11、整合SSH框架之添加一个成员

1、我们写一个天机成员的jsp文件

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    
    <title>SSH之人物添加列表</title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->

  </head>
  
  <body>
    <s:form action="Action_add" method="post">
    	名字：<s:textfield name="name" />
    	<input type="submit" value="提交" />
    </s:form>
  </body>
</html>

2、修改Struts.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">
	
<struts>
	<!-- <constant name="struts2.ObjectFactory" value="Spring" /> -->
	<package name="person" namespace="/page" extends="struts-default">
		<action name="Action_*" class="PersonAction" method="{1}">
			<result name="list">/page/personlist.jsp</result>
			<result name="add">/page/addperson.jsp</result>
		</action>
	</package>
</struts>

3、修改action

/**
 * 功能：集成ssh框架
 * author：cutter_point
 * 时间：2015年3月29日17:30:07
 */
package cn.cutter_point.web.action;

import javax.annotation.Resource;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.ServletActionContext;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

import cn.cutter_point.bean.Person;
import cn.cutter_point.service.PersonService;

import com.opensymphony.xwork2.ActionSupport;

public class PersonAction extends ActionSupport 
{
	@Resource private PersonService personService;		//先按名字注入，如果找不到的话就按类型注入
	private String name;	//名字

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	
	public String add() throws Exception
	{
		personService.save(new Person(name));
		
		return "add";
	}

	public String list() throws Exception 
	{
		/*
		//获取实例，方法1
		ServletContext sc = ServletActionContext.getRequest().getSession().getServletContext();
		WebApplicationContext wac = (WebApplicationContext) sc.getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);
		//方法2
		WebApplicationContext webApplicationContext = WebApplicationContextUtils.
													getRequiredWebApplicationContext(ServletActionContext.getServletContext());
		
		if(wac == webApplicationContext)
		{
			System.out.println("ok!!!");
		}
		
		PersonService personService = (PersonService) wac.getBean("personServiceBean");*/
		
		HttpServletRequest  request = ServletActionContext.getRequest();
		
		request.setAttribute("persons", personService.getPersons());
		
		return "list";
	}

}
