步骤一:将对象转换为字节数组 要将Java对象转换为字节数组,我们可以使用Java中的ByteArrayOutputStream类。这个类提供了将数据写入字节数组的功能。下面是相应的代码示例: ByteArrayOutputStreambos=newByteArrayOutputStream();try(ObjectOutputout=newObjectOutputStream(bos)){out.writeObject(object);// object是要转换...
* 对象转字节数组 */ public static byte[] objectToBytes(Object obj) throws IOException { try( ByteArrayOutputStream out = new ByteArrayOutputStream(); ObjectOutputStream sOut = new ObjectOutputStream(out); ){ sOut.writeObject(obj); sOut.flush(); byte[] bytes = out.toByteArray(); return ...
byte[] bytes = out.toByteArray(); returnbytes; } } /** * 字节数组转对象 */ publicstaticObject bytesToObject(byte[] bytes)throwsIOException, ClassNotFoundException { try( ByteArrayInputStream in =newByteArrayInputStream(bytes); ObjectInputStream sIn =newObjectInputStream(in); ...
要将Java对象转换为byte数组,你可以使用Java的序列化和反序列化机制。以下是一个示例代码,其中将一个名为obj的Java对象转换为byte数组: import java.io.ByteArrayOutputStream; import java.io.ObjectOutputStream; import java.io.IOException; public class ObjectToByteArray { public static byte[] convertToByte...
private static void fillData(FieldWrapper fieldWrapper, Object instance, ByteBuf buffer) { Field field = fieldWrapper.getField(); field.setAccessible(true); String typeName = field.getType().getName(); try { switch (typeName) { case "java.lang.Boolean": ...
Object转byte与byte转Object 今天实现一下如何从Object去转为byte和如何从byte转为Object。 首先,定义一个类student: package com.byteToObject;importjava.io.Serializable;publicclassstudentimplementsSerializable{privateint sid;privateStringname;publicintgetSid() {returnsid; ...
