druid连接无法回收...

摘要: 在使用druid连接池的时候，removeAbandonedTimeout配置7200，但是每隔3个小时会出现connect holder is null，以前出现问题只要配置removeAbandonedTimeout和removeAbandoned就能解决。现在这个项目一直不行@wenshao2015-08-07 09:25:37 [ERROR] - com.alibaba.druid.pool.DruidDataSource -DruidDataSource.java(2021) -abandon connection, open stackTraceat java.lang.Thread.getStackTrace(Thread.java:1588)at com.alibaba.druid.pool.DruidDataSource.getConnectionDirect(DruidDataSource.java:1014)at com.alibaba.druid.filter.FilterChainImpl.dataSource_connect(FilterChainImpl.java:4544)at com.alibaba.druid.filter.logging.LogFilter.dataSource_getConnection(LogFilter.java:827)at com.alibaba.druid.filter.FilterChainImpl.dataSource_connect(FilterChainImpl.java:4540)at com.alibaba.druid.filter.stat.StatFilter.dataSource_getConnection(StatFilter.java:661)at com.alibaba.druid.filter.FilterChainImpl.dataSource_connect(FilterChainImpl.java:4540)at com.alibaba.druid.filter.FilterAdapter.dataSource_getConnection(FilterAdapter.java:2723)at com.alibaba.druid.filter.FilterChainImpl.dataSource_connect(FilterChainImpl.java:4540)at com.alibaba.druid.pool.DruidDataSource.getConnection(DruidDataSource.java:938)at com.alibaba.druid.pool.DruidDataSource.getConnection(DruidDataSource.java:930)at com.dimeng.framework.data.sql.mysql.AbstractPooledConnectionProvider.getConnection(AbstractPooledConnectionProvider.java:188)at com.dimeng.framework.service.achieve.SimpleServiceProvider$SimpleServiceSession$1.getConnection(SimpleServiceProvider.java:495)at com.dimeng.p2p.service.AbstractP2PService.getConnection(AbstractP2PService.java:32)at com.dimeng.p2p.service.PtAccountManageImpl.addRSAKey(PtAccountManageImpl.java:152)at com.dimeng.p2p.console.config.util.RSAKeyGeneral.onStartup(RSAKeyGeneral.java:20)at com.dimeng.framework.resource.achieve.ResourceInitializer.doStartup(ResourceInitializer.java:562)at com.dimeng.framework.resource.achieve.ResourceInitializer.initialize(ResourceInitializer.java:286)at com.dimeng.framework.resource.achieve.ResourceInitializer.onStartup(ResourceInitializer.java:294)at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5456)at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150)at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1559)at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1549)at java.util.concurrent.FutureTask.run(FutureTask.java:262)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145)at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)at java.lang.Thread.run(Thread.java:744)2015-08-07 09:53:27 [ERROR] -
