一,WEB应用如何使用spring
1,额外jar包。
spring-web-4.0.0.RELEASE.jar,spring-webmvc-4.0.0.RELEASE.jar
2,在web.xml文件中配置监听器,当应用启动时创建IOC对象
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
3,在jsp页面中使用
<%
ApplicationContext context=
WebApplicationContextUtils.getWebApplicationContext(application);
%>
二, spring整合struts2
1,目标:
用spring的IOC容器管理struts2的action
2,步骤:
.同上。(scope必须为 prototype)
<bean class="com.m01.action.PersonAction" id="personAction" scope="prototype"></bean>
.加入struts2
jar包 (另加struts2-spring-plugin-2.3.15.3.jar )
web.xml配置 struts2
<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>
编写struts.xml (class为 bean的 id)
<action name="person-save" class="personAction">
<result>/success.jsp</result>
</action>
