实战spring+jsf

JSF本身提供了强大的Bean管理功能。但Spring作为一种轻量的容器，在管理Bean方面有着不可替代的优势，使用起来很方便。在Spring流行的今天，怎么能少了在JSF中整合Spring呢？下面的示例比较简单，但也能清楚的表达如何将JSF+Spring两者互相整合起来。

首先新建web项目myJSF,然后需要找到下图的jar包导入到WEN-INF/lib下：

可以到http://download.youkuaiyun.com/my去下载一个JSF+SPRING的zip包，解压后就可以用了！

第一步：创建faces-config.xml

代码:

<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="1.2"
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">
  <application>
   <action-listener>
    org.springframework.web.jsf.DelegatingVariableResolver
   </action-listener>
   
  </application>
  <navigation-rule>
  <description>Navigation from the hello page</description>
  <from-view-id>/ScockInput.jsp</from-view-id>
  <navigation-case>
  	<from-outcome>stockOutputSuccess</from-outcome>
  	<to-view-id>/StockOut.jsp</to-view-id>
  </navigation-case>
  <navigation-case>
  	<from-outcome>stockOutputFailure</from-outcome>
  	<to-view-id>/StockError.jsp</to-view-id>
  </navigation-case>
  </navigation-rule>
</faces-config>

第二步：创建applicationContext.xml

代码：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
	<bean id="stockBean" class="com.sterning.springjsf.StockValueFetcher"></bean>
</beans>

第三步：创建web.xml

代码:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 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-app_2_5.xsd">
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/applicationContext.xml</param-value>
	</context-param>
	<servlet>
		<servlet-name>FacesServlet</servlet-name>
		<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>FacesServlet</servlet-name>
		<url-pattern>/faces/*</url-pattern>
	</servlet-mapping>
	<session-config>
		<session-timeout>30</session-timeout>
	</session-config>
	<welcome-file-list>
		<welcome-file>faces/ScockInput.jsp</welcome-file>
	</welcome-file-list>
</web-app>

第四步：创建ScockInput.jsp页面

代码:

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<f:view>
	<html>
		<head>
			<title>Insert title here</title>
		</head>
		<body>
			<h:form id="stockForm">
		<h1>请输入一个字符串,如：ABC\DEF</h1>
		<p>
			<h:inputText id="stockSymbolinput" value="#{stockBean.symbolName }"
			required="true"></h:inputText>
		</p>
		<h:commandButton id="stockSubmit" type="submit" value="提交"
			action="#{stockBean.findStockValue }"></h:commandButton>
		</h:form>
		</body>
	</html>
</f:view>

第五步：创建StockOut.jsp

代码:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
 <%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
 <%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>

	<html>
		<head>
			<title>Insert title here</title>
		</head>
		<body>
		 <f:view>
			<h1>
				输入的字符串是:
				<h:outputText value="#{stockBean.symbolName }"></h:outputText>
				对应的值:
				<h:outputText value="#{stockBean.symbolValue }"></h:outputText>	
			</h1>
	     </f:view>
		</body>
	</html>

第六步：创建Stockerror.jsp

代码:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>错误页面</title>
</head>
<body>
	<f:view>	
	所查找的字符串
		<h1>
			<h:outputText value="#{stockBean.symbolName }"></h:outputText>
		</h1>
		不存在请再次查找！
	</f:view>
</body>
</html>

第七步：创建StockValueFetcher

代码:

package com.sterning.springjsf;

import java.util.HashMap;
import java.util.Map;

public class StockValueFetcher {
	private Map<String, String> stockSymbolsAndValues;
	private String symbolName;
	private String symbolValue;

	public StockValueFetcher() {
		stockSymbolsAndValues = new HashMap<String, String>();
		stockSymbolsAndValues.put("ABC", "10");
		stockSymbolsAndValues.put("DEF", "20");
		stockSymbolsAndValues.put("GHJ", "10");
	}

	public Map<String, String> getStockSymbolsAndValues() {
		return stockSymbolsAndValues;
	}

	public void setStockSymbolsAndValues(
			Map<String, String> stockSymbolsAndValues) {
		this.stockSymbolsAndValues = stockSymbolsAndValues;
	}

	public String getSymbolName() {
		return symbolName;
	}

	public void setSymbolName(String symbolName) {
		this.symbolName = symbolName;
	}

	public String getSymbolValue() {
		return symbolValue;
	}

	public void setSymbolValue(String symbolValue) {
		this.symbolValue = symbolValue;
	}
  public String findStockValue(){
	  boolean symbolFound = stockSymbolsAndValues.containsKey(symbolName);
	  if(symbolFound){
		  symbolValue = stockSymbolsAndValues.get(symbolName);
		  return "stockSymbolSuccess";
	  }else{
		  return "stockSymbolFailure";
	  }
  }
}

写好了、自己调试下、希望大虾们多多指点！
