spring - com.fasterxml.jackson.databind.exc.InvalidDefinitionException：没有为类 org.hibernate.proxy.pojo.bytebuddy.ByteBuddyInterceptor 找到序列化程序

问题描述

我已经经历过：无法编写 JSON：无限递归（StackOverflowError）；嵌套异常 spring boot和许多这样的链接。我正在使用Spring Boot 2.1.6.RELEASE and Data JPA and Postgres示例

这是我的源代码：https ://github.com/JavaHelper/issue-jackson-boot

错误：

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class org.hibernate.proxy.pojo.bytebuddy.ByteBuddyInterceptor and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: org.springframework.data.domain.PageImpl["content"]->java.util.Collections$UnmodifiableRandomAccessList[0]->com.example.demo.entity.StockDailyRecord["stock"]->com.example.demo.entity.Stock$HibernateProxy$f8byIJ39["hibernateLazyInitializer"])

解决方案

您可能会忽略属性hibernateLazyInitializer和handler，这个问题是当您有在序列化之前延迟加载的实体时，实体会完全加载。放在导致这个问题的班级的头上。

@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
