【中文标题】使用tomcat jdbc pool StatementCache拦截器时出错【英文标题】：Error while using tomcat jdbc pool StatementCache interceptor 【发布时间】：2015-03-20 17:52:24 【问题描述】：我正在使用带有“apache-tomcat-7.0.47”的tomcat jdbc 池作为我的应用服务器。当我不使用 StatementCache 拦截器时，一切正常。但是，一旦我在 context.xml 中声明 StatementCache 拦截器，我就会开始收到错误消息。以下是我的 context.xml 中的条目：
<Resource name="jdbc/myDB"
auth="Container"
type="javax.sql.DataSource"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
defaultAutoCommit="false"
testWhileIdle="true"
testOnBorrow="true"
testOnReturn="false"
validationQuery="SELECT 1 FROM DUAL"
validationInterval="30000"
timeBetweenEvictionRunsMillis="30000"
maxActive="100"
minIdle="10"
maxWait="10000"
initialSize="10"
removeAbandonedTimeout="60"
removeAbandoned="true"
logAbandoned="true"
minEvictableIdleTimeMillis="30000"
jmxEnabled="true"
jdbcInterceptors="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementCache;
org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer"
username="MYUSR"
password="myPWD"
appName="MYAPP"
driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@myIp/SSAGFD01"/>
以下是我得到的错误跟踪：

还有其他人遇到过这个错误吗？在我看来，第一条语句被执行并关闭。该语句被缓存。下一个数据库获取关闭的语句。我在我的应用程序中使用 spring 和 ibatis。我应该在应用程序中做一些事情以不关闭语句或如果关闭则可能打开语句？
【问题讨论】：
【参考方案1】：我们在使用 Tomcat JDBC 连接池时遇到了类似的问题。删除 StatementCache 正在解决它。这很奇怪，因为即使我们调用 statement.close()，如果启用了语句缓存，Tomcat 池也不会关闭语句。
我们添加了 StatementDecoratorInterceptor 来解决问题。
tomcat连接池https://bz.apache.org/bugzilla/show_bug.cgi?id=48392有bug
所以调用 resultSet.getStatement().close() 将关闭实际语句。
使用 StatementDecoratorInterceptor 来避免由于上述问题导致代码中的实际语句关闭。

【讨论】：
以上是关于使用tomcat jdbc pool StatementCache拦截器时出错的主要内容，如果未能解决你的问题，请参考以下文章
