Spring视频学习（十二）整合Struts1.3

2009-07-22 15:37 453 查看

1.使用myeclipse来对web添加struts1.3的支持

2.在web容器中实例化spring容器

web.xml如下：

<?xmlversion="1.0"encoding="UTF-8"?>
<web-appxmlns="http://java.sun.com/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"version="2.5"xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<!--1.指定spring的配置文件，默认从web的根目录开始查找，可以通过spring提供的classpath前缀来配置从类路径开始查找-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!--2.对Spring容器进行实例化-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--以上2个步骤即实现了在web容器中实例化spring容器的配置，实例化后放到servletContext里面（Application级别）-->

<!--下面是集成Struts的配置-->
<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>
<init-param>
<param-name>debug</param-name>
<param-value>3</param-value>
</init-param>
<init-param>
<param-name>detail</param-name>
<param-value>3</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!--以上是集成struts的配置，然后在web-inf下配置struts-config.xml-->

</web-app>

3.配置struts-config.xml

（1）新建一个action

packagecom.persia.struts;
/*
*GeneratedbyMyEclipseStruts
*Templatepath:templates/java/JavaClass.vtl
*/
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;
importorg.apache.struts.action.Action;
importorg.apache.struts.action.ActionForm;
importorg.apache.struts.action.ActionForward;
importorg.apache.struts.action.ActionMapping;
importorg.springframework.web.context.WebApplicationContext;
importorg.springframework.web.context.support.WebApplicationContextUtils;

importcom.persia.service.IPersonService;

publicclassPersonListActionextendsAction{

publicActionForwardexecute(ActionMappingmapping,ActionFormform,
HttpServletRequestrequest,HttpServletResponseresponse){

WebApplicationContextctx=WebApplicationContextUtils.getWebApplicationContext(
this.getServlet().getServletContext());
IPersonServiceps=(IPersonService)ctx.getBean("personService");
request.setAttribute("persons",ps.getPersons());

returnmapping.findForward("list");
}
}

（2）配置struts配置文件：

<?xmlversion="1.0"encoding="UTF-8"?>
<!DOCTYPEstruts-configPUBLIC"-//ApacheSoftwareFoundation//DTDStrutsConfiguration1.3//EN""http://struts.apache.org/dtds/struts-config_1_3.dtd">

<struts-config>
<form-beans/>
<global-exceptions/>
<global-forwards/>

<action-mappings>
<actionpath="/person/list"type="com.persia.struts.PersonListAction"validate="false">
<forwardname="list"path="/WEB-INF/page/personlist.jsp"></forward>
</action>
</action-mappings>

<message-resourcesparameter="com.persia.struts.ApplicationResources"/>
</struts-config>

（3）编写personlist.jsp

<%@pagelanguage="java"import="java.util.*"pageEncoding="UTF-8"%>
<%@tagliburi="http://java.sun.com/jsp/jstl/core"prefix="c"%>
<%
Stringpath=request.getContextPath();
StringbasePath=request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPEHTMLPUBLIC"-//W3C//DTDHTML4.01Transitional//EN">
<html>
<head>
<basehref="<%=basePath%>">

<title>PersonList</title>

<metahttp-equiv="pragma"content="no-cache">
<metahttp-equiv="cache-control"content="no-cache">
<metahttp-equiv="expires"content="0">
<metahttp-equiv="keywords"content="keyword1,keyword2,keyword3">
<metahttp-equiv="description"content="Thisismypage">
<!--
<linkrel="stylesheet"type="text/css"href="styles.css">
-->

</head>

<body>
<c:forEachitems="${persons}"var="person">
ID=${person.id},name=${person.name}<br/>
</c:forEach>

</body>
</html>

其中使用了jstl-1.2

4.测试集成

部署时，tomcat6启动出错：

原因是通过myeclipse添加的springaop的支持里面有asm-2.2.3.jar，与hibernate里面的asm.jar冲突，删掉asm-2.2.3.jar就可以了。但是若删掉asm.jar还是会报错的，因此只能删掉asm-2.2.3.jar就OK了。

5.改进--使用依赖注入action

需要四处配置：

（1）applicationContex.xml新加如下：

<!--将Struts的action交给Spring容器来管理-->
<beanname="/person/list"class="com.persia.struts.PersonListAction">
<!--1.这里要求name和struts-config里面的action的path名称一致，因为id不允许有特殊字符-->
<!--2.还得在Struts-config文件里面添加Spring的请求处理器，该处理器会根据action的path属性到Spring容器里面寻找这个bean，若找到了则用这个bean来处理用户的请求-->
<!--3.然后去掉action的type标签和值（可选），当Spring处理器找不到该bean时，才会使用Struts的action-->
<!--4.最后在action里面使用Spring的注入方式来注入业务bean—>

（2）Struts-config.xml如下：

<?xmlversion="1.0"encoding="UTF-8"?>
<!DOCTYPEstruts-configPUBLIC"-//ApacheSoftwareFoundation//DTDStrutsConfiguration1.3//EN""http://struts.apache.org/dtds/struts-config_1_3.dtd">

<struts-config>
<form-beans/>
<global-exceptions/>
<global-forwards/>

<action-mappings>
<actionpath="/person/list"validate="false">
<forwardname="list"path="/WEB-INF/page/personlist.jsp"></forward>
</action>
</action-mappings>

<!--定义Spring的请求处理器，来根据action的path属性到Spring容器里面寻找这个bean，若找到了则用这个bean来处理用户的请求-->
<controller>
<set-propertyproperty="processorClass"value="org.springframework.web.struts.DelegatingRequestProcessor"/>
</controller>
<!--配置完Spring的请求处理器后，去掉action的type属性和值，因为已经交给Spring容器来处理（可选）当Spring处理器找不到该bean时，才会使用Struts的action-->

<message-resourcesparameter="com.persia.struts.ApplicationResources"/>
</struts-config>

（3）PersonListAction如下：

importjavax.annotation.Resource;
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;
importorg.apache.struts.action.Action;
importorg.apache.struts.action.ActionForm;
importorg.apache.struts.action.ActionForward;
importorg.apache.struts.action.ActionMapping;
importorg.springframework.web.context.WebApplicationContext;
importorg.springframework.web.context.support.WebApplicationContextUtils;

importcom.persia.service.IPersonService;

publicclassPersonListActionextendsAction{

@ResourceIPersonServiceps;

publicActionForwardexecute(ActionMappingmapping,ActionFormform,
HttpServletRequestrequest,HttpServletResponseresponse){

//		WebApplicationContextctx=WebApplicationContextUtils.getWebApplicationContext(
//				this.getServlet().getServletContext());
//		IPersonServiceps=(IPersonService)ctx.getBean("personService");

request.setAttribute("persons",ps.getPersons());

returnmapping.findForward("list");
}
}
