在jpaContext.xml中定義了entityManagerFactory bean，但是編譯器拋出錯誤。 提前致謝。

Answer 1

試試這個配置。 並且您的persistence.xml中存在錯誤，請共享該錯誤。

<bean id="hibernateJpaVendorAdapter"
    class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
<bean id="hibernateJpaDialect" class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="com.test.entity" />
    <property name="jpaDialect" ref="hibernateJpaDialect" />
    <property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter" />
    <property name="jpaPropertyMap">
        <map>
            <entry key="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
            <entry key="hibernate.connection.url" value="jdbc:mysql://localhost:3306/online" />
