Hessian2 serialization supports this feature, making it easier for us to reconstruct the Dubbo interface
We know that the default serialization method of dubbo RPC is Hessian2. First look at the following Hessian2 serialization test code. // ——- MyDto ——- import lombok.Data; import lombok.experimental.Accessors; import java.io.Serializable; @Data @Accessors(chain = true) public class MyDto implements Serializable { private String id; private String name; private Integer num; } // —— Hessian2 serialization […]
