 Data deserialization is one of the most vulnerable links to be exploited by attackers. Attackers use it to steal or destroy server-side data, such as rce attack.
 Before switching the serialization protocol or implementation, the user should fully investigate the security guarantee of target serialization protocol and its framework implementation, and set corresponding security measures in advance (such as setting Black / white list). The Dubbo framework itself cannot guarantee the security of the target serialization mechanism.</p><p>Dubbo 2.7 The official version provides the following serialization protocols:</p><ul><li>Hessian2</li><li>Fastjso [...]

 @Bean public ApplicationConfig applicationConfig() { ApplicationConfig applicationConfig = new ApplicationConfig(); applicationConfig.setName(&#34;dubbo-annotation-consumer&#34;); return applicationConfig; } 虽然实现类似于ProviderConfiguration 和 ConsumerConfiguration 这样的 Spring @Configuration Bean 成本并不高，不过通过 Java Code 的方式定义配置 Bean，或多或少是一种 Hard Code（硬编码）的行为，缺少弹性。
 尽管在 Spring 应用中，可以通过 @Value 或者 Environment 的方式获取外部配置，其代码简洁性以及类型转换灵活性存在明显的不足。因此，Spring Boot 提出了外部化配置（External Configuration）的感念，即通过程序以外的配置源，动态地绑定指定类型。
 随着 Spring Boot / Spring Cloud 应用的流行，开发人员逐渐地接受并且使用 Spring Boot 外部化配置（External Configuration），即通过 application.properties 或者 bootstrap.properties 装配配置 Bean。

 &lt;p>3.0 是下一代 Dubbo 架构的代号。一年前，最开始探索 Reactive Stream 之时，社区也曾有过对 Dubbo 3.0的广泛讨论。而这一次，在云原生大背景下，3.0 代表了更全面的 Dubbo 架构升级，涉及到下一代 RPC 协议、全新的服务治理模型和云原生基础设施适配等。&lt;/p>
 &lt;p>阿里巴巴是参与 Dubbo 3.0 开发建设的主要力量之一，这款始于阿里的开源项目正重新回归阿里内部落地。&lt;/p>
 &lt;p>去年开始，阿里巴巴就已经在逐步推动以 Dubbo 替换其内部的 HSF 框架的工作，通过将 Dubbo 与 HSF 两个框架融为一体，并在此基础上发展出适应云原生架构的 Dubbo 版本。Dubbo 重回阿里巴巴的落地是拥抱社区、拥抱云原生、拥抱标准化的一次很好的实践。&lt;/p>

 &lt;p>3.0 是下一代 Dubbo 架构的代号。一年前，最开始探索 Reactive Stream 之时，社区也曾有过对 Dubbo 3.0的广泛讨论。而这一次，在云原生大背景下，3.0 代表了更全面的 Dubbo 架构升级，涉及到下一代 RPC 协议、全新的服务治理模型和云原生基础设施适配等。&lt;/p>
 &lt;p>阿里巴巴是参与 Dubbo 3.0 开发建设的主要力量之一，这款始于阿里的开源项目正重新回归阿里内部落地。&lt;/p>
 &lt;p>去年开始，阿里巴巴就已经在逐步推动以 Dubbo 替换其内部的 HSF 框架的工作，通过将 Dubbo 与 HSF 两个框架融为一体，并在此基础上发展出适应云原生架构的 Dubbo 版本。Dubbo 重回阿里巴巴的落地是拥抱社区、拥抱云原生、拥抱标准化的一次很好的实践。&lt;/p>
-&lt;p>阿里巴巴内部 Dubbo 3.0 的落地，对社区也是一个重大利好，这一方面有利于阿里巴巴将其在 HSF 上的丰富服务治理经验回馈输出到社区，另一方面也将直接推动 Dubbo 云原生架构的快速演进。除了阿里巴巴之外，包括斗鱼、工商银行、爱奇艺、斗鱼等厂商也都在参与下一代 Dubbo 3.0 的建设。&lt;/p>

