承接前文Spring源码情操陶冶-AbstractApplicationContext#initApplicationEventMulticaster

约定web.xml配置的contextClass为默认值XmlWebApplicationContext

直接源码AbstractRefreshableWebApplicationContext#onRefresh

	/**

	 * Initialize the theme capability.

	 */

	 protected void onRefresh() {

		 //设置themeSource，设置情况与前文一致，查找的bean为themeSource

		this.themeSource = UiApplicationContextUtils.initThemeSource(this);

	}

初始化themeSource主题源，默认使用ResourceBundleThemeSource
