Question

我使用Camel sql组件对Oracle DB运行select查询。 war文件部署在Jboss EAP 6.1上。在配置下的配置文件中，我将track语句设置为true（即true）。因此，当连接返回到池时，Jboss会检查结果集是否已关闭。

我正在按如下方式配置sql组件：

//datasource is injected here
@Resource(mappedName = "java:/jdbc/OracleDS")
private DataSource dataSource;

... ...

//SQL component
SqlComponent sqlComponent = new SqlComponent();
sqlComponent.setDataSource(dataSource);
camelCtx.addComponent("sql", sqlComponent);

sql组件在recipientList中使用如下：

from("activemq:"+queue)
...
.recipientList(simple(getFromConfig(sqlStmtName)),"false")
..

sql语句没什么特别的。只是来自单个表的常规select语句。

在Jboss日志中，我看到了这个警告。

我检查了SqlProducer.java（第127行）。由于sql组件使用Spring JDBCtemplate，我认为结果集将被模板关闭。

关闭结果集有什么需要做的吗？

是的，这是Apache Camel中的一个错误。我已经记录了一张票，以便在将来的版本中修复此问题

Apache Camel SQL组件没有关闭结果集？
