自己顶一下 ,求大神

配置了实体类的扫描路径了吗

映射错误吧 是不是哪个字段写错了

id映射使用uuid尝试下

字面意思是没有这个映射 看一下 映射关系配置是否出错 如果确认没有 可以试着往上找找看 数据库连接是否连上

把配置文件给发出来看看

楼主解决没有出了和你一样的问题

Spring boot + Spring Data JPA + Hibernate缓存问题
如题,项目框架为Spring boot + Spring Data JPA + Hibernate,hibernate中有Query.list()和query.iterator()方法,其中query.iterator()方法去查询时会用到缓存,返回的参数类型是Iterator,如果使用Spring Data JPA+hibernate如何实现查询一个list使用到缓存呢,JPA中的PagingAndSortingRepository接口中的findAll()方法返回的Iterator类型好像和query.iterator()的效果不一样,哪个哥们可以解答下,万分感激!

spring data jpa 拦截
spring boot项目,数据层spring data jpa 现在想在数据层把个人信息的敏感字段加密?因为项目过大,如何事项在查询语句执行之前增加拦截,将查询参数进行加密,及获取数据后将查询数据进行解密。
JPA javax.persistence.TransactionRequiredException: no transaction is in progress
### 背景 现在项目使用jpa做数据持久化,在dao层使用entityManager进行数据操作。 项目使用spring的声明式事务管理,拦截在service层。 ### 问题 entityManager.presist(Entity)可以持久化数据到数据库,在批量保存时调用entityManager.flush()时就会出异常: javax.persistence.TransactionRequiredException: no transaction is in progress

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?

兼职程序员一般可以从什么平台接私活?
这个问题我进行了系统性的总结,以下将进行言简意赅的说明和渠道提供,希望对各位小猿/小媛们有帮助~ 根据我们的经验,程序员兼职主要分为三种:兼职职位众包、项目整包和自由职业者驻场。 所谓的兼职职位众包,指的是需求方这边有自有工程师配合,只需要某个职位的工程师开发某个模块的项目。比如开发一个 app,后端接口有人开发,但是缺少 iOS 前端开发工程师,那么他们就会发布一个职位招聘前端,来配合公司一...
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发
