迁移JPA数据模型至Java17+SpringBoot3.1后遇OOM问题求助

我正在基于现有JPA数据模型搭建新应用，使用SpringBoot 3.1.3 + Java17。该数据模型此前在Java11+SpringBoot2.7.x环境下的多个应用中运行正常。

升级过程中：

• 用OpenRewrite完成了从javax到jakarta的迁移，构建无报错
• 修复了一处Hibernate报错的无效@Table(indexes={@Index(...)})注解（该注解在SpringBoot2.7环境下未被检测）
• 将所有@Type(type = "yes_no")替换为@Convert(converter = YesNoConverter.class)，解决了Hibernate的相关报错

修复后构建正常，但启动时出现内存溢出（OUT OF MEMORY），即使分配数GB最大堆内存也无法解决。

补充：注解替换示例 #

// FIXME: @Type(type = "yes_no")
@Convert(converter = YesNoConverter.class)
private boolean editable = true;

排查建议 #

• 生成内存dump分析：启动时添加JVM参数 -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/指定路径/dump.hprof，用MAT（Memory Analyzer Tool）或VisualVM打开dump文件，定位占用内存最多的对象，从报错栈看大概率是Hibernate生成SQL时的字符串无限膨胀。
• 检查实体关联配置：排查双向关联是否正确设置了mappedBy，有没有出现循环关联导致Hibernate在生成查询时陷入无限递归；检查是否有实体的关联字段未正确标注，导致Hibernate错误地解析出大量冗余关联。
• 验证Hibernate 6映射兼容性：Hibernate 6对比5.x有不少映射逻辑变化，比如注解解析、类型处理，检查是否有自定义类型、遗留的旧注解（比如未替换完全的javax相关注解）、或者复杂的@Formula/@Subselect等注解未适配新版本。
• 逐步缩小实体范围：临时注释掉部分实体类，重新启动应用，找到导致内存溢出的具体实体，再针对性排查该实体的映射配置。
• 检查Oracle方言配置：显式指定Hibernate的Oracle方言版本，比如`spring.jpa.properties.hibernate.dialect=org.hibernate.dial
