Hibernate Search中LocalDate的DateBridge

Question

我在SpringBoot應用程序中使用Hibernate search 11.5.2.Final。

我正在嘗試搜索實體Book createdAt字段。

當我運行它時，應用程序退出，並顯示異常

Unable to create bean for LocalDateBridge

對於類型為Long字段，我也得到了相同的異常

我的實體看起來像這樣

@Indexed
@Entity
public class Book {
    @Id 
    private Long id;


    @Field
    @DateBridge(resolution=Resolution.DAY)
    private LocalDate createdAt;

    // Other fields and setters & getters
}

這是完整堆棧跟蹤

Answer 1

嘗試刪除@DateBridge(resolution=Resolution.DAY) ：對於您的情況，它無用，因為本地日期的分辨率已經是當天。

該問題可能是由於java.time類型不支持顯式解析，而僅對遺留java.util.Date / java.util.Calendar類型（實際上可能有用）支持。

如果這不能解決問題，請在您的問題中粘貼完整的堆棧跟蹤。

Answer 2

根據您的堆棧跟蹤，您正在將String對象傳遞給查詢構建器，而應該使用LocalDate對象，因為您的字段的類型為LocalDate 。 將用戶提供的字符串解析為LocalDate ，然后將該對象傳遞給查詢構建器。
