java - 尝试使用 spring 和 hibernate 用户 oracle db 时出错

Question

正如标题中所说，尝试使用以下设置运行我的 spring 应用程序时出现异常:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"

        <property name="url" value="jdbc:oracle:thin:@//[[url]]:[[port]]:[[sid]]" />
        <property name="username" value="username" />
        <property name="password" value="password" />
    </bean>

    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" value="dataSource" />
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
        </property>
        <property name="jpaProperties">
            <map>
                <entry key="hibernate.hbm2ddl.auto" value="validate" />
                <entry key="hibernate.show_sql" value="true" />
            </map>
        </property>
        <property name="packagesToScan" value="com.checkpoint.core.models.entities" />
    </bean>

    <!-- Setup transaction management -->
    <tx:annotation-driven />

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" />

    <context:component-scan base-package="com.checkpoint.core.services.impl" />

</beans>

我得到以下堆栈跟踪:

我是spring开发的新手，可能犯了很多错误

我做错了什么？

Answer 1

改变:

<property name="dataSource" value="dataSource" />

到:

<property name="dataSource" ref="dataSource" />

因为你想引用 bean，而不是 String。
