在存储库中的切片 `返回类型与PagingAndSortingRepository不兼容`

Slice in repository `The return type is incompatible with PagingAndSortingRepository`

问题

我已经创建了返回类型为Slice的findAll函数,然后遇到了这个错误:
返回类型与PagingAndSortingRepository<Book, Long>.findAll(Pageable)不兼容

这是我的存储库代码:

import org.springframework.data.domain.Slice;

@SuppressWarnings("unused")
@Repository
public interface BookRepository extends JpaRepository<Book, Long>, JpaSpecificationExecutor<Book> {
    Slice<Book> findAll(Pageable pageable);
}

我在这里做错了什么?

英文:

I have create findAll function with return type Slice then got this error:
The return type is incompatible with PagingAndSortingRepository&lt;Book,Long&gt;.findAll(Pageable)
Here is my code in repository:

import org.springframework.data.domain.Slice;

@SuppressWarnings(&quot;unused&quot;)
@Repository
public interface BookRepository extends JpaRepository&lt;Book, Long&gt;, JpaSpecificationExecutor&lt;Book&gt; {
    Slice&lt;Book&gt; findAll(Pageable pageable);
}

What did I do wrong here?

&gt; 这个方法已经在JpaRepository中可用,它返回一个Page,你不能重新定义它的返回类型,而且你实际上也不需要它,因为它已经存在。

>That method is already available in the JpaRepository and returns a Page you >cannot redifine it with another return type and you don't actually need it >because it is already there.
