问题描述
当我尝试通过findAll(Pageable)读取整个存储桶时，效果很好。
当我尝试过滤分页读取时-findByUserId（由userId查找）-获取java.lang.indexoutofboundsexception。
过滤记录的here
实体：
@JsonIgnoreProperties(ignoreUnkNown = true)
public class Event {
@Id
@GeneratedValue
public String id;
@Field
public String userId;
@Field
public String description;
}
存储库：
@Repository
public interface EventRepository extends CouchbaseRepository<Event,String> {
Page<Event> findByUserId(String userId,Pageable page);
}
索引：
在#primary上创建主索引event
在userId（event）上的{userId =“ com.example.demo.Event”）上创建索引_class
图书馆：
春季靴：2.3.4
spring-data-couchbase：4.0.4
获取以下堆栈跟踪：

解决方法
简短的长答案：
spring-data-couchbase v4.0.4仍在开发中。一些功能被破坏了。 github ongoing work
Spring Boot 2.3使用spring-boot-couchbase v4.0并存在问题。 JHipster Google group discussion
解决方案：
降级到旧版本的Spring Boot。我将spring-boot的版本从2.3.4降级到2.2.2
