Pivotal GemFire：Spring Data GemFire 中的 PDX 序列化程序配置
Pivotal GemFire: PDX serializer config in Spring Data GemFire
我创建了一个带有 2 个定位器、2 个缓存服务器和一个 "Customer" REPLICATE 区域的 GemFire 集群。 （域对象 class 在服务器启动期间放置在 classpath 中）。
我能够 运行 一个 Java 程序（Peer）来加载集群中的 "Customer" 区域。现在我们想转到 Spring Data GemFire，我不确定如何配置 PDX 序列化和获取...

这里有几个选项，以及一些建议。
1) 首先，我不会使用 Pivotal GemFire 的 o.a.g.pdx.ReflectionBasedAutoSerializer。相反，SDG 基于 Spring 数据的 映射基础设施（即 o.s.d.g.mapping.MappingPdxSerializer）具有更强大的 PdxSerializer 实施。
此外，SDG 的 MappingPdxSerializer 允许您 register custom PdxSerializer's 在实体 field/property 个案基础上。想象一下，如果您的 Customer class 引用了一个复杂的 Address class 并且 class 有特殊的序列化需求。
此外，SDG 的 MappingPdxSerializer 可以处理瞬态和只读属性。
最后，您不必乱用任何 fussy/complex 正则表达式来正确识别需要序列化的应用程序域模型类型。
2) 其次，您可以像这样简单地利用 Spring 的 JavaConfig along with SDG's new Annotation-based configuration model to configure Pivotal GemFire PDX Serialization...
@SpringBootApplication
@PeerCacheApplication
@EnablePdx(..)
class MySpringBootApacheGeodeApplication {
...
}
即使用SDG@EnablePdx注解。
有关上面#1 和#2 的更多详细信息可用 here and here。
当然，后者更适用于使用Pivotal GemFire 9.x+和Spring Data GemFire 凯 (2.0+)。从您的 XML 配置（即 com.gemstone.gemfire 包）中 com.gemstone.gemfire.pdx.ReflectionBasedAutoSerializer 配置中的包来看，您似乎正在使用 Pivotal GemFire 8.2.x 与 Spring 数据 GemFire Ingalls（或 1.9.x .RELEASE), 也许?
但是，如果您坚持，或被要求使用XML进行配置，那么您可以执行以下操作...
<beans ...>
<bean id="mappingPdxSerializer" class="org.springframework.data.gemfire.mapping.MappingPdxSerializer"/>
<gfe:cache pdx-serializer-ref="mappingPdxSerializer" .../>
</beans>
而且，如果您真的想使用 Pivotal GemFire 的 ReflectionBasedAutoSerializer，那么您可以在 SDG 测试套件中找到它的使用示例。对于 instance.
我在我的 spring-gemfire-test project/repo (which is quite a mess and I don't maintain this repo much anymore, as a warning). Examples here, using Java configuration with GemFire's API here, here, here which also shows the use SDG MappingPdxSerializer 中也有更多示例（通过比较），依此类推。我的回购协议中有很多例子。
希望对您有所帮助！
干杯，

我在我的 spring-gemfire-test project/repo (which is quite a mess and I don't maintain this repo much anymore, as a warning). Examples here, using Java configuration with GemFire's API here, here, here which also shows the use SDG MappingPdxSerializer 中也有更多示例（通过比较），依此类推。我的回购协议中有很多例子。
