Question

我搜索了所有选项，但现在对我没有任何帮助。我遇到了创建数据库表的问题

线程“ main”中的异常javax.persistence.PersistenceException：名为FinanceiroPU的EntityManager的持久性提供程序没有在javax.persistence.Persistence.createEntityManagerFactory（Persistence.java:61）在javax.persistence.Persistence.createEntityManagerFactory（Persistence.java:39）在com.ronaldosistemas.financeiro.factory.CriaTabelas.main（CriaTabelas.java:9）

这是我的CriaTabelas.Java

package com.ronaldosistemas.financeiro.factory;

import javax.persistence.Persistence;

public class CriaTabelas {

    public static void main(String[] args) {

        Persistence.createEntityManagerFactory("FinanceiroPU");

    }
}

这是我的persistense.xml及其位置

<persistence-unit name="FinanceiroPU">
    <!-- Implementação do JPA, no nosso caso Hibernate -->
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/financeiro" />
        <property name="javax.persistence.jdbc.user" value="root" />
        <property name="javax.persistence.jdbc.password" value="" />
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" />
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true" />
        <property name="hibernate.hbm2ddl.auto" value="update" />
    </properties>
</persistence-unit>

persistence location

最后是我的pom.xml

我关闭了提供程序，并更新了我的sql连接器和休眠持久性jar，但仍然无法正常工作

<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

请有人可以帮助我吗？非常感谢
