我是靠谱客的博主活力果汁，最近开发中收集的这篇文章主要介绍spring将service注入到Action中(s1和s2)，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

[b][color=red][align=center][size=x-large]spring将service注入到Action中[/size][/align][/color][/b]

[size=x-large][color=green][b]spring与struts1.x集成[/b][/color][/size]
[size=medium][b][color=red]方式一：Action交给spring管理,将业务类注入action[/color][/b][/size]
引入[b][color=green]spring-webmvc-struts.jar包[/color][/b]到lib下，
struts-config.xml配置：



<action name="StudentForm" path="/StudentList"

parameter="actions"

type="org.springframework.web.struts.DelegatingActionProxy">

<forward name="list" path="/userList.jsp"/>

</action>

spring配置applicationContext.xml：



<bean name="/StudentList" class="com.org.momo.action.StudentAction" scope="prototype">

<property name="studentService" ref="studentService" />
	</bean>

[color=red]注意：保持spring配置的bean name和struts配置的action path一致[/color]

StudentAction.java:

private StudentService studentService ;	
public StudentService getStudentService() {

return studentService;
	}
	public void setStudentService(StudentService studentService) {

this.studentService = studentService;
	}

注意：加入上面applicationContext.xml里面的action移到applicationContext-action.xml里面时，
1.需在sturts-config.xml配置applicationContext-action.xml加载路径


	<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">

<set-property property="contextConfigLocation" value="classpath*:applicationContext-struts.xml" />
	</plug-in>

[size=medium][color=red][b]方式二：请求首先交给ActionServlet，然后给org.springframework.web.struts.DelegatingRequestProcessor[/b][/color][/size]，由这个请求处理器根据请求路径从spring容器获取action对象

struts-config.xml:

<action path="/searchAction">

 <!--注意到没有？这里没有配置type属性-->


<forward name="success" path="/result.jsp"/>

</action>

<controller>


<set-property property="processorClass" value="org.springframework.web.struts.DelegatingRequestProcessor"/>

</controller>

spring配置applicationContext.xml：

<bean name="/searchAction" class="com.myproject.action.SearchAction" scope="prototype">

<property name="searchService" ref="searchService"/>
 </bean>

[size=medium][color=red][b]方式三：Action不交给spring管理，直接在Action中实例化应用上下文[/b][/color][/size]，然后通过getBean("xxx")，获取相应业务对象
struts配置struts-config.xml:

<action path="/searchAction"
type="com.myproject.action.SearchAction">


<forward name="success" path="/result.jsp"/>

</action>


<action path="/searchAction"
type="com.myproject.action.SearchAction">

<forward name="success" path="/result.jsp"/>
</action>

对应的Action处理类：

Actionprivate ApplicationContext context=WebApplicationContextUtils.getWebApplicationContext(this.getServlet().getServletContext());

 SearchService searchService=(SearchService)context.getBean("searchService");

private ApplicationContext context=WebApplicationContextUtils.getWebApplicationContext(this.getServlet().getServletContext());
 SearchService searchService=(SearchService)context.getBean("searchService");

[size=x-large][b][color=green]struts2.x与spring集成[/color][/b][/size]
struts.properties 配置

struts.objectFactory=spring
#指定struts的action类实例由spring生成

struts-config.xml配置

<action name="search" class="searchAction" method="searchMax">


<result name="success">/result.jsp</result>


<result name="error">/error.jsp</result>


</action>

spring配置文件applicationContext.xml:

<bean id="searchAction" class="com.myproject.action.SearchAction" scope="prototype">


<property name="searchService" ref="searchService"/>


</bean>


<action name="search" class="searchAction" method="searchMax">

<result name="success">/result.jsp</result>

<result name="error">/error.jsp</result>

</action>
