本文详细介绍了JavaWeb开发中使用Spring、Hibernate和Struts框架进行整合配置的方法，包括struts1的web.xml配置、Spring与hibernate的配置，以及如何在三个spring文件中细分配置，以实现更清晰的操作，以帮助开发者更好地理解和应用这些框架。

java web 开发中常用的　框架　就是　，struts 1 ,hibernate ,spring 整合，
在这里把它贴出来，经常忘记，加深一下印象。

首先配置基本的　struts 1
web.xml 配置方式如下，先加上这个配置：

<servlet>
        <servlet-name>action</servlet-name>
        <servlet-class>
            org.apache.struts.action.ActionServlet
        </servlet-class>
        <init-param>
            <param-name>config</param-name>
            <param-value>/WEB-INF/struts-config.xml</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>action</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
下面是spring 与 hibernate，
这个与hibernate 配置，细分成了三个spring文件,看起来更加清晰。
先在web.xml 加入这个配置：

    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            /WEB-INF/config/spring-basic-Context.xml,
            /WEB-INF/config/spring-dao-Context.xml,
            /WEB-INF/config/spring-services-Context.xml
        </param-value>
    </context-param>

下面分别是三个spring 配置，，简单的book操作，做个例子。

以上配置完，都是依赖注入。这些框架的配置都差不多。主要还是根据实际的业务来加其他的组件进去。
