java-我正在使用spring-data-couchbase,但是从方法名称创建查询不起作用

我正在使用spring-data-couchbase,但是从方法名称创建查询无效.以下是我的代码：

弹簧couchbase.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns:beans="http://www.springframework.org/schema/beans"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <couchbase:couchbase bucket="comment" host="192.168.20.118,192.168.20.71" />
    <couchbase:template/>

    <jpa:repositories base-package="com.david.comment.core.repository" />

</beans:beans>

库：

public interface CommentRepository extends PagingAndSortingRepository<CommentDoc, String> {
    public Page<CommentDoc> findByUserId(String userId, Pageable pageable);
}

域：

@Document
@Data
public class CommentDoc {

    @Id
    private String id;

    /**
     * 话题
     */
    @Field
    private String topicId;

    /**
     * 用户ID
     */
    @Field
    private String userId;
}

测试：

    @Test
    public void testFindByC1() {
        Pageable pageable = new PageRequest(0, 10);
        Page<CommentDoc> comments = commentRepository.findByUserId("user01", pageable);
        for(CommentDoc commentDoc : comments) {
            logger.debug("doc: {}", commentDoc);
        }
    }

例外：

请有人帮我！我该如何解决.

解决方法:

我对此并不陌生,但刚刚经历了它. Couchbase的东西似乎并不支持其他Spring Data存储库中提供的所有功能.

>您必须添加一个名为commentdoc / byUserId的生产视图(在开发视图中,设计文档名称= commentdoc,视图名称= byUserId).不要忘记发布.像(fix classname)这样的东西：

function (doc, Meta) {
    if(doc._class == "com.david.XXX.CommentDoc" && doc.userId){
        emit(doc.userID, null);
     }
 }

>将您的回购签名从String userId更改为Query userId
>传递查询对象.就像是：

Query query = new Query();
query.setKey(ComplexKey.of("useridofinteres="));
commentRepository.findByUserId(query, pageable);
