UnsupportedOperationException - 应用程序必须提供 JDBC 连接

Question

在启动我的休眠/弹簧应用程序时，我收到以下异常：

但是，在查看persistance.xml 时，您可以看到：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
    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">

    <persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name="hibernate.archive.detection" value="class, hbm" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.format_sql" value="true" />

            <property name="javax.persistence.jdbc.driver" value="org.hsqldb.jdbcDriver" />
            <property name="javax.persistence.jdbc.url" value="jdbc:hsqldb:mem:." />
            <property name="javax.persistence.jdbc.user" value="SA" />
            <property name="javax.persistence.jdbc.password" value="" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
            <property name="hibernate.hbm2ddl.auto" value="update" />

        </properties>
    </persistence-unit>

</persistence>

我猜该文件配置正确，用于休眠和 hsql 连接。另一方面是我的applicationContext.xml，如下：

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:security="http://www.springframework.org/schema/security"

    <bean
        class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />

    <bean id="mainWindow" class="com.limitCalculator.gui.MainWindow" />

</beans>

我的问题是，为什么我会得到这个异常？任何建议，什么是错误配置？我个人认为我的applicationContext.xml 不对，但是我不确定错误在哪里。

感谢您的回答！

Answer 1

您应该对您的配置进行以下更改：

在applicationContext.xml

<jdbc:embedded-database id="dataSource" type="HSQL"> <!-- Use this shortcut since you are using HSQL -->
</jdbc:embedded-database>


<bean id="entityManagerFactory"
        class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="persistenceUnitName" value="default" />
        <property name="dataSource" ref="dataSource"/>
</bean>

要让 jdbc 名称规范在 applicationContext.xml 中工作，您需要 添加

xmlns:context="http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd"

和

http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd

到xsi:schemaLocation

然后将您的persistence.xml 更改为

<persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.archive.detection" value="class, hbm" />
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true" />

        <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
        <property name="hibernate.hbm2ddl.auto" value="update" />

    </properties>
</persistence-unit>
