ClassNotFoundException for HibernatePersistenceProvider

Question

我有一个JSF项目，它使用java 7完美地构建，但是当我试图在中部署WAR时，我得到了下面的错误。

JBoss版本为7.1.1最终版本

我在这里做错什么了？

Answer 1

这里的问题是JBoss模块中的Hibernate jars与我的项目之间的冲突。当我使用JBoss最新版本(WildFly 20)时，问题就消失了。注意，我必须将MySQL连接器jar复制到WildFly部署dir中，并将以下数据源添加到我的项目中。

<datasources xmlns="http://www.jboss.org/ironjacamar/schema">
    <datasource jndi-name="MySQLDS" pool-name="MySQLPool">
        <connection-url>jdbc:mysql://localhost:3306/db</connection-url>
        <driver>mysql-connector-java-8.0.21.jar</driver>
        <pool>
            <max-pool-size>30</max-pool-size>
        </pool>
        <security>
            <user-name>username</user-name>
            <password>password</password>
        </security>
    </datasource>
</datasources>
