Question

我有一个在glassfish 3.1上运行的Web应用程序。我正在使用配置了spring的JPA（Hibernate）。这是我的persistence.xml：

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">
    <persistence-unit name="myPU">

        <class>org.myCompany.entities.Class1</class>

        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" />
            <property name="hibernate.show_sql" value="true" />
        </properties>

    </persistence-unit>
</persistence>

这是我的ApplicationContext.xml的一部分：

<tx:annotation-driven /> 
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"
    p:entityManagerFactory-ref="entityManagerFactory" />

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="jdbc/myDataSource" />
</bean>

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="persistenceUnitName" value="myPU" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="databasePlatform" value="org.hibernate.dialect.MySQL5Dialect" />
        </bean>
    </property>
</bean>

另外我已经在glassfish服务器（jdbc连接池和资源）中声明了我的数据源并且JNDI名称是“jdbc / myDataSource”。问题是我在本地安装的glassfish，通过eclipse的glassfish插件发布，它工作正常但是当我在glassfish的安装上手动部署war文件时（我试过我的VPS - CentOS）然后我收到这个错误：

Error occurred during deployment: Exception while preparing the app : Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: java.sql.SQLException: Connection could not be allocated because: java.net.ConnectException : Error connecting to server localhost on port 1527 with message Connection refused. Error Code: 0. Please see server.log for more details.

由于某种原因，应用程序使用glassfish的默认derby数据源而不是我定义的数据源。有谁知道为什么以及如何克服这个问题？

Answer 1

您是否将JDBC资源配置为使用正确的连接池？配置了默认的derby池。也许您刚刚为您的资源选择了错误的池？

使用jndi与jpa和springfish上的玻璃鱼
