Question

我有以下JPA存储库：

public interface ProductRepositoryJPA extends CrudRepository<Product,String>,
                           PagingAndSortingRepository<Product,String> {

    @Override
    @EntityGraph(value="EVERYTHING", type= EntityGraph.EntityGraphType.FETCH)
    Product findOne(String id);


}

如果我尝试使用spring-boot 2.0.0.M4编译，我会遇到以下错误：

ProductRepositoryJPA.java:[21,5] method does not override or implement a method from a supertype

如果我使用Spring Boot 1.5.6.RELEASE，代码编译得很好。

如果删除@Override注释并将Spring Boot保留在版本2.0.0.M3，它也可以正常编译。

这是Spring Boot 2.0.0.M3的依赖树：

谢谢！

在注释掉我的“覆盖”方法之后，允许使用Spring-Boot-2.0.0.M4编译构建 - 我意识到spring-data-commons 2.0.0中不再支持findOne（T id）。看起来它已被findById（T id）方法取代。

将Spring Boot 1.5.6.RELEASE升级到2.0.0.M4时出现Spring Data JPA编译错误
