JSF
1.导入jar文件 从MyEclipse->lib文件夹中
自动生成web-info下生成配置文件myface-config.xml 并配置
web.xml的自动配置
2.创建login.jsp 选择 default jsf template 模板
success.jsp
3.在src 创建包com.test.backingbean 及UserBean.java(backingbean包的后缀名规范)
启动tomcat服务器 http://localhost:8080/test/login.faces 不是login.jsp (login.faces显示页面标签)
自动生成web-info下生成配置文件myface-config.xml 并配置
<?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"> <managed-bean> <managed-bean-name>userBean</managed-bean-name> <managed-bean-class>com.test.backingbean.UserBean</managed-bean-class> <managed-bean-scope>request</managed-bean-scope> </managed-bean> <navigation-rule> <from-view-id>/login.jsp</from-view-id> <navigation-case> <from-outcome>success</from-outcome> <to-view-id>/success.jsp</to-view-id> </navigation-case> <navigation-case> <from-outcome>failure</from-outcome> <to-view-id>/login.jsp</to-view-id> </navigation-case> </navigation-rule> </faces-config>
web.xml的自动配置
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.faces</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
2.创建login.jsp 选择 default jsf template 模板
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
</head>
<body>
<f:view>
<h1>Login Page</h1>
<b><h:outputText value="#{userBean.message}"></h:outputText></b>
<h:form>
<h:outputText value="username: "></h:outputText>
<h:inputText value="#{userBean.username}"></h:inputText> <br>
<h:outputText value="password: "></h:outputText>
<h:inputSecret value="#{userBean.password}"></h:inputSecret> <br>
<h:commandButton value="Login" action="#{userBean.validateUser}"></h:commandButton>
</h:form>
</f:view>
</body>
</html>
success.jsp
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

</head>
<body>
<f:view>
<h:outputText value="username: "></h:outputText>
<h:outputText value="#{userBean.username}"></h:outputText> <br>
<h:outputText value="password: "></h:outputText>
<h:outputText value="#{userBean.password}"></h:outputText>
</f:view>
</body>
</html>
3.在src 创建包com.test.backingbean 及UserBean.java(backingbean包的后缀名规范)
package com.test.backingbean;
public class UserBean
{
private String username;
private String password;
private String message;
public String getUsername()
{
return username;
}
public void setUsername(String username)
{
this.username = username;
}
public String getPassword()
{
return password;
}
public void setPassword(String password)
{
this.password = password;
}
public String getMessage()
{
return message;
}
public void setMessage(String message)
{
this.message = message;
}
public String validateUser()
{
if("hello".equals(username) && "world".equals(password))
{
return "success";
}
this.setMessage("username or password error!");
return "failure";
}
}
启动tomcat服务器 http://localhost:8080/test/login.faces 不是login.jsp (login.faces显示页面标签)
