<P>
Provides a Spring bean scope resolver when using Spring
instantiated pages with the &#64;Component annotation.
<p/>
This scope meta data resolver will resolve "prototype" scope for any Click
Page bean, and "singleton" scope for any other bean.
<h3>Example &#64;Component Page</h3>
An example Page class is provided below which uses the Spring &#64;Component annotation.
<pre class="prettyprint">
package com.mycorp.page;
import javax.annotation.Resource;
import org.apache.click.Page;
import org.springframework.stereotype.Component;
import comp.mycorp.service.CustomerService;
&#64;Component
public class CustomerEditPage extends Page {
&#64;Resource(name="customerService")
private CustomerService customerService;
..
} </pre>
Note in this example page the customerService with the &#64;Resource
annotation is injected by Spring after the page instance has been instantiated.
<h3>Example Spring Configuration</h3>
An example Spring XML configuration is provided below.
<pre class="codeConfig">
&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;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-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"&gt;
&lt;context:component-scan base-package="<span class="red">com.mycorp</span>" scope-resolver=<span class="blue">"org.apache.click.extras.spring.PageScopeResolver"</span>/&gt;
&lt;/beans&gt; </pre>
In this example any page class under the base package "com.mycorp" which
includes the &#64;Component annotation will have "prototype" scope.
