Java Spring 数据 MongoDB 和 Java 8 次
Java Spring Data MongoDB and Java 8 Time
我正在尝试在我的 Java Spring 项目中使用 Java 8 LocalDate 和 LocalDateTime，但是我在保存和检索 Mongo 中的日期时遇到问题数据库
我正在使用 Spring 数据 Mongo (1.6.1.Release)。我已经按照 this answer 实现了自己的转换器（在它不起作用之后我尝试直接将 LocalDate 转换为 String）。
我猜的问题是 Spring 数据没有使用转换器，因为我的数据库条目如下所示：
{ "_id" : "frank@steiler.eu", "_class" : "de.steilerdev.myVerein.server.model.User", "firstName" : "Frank", "lastName" : "Steiler", "password" : "ef9aa46dd6f98af4878ed72eac69134ac236b5581e1207bd8e9d4f691ed20a48f4ed8d2b80229e4a649f1e7b5302c2c6166fc783b9cbfff6d8a18ad820652b1e", "salt" : "6b912cac277c6656", "memberSince" : { "year" : 2000, "month" : 1, "day" : 1 }, "birthday" : { "year" : 1994, "month" : 6, "day" : 28 } }
这是我的代码（如果我遗漏了什么，可以找到我的完整项目here）：

好的，所以我想我可能有一些东西给你:)
您有 4 个转换器：
- 本地日期 -> 字符串
- 字符串 -> LocalDate
- 本地日期时间 -> 字符串
- 字符串 -> LocalDateTime
现在，查看您的 class 声明：
public class LocalDateToStringConverter implements Converter<LocalDateTime, String>
public class StringToLocalDateConverter implements Converter<String, LocalDate>
public class LocalDateTimeToStringConverter implements Converter<LocalDateTime, String>
public class StringToLocalDateTimeConverter implements Converter<String, LocalDateTime>
第一个有什么问题？您正在将 LocalDateTime 映射到字符串，而您的 class 名称表明您应该将 LocalDate 映射到字符串。
Copy/paste 有时是一种卑鄙和邪恶的东西。让我知道它是否有帮助！
Ps。您正在创建转换器两次：一次在数据库中-config.xml，而第二次通过 @Component 注释创建。
