这个问题是主要的报错信息是at com.example.producer.set.resources.MyWebAppConfigurer.addResourceHand
lers(MyWebAppConfigurer.java:19),看了下我的工程,发现这一行为String projectPath = Class.class.getClass().getResource("/").getPath();空指针异常是Class.class.getClass().getResource("/")返回为null,解决办法是替换为

new MyWebAppConfigurer().getClass().getProtectionDomain().getCodeSource().getLocation().getPath();

new MyWebAppConfigurer()为本类
