org.apache.ibatis.executor.loader.javassist.JavassistProxyFactory$EnhancedResultObjectProxyImpl and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.

當我用Springboot和mybatis進行延遲加載時候報出如下的錯誤:

org.apache.ibatis.executor.loader.javassist.JavassistProxyFactory$EnhancedResultObjectProxyImpl and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS)

這里我的解決方法是在yml的配置中設置:

spring:
  jackson:
    serialization:
     FAIL_ON_EMPTY_BEANS: false

同理在properties中設置為:

spring.jackson.serialization.FAIL_ON_EMPTY_BEANS=false

這里搜索到的很多說將bean中屬性為private，改為public ,我沒有試過也不建議這么做.
