java - 没有遇到合适的连接提供程序 : JPA Hibernate

Question

我正在尝试使用 root 用户和密码连接到我的本地数据库:password。我只是想学习这些东西，很难开始。我知道需要为 entitymanager 和交易系统提供一个连接，但我想我已经在我的持久性文件中指定了。最后，我正在运行独立的 jboss，所以也许我还需要配置服务器端，但我觉得一切都应该在我的容器中配置。最后，我没有 hibernate.cfg.xml 文件，因为所有内容都为我的实体添加了注释。

<?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="persistenceUnit"
        transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
            <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/hello" />
            <property name="javax.persistence.jdbc.user" value="root" />
            <property name="javax.persistence.jdbc.password" value="password" />
            <property name="hbm2ddl.auto" value="create" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
        </properties>
    </persistence-unit>
</persistence>

Answer 1

根据我的经验，我可以说出一些事情:

1. 我没用过<provider>标签或 hibernate.dialect属性(property)曾经，这可能是个问题。
2. 我从未使用过其他属性 比hibernate.something.something或应用程序服务器特定的标签，如 jboss.something.something在 persistence.xml .您正在使用不同的 属性的“家族”，这可能是个问题。
3. 更多基本提示 - 有助于了解您的环境。应用服务器(Tomcat、JBoss等)、Java版本等。
