protostuff工具類
編寫一個(gè)SerializationUtil工具類，使用Protostuff實(shí)現(xiàn)序列化：
public class SerializationUtil {
private static Map<Class<?>, Schema<?>> cachedSchema = new ConcurrentHashMap<>();
private static Objenesis objenesis = new ObjenesisStd(true);
private SerializationUtil() {
}
@SuppressWarnings("unchecked")
private static <T> Schema<T> getSchema(Class<T> cls) {
Schema<T> schema = (Schema<T>) cachedSchema.get(cls);
if (schema == null) {
schema = RuntimeSchema.createFrom(cls);
if (schema != null) {
cachedSchema.put(cls, schema);
}
}
return schema;
}
@SuppressWarnings("unchecked")
public static <T> byte[] serialize(T obj) {
Class<T> cls = (Class<T>) obj.getClass();
LinkedBuffer buffer = LinkedBuffer.allocate(LinkedBuffer.DEFAULT_BUFFER_SIZE);
try {
Schema<T> schema = getSchema(cls);
return ProtostuffIOUtil.toByteArray(obj, schema, buffer);
} catch (Exception e) {
throw new IllegalStateException(e.getMessage(), e);
} finally {
buffer.clear();
}
}
public static <T> T deserialize(byte[] data, Class<T> cls) {
try {
T message = (T) objenesis.newInstance(cls);
Schema<T> schema = getSchema(cls);
ProtostuffIOUtil.mergeFrom(data, message, schema);
return message;
} catch (Exception e) {
throw new IllegalStateException(e.getMessage(), e);
}
}
}
以上了使用 Objenesis 來實(shí)例化對(duì)象嚣潜，它是比 Java 反射更加強(qiáng)大膀跌。
注意：如需要替換其它序列化框架，只需修改SerializationUtil即可。當(dāng)然朝氓，更好的實(shí)現(xiàn)方式是提供配置項(xiàng)來決定使用哪種序列化方式径荔。
