现有一个表要根据表tablet中一个字段group值假设为1，根据group=1查出这一行数据的id字段值为多少，并将查处的所有id值写入一个集合中，在springboot上用jpa应该怎么写，详细表述过程

您好，根据您的描述，可以使用JPA的@Query注解来实现该功能。具体实现步骤如下：

1. 在对应的Repository接口中定义一个方法，使用@Query注解指定SQL语句，例如：

@Query("select id from tablet where group = 1")
List<Integer> findIdsByGroup();

2. 在Service层调用该方法，将查询结果存入一个集合中，例如：

List<Integer> idList = tabletRepository.findIdsByGroup();

3. 对于Spring Boot应用，需要在pom.xml文件中添加相关依赖，例如：

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

以上就是使用JPA在Spring Boot上实现根据group值查询id集合的方法，希望能对您有所帮助。
