我刚刚使用AWS中的MySQL部署在Tomcat 7上的Spring Boot应用服务器进入SIT阶段
Tomcat7在标准数据库服务器上使用MySQL的Ubuntu EC2实例上运行
最初id在我的hibernate.cfg.xml文件中设置我的数据库连接
然而我遇到过时连接问题
服务器启动后模式始终相同
1）大约24小时没有问题 2）24 - 48小时 - 数据库连接将开始失败，首先以大约1/10的速率然后到48小时后的大约2：3
大量阅读建议
a）我应该通过JNDI配置我的数据源 b）我不应该在数据库URL中使用自动连接，因为它已被弃用 c）使用testOnBorrow属性应该确保我的应用服务器不会尝试使用失败的连接
所以我继续前进并设置了
继承人我在server.xml中如何配置JDNI
<Resource name="jdbc/FootyPicksData"
auth="Container"
type="javax.sql.DataSource"
username="[my db user]"
password="[my DB passoword]"
url="jdbc:mysql://[my DB url]
driverClassName="com.mysql.jdbc.Driver"
maxActive="15"
maxIdle="3"
maxWait="5000"
removeAbandoned="false"
removeAbandonedTimeout="20"
logAbandoned="true"
validationQuery="select 1"
minEvictableIdleTimeMillis="3600000"
timeBetweenEvictionRunsMillis="1800000"
numTestsPerEvictionRun="10"
testWhileIdle="true"
testOnBorrow="true"
testOnReturn="false"
/>
所以我把它设置好然后我去了
大约24小时后出现了同样的问题 好吧，我认为这还不行，让我们查看日志现在我得到了一个不同的错误，但是完全相同的比例（24小时后10％ish，48小时后70％ish

很好，我再次谷歌和许多答案表明这是我通过Hibernate管理我的数据库会话的一个基本问题
此时值得补充的是，在设置Hibernate时，有两个主要的设计模式，一个是您自己明确打开和关闭连接，另一个是开始和提交事务的地方，您使用getSession（）获取会话，据我所知，将尝试抓住现有会话，如果没有，则打开一个
所以例如下面是我所有数据层服务如何工作的片段
public boolean saveOrUpdateLeagueMember(LeagueMember leagueMember) {
Session session = HibernateUtility.getSession();
session.beginTransaction();
try {
session.saveOrUpdate(leagueMember);
session.getTransaction().commit();
return true;
} catch (Exception e) {
System.out.println(e);
logger.error(e);
session.getTransaction().commit();
return false;
}
}
发生了什么事？是应用程序代码或池设置中的问题？
如果它的代码为什么24小时的罚款然后慢慢开始失败？
我的设置方式是否存在根本性的错误？
这种感觉最有可能，因为这是我试图在这里做的相当标准的事情......