 &lt;p>下面列出了 Dubbo 3.0 中的三个重要方向，具体的 Roadmap 将在接下来文章中单独说明：&lt;/p>
 &lt;ul>
 &lt;li>下一代 RPC 协议。新协议将提供更丰富的如 Stream、Flow Control 等内置语义，同时将具有更好的扩展性、网关的友好性等；&lt;/li>

 Dubbo 生态系统 我们建议您将扩展加入到 Dubbo 生态系统。使用这种模式，可以使 Dubbo 的核心仓库更干净，并且可以减少维护工作。更少的代码也可以提高核心仓库的构建速度。
 依赖 要实现您自己的 Dubbo 扩展，通常只需依赖 API jar 就可以满足您的需求。例如：
 <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-serialization-api</artifactId> <version>${dubbo.version}</version> </dependency> Src指导 通常，要实现特殊的扩展，只需要参考开发者指南，实现Dubbo必要的接口和合适的扩展即可。除此之外，还有一些其它的事项需要注意：
- 良好的测试，您需要编写单元测试和冒烟测试以消除潜在的 bug。 没有警告，如有不可避免的警告，请使用 @SuppressWarnings 阻止它，但是请不要乱用。 README。添加必要的自述以说明如何使用扩展，以及需要注意的事项。 许可证：请确保使用Apache License 2.0。  通知社区  提交您的代码到 github。 加入邮件列表（建议）。点击这里查看如何加入邮件列表。 发送一封邮件到 dev@incubator.dubbo.apache.org 通知社区。 通常，发送邮件之后，社区会对您的扩展进行讨论，dubbo 组的管理员会联系您转移您的项目到 dubbo 生态系统。  转移项目到dubbo生态系统  dubbo 组的管理员会请您将您的项目的所有者转让给 dubbo。 dubbo 组的管理员会在 dubbo 组下新建一个项目并邀请您加入到这个项目。 一旦您接受邀请，您可以将您的项目转移到 dubbo 组下的新项目里。 dubbo 组的成员会对
 您的项目进行代码审查。随后，您可以对这些代码进行改进。  "><meta property="og:typ [...]

 数据反序列化是最容易被被攻击者利用的一个环节，攻击者利用它执行 RCE 攻击等窃取或破坏服务端数据，用户在切换序列化协议或实现前，

 应用级别的配置可以为应用或者应用内的服务指定配置，在服务维度上，需要区分提供者和消费者。dubbo.reference.{serviceName}表示作为该服务消费者的配置，dubbo.provider.{servcieName}表示作为该服务提供者的配置。其中注册中心和元数据中心的地址，只能在全局配置中指定，这也是Dubbo2.7中推荐的使用方式。

 异常防御，但不忽略异常 这里讲的异常防御，指的是对非必须途径上的代码进行最大限度的容忍，包括程序上的 BUG，比如：获取程序的版本号，会通过扫描 Manifest 和 jar 包名称抓取版本号，这个逻辑是辅助性的，但代码却不少，初步测试也没啥问题，但应该在整个 getVersion() 中加上一个全函数的 try-catch 打印错误日志，并返回基本版本，因为 getVersion() 可能存在未知特定场景异常，或被其他的开发人员误修改逻辑(但一般人员不会去掉 try-catch)，而如果它抛出异常会导致主流程异常，这是我们不希望看到的。但这里要控制个度，不要随意 try-catch，更不要无声无息的吃掉异常。
 缩小可变域和尽量 final 如果一个类可以成为不变类(Immutable Class)，就优先将它设计成不变类。不变类有天然的并发共享优势，减少同步或复制，而且可以有效帮忙分析线程安全的范围。就算是可变类，对于从构造函数传入的引用，在类中持有时，最好将字段 final，以免被中途误修改引用。不要以为这个字段是私有的，这个类的代码都是我自己写的，不会出现对这个字段的重新赋值。要考虑的一个因素是，这个代码可能被其他人修改，他不知道你的这个弱约定，final 就是一个不变契约。
 降低修改时的误解性，不埋雷 前面不停的提到代码被其他人修改，这也开发人员要随时紧记的。这个其他人包括未来的自己，你要总想着这个代码可能会有人去改它。我应该给修改的人一点什么提示，让他知道我现在的设计意图，而不要在程序里面加潜规则，或埋一些容易忽视的雷，比如：你用 null 表示不可用，size 等于 0 表示黑名单，这就是一个雷，下一个修改者，包括你自己，都不会记得有这样的约定，可能后面为了改某个其它 BUG，不小心改到了这里，直接引爆故障。对于这个例子，一个原则就是永远不要区分 null 引用和 empty 值。
-提高代码的可测性 这里的可测性主要指 Mock 的容易程度，和测试的隔离性。至于测试的自动性，可重复性，非偶然性，无序性，完备性(全覆盖)，轻量性(可快速执行)，一般开发人员，加上 JUnit 等工具的辅助基本都能做到，也能理解它的好处，只是工作量问题。这里要特别强调的是测试用例的单一性(只测目标类本身)和隔离性(不传染失败)。现在的测试代码，过于强调完备性，大量重复交叉测试，看起来没啥坏处，但测试代码越多，维护代价越高。经常出现的问题是，修改一行代码或加一个判断条件，引起 100 多个测试用例不通过。时间一紧，谁有这个闲功夫去改这么多形态各异的测试用例？久而久之，这个测试代码就已经不能真实反应代码现在的状况，很多时候会被迫绕过。最好的情况是，修改一行代码，有且只有一行测试代码不通过。如果修�

