??????JSF的開發(fā),核心是事件驅(qū)動，組件和標(biāo)簽的封裝程度非常高，很多典型應(yīng)用已經(jīng)不需要開發(fā)者去處理http。頁面操作會被自動映射到對應(yīng)的java?bean中，后臺邏輯只需要同java?bean發(fā)生交互。整個過程是通過“依賴注入(DI)”來實現(xiàn)的，其設(shè)計思想與spring相似。
??????下面實例所用的東東包括：Eclipse3.1+MyEclipse4.1,?? tomcat5.0,?? jstl 1.1,? jsf? 。
SayHello 類
package org.cssseek.jsf.model.hello;

public class SayHello {
??? public String say(String name)
??? {
??????? return "你好,"+name;
??? }
}


HelloDelegater 類
package org.cssseek.jsf.control.hello;

import org.cssseek.jsf.model.hello.*;

public class HelloDelegater {
???
??? //------屬性---------
??? private String name;//表單中的文本框數(shù)據(jù)會傳到這里
??? private String result;//web頁會從這里取得運行結(jié)果
??? private SayHello sayHello;//model層的對象,并不事例化,由系統(tǒng)注入
???
??? //-----set/get--------
??? public String getName() {
??????? return name;
??? }
??? public void setName(String name) {
??????? this.name = name;
??? }
??? public SayHello getSayHello() {
??????? return sayHello;
??? }
??? public void setSayHello(SayHello sayHello) {
??????? this.sayHello = sayHello;
??? }
??? public String getResult() {
??????? return result;
??? }
??? public void setResult(String result) {
??????? this.result = result;
??? }
???
??? //-----邏輯方法---------
??? public String say()
??? {
??????? this.setResult(sayHello.say(this.getName()));
??????? return "ok";
