Springboot出现如下错误
No serializer found for class com.example.videotest2vue.entity.VideoDetail and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: java.util.ArrayList[0])

经检查，上面报错信息中标注的类没有加getter方法，加上即可解决。
