JSF教程 - JSF JSF_Spring示例
下面的代码显示了如何使用Spring来使用JSF。
例子
以下代码来自PrinterImpl.java。
package cn.w3cschool.common;
import javax.inject.Named;
@Named
public class PrinterImpl implements Printer{
public String print() {
return "JSF 2 + Spring Integration";
}
}
下面的代码来自Printer.java。
package cn.w3cschool.common;
public interface Printer{
public String print();
}
以下代码来自default.xhtml。
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html">
<h:body>#{userBean.printMsgFromSpring()}</h:body>
</html>
下面的代码来自UserBean.java。
package cn.w3cschool.common;
import javax.inject.Inject;
import javax.inject.Named;
import org.springframework.context.annotation.Scope;
@Named
@Scope("session")
public class UserBean {
@Inject
Printer printer;
public void setPrinter(Printer p) {
this.printer = p;
}
public String printMsgFromSpring() {
return printer.print();
}
}

Spring配置
以下代码来自applicationContext.xml。
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"> <context:component-scan base-package="com.w3cschool" /> </beans>
运行
将生成的WAR文件从目标文件夹复制到Tomcat部署文件夹，并运行Tomcat-Install-folder/bin/startup.bat。
Tomcat完成启动后，在浏览器地址栏中键入以下URL。
http://localhost:8080/simple-webapp/default.xhtml
