SSH整合简单实例
1、配置struts.xml文件:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.action.extension" value="action" />
<package name="s2sh" namespace="/user" extends="struts-default">
<action name="user_*" method="{1}" class="com.java1234.action.UserAction">
<result name="success">/success.jsp</result>
<result name="error">/index.jsp</result>
</action>
</package>
</struts>
2、配置hibernate.cfg.xml文件:
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!--方言-->
<property name="dialect">org.hibernate.dialect.OracleDialect</property>
<!-- 显示sql语句 -->
<property name="show_sql">true</property>
<!-- 自动更新 -->
<property name="hbm2ddl.auto">update</property>
</session-factory>
</hibernate-configuration>
3、配置applicationContext.xml文件
<?xml version="1.0" encoding="UTF-8"?>
