java - PagingAndSortingRepository 方法在与 spring data jdbc 一起使用时抛出错误

Question

所有与 CrudRepository 相关的 CRUD 方法都按预期工作，但是当尝试使用 findAll 进行分页或排序时会抛出错误。我正在使用 Lovelace-SR2 发布序列。该类只有一个字段，即@Id。根据文档支持分页和排序。 https://docs.spring.io/spring-data/jdbc/docs/1.0.2.RELEASE/reference/html/#repositories

// this throws error
Iterable<FirstAggregate> aggregates = repo.findAll(Sort.unsorted());

public class FirstAggregate {
    @Id
    private UUID id;

    public FirstAggregate(UUID id) {
        this.id = id;
    }

    public FirstAggregate() {
    }

    public UUID getId() {
        return id;
    }

    public void setId(UUID id) {
        this.id = id;
    }
}

Answer 1

更新:对 PagingAndSortingRepository 的支持已登陆 Spring Data JDBC，并将从 2.0.0 M3` 开始提供。

你正在引入 spring-boot-starter-data-jdbc 但你标记了你的问题 spring-data-jpa。

因此，如果您要使用 JPA 依赖项，则必须引入 JPA 依赖项。

如果您想使用 Spring Data JDBC，坏消息是:We don't support paging and sorting yet .

文档没有说明这是受支持的，尽管看起来确实如此。分页和排序仅在描述Spring Data通用概念的通用部分中引用。
