我遇到了与数据库连接的问题，在应用程序暂停一段时间后，我返回并输入以下错误

01-08-2014 04:45:33 PM org.apache.catalina.core.StandardWrapperValve invoke
GRAVE: Servlet.service() para servlet springapp lanzó excepción
org.springframework.dao.DataAccessResourceFailureException: 
### Error querying database.  Cause: java.sql.SQLRecoverableException: Error de E/S: Software caused connection abort: recv failed

这是我的oracle数据源

将这些行添加到dataSource bean解决了这个问题：

<property name="validationQuery" value="SELECT 1 from dual" /> 
<property name="testOnBorrow" value="true" />

关于验证查询，您可以在此问题的答案中阅读：What is a validationQuery with respect to databases and JNDI?

＆＃34; testOnBorrow＆＃34;意味着在每个查询执行之前都会执行validationQuery。
