我正在尝试运行我的项目，但出现以下错误：

WARN : org.hibernate.ejb.HibernatePersistence - HHH015016: Encountered a deprecated javax.persistence.spi.PersistenceProvider [org.hibernate.ejb.HibernatePersistence]; use [org.hibernate.jpa.HibernatePersistenceProvider] instead.
WARN : org.hibernate.engine.jdbc.internal.JdbcServicesImpl - HHH000342: Could not obtain connection to query metadata : Communications link failure

所以我们必须看看我的 applicationContext.xml 文件，它看起来如下：

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

    <bean id="entityManagerFactory"

    <bean id="transactionManager"

        </property>
    </bean>
    <tx:annotation-driven transaction-manager="transactionManager"/>
    <context:annotation-config></context:annotation-config>
</beans>

persence.xml 看起来如下：

<?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"

    version="2.0">
    <persistence-unit name="MY_P_U" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.hbm2ddl.auto" value="create" />
<!--            <property name="eclipselink.ddl-generation" value="create-tables" /> -->

        </properties>
    </persistence-unit>
</persistence>

我认为信息很明确：

Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set

您必须在此处添加方言：

<provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.hbm2ddl.auto" value="create" />
<!--            <property name="eclipselink.ddl-generation" value="create-tables" /> -->

        </properties>

到您的数据库 SQL 方言。
