package com.bc.web; import java.util.List; import java.util.Map; import org.apache.struts2.ServletActionContext; import com.bc.bean.InformationParentSheet; import com.bc.dao.impl.daoImpl; import com.bc.service.impl.userServiceImpl; import com.opensymphony.xwork2.ActionContext; import com.opensymphony.xwork2.ActionSupport; public class ListInfoAction extends ActionSupport { private userServiceImpl userService; private daoImpl dao; private List list; public daoImpl getDao() { return dao; } public void setDao(daoImpl dao) { this.dao = dao; } public userServiceImpl getUserService() { return userService; } public void setUserService(userServiceImpl userService) { this.userService = userService; } public List getList() { return list; } public void setList(List list) { this.list = list; } @SuppressWarnings("unchecked") @Override public String execute() throws Exception { // TODO Auto-generated method stub list=userService.pageInfo(1); return SUCCESS; } }

4.说明:

如以下,value="ifRec" 为list下的属性名.另在action内的属性只要提供了get方法,也可以直接在传递的jsp中取.

<s:property value="ifRec"/>
