java - 赫克托 : java. nio.BufferUnderflowException

Question

我正在获取 String 的 ByteBuffer，例如100如下

ByteBuffer data = IntegerSerializer.get().toByteBuffer(Integer.parseInt(data));

并将此数据插入列说“MYCOLUMN”

在读取“MYCOLUMN”列值时，我正在使用:

public Objct myfunction(ByteBuffer data){
        return IntegerSerializer.get().fromByteBuffer(data);
}

但是如果我提到“MYCOLUMN”列，我会收到以下错误

java.nio.BufferUnderflowException
    at java.nio.Buffer.nextGetIndex(Buffer.java:480)
    at java.nio.HeapByteBuffer.getInt(HeapByteBuffer.java:336)
    at me.prettyprint.cassandra.serializers.IntegerSerializer.fromByteBuffer(IntegerSerializer.java:35)

Answer 1

它与this issue 非常相似:

You want to specify Int32Type not IntegerType. The latter is a misnomer and actually represents a BigInteger.
