Question

我将 spring-data-jpa升级到1.11.13.RELEASE ，因为该提交：https://github.com/spring-projects/spring-data-commons/commit/5f87c6766863072d761cb02f278b13c8631e655f，

此方法：

List<AppVersion> findByDeviceAndPlatformAndIVersionGreaterThanOrderByIVersionDesc(Device device,App app,Integer versioncode);

订购者找不到该属性，这是该属性：

private Integer iVersion;

引发此异常：

Answer 1

当属性的第二个字符为大写时，解析OrderBy子句时，这是一个错误。

您应该向Spring Data JPA提交错误报告：

https://jira.spring.io/projects/DATAJPA/issues/DATAJPA-1397?filter=allopenissues

与此同时，您必须更改属性名称或在@Query批注中编写查询。

将spring-data-jpa升级到1.11.13.RELEASE命令抛出异常
