只需在初始化时注入 DubboCodec 便能使用 Dubbo 协议。 **类型映射与拓展** #### **类型映射**Dubbo 主要使用 Hessian2 序列化协议进行 Payload 的编解码,它最大的特点是自描述序列化类型,即不依赖外部 Schema 或接口定义。序列化过程依赖编程语言类型和 Hessian2 类型之间的映射,以 Go 类型转化为 Java 类型为例:![picture.image](https://p3-volc-community-sign.byteimg.com/tos-cn-i-tlddhu82om/...
我们可能希望 Elasticsearch 直接抛出异常而不是直接索引,这样可以及时发现问题。例如:```jsonPUT es_books/_doc/1{ "title":" how to master elasticsearch"}查看 index mappingGET es_books/_mappi...
