【中文标题】com.fasterxml.jackson.databind.exc.InvalidDefinitionException：没有为类 org.hibernate.proxy.pojo.bytebuddy.ByteBuddyInterceptor 找到序列化程序 [重复]【英文标题】：com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class org.hibernate.proxy.pojo.bytebuddy.ByteBuddyInterceptor [duplicate] 【发布时间】：2019-12-14 06:43:30 【问题描述】：我已经浏览过：Could not write JSON: Infinite recursion (***Error); nested exception 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：

【问题讨论】：
Related? @pirho - 相关解决方案在我的情况下也不起作用。最新版的boot 2.1.6有什么需要做的吗？ @duffymo - 它不是重复的问题，所以请再次阅读问题 ***.com/questions/52656517/… 两个不同的答案将其作为解决方案。我在你的问题中没有看到。 【参考方案1】：您可能会忽略属性 hibernateLazyInitializer 和 handler，这个问题是当您在序列化之前延迟加载实体时，实体会完全加载。放在导致这个问题的班级的头上。
@JsonIgnoreProperties("hibernateLazyInitializer", "handler")
【讨论】：
仅此一项在我的情况下不起作用。大家可以用我帖子里的源码分享测试，git链接【参考方案2】：不确定这是如何工作的，但将两件事混合使用效果很好。从这里参考：Great Link
我同时添加了@JsonIgnoreProperties("hibernateLazyInitializer", "handler") 和@JsonIgnore 反序列化后无法保留双向关系。
这是我的课

@JsonIgnore
private Set<StockDailyRecord> stockDailyRecords = new HashSet<>(0);

public Stock(Integer stockId, String stockCode, String stockName, Set<StockDailyRecord> stockDailyRecords,

super(createdDate, lastUpdateDate, createUser, lastUpdateUser);
this.stockId = stockId;
this.stockCode = stockCode;
this.stockName = stockName;
this.stockDailyRecords = stockDailyRecords;
注意：既然是@ManyToOne关系，所以我们不能不从Stock中排除StockDailyRecord，总是像从Stock获取Stock数据一样
