protostuff基本使用
protostuff基于Google Protobuf，好处就是不用自己写.proto文件即可实现对象的序列化与反序列化，下面给出示例代码。
程序代码
User.java
package cn.xpleaf.pojo;public class User { private String name; private int age; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } @Override public String toString() { return "User [name=" + name + ", age=" + age + "]"; }}UserSerializationUtil.java
package cn.xpleaf.protostuff;import com.dyuproject.protostuff.LinkedBuffer;import com.dyuproject.protostuff.ProtostuffIOUtil;import com.dyuproject.protostuff.runtime.RuntimeSchema;import cn.xpleaf.pojo.User;public class UserSerializationUtil { private static RuntimeSchema<User> schema = RuntimeSchema.createFrom(User.class); /** * 序列化方法，将User对象序列化为字节数组 * @param user * @return */ public static byte[] serialize(User user) { // Serializes the {@code message} into a byte array using the given schema return ProtostuffIOUtil.toByteArray(user, schema, LinkedBuffer.allocate(LinkedBuffer.DEFAULT_BUFFER_SIZE)); } /** * 反序列化方法，将字节数组反序列化为User对象 * @param array * @return */ public static User deserialize(byte[] array) { User user = schema.newMessage(); // Merges the {@code message} with the byte array using the given {@code schema} ProtostuffIOUtil.mergeFrom(array, user, schema); return user; }}Demo.java
package cn.xpleaf.protostuff;import cn.xpleaf.pojo.User;public class Demo { public static void main(String[] args) { // 创建User对象 User user = new User(); user.setName("xpleaf"); user.setAge(10); System.out.println("序列化前：" + user); // 使用UserSerializationUtil将user对象序列化 byte[] userBytes = UserSerializationUtil.serialize(user); // 使用UserSerializationUtil反序列化字节数组为user对象 User user2 = UserSerializationUtil.deserialize(userBytes); System.out.println("序列化后再反序列化：" + user2); // 判断值是否相等 System.out.println(user.toString().equals(user2.toString())); }}测试
执行demo代码，输出如下：
序列化前：User [name=xpleaf, age=10]序列化后再反序列化：User [name=xpleaf, age=10]true
