Tars Proxy

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

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

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

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

Add tars plugin in gateway#

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

        <!-- apache shenyu tars plugin start-->        <dependency>            <groupId>org.apache.shenyu</groupId>            <artifactId>shenyu-spring-boot-starter-plugin-tars</artifactId>            <version>${project.version}</version>        </dependency>
        <dependency>            <groupId>com.tencent.tars</groupId>            <artifactId>tars-client</artifactId>            <version>1.7.2</version>        </dependency>        <!-- apache shenyu tars plugin end-->
  • Restart your gateway service.

Tars service access gateway#

Please refer to： shenyu-examples-tars

  1. In the microservice built by Tars, add the following dependencies:
        <dependency>            <groupId>org.apache.shenyu</groupId>            <artifactId>shenyu-spring-boot-starter-client-tars</artifactId>            <version>${shenyu.version}</version>        </dependency>
  1. Add the following configuration to the application.yaml configuration file:
shenyu:  register:    registerType: http #zookeeper #etcd #nacos #consul    serverLists: http://localhost:9095 #localhost:2181 #http://localhost:2379 #localhost:8848    props:      username: admin      password: 123456  client:    tars:      props:        contextPath: /tars        appName: tars        port: 21715        host: 192.168.41.103
  1. Add @ShenyuTarsService Annotation on the tars service interface implementation class and @ShenyuTarsClient on the method, start your service provider, and register successfully. In the background management system, enter PluginList -> rpc proxy -> tars, you will see the automatic registration of selectors and rules information.

Example:

    @TarsServant("HelloObj")    @ShenyuTarsService(serviceName = "ShenyuExampleServer.ShenyuExampleApp.HelloObj")    public class HelloServantImpl implements HelloServant {        @Override        @ShenyuTarsClient(path = "/hello", desc = "hello")        public String hello(int no, String name) {            return String.format("hello no=%s, name=%s, time=%s", no, name, System.currentTimeMillis());        }            @Override        @ShenyuTarsClient(path = "/helloInt", desc = "helloInt")        public int helloInt(int no, String name) {            return 1;        }    }

User Request#

You can request your tars 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/tars/hello .
