系列化对象
public static <T> byte[] enSeri(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();
}
}
反序列化对象
public static <T> T deSeri(byte[] data, Class<T> cls) {
try {
T message = objenesis.newInstance(cls);
Schema<T> schema = getSchema(cls);
ProtostuffIOUtil.mergeFrom(data, message, schema);

序列化List集合
private static <T> byte[] enSeriList(List<T> list) throws RuntimeException, IOException {
if (list == null || list.size() == 0) {
throw new RuntimeException("集合不能为空!");
}
@SuppressWarnings("unchecked")

ByteArrayOutputStream out = new ByteArrayOutputStream();
ProtostuffIOUtil.writeListTo(out, list, schema, LinkedBuffer.allocate(LinkedBuffer.DEFAULT_BUFFER_SIZE));
byte[] byteArray = out.toByteArray();
return byteArray;
}
反序列化List集合
private static <T> List<T> deSeriList(byte[] data, Class<T> clazz) throws IOException {
if (data == null || data.length == 0) {
return null;
}
RuntimeSchema<T> schema = RuntimeSchema.createFrom(clazz);
List<T> result = ProtostuffIOUtil.parseListFrom(new ByteArrayInputStream(data), schema);
