Question

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也抛出错误。
其次，当我指定连接池时，它会使用内置连接池。

这是我的配置文件的片段

<?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>

还有一个片段应用程序部署期间的控制台
