How Java uses Hessian serialization and deserialization

Hessian is a lightweight RPC (Remote procedure call) framework based on Java. It uses binary to serialize and deserialize, providing a simple and efficient way to transmit Java objects across the network. The main features of the Hessian framework include: 1. Easy to use: The Hessian framework only requires one line of code to achieve service publishing and invocation. 2. Cross platform: Hessian supports interoperability between different programming languages and can communicate between Java and other languages that support the Hessian protocol. 3. Efficient performance: Hessian uses binary for serialization and deserialization, which can reduce network transmission and storage costs and improve system performance. The following is an introduction to commonly used methods in the Hessian framework and Java sample code: 1. Service release: Hessian provides a HessianServlet class for publishing Hessian services. It is necessary to inherit the HessianServlet and implement the corresponding business interface. public class MyHessianServlet extends HessianServlet { public MyHessianServlet() { super(); } //Methods for implementing service interfaces public String sayHello(String name) { return "Hello, " + name; } } 2. Service consumption: Hessian provides the HessianProxyFactory class for creating Hessian proxy objects and obtaining the results of the service through remote calls. public class MyHessianClient { public static void main(String[] args) throws MalformedURLException { String URL=“ http://localhost:8080/hessian The URL address of the Hessian service HessianProxyFactory factory = new HessianProxyFactory(); MyService service=(MyService) factory. create (MyService. class, URL)// Create a Hessian proxy object String result=service. sayHello ("Alice")// Calling service methods System.out.println(result); } } 3. Dependency Configuration: To use Hessian in the Maven project, it is necessary to add the corresponding dependency configuration in the pom.xml file: <dependencies> <dependency> <groupId>com.caucho</groupId> <artifactId>hessian</artifactId> <version>4.0.63</version> </dependency> </dependencies> The above is a brief introduction to the Hessian framework and Java sample code for commonly used methods. To use Hessian for serialization and deserialization, you first need to publish Hessian services, and then make remote calls through Hessian proxy objects to obtain the results of the services. Please configure and code according to actual requirements and project structure.
