java - Hibernate - 没有名为 * 的 EntityManager 的 presistence 提供程序

问题描述

在互联网上浏览并尝试了不同的解决方案后，我来这里寻求帮助

我有一个在 Mac 上本地运行良好的 java 项目（部署在本地 tomcat 上），但是当我尝试在 Ubuntu 服务器上部署相同的战争时，请求抛出 500 并带有以下跟踪：

javax.servlet.ServletException: javax.persistence.PersistenceException: No Persistence provider for EntityManager named PERSISTENCE: Provider named org.hibernate.jpa.HibernatePersistenceProvider threw unexpected exception at create EntityManagerFactory:

老实说，我不知道这里有什么问题。

hera 是我的pom.xml的依赖项

    </dependencies>

这是放置在src/main/resources/META-INF

<?xml version="1.0" encoding="UTF-8" ?>
<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" xmlns="http://java.sun.com/xml/ns/persistence">

    <persistence-unit name="PERSISTENCE" transaction-type="RESOURCE_LOCAL">
        <properties>
            <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
            <property name="javax.persistence.jdbc.url"
                      value="jdbc:mysql://localhost/name?useSSL=false"/>
            <property name="javax.persistence.jdbc.user" value="usr"/>
            <property name="javax.persistence.jdbc.password" value="pwd"/>

            <property name="hibernate.show_sql" value="true"/>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
                <property name="hibernate.hbm2ddl.auto" value="create" />
        </properties>
    </persistence-unit>

</persistence>

这就是我实例化 EntityManagerFactory 的方式

if (emf == null)
            emf = Persistence.createEntityManagerFactory("PERSISTENCE");

任何形式的帮助将不胜感激！

解决方案

您必须告诉JPA您正在使用哪个 JPA 提供程序。

添加<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>到您peristence-unit的输入persistence.xml：

<persistence-unit name="PERSISTENCE" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

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