Java Hibernate驱动程序类配置，指示默认属性和类

基本上，我想知道为什么它试图加载org.h2.Driver，即使我没有使用它，并因此抛出错误。 其次，当我指定了一个连接池时，为什么它使用内置连接池

下面是我的配置文件的一个片段

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="connection.datasource">jdbc/MobicareDB</property>

        <property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>

        <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
        <property name="current_session_context_class">thread</property>
        <property name="show_sql">true</property>
        <property name="use_sql_comments">true</property>
        <property name="generate_statistics">true</property>

你找到解决办法了吗？没有，所以我选择了一个早期的版本，看起来效果不错
