1.在Tomcat的server.xml里加入     <Context path="/ttt" docBase="ttt"         debug="5" reloadable="true" crossContext="true">
      <Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"                maxActive="100" maxIdle="30" maxWait="10000"                username="root" password="" driverClassName="com.mysql.jdbc.Driver"                url="jdbc:mysql://localhost:3306/tianyu?autoReconnect=true"/>
     </Context> 2.把mysql的驱动程序导入的项目下的/WEB-INF/lib下,或直接导入到Tomcat的jar包文件里 3./WEB-INF下的web.xml修改成
    <?xml version="1.0" encoding="UTF-8"?>     <web-app version="2.4"     xmlns="http://java.sun.com/xml/ns/j2ee"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee     http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">     <resource-ref>              <description>DB Connection</description>              <res-ref-name>jdbc/TestDB</res-ref-name>              <res-type>javax.sql.DataSource</res-type>              <res-auth>Container</res-auth>     </resource-ref>          <welcome-file-list>        　　<welcome-file>index.jsp</welcome-file>      　　  </welcome-file-list>     </web-app> 4.hibernate.cfg.xml改为
    <?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">
    <!-- Generated by MyEclipse Hibernate Tools.                   --> <hibernate-configuration>
        <session-factory>
            <property name="connection.datasource">java:comp/env/jdbc/TestDB</property>             <property name="show_sql">true</property>             <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
            <!-- Mapping files -->              <mapping resource="com/Student.hbm.xml" />
        </session-factory>
</hibernate-configuration> 5.其他的javabean类和session工厂可以使用自动生成
