struts2开发实例

本次开发的struts2实例是部署在jboss5.1.0中，先介绍下 jboss的基本配置

1.jdk的基本配置肯定要有，这里就不说了

2.新建环境变量JBOSS_HOME,值为jboss所在的目录

3.编辑PATH环境变量，添加%JBOSS_HOME%\bin;

4.JBOSS加载的默认配置是jboss-5.1.0.GA\server\default\deploy\jbossweb.sar下的server.xml，所以要修改端口要在该文件下修改，我将端口修改为了8090

再介绍下myeclipse配置jboss，这里用的是myeclipse6.5,直接上图

配置JDK

下面开始用struts2进行开发

struts2应用的开发步骤

*引入jar包：

commons-fileupload-1.3.1.jar

commons-io-2.2.jar

commons-lang3-3.1.jar

commons-logging-1.1.3.jar

freemarker-2.3.19.jar

javassist-3.11.0.GA.jar

log4j-api-2.0.jar

log4j-core-2.0.jar

ognl-3.0.6.jar

struts2-core-2.3.16.3.jar

xwork-core-2.3.16.3.jar

* 在web.xml文件中的核心filter来拦截用户请求

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5"

xmlns="http://java.sun.com/xml/ns/javaee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<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>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

</web-app>

* 定义处理用户请求的action类

package com.jiangxl.ssh.web;

import java.io.PrintWriter;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.commons.logging.Log;

import org.apache.commons.logging.LogFactory;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {

private static final Log log = LogFactory.getLog(LoginAction.class);

@Override

public String execute() throws Exception {

HttpServletRequest request = ServletActionContext.getRequest();

HttpServletResponse response = ServletActionContext.getResponse();

String userName = request.getParameter("userName");

String password = request.getParameter("password");

log.info("userName："+userName+"\n"+"password:"+password);

PrintWriter writer = response.getWriter();

writer.write("1");

return null;

}

* 配置action

从struts2提供的例子中拷贝一个struts.xml放在classpath路径下，配置自己的action

<?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">

<default-action-ref name="index" />

<global-results>

<result name="error">/error.jsp</result>

</global-results>

<global-exception-mappings>

<exception-mapping exception="java.lang.Exception" result="error"/>

</global-exception-mappings>

<param name="actionName">HelloWorld</param>

<param name="namespace">/example</param>

</result>

</action>

</package>

<global-results>

<result name="error">/error.jsp</result>

</global-results>

<result name="success">/example/success.jsp</result>

</action>

</package>

</struts>

* 编辑视图资源

新建一个login.jsp页面，我引入了jquery来写的页面

<%@ page language="java" contentType="text/html; charset=GBK" pageEncoding="GBK"%>

<html>

<head>

<body>

<table>

</tr>

</table>

</fieldset>

</div>

</body>

</html>

function doLogin(){

var userName =$("#userName").val();

var password = $("#password").val();

var param = {"userName":userName,"password":password};

$.ajax({

url:'example/login.action', //action的name 是login, namespace="/example"

data:param,

type:'POST',

dataType:'json',

success:function(data,textStatus,jqXHR){

alert(data);

}

});

}

function cancel(){

}

</script>

这样，一个简单的基于struts的web工程就搭建好了

通过myeclipse部署到jboss，在ie下输入对应url就可以访问了。
