我使用hibernate和oracle，
我在一段时间内没有使用我的申请时出现此错误：

我的目标是知道如何在迷失后重新建立连接。
我在_BaseRootDAO中添加了这段代码：
protected Session getSession(String configFile) {
if ((null != session) && session.isOpen()) {
return session;
} else if (null != sessionFactory) {
Session s = currentSession.get();
if ((null == s) || !s.isOpen()) {
s = sessionFactory.openSession();
currentSession.set(s);
} else {
try {
HibernateWork hibernateWork = new HibernateWork("SELECT 1 FROM DUAL");
s.doWork(hibernateWork);
} catch (Exception e) {
System.err.println("------ Connection is closed");
s = sessionFactory.openSession();
currentSession.set(s);
}
}
return s;
} else {
Session s = currentSession.get();
if ((null == s) || !s.isOpen()) {
s = getSessionFactory(configFile).openSession();
currentSession.set(s);
}
return s;
}
}
我在applicationContext-db.xml中创建了这个配置：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

答案 0 :(得分：0)
你在getSession（）方法中的表现并不好看 主要是因为你不应该处理这个级别的连接。
应该管理连接的是数据源和连接池 您的问题的答案必须在数据源配置中。
Here是您使用的数据源的文档
我猜您应该使用validationQuery和testOnBorrow
尝试这样的事情（也需要一些时间来理解链接中数据源的参数）：
<beans>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
<property name="validationQuery" value="SELECT 1 FROM DUAL"/>
<property name="url" value="jdbc:oracle:thin:@192.168.0.22:1521:testSid"/>
<property name="username" value="testUser"/>
<property name="password" value="testUser"/>
<property name="maxActive" value="1500"/>
<property name="maxIdle" value="1000"/>
<property name="maxWait" value="20000"/>
<property name="defaultAutoCommit" value="true"/>
<property name="removeAbandoned" value="true"/>
<property name="removeAbandonedTimeout" value="3600"/>
</bean>
</beans>