  最近一直担心如果 Dubbo 分布式服务框架维护人员增多或变更，会出现质量的下降的问题， 我在想，有没有什么规则是需要大家共同遵守的。根据平时写代码时的一习惯，总结了以下在写代码过程中，尤其是框架代码，要时刻牢记的细节。可能下面要讲的这些，大家都会觉得很简单，很基础，但要做到时刻牢记。在每一行代码中都考虑这些因素，是需要很大耐心的， 大家经常说，魔鬼在细节中，确实如此。
 防止空指针和下标越界 这是我最不喜欢看到的异常，尤其在核心框架中，我更愿看到信息详细的参数不合法异常。这也是一个编写健壮程序的开发人员，在写每一行代码都应在潜意识中防止的异常。基本上要能确保每一次写完的代码，在不测试的情况下，都不会出现这两个异常才算合格。
 保证线程安全性和可见性 对于框架的开发人员，对线程安全性和可见性的深入理解是最基本的要求。需要开发人员，在写每一行代码时都应在潜意识中确保其正确性。因为这种代码，在小并发下做功能测试时，会显得很正常。但在高并发下就会出现莫明其妙的问题，而且场景很难重现，极难排查。

  我们平台的产品越来越多，产品的功能也越来越多。平台的产品为了适应各 BU 和部门以及产品线的需求，势必会将很多不相干的功能凑在一起，客户可以选择性的使用。为了兼容更多的需求，每个产品，每个框架，都在不停的扩展，而我们经常会选择一些扩展的扩展方式，也就是将新旧功能扩展成一个通用实现。我想讨论是，有些情况下也可以考虑增量式的扩展方式，也就是保留原功能的简单性，新功能独立实现。我最近一直做分布式服务框架的开发，就拿我们项目中的问题开涮吧。
 比如：远程调用框架，肯定少不了序列化功能，功能很简单，就是把流转成对象，对象转成流。但因有些地方可能会使用 osgi，这样序列化时，IO 所在的 ClassLoader 可能和业务方的 ClassLoader 是隔离的。需要将流转换成 byte[] 数组，然后传给业务方的 ClassLoader 进行序列化。为了适应 osgi 需求，把原来非 osgi 与 osgi 的场景扩展了一下，这样，不管是不是 osgi 环境，都先将流转成 byte[] 数组，拷贝一次。然而，大部分场景都用不上 osgi，却为 osgi 付出了代价。而如果采用增量式扩展方式，非 osgi 的代码原封不动，再加一个 osgi 的实现，要用 osgi 的时候，直接依赖 osgi 实现即可。
-再比如：最开始，远程服务都是基于接口方法，进行透明化调用的。这样，扩展接口就是， invoke(Method method, Object[] args)，后来，有了无接口调用的需求，就是没有接口方法也能调用，并将 POJO 对象都转换成 Map 表示。因为 Method 对象是不能直接 new 出来的，我们不自觉选了一个扩展式扩展，把扩展接口改成了 invoke(String methodName, String[] parameterTypes, String returnTypes, Object[] args)，导致不管是不是无接口调用，都得把 parameterTypes 从 Class[] 转成 String[]。如果选用增量式扩展，应该是保持原有接口不变，增加一个 GeneralService 接口，里面有一个通用的 invoke() 方法，和其它正常业务上的接口一样的调用方式，扩展接口也不用变，只是 GeneralServiceImpl 的 invoke() 实现会将收到的调用转给目标接口，这样就能将新功能增量到旧功能上，并保持原来结构的简单性。"><m [.

