Question

浏览并尝试了整个Internet的不同解决方案后，我来到这里寻求帮助

我有一个Java项目，在Mac上可以在本地完全正常工作（在本地tomcat上部署），但是当我尝试在Ubuntu服务器上部署相同的战争时，请求将引发500，并显示以下跟踪信息：

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，我不知道这是什么问题。

hera是我 pom.xml 的依赖项

这是放置在src/main/resources/META-INF

上的 persistence.xml

<?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");

任何帮助将不胜感激！

Answer 1

您必须告诉JPA您使用的是哪个JPA提供程序。

将<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>添加到peristence-unit中的persistence.xml中：

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

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

Answer 2

问题是

    <dependency>
        <groupId>javax.persistence</groupId>
        <artifactId>persistence-api</artifactId>
        <version>1.0.2</version>
    </dependency>

正被休眠模式覆盖。我需要删除依赖项或设置与hibernate 5.x兼容的较新版本。

    <dependency>
        <groupId>javax.persistence</groupId>
        <artifactId>javax.persistence-api</artifactId>
        <version>2.2</version>
    </dependency>

我还需要在执行mvn clean之前先发出mvn install命令，然后再进行UPDATE campaign_participants SET first_name = SUBSTRING_INDEX( name, ' ', 1 ) , last_name = IF(SUBSTRING_INDEX( name, ' ', 1 ) != SUBSTRING_INDEX( name, ' ', -1 ), SUBSTRING_INDEX( name, ' ', -1 ), "");生成.war，以便不再缓存依赖项。

----------注意---------

我仍然不清楚为什么它在我的本地计算机（开发此后端的地方）上正常工作

Hibernate-没有名为*的EntityManager持久性提供程序
