struts2day06 自定义结果

类implements Result接口 或者 extends StrutsResultSupport

1.在DateResult.java   implments Result

package com.jsu.struts2.result;

import java.io.PrintWriter;
import java.util.Date;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.ServletActionContext;
import org.apache.struts2.dispatcher.StrutsResultSupport;

import com.opensymphony.xwork2.ActionInvocation;

public class DateResult extends StrutsResultSupport {

	@Override
	public void doExecute(String arg0, ActionInvocation invocation)
			throws Exception {
		Date d = new Date();
		HttpServletResponse response = ServletActionContext.getResponse();
		PrintWriter out = response.getWriter();
		out.print("<center><h1>"+d.toString()+"</h1></center>");
	}

}

 2.写一个Action  DateActio.java

package com.jsu.struts2.action;

import com.opensymphony.xwork2.ActionSupport;

public class DateAction extends ActionSupport{
	@Override
	public String execute() throws Exception {
		return SUCCESS;
	}

}

 3.在strut.xml文件中配置

<?xml version="1.0" encoding="UTF-8" ?>
  <!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"
	"http://struts.apache.org/dtds/struts-2.1.7.dtd">
<struts>
	<package name="resultDemo" namespace="/" extends="struts-default">	
		<!-- 自定义结果声明 -->
		<result-types>
			<result-type name="dateTest" class="com.jsu.struts2.result.DateResult"></result-type>
		</result-types>
		
		<action name="myResult" class="com.jsu.struts2.action.DateAction">
			<result type="dateTest"></result>
		</action>
	</package>
</struts>
