无法反序列化]，根本原因是 java.io.EOFException: null

Question

我看到了有关此主题的一些问题，但我的案例没有得到任何有效的解决方案

我的杰森序列化有一个例外，我有以下类

当我执行 GET Pacientes 时，我遇到了序列化权限类型的异常

我正在使用框架 Spring boot 和 spring data jpa

Answer 1

看起来您正在尝试反序列化空流。

Answer 2

您不能简单地通过 REST 接口传输数据库实体，您必须创建 DTO 并传输它们而不是您的实体。

Answer 3

对我来说，原因是在关联上使用

@Column

而不是

@JoinColumn

。能够通过打开正在运行的查询的日志记录来找出答案：

spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
logging.level.org.springframework.transaction=DEBUG
logging.level.org.hibernate=DEBUG
logging.level.org.hibernate.SQL=debug
logging.level.org.hibernate.type.descriptor.sql=trace

tbh，不确定实际上需要哪些属性，但我在其他一些问题上找到了它们，并在调试时将它们全部打开。在日志中，我看到所获取的每一列都有一行，并且在我收到异常之前记录的最后一个是我有错误注释的关联的列值。

Answer 4

对我来说，相关错误“无效的流头：C3020D1B”是由于数字数据类型引起的，通过更改为长数据类型XD解决了，投入了几个小时!!!

Answer 5

对我来说，这个问题是由于声明类型为

Number

的字段引起的（将其更改为

Double

修复了错误）。
