http://prototype.conio.net/dist/
下载(对Ajax支持的prototype--js函数库):
- prototype-1.4.0.js
或 - prototype-1.4.0.tar.gz
http://code.google.com/p/jsonplugin/downloads/list
下载(Struts2的JSON插件):
jsonplugin-0.25.jar | Struts 2 JSON Plugin 0.25 |
第一:手动建立项目结构(类似于MyEclipse创建Web Pro项目的后台操作)
1、新建文件夹结构如下:
Struts2json
|______WEB-INF
|_______classes
|_______src
|_______lib
2、复制Tomcat里conf文件夹里的web.xml到WEB-INF文件夹下,并修改web.xml文件
web.xml文件:
- <?xml version="1.0" encoding="ISO-8859-1"?>
- <web-app 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"
- version="2.5">
- </web-app>
<?xml version="1.0" encoding="ISO-8859-1"?> <web-app 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" version="2.5"> </web-app>
3、将刚才下载解压后Struts2下的lib文件夹里
commons-logging-1.0.4.jar
freemarker-2.3.8.jar
ognl-2.6.11.jar
struts2-core-2.0.11.1.jar
xwork-2.0.4.jar
拷贝到Struts2json下lib文件夹里,并将 jasonplugin-0.25.jar 也拷贝到Struts2json/WEB-INF/lib文件夹下。
将 prototype-1.4.0.js 拷贝到Struts2json文件夹下。
4、找到Strust2里src\apps\showcase\src\main\resources(就是解压后里面的实例)的struts.xml文件复制到Struts2json下classes文件夹下,并修改struts.xml文件 ,或直接在classes文件夹下新建一个
struts.xml文件:
- <?xml version="1.0" encoding="UTF-8" ?>
- <!DOCTYPE struts PUBLIC
- "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
- "http://struts.apache.org/dtds/struts-2.0.dtd">
- <struts>
- </struts>
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> </struts>
5、新建并手写一个build.xml(必须已经安装了Ant工具),并将build.xml放置到WEB-INF文件夹下 (MyEclipse内置了Ant)
build.xml文件:
- <?xml version="1.0"?>
- <project name="struts" basedir="." default="">
- <path id="classpath">
- <fileset dir="lib">
- <include name="*.jar"/>
- </fileset>
- <pathelement path="."/>
- </path>
- <target name="compile" description="Compile all source code">
- <javac destdir="classes" debug="true"
- deprecation="false" optimize="false" failonerror="true">
- <src path="src"/>
- <classpath refid="classpath"/>
- </javac>
- </target>
- </project>
<?xml version="1.0"?> <project name="struts" basedir="." default=""> <path id="classpath"> <fileset dir="lib"> <include name="*.jar"/> </fileset> <pathelement path="."/> </path> <target name="compile" description="Compile all source code"> <javac destdir="classes" debug="true" deprecation="false" optimize="false" failonerror="true"> <src path="src"/> <classpath refid="classpath"/> </javac> </target> </project>
总结:目录结构如下
Struts2t
|______WEB-INF
|_______classes
|______struts.xml
|_______src
|_______lib
|_______ commons-logging-1.0.4.jar
|_______ freemarker-2.3.8.jar
|_______ ognl-2.6.11.jar
|_______ struts2-core-2.0.11.1.jar
|_______ xwork-2.0.4.jar
|_______ jsonplugin-0.25.jar
|_______web.xml
|_______build.xml
|______prototype-1.4.0.js
----------------------------------------------------------
第二:编写核心代码
1、Struts2核心就是控制器,为Struts2添加核心Filter配置在web.xml文件中(拦截所有Web请求并由FilterDispatcher初始化)
web.xml文件:
- <?xml version="1.0" encoding="ISO-8859-1"?>
- <web-app 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"
- version="2.5">
- <filter>
- <filter-name>struts2</filter-name>
- <filter-class>org.apache.Struts2.dispatcher.FilterDispatcher</filter-class>
- </filter>
- <filter-mapping>
- <filter-name>struts2</filter-name>
- <url-pattern>/*</url-pattern>
- </filter-mapping>
- </web-app>
<?xml version="1.0" encoding="ISO-8859-1"?> <web-app 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" version="2.5"> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.Struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
2、编写表现层ajaxtest.jsp页面并放在与WEB-INF同一级目录下。
ajaxtest . jsp文件:
- <%@ page language="java" contentType="text/html; charset=GBK"%>
- <script src="prototype-1.4.0.js" type="text/javascript">
- </script>
- <script language="JavaScript">
- function gotClick()
- {
- //请求的地址
- var url = 'JSONExample.action';
- //将form1表单域的值转换为请求参数
- var params = Form.serialize('form1');
- //创建Ajax.Request对象,对应于发送请求
- var myAjax = new Ajax.Request(
- url,
- {
- //请求方式:POST
- method:'post',
- //请求参数
- parameters:params,
- //指定回调函数
- onComplete: processResponse,
- //是否异步发送请求
- asynchronous:true
- });
- }
- function processResponse(request)
- {
- $("show").innerHTML = request.responseText;
- }
- </script>
- <html>
- <head>
- <title>使用JSON插件</title>
- </head>
- <body>
- <form id="form1" name="form1" method="post">
- <INPUT TYPE="text" name="field1" id="field1"/><br>
- <INPUT TYPE="text" name="field2" id="field2"/><br>
- <INPUT TYPE="text" name="field3" id="field3"/><br>
- <INPUT TYPE="button" value="提交" onClick="gotClick();"/>
- </form>
- <div id="show">
- </div>
- </body>
- </html>
