Apache tomcat 6问题

[英]Apache tomcat 6 problem

 原文  2011-07-29 10:37:38  3   2    java/ mysql/ apache/ hibernate/ tomcat

问题描述

我已经开发了一个在Apache tomcat 6服务器上运行的应用程序。 为了开发该应用程序，我使用了Struts 2.0和Hibernate 3.0。 我面临的问题是，每当我启动tomcat服务器时，我的应用程序就可以正常运行，但是如果我超过12小时不使用它，则该应用程序会引发一些异常和500错误，但是如果我再次重启服务器它运行没有任何问题。 有人可以告诉我这里是什么问题，如果我12个小时不使用应用程序，为什么会崩溃。

这是例外

该错误通常是旧的JDBC连接导致的。 查看数据库连接池（DBCP）。 请参阅此链接中的“数据源”部分

尝试对数据源使用以下属性，以使连接有效期足够长，以防止发生错误。 

maxActive = 50
maxIdle = 25
minIdle = 5
initialSize = 5
minEvictableIdleTimeMillis = 60000
timeBetweenEvictionRunsMillis = 60000
maxWait = 10000
validationQuery = "/* ping */"

如果没有更多细节，很难给出准确的答案，但是在连接陈旧的情况下，此问题通常会显现出来。 您在应用程序中使用连接池吗？ 如果是，是否在使用前验证连接？
