我正在尝试使用 Hibernate 作为提供程序将我的网络应用程序的 JDBC 代码更改为 JPA。我正在使用 Eclipse IDE。我已经定义了一个 MySQL 数据源。我在persistence.xml 中添加了它。但是，我收到以下错误。
6640 [30289364@qtp-7494106-7] ERROR org.hibernate.connection.DatasourceConnectionProvider - Could not find datasource: tamSql

You don't need <non-jta-data-source>when your datasource is configured in <properties>. <non-jta-data-source>is needed when datasource is configured in application server configuration and obtained via JNDI.
你不需要<non-jta-data-source>在你的数据源的配置<properties>。<non-jta-data-source>当数据源在应用服务器配置中配置并通过 JNDI 获取时需要。
