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
