- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?

我错过了什么吗?我现在有点陷入这个问题。对我有用的另一种解决方案是从 MatchRepo 界面中删除这两行代码:
//If I delete the line below, everything works fine.
Match findMatchByCodeName(String codeName);
//If I delete the line below, everything works fine.
Iterable<Match> findMatchesByCodeName(@Param("codeName") String codeName);
我只是使用从扩展 Neo4jRepository 接口(interface)扩展的 findAll() 方法,然后使用 java-8 流来过滤与 codeName 匹配的 Match 对象。确实是一个丑陋的解决方案。如果有人知道如何以正确的方式解决此问题,请提供帮助。
最佳答案
编辑:您似乎使用了不兼容版本的 Spring-Data-Commons 和 Spring Data Neo4j。您将 SDN 版本覆盖为 5.0.9,但不是发布版本。
无论如何,对于派生方法名称,推荐的命名方案是这样的:
package io.sciro.leaderdata.repo;
import io.sciro.leaderdata.domain.Match;
import org.springframework.data.neo4j.repository.Neo4jRepository;
import org.springframework.data.repository.query.Param;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;
import org.springframework.stereotype.Repository;
@Repository
@RepositoryRestResource(path = "match", collectionResourceRel = "match")
public interface MatchRepo extends Neo4jRepository<Match, Long> {
Match findOneByCodeName(String codeName);
Iterable<Match> findAllByCodeName(@Param("codeName") String codeName);
}