 API 与 SPI 分离 框架或组件通常有两类客户，一个是使用者，一个是扩展者。API (Application Programming Interface) 是给使用者用的，而 SPI (Service Provide Interface) 是给扩展者用的。在设计时，尽量把它们隔离开，而不要混在一起。也就是说，使用者是看不到扩展者写的实现的。
 比如：一个 Web 框架，它有一个 API 接口叫 Action，里面有个 execute() 方法，是给使用者用来写业务逻辑的。然后，Web 框架有一个 SPI 接口给扩展者控制输出方式，比如用 velocity 模板输出还是用 json 输出等。如果这个 Web 框架使用一个都继承 Action 的 VelocityAction 和一个 JsonAction 做为扩展方式，要用 velocity 模板输出的就继承 VelocityAction，要用 json 输出的就继承 JsonAction，这就是 API 和 SPI 没有分离的反面例子，SPI 接口混在了 API 接口中。
 合理的方式是，有一个单独的 Renderer 接口，有 VelocityRenderer 和 JsonRenderer 实现，Web 框架将 Action 的输出转交给 Renderer 接口做渲染输出。

  最近给团队新人讲了一些设计上的常识，可能会对其它的新人也有些帮助，把暂时想到的几条，先记在这里。
 API 与 SPI 分离 框架或组件通常有两类客户，一个是使用者，一个是扩展者。API (Application Programming Interface) 是给使用者用的，而 SPI (Service Provide Interface) 是给扩展者用的。在设计时，尽量把它们隔离开，而不要混在一起。也就是说，使用者是看不到扩展者写的实现的。
 比如：一个 Web 框架，它有一个 API 接口叫 Action，里面有个 execute() 方法，是给使用者用来写业务逻辑的。然后，Web 框架有一个 SPI 接口给扩展者控制输出方式，比如用 velocity 模板输出还是用 json 输出等。如果这个 Web 框架使用一个都继承 Action 的 VelocityAction 和一个 JsonAction 做为扩展方式，要用 velocity 模板输出的就继承 VelocityAction，要用 json 输出的就继承 JsonAction，这就是 API 和 SPI 没有分离的反面例子，SPI 接口混在了 API 接口中。
 合理的方式是，有一个单独的 Renderer 接口，有 VelocityRenderer 和 JsonRenderer 实现，Web 框架将 Action 的输出转交给 Renderer 接口做渲染输出。

 Dubbo 的服务注册中心 目前服务注册中心使用了数据库来保存服务提供者和消费者的信息。注册中心集群不同注册中心也通过数据库来进行同步数据，以感知其它注册中心上提供者的变化。注册中心会在内存中保存一份提供者和消费者数据，数据库不可用时，注册中心独立对外提供服务以保证正常运转，只是拿不到其它注册中心的数据。当数据库恢复时，重试逻辑会将内存中修改的数据写回数据库，并拿到数据库中新数据。
 服务的消费者 服务消费者从注册中心拿到提供者列表后，会保存提供者列表到内存和磁盘文件中。这样注册中心宕机后消费者可以正常运转，甚至可以在注册中心宕机过程中重启消费者。消费者启动时，发现注册中心不可用，会读取保存在磁盘文件中提供者列表。重试逻辑保证注册中心恢复后，更新信息。
