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"?>
