.jdbc2.optional.MysqlDataSource

我们面临下面的第二个问题

  1. 由于某种原因，Hikari正在创建2个连接池HikariPool-1和HikariPool-2。

  2. 仅使用了HikariPool-2，即使经过一段时间，它仍会给出错误Connection is not available, request timed out after 30000ms

下面是Hikari启动日志和请求错误超时。

1 个答案:

答案 0 :(得分：2)

如果将Hibernate从4.3.5升级到4.3.6，则有Hibernate的官方ConnectionProvider：

  

更新：Hibernate 4.3.6+   从Hibernate 4.3.6开始，有一个来自Hibernate的官方ConnectionProvider类，应使用它代替HikariCP实现。该类称为org.hibernate.hikaricp.internal.HikariCPConnectionProvider。

因此，您应将com.zaxxer.hikari.hibernate.HikariConnectionProvider替换为org.hibernate.hikaricp.internal.HikariCPConnectionProvider
