struts2.2 项目搭建 以及与 struts2-json jquery 前后台进行交互

1.新建web项目 引人10个jar包（在附件中下载），名称如下
commons-fileupload-1.2.2.jar 
commons-io-2.0.1.jar
commons-logging-1.1.1.jar
commons-lang3-3.1.jar
commons-lang-2.5.jar
freemarker-2.3.16.jar
ognl-3.0.1.jar
struts2-core-2.2.3.jar
xwork-core-2.2.3.jar
javassist-3.12.0.GA.jar

2.在src下 新建一个struts.xml 内容如下：

<?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>
	<constant name="struts.action.extension" value="html" />
	<package name="sysdefault" extends="struts-default" abstract="true">
		<result-types>
			<result-type name="json" class="org.apache.struts2.json.JSONResult"/>
		</result-types>
		<interceptors>
			<interceptor-stack name="mystack">
				<interceptor-ref name="defaultStack" >
					<param name="exception.logEnabled">true</param>
            		<param name="exception.logLevel">error</param>					
				</interceptor-ref>
			</interceptor-stack>
			<interceptor name="json" class="org.apache.struts2.json.JSONInterceptor"/>
		</interceptors>
		<default-interceptor-ref name="mystack" />
	</package>
	
	<package name="zzghj_msg_test" extends="sysdefault">
		<action name="company" class="com.trt.CompanyAction" > 
			<result name="json" type="json"><param name="includeProperties">msg</param></result>
			<result name="index" >index.jsp</result>
		</action>
	</package>
</struts>

3.在web.xml配置  StrutsPrepareAndExecuteFilter，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
	xmlns="http://java.sun.com/xml/ns/j2ee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
    <filter>
		<filter-name>struts2</filter-name>
		<filter-class>
			org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
		</filter-class>
	</filter>
	
	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
</web-app>

4.CompanyAction.java

/**
 * 
 */
package com.trt;

import org.xvolks.jnative.JNative;
import org.xvolks.jnative.Type;
import org.xvolks.jnative.exceptions.NativeException;

/**
 * @author Administrator
 *
 */
public class CompanyAction  extends AbstractAction{

	public String toIndex(){
		System.out.println("to index.jsp");
		return "index";
	}
	
	private String msg;
	public String testmsg() {
		String dport = paraPool.get("dport");
		String dpaud = paraPool.get("dpaud");
		String dphone = paraPool.get("dphone");
		System.out.println("dport:"+dport);
		System.out.println("dpaud:"+dpaud);
		System.out.println("dphone:"+dphone);
		JNative n = null;
		try {
			n = new JNative("mysms.dll", "InitModem");
			n.setRetVal(Type.INT);
			int i = 0;
			n.setParameter(i++, dport);
			n.setParameter(i++, dpaud);
			n.invoke();
			System.out.println(n.getRetValAsInt());
			String res = n.getRetVal();
			System.out.println("启动服务-返回结果："+res);
			
			
			n = new JNative("mysms.dll", "SendSms");
			n.setRetVal(Type.INT);
			int j = 0;
			n.setParameter(j++, dport);
			n.setParameter(j++, dpaud);
			n.setParameter(j++, "Hello Wold");
			n.setParameter(j++, dphone);
			n.setParameter(j++, "FALSE");
			n.setParameter(j++, "FALSE");
			n.setParameter(j++, "FALSE");
			n.invoke();
			
			String res2 = n.getRetVal();
			System.out.println("发送结果："+res2);
			msg = "启动结果：" + res + ",发送结果：" + res2;
		} catch (Exception e1) {
			System.out.println("启动服务出错了！");
			e1.printStackTrace();
			if (n != null) {
				try {
					n.dispose();// 释放资源
				} catch (NativeException e) {
					e.printStackTrace();
				} catch (IllegalAccessException e) {
					e.printStackTrace();
				}
			}
			msg = "error";
			return JSON;
		}
		return JSON;
	}
	public String getMsg() {
		return msg;
	}
	public void setMsg(String msg) {
		this.msg = msg;
	}
	
	
}

5.配置完后 直接访问：
http://localhost:8080/zzmsg/company!toIndex.html

如果能正常访问 ，恭喜你 struts2.2你已经配置成功了


如果想用jquery 的 json 前后台进行交互 ，还需要引人一个包
struts2-json-plugin-2.3.15.1.jar

如此你的jsp就可以这样写：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%
	String baseurl = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+request.getContextPath()+"/";
%>
<c:set var="basepath" value="<%=request.getContextPath()%>" />
<c:set var="baseurl" value="<%=baseurl%>" />
