（2）Hibernate配置：
xmlversion="1.0"encoding="UTF-8"?
>
DOCTYPEhibernate-configurationPUBLIC
"-//Hibernate/HibernateConfigurationDTD3.0//EN"
"
—-数据库驱动类名称-->
oracle.jdbc.driver.OracleDriver
—-数据库用户名-->
MY
MY
—-数据库用户密码-->
MY
—-数据库连接字符串-->
jdbc:
oracle:
thin:
@localhost:
1521:
loon
org.hibernate.dialect.Oracle9Dialect
—-控制台是否输出SQL语句-->
true
（3）Spring基本配置：
配置文件应该在WEB-INF/spring/下面
xmlversion="1.0"encoding="UTF-8"?
>
DOCTYPEbeansPUBLIC"-//SPRING//DTDBEAN//EN""http:
//www.springframework.org/dtd/spring-beans.dtd">
—如果用的是XML配置文件，sessionFactory用这个配置"org.springframework.orm.hibernate3.LocalSessionFactoryBean"-->
classpath:
hibernate.cfg.xml
-- 配置多个hibernate.cfg.xml
classpath:
hibernate_admin1.cfg.xml
classpath:
hibernate_admin2.cfg.xml

（4）struts.xml文件的配置：
DOCTYPEstrutsPUBLIC
"-//ApacheSoftwareFoundation//DTDStrutsConfiguration2.0//EN"
"http:
//struts.apache.org/dtds/struts-2.0.dtd">
/resource/json_struts2.jsp
/resource/json_struts2.jsp
3、 建立的项目目录：
Root：
/resource/ext2.0/ 将下载的ext-2.0-beta1.zip文件解压到该目录
/WEB-INF/web.xml
/WEB-INF/lib
/WEB-INF/classes/struts.xml
/WEB-INF/spring/applicationContext.xml
