在eclipse中开发cassandra程序的步骤

1.建立java project
2.Import cassandra中的interface目录下的gen-java
3.加入lib目录下的jar文件
4.哦了
5.示例代码：
import java.io.UnsupportedEncodingException;
import java.util.Date;
import java.util.List;
import org.apache.cassandra.thrift.Cassandra;
import org.apache.cassandra.thrift.Column;
import org.apache.cassandra.thrift.ColumnOrSuperColumn;
import org.apache.cassandra.thrift.ColumnParent;
import org.apache.cassandra.thrift.ColumnPath;
import org.apache.cassandra.thrift.ConsistencyLevel;
import org.apache.cassandra.thrift.InvalidRequestException;
import org.apache.cassandra.thrift.NotFoundException;
import org.apache.cassandra.thrift.SlicePredicate;
import org.apache.cassandra.thrift.SliceRange;
import org.apache.cassandra.thrift.TimedOutException;
import org.apache.cassandra.thrift.UnavailableException;
import org.apache.thrift.TException;
import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TProtocol;
import org.apache.thrift.transport.TSocket;
import org.apache.thrift.transport.TTransport;
public class test {
public static final String UTF8 = "UTF8";
public static void main(String[] args) throws UnsupportedEncodingException,
InvalidRequestException, UnavailableException, TimedOutException,
TException, NotFoundException {
TTransport tr = new TSocket("10.28.0.186", 9160); TProtocol proto = new TBinaryProtocol(tr);
Cassandra.Client client = new Cassandra.Client(proto);
tr.open();
//System.out.println("dddddd");
String keyspace = "Keyspace1";
String columnFamily = "Standard1";
String keyUserID = "1";
// insert data
long timestamp = System.currentTimeMillis();
ColumnPath colPathName = new ColumnPath(columnFamily);
colPathName.setColumn("fullName".getBytes(UTF8));
client.insert(keyspace, keyUserID, colPathName, "Chris Goffinet"
.getBytes(UTF8), timestamp, ConsistencyLevel.ONE);
ColumnPath colPathAge = new ColumnPath(columnFamily);
colPathAge.setColumn("age".getBytes(UTF8));
client.insert(keyspace, keyUserID, colPathAge, "24".getBytes(UTF8),
timestamp,
ConsistencyLevel.ONE);
// read single column
System.out.println("single column:");
Column col = client.get(keyspace, keyUserID, colPathName,
ConsistencyLevel.ONE).getColumn();
System.out.println("column name: "+ new String(, UTF8));
System.out.println("column value: "+ new String(col.value, UTF8));
System.out.println("column timestamp: "+ new Date(col.timestamp));
// read entire row
SlicePredicate predicate = new SlicePredicate(); SliceRange sliceRange = new SliceRange();
sliceRange.setStart(new byte[0]);
sliceRange.setFinish(new byte[0]);
predicate.setSlice_range(sliceRange);
System.out.println("\nrow:");
ColumnParent parent = new ColumnParent(columnFamily); List<ColumnOrSuperColumn> results = client.get_slice(keyspace,
keyUserID, parent, predicate, ConsistencyLevel.ONE);
for (ColumnOrSuperColumn result : results) {
Column column = result.column;
System.out.println(new
String(, UTF8) + " -> "
+ new String(column.value, UTF8));
}
tr.close();
}
}。
