Motan Proxy

This document is intended to help the Motan service access the Apache ShenYu gateway. The Apache ShenYu gateway uses the Motan plugin to handle motan service.

Before the connection, start shenyu-admin correctly, start Motan plugin, and add related dependencies on the gateway and Motan application client. Refer to the previous Quick start with Motan .

For details about client access configuration, see Application Client Access Config .

For details about data synchronization configurations, see Data Synchronization Config .

Add motan plugin in gateway#

Add the following dependencies to the gateway's pom.xml file:

        <!-- apache shenyu motan plugin -->        <dependency>            <groupId>org.apache.shenyu</groupId>            <artifactId>shenyu-spring-boot-starter-plugin-motan</artifactId>            <version>${project.version}</version>        </dependency>        <dependency>            <groupId>com.weibo</groupId>            <artifactId>motan-core</artifactId>            <version>1.1.9</version>        </dependency>        <dependency>            <groupId>com.weibo</groupId>            <artifactId>motan-registry-zookeeper</artifactId>            <version>1.1.9</version>        </dependency>        <dependency>            <groupId>com.weibo</groupId>            <artifactId>motan-transport-netty4</artifactId>            <version>1.1.9</version>        </dependency>        <dependency>            <groupId>com.weibo</groupId>            <artifactId>motan-springsupport</artifactId>            <version>1.1.9</version>        </dependency>
  • Restart your gateway service.

Motan service access gateway#

Please refer to: shenyu-examples-motan

  1. In the microservice built by Motan, add the following dependencies:
        <dependency>            <groupId>org.apache.shenyu</groupId>            <artifactId>shenyu-spring-boot-starter-client-motan</artifactId>            <version>${shenyu.version}</version>        </dependency>
  1. Add the following configuration to the application.yaml configuration file:
shenyu:  client:    registerType: http #zookeeper #etcd #nacos #consul    serverLists: http://localhost:9095 #localhost:2181 #http://localhost:2379 #localhost:8848    props:      contextPath: /motan      ipAndPort: motan      appName: motan      port: 8081      nacosNameSpace: ShenyuRegisterCentermotan:  registry:    protocol: zookeeper    address: 127.0.0.1:2181
  1. Add @ShenyuMotanClient annotation to the method of Motan service interface implementation class, start your service provider, after successful registration, go to PluginList -> rpc proxy -> motan in the background management system, you will see automatic registration of selectors and rules information.

Example:

@MotanService(export = "demoMotan:8002")public class MotanDemoServiceImpl implements MotanDemoService {    @Override    @ShenyuMotanClient(path = "/hello")    public String hello(String name) {        return "hello " + name;    }}

User Request#

You can request your motan service by Http. The Apache ShenYu gateway needs to have a route prefix which is the contextPath configured by the access gateway. For example: http://localhost:9195/motan/hello .
