Datastax cassandra QueryBuilder插入错误（java）-Java 学习之路

环境：

java 7
cassandra 2.1.2在我的本地开发工作站上运行在Windows 8.1上的一个简单节点中
驱动程序cassandra-driver-core-2.1.2
运行环境：apache karaf 2.3.8

我尝试通过在由简单类型（坐标为x和y）定义的列中给出json来插入行 .

我构建了这个java语句：

Statement statement = QueryBuilder
.insertInto("myKeySpace", "myTable")
.value("myKeyColumn", "myKeyValue")
.value("coordinates", "{\"x\":10.4,\"y\":20.3}");

并执行此时：

mySession.execute(statement);

我有以下错误（完整堆栈跟踪在此消息的末尾）：

com.datastax.driver.core.exceptions.InvalidQueryException: Not enough bytes to read 0th field java.nio.HeapByteBuffer[pos=0 lim=1 cap=1]

[在下面的CQL语句中，我已经对列名匿名了，引号可能是错误的，但问题出在上面的java语句中]

我的cassandra表和类型：

CREATE TABLE IF NOT EXISTS "myTable" ( 
    "myKeyColumn" text,
    coordinates FROZEN<coordinates>,
    PRIMARY KEY ("myKeyColumn") 
);

CREATE TYPE IF NOT EXISTS coordinates (
      x double,
      y double
);

在Datastax DevCenter中执行以下查询时，这样可以正常工作：

INSERT INTO "myTable"("myKeyColumn","coordinates")
VALUES ('myKeyValue',{"x":10.4,"y":20.3});

欢迎任何帮助！ :-)

驱动程序v2.1.2中的UDT存在已知问题，将在v2.1.3中解决 . 在此期间，您可以尝试这里给出的解决方法：

https://datastax-oss.atlassian.net/browse/JAVA-500

如：
```
Cluster.builder().withProtocolVersion(ProtocolVersion.V3)
```
看看是否有帮助

我从github下载了cassandra-driver-parent并查看了core的测试 . 我找到了一种不同的方式来调用这些类型：
```
UDTValue udtValue = keyspaceBuilder.getCluster().getMetadata().getKeyspace("myKeyspace").getUserType("coordinates").newValue()
    .setDouble("x", x)
    .setDouble("y", y);
```
然后，在QueryBuilder中，我追加：
```
.value("coordinates", udtValue);
```
这很有效 .
