Netty io.netty.buffer.ByteBuf.array() throws exception - direct buffer

I wanted to print io.netty.buffer.ByteBuf as string. But io.netty.buffer.ByteBuf.array() throws exception as follows.

java.lang.UnsupportedOperationException: direct buffer at io.netty.buffer.PooledUnsafeDirectByteBuf.array(PooledUnsafeDirectByteBuf.java:343)

Could some one help me to get the byte[] from byte io.netty.buffer.ByteBuf.

Thanks.

Solution

  • OK, I have figured out a way to print the values. If anyone is interested,

    byte[] bytes = new byte[buf.readableBytes()];
buf.duplicate().readBytes(bytes);
System.out.println(new String(bytes));
