啊... 自己解决啦w

// 找到JFinal的Config类的configJfinal(JFinalConfig jfinalConfig)方法
Class<?> configClass = Class.forName("com.jfinal.core.Config");
Method configJFinal = configClass.getDeclaredMethod("configJFinal", JFinalConfig.class);

// 因为它的访问级别是Package Private, 需要setAccessible(true)才能调用
configJFinal.setAccessible(true);

// 用Jboot的配置文件调用
configJFinal.invoke(null, new JbootAppConfig());
