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";
}
}
4、好的，我们接下来看看效果
开始的时候数据库中
我们插入一个数据
我们点击提交
结果显示出来了！！！！！
好吧，那就结束吧，恩！你没看错，就是结束了，为什么？？因为没有出现乱码！！！
我是想出现中文乱码问题那就解决一下，看看如何解决的，但是它不出现，我们不能强迫他，恩，结束了！！！！
