Spring Boot Mongo Data org.springframework.data.mapping.context.InvalidPersistentPropertyPath

Question

我想获取带有日期的数据。

请勿阅读此内容

“是否可以使用 LocalDateTime 类查询数据？我真的没有什么要添加的，但是 StackOverflow 告诉我我的问题是所有代码，所以我要添加这个。不过，Stackoverflow 告诉我我的问题是主要是代码，所以我只是在重复自己。我的问题是不言自明的，我真的不知道我应该添加什么”

请勿阅读此内容

POJO：

@Getter
@Setter
@Document(collection = "matches")
public class Match {

    @Id
    private long id;
    private String matchName;
    private LocalDateTime date;

    public static final String SEQUENCE_NAME = "matches";

}

存储库：

@Repository
public interface MatchRepository extends MongoRepository<Match,Long> {

    Page<Match> findAllByDate_DayOfMonth(int date_dayOfYear, Pageable pageable);
}

服务：

@Override
public Page<Match> findTodayMatches(int count, int page) {
    int mPage = page != 0 ? page - 1: 0;
    Pageable pageable = PageRequest.of(mPage, count, Sort.by("date").ascending());
    return matchRepository.findAllByDate_DayOfMonth(LocalDateTime.now().getDayOfMonth(),pageable);
}

错误：

Answer 1

您可以使用以下方法按每月的某天查询集合。并且，存储库查询如下：

@Query("{ $expr: { $eq: [ { $dayOfMonth: '$date' }, ?0 ] } }")
List<Match> findAllByDayOfMonth(int dayOfMonth);

代码repo.findAllByDayOfMonth(4)从数据库中返回所有具有date字段值的文档，例如ISODate("2020-12-04T08:50:00Z")和ISODate("2019-04-04T09:45:00Z")。

另一种方法是实现存储库方法（在存储库实现类中）。但是，上面的解决方案更简单明了。

您得到的异常是 org.springframework.data.mapping.context.InvalidPersistentPropertyPath 表示“异常表明源路径无法完全解析为 PersistentPropertyPath。”。 java.time.LocalDateTime 确实有一个 getDayOfMonth() 方法。但是，我不知道您是否可以按照您想要的方式使用 JDK API 类方法。

我尝试过的代码是 Spring Boot v2.4 和 MongoDB v4.2.8。
