java - 找不到请求的操作的编解码器 : [date <-> java. util.Date]

Question

在 Cassandra 中，列类型设置为日期，在模型类中，字段类型设置为 java.util.Date，带有 getter 和 setter。在 com.datastax.driver.mapping.Mapper.save 期间，出现以下异常:

Codec not found for requested operation: [date <-> java.util.Date]

Caused by: com.datastax.driver.core.exceptions.CodecNotFoundException: Codec not found for requested operation: [date <-> java.util.Date]
at com.datastax.driver.core.exceptions.CodecNotFoundException.copy(CodecNotFoundException.java:56)
at com.datastax.driver.core.exceptions.CodecNotFoundException.copy(CodecNotFoundException.java:25)
at com.datastax.driver.mapping.DriverThrowables.propagateCause(DriverThrowables.java:41)
at com.datastax.driver.mapping.Mapper.save(Mapper.java:272)

在 Google 搜索中发现以下内容:

DATE      <-> com.datastax.driver.core.LocalDate : use getDate()

Answer 1

您必须将 java.util.Date 转换为 com.datastax.driver.core.LocalDate

例子:

 LocalDate localDate = LocalDate.fromMillisSinceEpoch(date.getTime());
