这只是我的工作总结，其实也算是刚刚搞J2EE吧，所以还算是个新手，可从来都懒的写文章的，现在回头想象总结原来是如此的重要，本文主要描述的是eclipse下整合struts。其实网上这样的文章不知道有多少，但还是希望有兴趣的朋友不仿看看，要是发现有不好的地方的话恳请指正，谢谢！（环境：windows xp+tomcat5.5.28+jdk6+eclipse3.3+myeclipse6）

1 打开eclipse，新建web project。

2 整合struts，右击项目选择myeclipse下的add struts Capabilities。

3 创建一个名为LoginActionForm的ActionForm文件，如下图：

LoginActionForm.java 源代码如下：

/**

*@authorhujun

*@dateMar21,2008

*@fileLoginActionForm.java

*@version1.1

**/

packagecss.web.orc.form;

importorg.apache.struts.action.ActionForm;

publicclassLoginActionFormextendsActionForm{

privatestaticfinallongserialVersionUID=1L;

privateStringuserid;

privateStringpasswd;

privateStringmsg;

publicStringgetUserid(){

returnuserid;

}

publicvoidsetUserid(Stringuserid){

this.userid=userid;

}

publicStringgetPasswd(){

returnpasswd;

}

publicvoidsetPasswd(Stringpasswd){

this.passwd=passwd;

}

publicStringgetMsg(){

returnmsg;

}

publicvoidsetMsg(Stringmsg){

this.msg=msg;

}

在init下创建一个名为LoginAction的Action文件，如下：

/**

*@authorhujun

*@dateMar21,2008

*@fileLoginAction.java

*@version1.1

**/

packagecss.web.orc.action.init;

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;

importcss.web.orc.form.LoginActionForm;

publicclassLoginActionextendsAction{

publicActionForwardexecute(ActionMappingmapping,ActionFormform,

HttpServletRequestrequest,HttpServletResponseresponse){

Stringforward="";

try

{

LoginActionFormloginform=(LoginActionForm)form;

Stringuserid="";

Stringpasswd="";

userid=loginform.getUserid();

passwd=loginform.getPasswd();

if(userid.equals("hujun")&&passwd.equals("123456")){

forward="main";

}

else{

forward="login";

loginform.setMsg("您输入的用户名和密码不正确!");

}

catch(Exceptione){

e.printStackTrace();

}

returnmapping.findForward(forward);

}

4 接下来要在webroot下建两个.jsp文件，分别是login.jsp和main.jsp，代码如下：

<%@pagelanguage="java"%>

<%@pagecontentType="text/html;charset=GBK"%>

<%@tagliburi="/WEB-INF/struts-bean.tld"prefix="bean"%>

<%@tagliburi="/WEB-INF/struts-html.tld"prefix="html"%>

<%@tagliburi="/WEB-INF/struts-logic.tld"prefix="logic"%>

<html>

<body>

<html:formaction="/init/LoginAction.do"method="post">

<tablewidth="50%"align="center"border="0">

<tr>

<tdwidth="100%"align="left">

<fontsize="2"color="red">

</font></td>

</tr>

</table>

<tablewidth="50%"align="center"border="1">

<tr>

<tdwidth="30%"align="right">用户名:</td>

<tdwidth="70%"align="left">

<html:textproperty="userid"maxlength="15"></html:text>

</td>

</tr>

<tr>

<tdwidth="30%"align="right">密码:</td>

<tdwidth="70%"align="left">

<html:textproperty="passwd"maxlength="30"></html:text>

</td>

</tr>

</table>

<tablewidth="50%"align="center"border="0">

<tr>

<tdwidth="50%"align="right"><html:submitvalue="确认"/></td>

<tdwidth="50%"align="left">    <html:resetvalue="重置"/></td>

</tr>

</table>

</html:form>

</body>

</html>

<%@pagelanguage="java"%>

<%@pagecontentType="text/html;charset=GBK"%>

<%@tagliburi="/WEB-INF/struts-bean.tld"prefix="bean"%>

<%@tagliburi="/WEB-INF/struts-html.tld"prefix="html"%>

<%@tagliburi="/WEB-INF/struts-logic.tld"prefix="logic"%>

<html>

<body>

<html:formaction="/init/LoginAction"method="post">

<tablewidth="50%"align="center"border="0">

<tr>

<tdwidth="100%"align="left"><fontsize="5"color="blue"><b>

欢迎您,<bean:writename="LoginActionForm"property="userid"></bean:write>

</b></font></td>

</tr>

</table>

</html:form>

</body>

</html>

5 web.xml文件如下：

<?xmlversion="1.0"encoding="UTF-8"?>

6 struts-config.xml文件如下：
