Hibernate 3.0で8時間後に接続を取得しない

Question

私はhibenate.config.xmlをこのように設定しました...しかし、DB接続を取得していない時間がありました... MYSQLでは、wait-timeoutはデフォルト28800または8時間です..そしてここでそれはそれ以下です。それについての手掛かりはありません。

<property name="connection.url">jdbc:mysql://11.243.188.53/XXX</property> 
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property> 
    <property name="connection.username">admin</property> 
    <property name="connection.password">password1$</property> 
    <!-- Set AutoCommit to true --> 
    <property name="connection.autocommit"> false </property> 
    <property name="show_sql">true</property> 

    <!-- SQL Dialect to use. Dialects are database specific --> 
    <property name="dialect"> org.hibernate.dialect.MySQLDialect</property> 
    <property name="hibernate.hbm2ddl.auto">update</property> 




     <property name="hibernate.dbcp.maxActive">20</property> 
     <property name="hibernate.dbcp.maxIdle">10</property> 
     <property name="hibernate.dbcp.maxWait">-1</property> 
     <property name="hibernate.dbcp.whenExhaustedAction">2</property> 
     <property name="hibernate.dbcp.testOnBorrow">true</property> 
     <property name="hibernate.dbcp.testOnReturn">true</property> 
     <property name="hibernate.dbcp.validationQuery">SELECT 1</property> 
     <property name="hibernate.dbcp.testWhileIdle">true</property> 
     <property name="hibernate.dbcp.ps.maxActive">8</property> 
     <property name="hibernate.dbcp.ps.maxIdle">8</property> 
     <property name="hibernate.dbcp.ps.maxWait">60</property> 
     <property name="hibernate.dbcp.ps.whenExhaustedAction">1</property> 



     <!-- Disable second-level cache. --> 
    <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property> 
    <property name="cache.use_query_cache">false</property> 
    <property name="cache.use_minimal_puts">false</property> 
    <property name="max_fetch_depth">3</property> 

まだ数時間後に私はdb接続を取得できません。 java.net.SocketExceptionが：

Answer 1

あなたがそれで行われた後、あなたはHibernateセッションを解放することはできません可能性... OpenSessionInViewFilterを使用してみてくださいがあり、私は私が働いているプロジェクトの一つで同様の問題に直面していたfactory.openSession()

の使用を避けますon .. 原因を確かめる前にstacktraceを投稿できると非常に役に立ちます。

Answer 2

<property name="testOnBorrow" value="true"/> 

OR

  <prop key="hibernate.dbcp.validationQuery">select 1</prop> 
      <prop key="hibernate.dbcp.testOnReturn">true</prop> 

上記のXMLでデータベース接続豆に

をプロパティを追加し、接続に使用すると、プールから借りるたびにテストします。
