java - 如何过滤 JPA 存储库？

Question

我正在尝试过滤 JPA 存储库

@RequestMapping("/search")
    public String search(@ModelAttribute Person search, Model model) {
        PersonSpecifications spec = new PersonSpecifications();
        model.addAttribute("people", this.hotelRepository.findAll(spec.lastNameIsLike("Foo")));
        return "people/list";
    }

出现如下错误

The method findAll(Iterable<Long>) in the type CrudRepository<Person,Long> is not applicable for the arguments (Specification<Person>)

请指教。谢谢!

为了使用Specification，您需要让您的存储库扩展JpaSpecificationExecutor。
