Question

我更新了这些代码行以支持spring-data-cassandra-2.0.7.RELEASE：

CassandraOperations cOps = new CassandraTemplate(session);

自：

Insert insertStatement = (Insert)statement;
CqlTemplate.addWriteOptions(insertStatement, queryWriteOptions);
cOps.execute(insertStatement);

要：

Insert insertStatement = (Insert)statement;
insertStatement = QueryOptionsUtil.addWriteOptions(insertStatement, 
queryWriteOptions);
cOps.insert(insertStatement);

以上更改将丢失以下错误：

Caused by: org.springframework.dao.InvalidDataAccessApiUsageException: Unknown type [interface com.datastax.driver.core.policies.RetryPolicy] for property [retryPolicy] in entity [com.datastax.driver.core.querybuilder.Insert]; only primitive types and Collections or Maps of primitive types are allowed

作为输入传递的查询的类型为com.datastax.driver.core.querybuilder.Insert，其中包含：

INSERT INTO person (name,id,age) VALUES ('name01','123',23) USING TIMESTAMP 1528922717378000 AND TTL 60;

传递包含RetryPolicy和一致性级别的查询选项。根据上面提到的文档，更改无效。任何人都可以让我知道这里有什么问题吗？

我使用Spring 2.0.7.RELEASE和Cassandra驱动程序3.5.0

Answer 1

我能够使用以下更改来处理它：

cOps.getCqlOperations().execute(insertStatement);

如果应用了一致性级别，我如何检查它？

Answer 2

对我来说，这可行：

documentSnapshots

将spring数据cassandra升级到最新的2.0.7.RELEASE后，获取RetryPolicy错误的未知类型
