Druid是什么？ Druid首先是Java语言中最好的数据库连接池，也是阿里巴巴的开源项目。Druid是阿里巴巴开发的号称为监控而生的数据库连接池，在功能、性能、扩展性方面，都超过其他数据库连接池，包括DBCP、C3P0、BoneCP、Proxool、JBoss DataSource等等等，秒杀一切。而且Druid已经在阿里巴巴部署了超过600个应用，经过好几年年生产环境大规模部署的严苛考验！ filters: stat,wall,log4j stat：Druid内置提供一个StatFilter,用于统计监控信息。如果需要配置访问页面可以参考，https://github.com/alibaba/druid/wiki/%E9%85%8D%E7%BD%AE_StatViewServlet%E9%85%8D%E7%BD%AE，我还没有研究这个，有研究的麻烦留意告诉一下，以后会找机会更新上来，毕竟很好用。 wall：Druid防御SQL注入攻击的WallFilter就是通过Druid的SQL Parser分析。Druid提供的SQL Parser可以在JDBC层拦截SQL做相应处理，比如说分库分表、审计等。 log4j：这个就是日志记录的功能，可以把sql语句打印到log4j供排查问题。 第一步：配置pom.xml <dependency> <groupId>mysql<

Our site get roughly 1M pv/day, and we use Tomcat for sure. I couldn't find much information about jdbc-pool , not sure if it's stable enough for production. Anyone got experience on it? and any configuration/tuning stuff for reference? As someone mentioned, BoneCP might be another choice. But seems it's discontinued (so sad...). Would it be a better choice? btw, HikariCP is too young, I would keep an eye on it as it's the latest/fastest CP so far I found. Thanks for any advice. I'm one of the authors of HikariCP. That said, the "new" Tomcat pool is among the best we've tested. It has a lot of

For a Java app outside of a J2EE container, which connection pool library is the best? I heard c3p0 is getting outdated. Jakarta's common pool library is no longer under development Therefore I'm left with BoneCP and DBPool . From what I can tell both have limited activity. The main difference I can see is performance, which BoneCP seems to win out with. However the documentation is pretty weak. Which database pool library have you used in the real world and why? What was the good and bad? At work we have used BoneCP (as the replacement for c3p0) and as far as I know haven't had any issues (I

I have an app on heroku that uses play. It was working fine for the longest time, but somewhat recently I started getting this: Caused by: java.sql.SQLException: Timed out waiting for a free available connection. at org.hibernate.engine.jdbc.internal.LogicalConnectionImpl.getConnection(LogicalConnectionImpl.java:169) ~[hibernate-core-4.1.9.Final.jar:4.1.9.Final] at com.jolbox.bonecp.BoneCP.getConnection(BoneCP.java:503) ~[bonecp-0.7.1.RELEASE.jar:0.7.1.RELEASE] which is caused by org.postgresql.util.PSQLException: FATAL: too many connections for role "ejmatdbwywaugk" Now this is pretty

Which JDBC connection pool library should I use for a new application project (not web application)? Apache DBCP has enough unresolved issues which are pushed until 2.0 I think. C3P0 development seems to be stopped. And both of them looks relatively slow . Proxool is dead. DBPool has almost no community (at least I've found no public one - no forums, no mailing lists...) Apache Tomcat Pool looks to be unusable without Tomcat I've found SQL Datasources article at Oracle website, but it seems, that it can be applied only to applets running in containers like servlets and web services. Should I
