中文标题【MessagePack Java 0.6.X 快速开始指南】
|
||||
|
||||
WARNING: 0.6.x 版本的 MessagePack 已经过期被淘汰了。如果你现在开始使用 MessagePack 话，请不要使用这个版本。
|
||||
我们再这里保留 0.6.x 版本的内容主要用于参考用途。
|
||||
|
||||
最新的 MessagePack 版本请参考: https://github.com/msgpack/msgpack-java 中的项目源代码。
|
||||
|
||||
TIP: MessagePack 中文文档请参考： http://docs.ossez.com/messagepack-docs/index.html
|
||||
|
||||
TIP: MessagePack 测试和示例源代码： https://github.com/cwiki-us-demo/serialize-deserialize-demo-java
|
||||
|
||||
|
||||
这个指南提供了使用 msgpack-java 的快速指南。在开始的时候，我们将会介绍如何安装 msgpack-java，然后将会运行如何使用 msgpack 来对对象序列化/反序列化（serialize/deserizalize）对象。
|
||||
|
||||
== 安装
|
||||
你可以使用下面 2 种方法来安装 msgpack-java —— 从 maven 下载或者直接构建 jar 包。
|
||||
|
||||
=== 从 Maven2 仓库中进行安装
|
||||
MessagePack 针对 Java 的使用已经发布到 Maven 的中央仓库中（Maven Central Repository）。你可以使用下面的参数来配置你项目的 pom.xml 文件。
|
||||
|
||||
[source,xml]
|
||||
----
|
||||
<dependency>
|
||||
<groupId>org.msgpack</groupId>
|
||||
<artifactId>msgpack</artifactId>
|
||||
<version>${msgpack.version}</version>
|
||||
</dependency>
|
||||
----
|
||||
你需要将 ${msgpack.version} 替换为当前的 MessagePack 版本，有关可以使用的具体版本你可以访问 http://repo1.maven.org/maven2/org/msgpack/msgpack/ 中的版本。
|
||||
|
||||
请注意，在 0.6.x 版本中最新的版本只更新到 0.6.12。
|
||||
|
||||
=== 从 git 仓库中进行安装
|
||||
你可以从代码仓库中获得最新的代码。
|
||||
|
||||
[source]
|
||||
----
|
||||
$ git clone git@github.com:msgpack/msgpack-java.git
|
||||
$ cd msgpack-java
|
||||
$ mvn package
|
||||
----
|
||||
|
||||
使用上面的代码进行编译后u，你将会在 msgpack-java/target 目录中得到 msgpack.jar 包。
|
||||
|
||||
同时你也需要 https://code.google.com/p/json-simple/ 和 https://github.com/jboss-javassist/javassist 来让 msgpack.jar 可以在项目中使用。否则你将会收到 NoClassDefFoundError 错误。
|
||||
|
||||
== 如何使用
|
||||
下面是如何使用的示例代码。
|
||||
|
||||
=== 使用一个消息打包（message-packable）类
|
||||
使用注解 '_@Message_' 来让你可以序列化你自己类中对象的 public 字段。
|
||||
|
||||
本代码可以在 https://github.com/cwiki-us-demo/messagepack-6-demo-java/blob/master/src/test/java/com/insight/demo/msgpack/MessagePack6Object.java 中下载到本地后进行编译测试。

如果你希望按照顺序序列化多个对象的话，你可以使用 '_Packer_' 和 '_Unpacker_' 多个对象。
|
||||
|
||||
这是因为 '_MessagePack.write(Object)_' 和 '_read(byte[])_' 实际上每次都调用创建了 '_Packer_' 和 '_Unpacker_' 对象。
|
||||
|
||||
为了使用 '_Packer_' 和 '_Unpacker_' 对象，请调用 '_createPacker(OutputStream)_' 和 '_createUnpacker(InputStream)_'。

=== 多种类型变量的序列化和反序列化（serialization/deserialization）

类 '_Packer/Unpacker_' 允许序列化和反序列化多种类型的变量，如后续程序所示。这个类启用序列化和反序列化多种类型的变量和序列化主要类型变量以及包装类，'_String_' 对象，

'_byte[]_' 对象，'_ByteBuffer 对象等的方法相似。

----
|
||||
|
||||
方法 '_Packer#write()_' 允许序列化多种类型的数据。
|
||||
|
||||
类 '_Unpacker_' 针对反序列化二进制数据为主要变量，提供了一个反序列化方法。例如，你希望将二进制数据反序列化为 '_boolean_' (或者 '_int_') 数据类型，你可以使用 '_Unpacker_' 中的 '_readBoolean_' (或者 '_readInt_') 方法。
|
||||
|
||||
'_Unpacker_' 同时也为参考变量提供了一个读取的方法。这个方法允许为一个参考变量从二进制数据中进行反序列化。参考变量的定义为你将类型指定为一个参数。
|
||||
例如，你希望反序列化二进制数据到 '_String_' (或者 '_byte[]_') 对象，你必须在调用 '_read(String.class)_' (或者 '_read(byte[].class)_') 方法的时候定义描述。
|
||||
|
||||
== List, Map 对象的序列化和反序列化（serialization/deserialization）
|
||||
为了序列化原生的容器对象例如 '_List_' 和 '_Map_' 对象，你必须使用 '_Template_'。
|
||||
|
||||
'_Template_' 对象是 serializer 和 deserializer 的配对。例如，为了序列化一个 '_List_' 对象，在 '_List_' 对象中 '_Integer_' 对象为元素，你可以使用下面的方法来创建一个模板对象（Template object）。
|
||||
|
||||

|
||||
----
|
||||
Template listTmpl = Templates.tList(Templates.TInteger);

||||
----
|
||||
|

类 '_tList_'， '_TInteger_' 是静态方法，字段为 '_Templates_'。

一个 '_List 和 '_Map_' 对象的用例如下显示：

|

|

=== 不使用注解（annotations）来序列化
|
||||
如果你不能添加 @Message 到你的定义对象中但是你还是希望进行序列化。你可以使用 register 方法来在类中启用序列化对象。
|
||||
|
||||
如下的代码所示：
|
||||
|
||||
[source,java]
|
||||
----
|
||||
MessagePack msgpack = new MessagePack();
|
||||
msgpack.register(MyMessage2.class);
|
||||
----
|
||||
|
||||
例如，如果 MyMessage2 类被包含到了外部的库中了。你没有办法比较容易的编辑源代码，添加 '_@Message_' 到源代码中。
|
||||
|
||||
register 方法能够允许为 MyMessage2 自动创建一个 serializer 和 deserializer 对。
|
||||
|
||||
你可以在执行方面后序列化对象 MyMessage2。
|
||||
|
||||
=== 可选字段
|
||||
你可添加一个新的字段来保持可用性。在新字段中使用 '_@Optional_' 注解。
|
||||
|
||||
[source,java]
|
||||
----
|
||||
@Message
|
||||
public static class MyMessage {
|
||||
public String name;
|
||||
public double version;
|
||||
|
||||
// new field
|
||||
@Optional
|
||||
public int flag = 0;
|
||||
}
|
||||
----
|
||||
|
||||
如果你尝试反序列化老版本数据的话，可选字段将会被忽略。
|
||||
|
||||
=== 动态类型
|
||||
我们知道 Java 是一个静态类型的语言。通过输入 '_Value_' MessagePack能够实现动态的特性。
|
||||
|
||||
'_Value_' 有方法来检查自己的类型（'_isIntegerType()_', '_isArrayType()_', 等...)，同时也转换为自己的类型 ('_asStringValue()_', '_convert(Template)_'）。
