一直想研究Java JSF,上網找了下,遺憾的是國內JSF的資料少的可憐.于是上網找了參考點資料,去官方網站下載了JSF的開發包.廢話少說,看配置.
一,配置JSF
把JSF2.0內的兩個開發包jsf-api.jar,jsf-impl.jar拷貝到Eclipse項目的lib目錄中(建立web項目略). 在web.xml中添加以下內容:
<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Development</param-value>
</context-param>
<context-param>
<param-name>com.sun.faces.resourceUpdateCheckPeriod</param-name>
<param-value>-1</param-value>
</context-param>
<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>*.do</url-pattern> <!--此處名字可以隨便起,可以是*.action,*.faces 等 我習慣用*.do-->
</servlet-mapping>
這樣jsf框架已經添加進項目中了.接下來就要建立Bean了.如下所示:
package com.joy.jsf.beans;
//@ManagedBean(name="users") jsf2.0可以不用配置文件來管理bean
public class User {
private String userName;
private String userPassword;
private String errorMessage;
public String getErrorMessage() {
return errorMessage;
}
public void setErrorMessage(String errorMessage) {
this.errorMessage = errorMessage;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserPassword() {
return userPassword;
}
public void setUserPassword(String userPassword) {
this.userPassword = userPassword;
}
public String Check() {
if (!this.userName.equals("JOY") || !this.userPassword.equals("123456")) {
this.errorMessage = "名稱或密碼錯誤";
return "failure";
} else {
return "success";
}
}
}
之后要定制導航規則,新建face-config.xml 如下所示:
<faces-config>
<!-- <application>
<variable-resolver>
org.springframework.web.jsf.DelegatingVariableResolver
</variable-resolver>
</application> -->
<navigation-rule>
<from-view-id>/index.jsp</from-view-id>
<navigation-case>
<from-outcome>success</from-outcome>
<to-view-id>/pages/welcome.jsp</to-view-id>
</navigation-case>
<navigation-case>
<from-outcome>failure</from-outcome>
<to-view-id>/index.jsp</to-view-id>
</navigation-case>
</navigation-rule>
<!--<managed-bean> <managed-bean-name>users</managed-bean-name> <managed-bean-class>
com.joy.jsf.beans.User </managed-bean-class> <managed-bean-scope>request</managed-bean-scope>
</managed-bean> -->
</faces-config>
配置文件建立完了,添加view頁面. index.jsp和welcome.jsp
index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="f" uri=">
<%@ taglib prefix="h" uri=">
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>首頁</title>
</head>
<body>
<f:view>
<h:form>
姓名:<h:inputText value="#{users.userName }" /><br/>
密碼:<h:inputText value="#{users.userPassword }"></h:inputText><br/>
<h:commandButton value="submit" action="#{users.Check}"></h:commandButton>
<br/>
<h:outputText value="#{users.errorMessage}"/><p>
</h:form>
</f:view>
</body>
</html>
welcome.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="f" uri=">
<%@ taglib prefix="h" uri=">
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>歡迎回來</title>
</head>
<body>
<f:view>
<h:form>
Hello <h:outputText value="#{users.userName }"></h:outputText> ,Welcome to here!
</h:form>
</f:view>
</body>
</html>
保存,部署,運行http://localhost:8080/JSF/index.do
二,整合Spring
添加spring開發包,spring.jar,stadard.jar,commons-logging.jar,jstl.jar
web.xml 添加如下配置
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<description>添加Srping支持</description>
<display-name>Spring</display-name>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
然后在face-config.xml中添加
<application>
<variable-resolver>
org.springframework.web.jsf.DelegatingVariableResolver
</variable-resolver>
</application>
從spring工廠中獲取bean ,如果和jsf的托管bean一起使用,則托管bean的優先級要高于spring.
添加applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="
xmlns:xsi="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/tx
<bean id="users" class="com.joy.jsf.beans.User">
</bean>
</beans>
重新部署,運行.
OK.
