使用struts2代替servlet开发j2ee,快速搭建struts2开发环境

最近在开发一个简单的jsp企业网站，由于使用jsp+servlet配置servlet比较麻烦所以决定使用struts2框架代替servlet,下面是快速搭建一个struts2开发框架的步骤

1.加入struts2的jar,所需的基本jar如下图，后面开发如果还需要添加则加上就是



2.在web.xml里配置struts2的filter,如下图



3.在src下建一个struts.xml的配置文件，该文件是访问路径的配置文件 源码如下：

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

<constant name="struts.action.extension" value="do"></constant>

<constant name="struts.devMode" value="true" />

<package name="com" namespace="" extends="struts-default">

<action name="doPhotoList" method="doPhotoList" class="com.action.CompanyPhotoAction" />

<action name="doPhotoListByPage" method="doPhotoListByPage" class="com.action.CompanyPhotoAction">

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

</action>

<action name="doNewsListByPage" method="doNewsListByPage" class="com.action.NewCenterAction">

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

</action>

<action name="doCustomerReq" method="doCustomerReq" class="com.action.CustomerReqAction" />

</package>

</struts>

----------------------------------------------------------------------------------

<constant name="struts.action.extension" value="do"></constant> 设置访问后缀为.do ,struts2默认的访问后缀是.action

3.开发一个action,有三种实现方式

a.一个普通的javaBean

b.实现Action接口

c.继承ActionSuport类 建议使用

代码：

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import net.sf.json.JSONArray;

import org.apache.struts2.ServletActionContext;

import com.entity.CompanyPhotoVo;

import com.service.impl.CompanyPhotoServiceImpl;

import com.service.inf.ICompanyPhotoService;

import com.util.page.Page;

import com.opensymphony.xwork2.ActionSupport;

/**

* 公司相册控制类

* @author xm

*

*/

public class CompanyPhotoAction extends ActionSupport {

private static final long serialVersionUID = 1L;

private ICompanyPhotoService companyPhotoServiceImpl = new CompanyPhotoServiceImpl();

private Integer pageNo;

private Integer pageSize;

public Integer getPageNo() {

return pageNo;

}

public void setPageNo(Integer pageNo) {

this.pageNo = pageNo;

}

public Integer getPageSize() {

return pageSize;

}

public void setPageSize(Integer pageSize) {

this.pageSize = pageSize;

}

/**

* 查询公司图集-可分页

* @return

*/

public String doPhotoListByPage(){

HttpServletRequest request = ServletActionContext.getRequest();

Page<CompanyPhotoVo> page = new Page<CompanyPhotoVo>();

try {

page = companyPhotoServiceImpl.doCompanyPhotoList(pageNo, pageSize);

} catch (Exception e) {

e.printStackTrace();

}

request.setAttribute("page", page);

return "success";

}

}

4.jsp页面展示（带有分页）

<!--图集 开始-->

<div class="content">

<div class="cmain" id="gallery">

<ul>

<s:iterator value="#request.page.list" var="photo">

<li>

<a href="photos/<s:property value='#photo.bigPath' />" title="">

<img src="photos/<s:property value='#photo.smallPath' />" alt="" />

</a>

</li>

</s:iterator>

</ul>

</div>

<div class="page">

<div class="p-page">

<form id="pageForm" name="" method="post" action="<%=path %>/doPhotoListByPage.do">

<input type="hidden" id="hPageNo" name="pageNo" value="<s:property value='#request.page.pageNo' />"/>

<input type="hidden" id="hPageSize" name="pageSize" value="<s:property value='#request.page.pageSize' />"/>

<input type="hidden" id="hTotalPage" value="#request.page.getTotalPage()"/>

<div><input type="button" name="" class="page-up" value="" onclick="choosePage('page-up')"/></div>

<s:bean name="org.apache.struts2.util.Counter" id="counter">

<s:param name="first" value="1" />

<s:param name="last" value="#request.page.getTotalPage()" />

<s:iterator var="count">

<s:if test="#count == #request.page.pageNo">

<div><input type="button" name="" class="inputfocus" value="<s:property value="#count"/>" /></div>

</s:if>

<s:else>

<div><input type="button" name="" class="page-no" value="<s:property value="#count"/>" onclick="choosePage(<s:property value='#count'/>)"/></div>

</s:else>

</s:iterator>

</s:bean>

<div><input type="button" name="" class="page-down" value="" onclick="choosePage('page-down')"/></div>

</form>

</div>

</div>

</div>

<!--图集 结束-->
