我在一个具有命名约定的项目上工作，我需要像这样命名一些字段 xSecondField我正在尝试从 Spring Boot 2.1 迁移到 2.2.1，升级后，当我启动 Spring Boot 应用程序时出现以下错误
java.lang.IllegalArgumentException: Failed to create query for method public abstract com.comp.model.FirstType com.comp.repository.FirstTypeRepository.findFirstByXSecondField(java.lang.Integer)! Unable to locate Attribute with the the given name [XSecondField] on this ManagedType [com.comp.model.FirstType]
XSecondField 的字段。而不是 xSecondField我在迁移指南上没有看到任何类似的东西。是 Spring Data 错误还是我错过了什么？
这是完整的堆栈跟踪

编辑:尝试从 Spring Boot 2.1.2 迁移到 2.1.18 时出现同样的问题(自 2.1.9 以来的问题)
编辑(感谢@Ezequiel):这似乎是相关的 Spring Data Jira 问题:https://jira.spring.io/browse/DATACMNS-1570
最佳答案
如下所述更改您的方法名称findFirstByxSecondField(Integer xSecondField);
关于java - Spring Boot 2.2，JPA > 如果第二个字母大写，则无法定位属性，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59181703/
