ClassByteArrayOutputStreamObjectOutputStreamwriteObject() 实现步骤 下面是具体的代码实现: importjava.io.ByteArrayOutputStream;importjava.io.IOException;importjava.io.ObjectOutputStream;importjava.io.Serializable;publicclassJavaClassToByteArray{publicstaticbyte[]convertToByteArray(Serializableobject)throwsIOException...
打开Java Class文件读取文件内容转换为字节数组关闭文件流 代码示例 importjava.io.File;importjava.io.FileInputStream;importjava.io.IOException;publicclassFileToByteArray{publicstaticbyte[]convertFileToByteArray(StringfilePath)throwsIOException{Filefile=newFile(filePath);byte[]bytesArray=newbyte[(int)file.le...
Object val=null;if(field.getType().equals(int.class) || field.getType().equals(Integer.class)){//整型,按位读取intvalInt = 0;//起始缓存位置(第几个字节,从0开始)intstartBufferIndex = offset / 8;//起始字节已经占用了多少bitintstartByteUsedBit = offset % 8;//起始字节需要读取多少bit(默认...
public class PayloadEncoder { public staticbyte[] getPayload(T command) { ListfieldWrapperList = command.getFieldWrapperList(); ByteBuf buffer = Unpooled.buffer(); fieldWrapperList.forEach(fieldWrapper -> write2ByteBuf(fieldWrapper, command, buffer)); return buffer.array(); } /** * 数据写...
1 、使用bytebuf填充 public class UgvData implements Serializible{ private static final long serialVersionUID = -219988432063763456L; //状态码 byte status; public byte[] toByteArray() { ByteBuf buf = Unpooled.buffer(32); buf.writeByte(this.getStatus()); ...
1.使用ByteArrayStream 和 ObjectStream publicabstractclassByteConvert{publicbyte[]getByte(){try(ByteArrayOutputStreamout=newByteArrayOutputStream();ObjectOutputStreamobjectOutputStream=newObjectOutputStream(out)){objectOutputStream.writeObject(this);objectOutputStream.flush();returnout.toByteArray();}catch(...
classTest {publicstaticvoidmain(String args[]) throws IOException, ClassNotFoundException { TestObject to=newTestObject(); to.setAge(12); to.setName("lisi"); ByteArrayOutputStream byt=newByteArrayOutputStream(); ObjectOutputStream oos=newObjectOutputStream(byt); ...
调用toByteArray()方法获取字节数组。 下面是一个示例代码: 代码语言:java 复制 import java.awt.image.BufferedImage; import java.io.ByteArrayOutputStream; import java.io.File; import java.io.IOException; import javax.imageio.ImageIO; public class ImageToByteArrayExample { public static void main(...
public class ByteStreamTest { public static void main(String args[])throws IOException { ByteArrayOutputStream bOutput = new ByteArrayOutputStream(12); while( bOutput.size()!= 10 ) { // 获取用户输入值 bOutput.write(System.in.read()); ...
out.writeObject(header);byte[] yourBytes = bos.toByteArray(); System.out.println("Hex Data : "+ getHex(yourBytes)); } Java serialization uses its own format which is very unlikely to match what you're after. I'd create a separatemarshallerclass usingByteBufferto write out the values in...
