如果你把數(shù)據(jù)庫(kù)的jar包導(dǎo)入了的話就應(yīng)該看下你用的那個(gè)數(shù)據(jù)庫(kù)了下面是我針對(duì)不同數(shù)據(jù)庫(kù)百度的你先看看

無(wú)法創(chuàng)建請(qǐng)求服務(wù)，后面跟著jdbc環(huán)境問(wèn)題，hibernate的配置文件中關(guān)于數(shù)據(jù)庫(kù)連接和配置的地方有問(wèn)題。
這是連接oracle的代碼
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@172.28.144.110:1521:SHKRP1QA</property>
<property name="hibernate.connection.username">TP</property>
<property name="hibernate.connection.password">PSH#TP</property>

<mapping class="it.robot.po.User_infor"/>

<mapping resource="it/robot/po/user_hbm.xml"/>

</session-factory>
</hibernate-configuration>
這是連接mysql的配置文件代碼

<?xml version="1.0" encoding="GBK" ?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-Configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">
com.mysql.jdbc.Driver
</property>
<property name="hibernate.connection.url">
jdbc:mysql://localhost:3306/shopping
</property>
<property name="hibernate.connection.username">
root
</property>
<property name="hibernate.connection.password">
root
</property>
<property name="dialect">
org.hibernate.dialect.MySQLInnoDBDialect

</property>
<property name="show_sql">true</property>

<mapping resource="Newsss.hbm.xml"/>
</session-factory>

</hibernate-configuration>
其實(shí) 很有可能是你配置文件中沒有配置數(shù)據(jù)庫(kù)方言，你試試配置一下數(shù)據(jù)庫(kù)方言
mysql的方言就是上面代碼中
<property name="dialect">
org.hibernate.dialect.MySQLInnoDBDialect

</property>
