基于一个已有的网络工程
拷贝JSF 和支持的jars包到WEB-INF/lib目录
jsf-impl.jar
jsf-api.jar
jstl.jar
standard.jar
配置web.xml以使用Faces Servlet
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>
javax.faces.webapp.FacesServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>
创建faces-config.xml
<?xml version="1.0"?>
<!DOCTYPE faces-config PUBLIC
"-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.0//EN"
"http://java.sun.com/dtd/web-facesconfig_1_0.dtd">
<faces-config>
<navigation-rule>
<from-view-id>/index.jsp</from-view-id>
<navigation-case>
<from-outcome>login</from-outcome>
<to-view-id>/welcome.jsp</to-view-id>
</navigation-case>
</navigation-rule>
</faces-config>
在JSP页面中增加 JSF taglib的引用
<%@taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
创建后台bean
package com.capinfo.bean;
public class UserBean {
private String name;
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
}
后台bean 在JSF controls中注册(faces-config.xml)
<managed-bean>
<managed-bean-name>user</managed-bean-name>
<managed-bean-class>
com.capinfo.bean.UserBean
</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
增加JSF tags使之与后台bean交互
<f:view>
<h:form>
<h3>请输入您的名称</h3>
名称: <h:inputText value="#{user.name}"/><p>
<h:commandButton value="送出" action="login"/>
</h:form>
</f:view>
