用到的jar包有:
commons-beanutils-1.7.0.jar、commons-collections-3.2.jar、commons-fileupload-1.2.1.jar、commons-io-1.3.2.jar、commons-lang-2.3.jar、commons-logging-1.0.4.jar、freemarker-2.3.15.jar、json-lib-2.1.jar、ognl-2.7.3.jar、struts2-core-2.1.8.1.jar、struts2-json-plugin-2.1.8.1.jar、xwork-core-2.1.6.jar
这些包在struts2.1.8的lib文件夹中都有,还需要加上一个ezmorph-1.0.4.jar,本实例中没有用到jsonplugin-0.33.jar包。
一、首先写一个javabean:Person.java
?
package com.leo.bean; public class Person { private String name; private int age; private String sex; private String birthday; public Person(String name, int age, String sex, String birthday) { super(); this.name = name; this.age = age; this.sex = sex; this.birthday = birthday; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public String getBirthday() { return birthday; } public void setBirthday(String birthday) { this.birthday = birthday; } }
?
?二、写Action:ExtjsAction.java
?
package com.leo.action; import java.util.ArrayList; import java.util.List; import com.leo.bean.Person; import com.opensymphony.xwork2.ActionSupport; public class ExtjsAction extends ActionSupport { private long results; private List items; public long getResults() { return results; } public void setResults(long results) { this.results = results; } public List getItems() { return items; } public void setItems(List items) { this.items = items; } public String execute() throws Exception { this.results = 3; Person p1 = new Person("张三", 29, "男", "1990-10-22"); Person p2 = new Person("李四", 28, "男", "1991-03-30"); Person p3 = new Person("王五", 27, "女", "1993-08-17"); this.items = new ArrayList<Person>(); this.items.add(p1); this.items.add(p2); this.items.add(p3); return SUCCESS; } }
?
?三、写配置文件
1.web.xml
?
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>struts2</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <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.struts.xml
?
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <include file="struts-default.xml" /> <package name="json" namespace="/" extends="json-default"> <action name="extjs" class="com.leo.action.ExtjsAction"> <result type="json"></result> </action> </package> </struts>
?
?四、最后写jsp
index.jsp
?
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Ex
