找不到请求的操作的编解码器：[日期<-> java.util.Date]

Question

在Cassandra中，列类型设置为Date，在Model类中，字段类型设置为具有getter和setter的java.util.Date。在此期间，com.datastax.driver.mapping.Mapper.save我收到以下异常：

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.mapping.Mapper.save(Mapper.java:272)

在Google搜索过程中发现以下内容：

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());
