Spring data cassandra-无法为WriteOptions的属性[retryPolicy]解析数据类型

Question

Spring引导版本2.1.9.RELEASE并为spring-boot-starter-data-cassandra]使用依赖项]

对于以下代码段

WriteOptions ttlOption = WriteOptions.builder().ttl(5).build();
CassandraBatchOperations batchOperations = cassandraTemplate.batchOps();
batchOperations.insert(myEntityClass, ttlOption);
我们目前收到以下异常

Caused by: org.springframework.data.mapping.MappingException: Cannot resolve DataType for property [retryPolicy] in entity [org.springframework.data.cassandra.core.cql.WriteOptions]; Consider adding @CassandraType.

我想念什么？

Spring boot版本2.1.9.RELEASE并使用spring-boot-starter-data-cassandra的依赖关系对于以下代码段，WriteOptions ttlOption = WriteOptions.builder（）。ttl（5）.build（）; ...
