1、新建dynamic web project，选择configuration，如图所示：
2、新建之后，显示如下：
3、创建MyJsfAction.javapackage com.dw.action;import javax.faces.event.ValueChangeEvent;public class MyJsfAction { private String type; public String getType() { return type; } public void setType(String type) { this.type = type; } // 定义监听值改变的方法 public void selectType(ValueChangeEvent event){ String nameTemp = (String)event.getNewValue(); if("JAVA".equals(nameTemp)){ type = "JAVA"; }else{ type = "C"; } } public String gourl(){ return type; }}
4、新建userChoose.jsp<%@ page language="java" import="java.util.*" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%><%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><title>My JSF 'userChoose.jsp' starting page</title></head><body> JSF测试信息！ <br/> <f:view> <h:form> 请选择查询项目：<br /> <h:selectOneMenu value="#{dw.type}" valueChangeListener="#{dw.selectType}" id="selecttype"> <f:selectItem itemValue="JAVA" itemLabel="JAVA" /> <f:selectItem itemValue="C" itemLabel="C" /> </h:selectOneMenu> <h:commandButton value="提交" action="#{dw.gourl}"> </h:commandButton> </h:form> </f:view></body></html>
5、新建newJava.jsp<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %><%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><title>My JSP 'newJava.jsp' starting page</title></head><body> JSF测试信息！<br/> <f:view> <h:form> 欢迎学习<h:outputText value="#{dw.type}"></h:outputText>语言，祝你成功！<br/> </h:form> </f:view></body></html>
6、新建newC.jsp<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %><%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><title>My JSP 'newC.jsp' starting page</title></head><body> JSF测试信息！<br/> <f:view> <h:form> 欢迎学习<h:outputText value="#{dw.type}"></h:outputText>语言，祝你成功！<br/> </h:form> </f:view></body></html>
7、修改配置文件faces-config.xml<?xml version="1.0" encoding="UTF-8"?><faces-config 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-facesconfig_1_2.xsd" version="1.2"><!-- 配置托管Bean --> <managed-bean> <managed-bean-name>dw</managed-bean-name> <managed-bean-class>com.dw.action.MyJsfAction</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean><!-- 定义导航规则与页面 --> <navigation-rule> <from-view-id>/userChoose.jsp</from-view-id> <navigation-case> <from-outcome>JAVA</from-outcome> <to-view-id>/newJava.jsp</to-view-id> </navigation-case> <navigation-case> <from-outcome>C</from-outcome> <to-view-id>/newC.jsp</to-view-id> </navigation-case> </navigation-rule></faces-config>
8、修改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" id="WebApp_ID" version="2.5"> <display-name>FirstJSFTestProject</display-name> <listener> <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class> </listener> <!-- 配置JSF的配置文件 --> <context-param> <param-name>javax.faces.CONFIG_FILES</param-name> <param-value>/WEB-INF/faces-config.xml</param-value> </context-param> <!-- 处理请求的servlet --> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>0</load-on-startup> </servlet> <!-- 配置所有.jsf结尾的请求都由JSF处理 --> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.jsf</url-pattern> </servlet-mapping></web-app>
9、Run on server,浏览器访问http://localhost:8080/FirstJSFTestProject/userChoose.jsf（否则，会报错!）
10、项目的代码结构如图所示：
11、Jar下载链接：http://archive.apache.org/dist/jakarta/taglibs/standard/binaries/
