Could not create query for public abstract org.springframework.data.domain.Page com.example.repository.DocumentsRepository.findBytypeid
大家好，我有以下 2 个相关的表格：
CREATE TABLE `documents` (
`id` int(11) NOT NULL,
`date_created` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
`name` varchar(255) NOT NULL,
`type_id` int(11) NOT NULL,
`file` varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
CREATE TABLE `documenttypes` (

请帮忙。我什至不知道我到底在哪里。
抛出的异常已经解释了发生了什么：
Caused by: java.lang.IllegalArgumentException: Paging query needs to have a Pageable parameter! Offending method public abstract org.springframework.data.domain.Page com.example.repository.DocumentsRepository.findBytypeid(java.lang.Integer,org.springframework.boot.autoconfigure.data.web.SpringDataWebProperties$Pageable)
而 Pageable 应该来自 spring-data 包，其完全限定名称是 org.springframework.data.domain.Pageable
所以你只是为 Pageable
导入了错误的包

请帮忙。我什至不知道我到底在哪里。
抛出的异常已经解释了发生了什么：
Caused by: java.lang.IllegalArgumentException: Paging query needs to have a Pageable parameter! Offending method public abstract org.springframework.data.domain.Page com.example.repository.DocumentsRepository.findBytypeid(java.lang.Integer,org.springframework.boot.autoconfigure.data.web.SpringDataWebProperties$Pageable)
而 Pageable 应该来自 spring-data 包，其完全限定名称是 org.springframework.data.domain.Pageable
所以你只是为 Pageable
