Spring源码：Spring 容器资源加载模板模式应用

模板位于：abstract class AbstractXmlApplicationContext ：

	protected void loadBeanDefinitions(XmlBeanDefinitionReader reader) throws BeansException, IOException {
		Resource[] configResources = getConfigResources(); //加载路径由子类去覆盖实现
		if (configResources != null) {
			reader.loadBeanDefinitions(configResources);
		}
		String[] configLocations = getConfigLocations();
		if (configLocations != null) {
			reader.loadBeanDefinitions(configLocations);
		}
	}

子类的实现：FileSystemXmlApplicationContext extends AbstractXmlApplicationContext

	@Override
	protected Resource getResourceByPath(String path) {
		if (path != null && path.startsWith("/")) {
			path = path.substring(1);
		}
		return new FileSystemResource(path);
	}
