這是我的 c3p00l 配置

 <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
  <!--  <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
     <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >  -->
        <property name="driverClass"><value>${jdbc.driverClassName}</value></property> 
        <property name="jdbcUrl"><value>${jdbc.url}</value></property>
        <property name="user"><value>${jdbc.username}</value></property>
        <property name="password"><value>${jdbc.password}</value></property>
    </bean>

我該如何解決這個問題，這個問題是否與 c3pool 相關。我正在使用具有默認值的 c3pool，我是否需要指定任何 c3pool 屬性

Answer 1

你試過這個嗎？

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
    <property name="driverClass"><value>${jdbc.driverClassName}</value></property> 
    <property name="jdbcUrl"><value>${jdbc.url}</value></property>
    <property name="user"><value>${jdbc.username}</value></property>
    <property name="password"><value>${jdbc.password}</value></property>
    <property name="validationQuery" value="SELECT 1"/>
    <property name="testOnBorrow" value="true"/>
</bean>

Answer 2

這可以指定與數據庫問題的連接（可能像描述的過時的連接在這里

一般來說，除了異常本身之外，這里沒有太多信息，我只需在 JDBCTransaction class 處放置一個斷點，看看它為什么會失敗。

希望這可以幫助

Answer 3

我使用以下配置收到此錯誤：

@PersistenceContext(type=PersistenceContextType.EXTENDED)  
@Autowired
private EntityManager entityManager;

我沒有意識到 PersistenceContextType.EXTENDED 不是線程安全的。 我相信這個錯誤一定是由多個用戶訪問應用程序和線程沒有被安全管理引起的。 當我將配置更改為以下內容時，刪除 PersistenceContextType.EXTENDED 部分：

@PersistenceContext
@Autowired
private EntityManager entityManager;

...然后錯誤停止發生在我身上。
