bean没有字段时，序列化报错


com.fasterxml.jackson.databind.exc.InvalidDefinitionException: 
No serializer found for class dyyx.test.MyIntfImpl and no properties discovered to create BeanSerializer 
(to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS)

spring.jackson.serialization.FAIL_ON_EMPTY_BEANS=false

配置文件里配置 

spring.jackson.serialization.FAIL_ON_EMPTY_BEANS=false
