在独立应用程序中使用Hibernate配置JPA时出错

Question

我正在尝试在独立应用程序中使用JPA运行Hibernate。我认为这是一项艰巨的任务。我尝试了很多东西但主要是我失败了。

当我添加日志记录库时，我得到了这个例外：

java.lang.IllegalStateException: slf4j-impl jar is mutually exclusive with log4j-to-slf4j jar (the first routes calls from SLF4J to Log4j, the second from Log4j to SLF4J)

当我删除记录库时，我得到了：

javax.persistence.PersistenceException: Invalid persistence.xml.
Error parsing XML (line-1 : column -1): cvc-elt.1: Cannot find the declaration of element 'persistence'.

我把persistence.xml文件放在int src / META-INF /目录下。该文件的观点：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
             xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            <property name="javax.persistence.jdbc.url" value="jdbc:mysql://127.0.0.1:3306/semantyk"/>
            <property name="javax.persistence.jdbc.user" value="root" />

            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="update" />
        </properties>
    </persistence-unit>
</persistence>

我没有想法了。任何建议都会非常有帮助。 PS。抱歉我的英文。
