我使用Hibernate 3.3並知道它與C3P0捆綁在一起。但是在hibernate.cfg.xml中添加C3P0屬性設置之後,classnotfound異常出現在控制檯中,然後我下載並在我的classpath中添加了c3p0-0.9.1.jar,並且C3P0開始工作。休眠C3P0 unreturnedConnectionTimeout和debugUnreturnedConnectionStackTraces不起作用
現在,當我使用Eclipse添加以下行到我的hibernate.cfg.xml:
<property name="hibernate.c3p0.
智能感知只顯示我:
hibernate.c3p0.acquire_increment
hibernate.c3p0.idle_test_period
hibernate.c3p0.max_size
hibernate.c3p0.max_statements
hibernate.c3p0.min_size
hibernate.c3p0.timeout
它沒有顯示我unreturnedConnectionTimeout和debugUnreturnedConnectionStackTraces屬性,我仍然複製粘貼這兩行,沒有任何效果。我沒有在服務器日誌中隨時獲取debugUnreturnedConnectionStackTraces。
下面是我的hibernate.cfg.xml:
<hibernate-configuration>
<session-factory>
<property name="hibernate.c3p0.unreturnedConnectionTimeout">40</property>
<property name="hibernate.c3p0.debugUnreturnedConnectionStackTraces">true</property>
<property name="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@xyz:1521:sid</property>
<property name="hibernate.connection.username">abc</property>
<property name="hibernate.connection.password">123</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
<property name="hibernate.c3p0.min_size">5</property>
<property name="hibernate.c3p0.max_size">30</property>
<property name="hibernate.c3p0.timeout">20</property>
<property name="hibernate.c3p0.max_statements">50</property>
<property name="hibernate.c3p0.idle_test_period">3000</property>
<property name="hibernate.c3p0.unreturnedConnectionTimeout">40</property>
<property name="hibernate.c3p0.debugUnreturnedConnectionStackTraces">true</property>
</session-factory>
</hibernate-configuration>

剛剛添加的信息C3P0初始化從jboss日誌轉儲到我的問題,沒有得到像unreturnedConnectionTimeout任何關鍵字? 謝謝 –
嗨。請配置爲讓記錄器開始com.mchange。*登錄INFO。這就是c3p0所在的地方。你只有org.hibernate。*這裏。 –
謝謝史蒂夫。你可以請幫忙,如何添加com.mchange。*登錄INFO?還有什麼要添加到我的hibernate.cfg.xml來獲取com.mchange。*日誌。我使用jboss作爲服務器。 –