<%@ page language="java" contentType="text/html; charset=GBK"%> <script src="prototype-1.4.0.js" type="text/javascript"> </script> <script language="JavaScript"> function gotClick() { //请求的地址 var url = 'JSONExample.action'; //将form1表单域的值转换为请求参数 var params = Form.serialize('form1'); //创建Ajax.Request对象,对应于发送请求 var myAjax = new Ajax.Request( url, { //请求方式:POST method:'post', //请求参数 parameters:params, //指定回调函数 onComplete: processResponse, //是否异步发送请求 asynchronous:true }); } function processResponse(request) { $("show").innerHTML = request.responseText; } </script> <html> <head> <title>使用JSON插件</title> </head> <body> <form id="form1" name="form1" method="post"> <INPUT TYPE="text" name="field1" id="field1"/><br> <INPUT TYPE="text" name="field2" id="field2"/><br> <INPUT TYPE="text" name="field3" id="field3"/><br> <INPUT TYPE="button" value="提交" onClick="gotClick();"/> </form> <div id="show"> </div> </body> </html>
3、编写POJO(Action)在src下新建文件夹org,在org下新建文件夹jee(这里是建立包名),并新建类JSONExample.java放置在src/org/jee文件夹下。
JSONExample . java文件:
- package org.jee;
- import java.util.HashMap;
- import java.util.Map;
- import com.opensymphony.xwork2.Action;
- import com.googlecode.jsonplugin.annotations.JSON;
- public class JSONExample
- {
- private int[] ints = {10, 20};
- private Map map = new HashMap();
- private String customName = "custom";
- private String field1;
- //'transient'不会被序列化
- private transient String field2;
- //没有setter和getter方法的字段不会被序列化
- private String field3;
- public String execute()
- {
- map.put("name", "yeeku");
- return Action.SUCCESS;
- }
- public String getField1() {
- return field1;
- }
- public void setField1(String field1) {
- this.field1 = field1;
- }
- public String getField2() {
- return field2;
- }
- public void setField2(String field2) {
- this.field2 = field2;
- }
- public String getField3() {
- return field3;
- }
- public void setField3(String field3) {
- this.field3 = field3;
- }
- public int[] getInts() {
- return ints;
- }
- public void setInts(int[] ints) {
- this.ints = ints;
- }
- public Map getMap() {
- return map;
- }
- public void setMap(Map map) {
- this.map = map;
- }
- @JSON(name="newName")
- public String getCustomName()
- {
- return this.customName;
- }
- }
package org.jee; import java.util.HashMap; import java.util.Map; import com.opensymphony.xwork2.Action; import com.googlecode.jsonplugin.annotations.JSON; public class JSONExample { private int[] ints = {10, 20}; private Map map = new HashMap(); private String customName = "custom"; private String field1; //'transient'不会被序列化 private transient String field2; //没有setter和getter方法的字段不会被序列化 private String field3; public String execute() { map.put("name", "yeeku"); return Action.SUCCESS; } public String getField1() { return field1; } public void setField1(String field1) { this.field1 = field1; } public String getField2() { return field2; } public void setField2(String field2) { this.field2 = field2; } public String getField3() { return field3; } public void setField3(String field3) { this.field3 = field3; } public int[] getInts() { return ints; } public void setInts(int[] ints) { this.ints = ints; } public Map getMap() { return map; } public void setMap(Map map) { this.map = map; } @JSON(name="newName") public String getCustomName() { return this.customName; } }
4、在struts.xml里配置Action,修改classes文件
struts.xml文件:
- <?xml version="1.0" encoding="GBK"?>
- <!DOCTYPE struts PUBLIC
- "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
- "http://struts.apache.org/dtds/struts-2.0.dtd">
- <struts>
- <constant name="struts.i18n.encoding" value="UTF-8"/>
- <package name="example" extends="json-default">
- <action name="JSONExample" class="org.jee.JSONExample">
- <result type="json"/>
- </action>
- </package>
- </struts>
<?xml version="1.0" encoding="GBK"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <constant name="struts.i18n.encoding" value="UTF-8"/> <package name="example" extends="json-default"> <action name="JSONExample" class="org.jee.JSONExample"> <result type="json"/> </action> </package> </struts>
注意:
第一:配置
- <constant name="struts.i18n.encoding" value="UTF-8"/>
<constant name="struts.i18n.encoding" value="UTF-8"/>
不使用GBK编码,而使用UTF-8编码,因为Ajax的POST请求都以UTF-8的方式进行编码的。
第二:配置包时,继承了json-default包,不再继承默认的default包,因为只有在json-default包下才有json类型的Result。
5、将Struts2t整个文件夹拷贝到Tomcat/webapps文件夹下
总结:目录结构如下
Struts2t
|______WEB-INF
|_______classes
|______org
|_____jee
|______JSONExample.class
|______struts.xml
|_______src
|______org
|_____jee
|______JSONExample.java
|_______lib
|_______ commons-logging-1.0.4.jar
|_______ freemarker-2.3.8.jar
|_______ ognl-2.6.11.jar
|_______ struts2-core-2.0.11.1.jar
|_______ xwork-2.0.4.jar
|_______ jsonplugin-0.25.jar
|_______web.xml
|_______build.xml
|______prototype-1.4.0.js
|______ajaxtest.jsp
----------------------------------------------------------
三、测试
1、启动Tomcat6
2、http://localhost:8080/struts2t (进行测试)
