SSH框架基础知识及搭建步骤

1、基于struts2，spring3，Hibernate3

2、SSH对应 struts spring hibernatestruts 采用MVC模式，主要是作用于用户交互

     spring 采用IOC和AOP~作用比较抽象，是用于项目的松耦合

     hibernate 是对象持久化框架，其实就是实体类和数据库表建立关系，操作类就会触发相应的sql语句，可以不用写任何sql语句，完成数据库编

使用步骤

1、首先分别搭建三个框架，先配置struts

          (1)、加入以下jar包  到lib

freemarker-2.3.15.jar
858.7 KB

commons-io-1.3.2.jar
85.7 KB

xwork-core-2.1.6.jar
1.5 MB

ognl-2.7.3.jar
234.2 KB

commons-fileupload-1.2.1.jar
56.4 KB

ojdbc6.jar
1.9 MB

struts2-core-2.1.8.1.jar
738.4 KB

          (2)、拷贝已有的struts.xml到src,

struts.xml
600 bytes

          (3)、拷贝已有web.xml文件,配置web.xml中和Struts2 相关的配置，配置拦截器

     <filter>

          <filter-name>struts2</filter-name>

          <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

     </filter>

     <filter-mapping>

          <filter-name>struts2</filter-name>

          <url-pattern>/*</url-pattern>

     </filter-mapping>

     <listener>

 

2、配置Hibernate

          (1)、拷贝jar包到lib

                    《1》核心包一个

hibernate3.jar
4.0 MB

                    《2》

ojdbc14.jar
1.5 MB

javassist-3.12.0.GA.jar
618.5 KB

antlr-2.7.6.jar
433.0 KB

dom4j-1.6.1.jar
306.5 KB

slf4j-api-1.6.1.jar
24.9 KB

commons-collections-3.1.jar
546.3 KB

jta-1.1.jar
10.6 KB

          

          (2)、拷贝已有hibernate.cfg.xml文件到src目录下

                    

hibernate.cfg.xml
999 bytes

               内容如下

<!DOCTYPE hibernate-configuration PUBLIC

     "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

     "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<!--      1、加载数据库驱动，获取数据库连接 -->

     <session-factory>

          <property name="hibernate.dialect">org.hibernate.dialect.Oracle9iDialect</property>

          <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>

          <property name="hibernate.connection.username">scott</property>

          <property name="hibernate.connection.password">tiger</property>

          <property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property><!-- 169.254.146.196 -->

          <!-- 显示SQL，默认为false -->

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

          <!-- 添加一个映射文件  与具体的Java类有关-->

           <mapping resource="com/ldl/bean/user.hbm.xml"/>

           <mapping resource="com/ldl/bean/role.hbm.xml"/>

     </session-factory>

</hibernate-configuration>

3、配置Spring

               (1)、加载jar包到lib

commons-logging.jar
59.4 KB

org.springframework.aop-3.0.7...
313.9 KB

aspectjrt.jar
112.2 KB

cglib-nodep-2.1_3.jar
316.6 KB

org.springframework.jdbc-3.0....
377.0 KB

org.springframework.context-3...
654.7 KB

org.springframework.core-3.0....
374.6 KB

org.springframework.expressio...
165.8 KB

org.springframework.transacti...
226.6 KB

aspectjweaver.jar
1.5 MB

aopalliance.jar
4.4 KB

org.springframework.asm-3.0.7...
51.8 KB

org.springframework.aspects-3...
34.5 KB

          (2)、配置applicationContext.xml以及applicationContext.xml

               

applicationContext_jdbc.xml
1.5 KB

applicationContext.xml
1.0 KB

4.整合spring和struts，目的：Action交由spring管理

 

<listener>

          <listener-class>

               org.springframework.web.context.ContextLoaderListener

          </listener-class>

     </listener>

                          

<context-param>

          <param-name>contextConfigLocation</param-name>

          <param-value>

              classpath:applicationContext.xml,

              classpath:applicationContext_jdbc.xml

          </param-value>

     </context-param>
