TarsFramework deployment by Docker

This guide uses Docker to complete the deployment of Tars.[Macos、 Linux]

2. Start TarsFramework in Docker

docker pull tarscloud/framework:latest
docker pull tarscloud/tars-node:latest
docker pull   mysql:5.6
docker network create -d bridge --subnet=172.25.0.0/16 --gateway=172.25.0.1 tars
docker run -d \
--net=tars \
-e MYSQL_ROOT_PASSWORD="root@appinside" \
--ip="172.25.0.2" \
--name=tars-mysql \
mysql:5.6
sleep 30s
docker run -d \
--net=tars \
-e MYSQL_HOST=172.25.0.2 \
-e MYSQL_ROOT_PASSWORD='root@appinside' \
-eREBUILD=false  -eSLAVE=false \
-e INET=eth0 \
--ip="172.25.0.4" \
-p 3000-3001:3000-3001 \
tarscloud/framework
sleep 60s
docker run -d --net=tars --ip="172.25.0.3"  -eWEB_HOST=http://172.25.0.4:3000        tarscloud/tars-node

Note: - P 18600-18700:18600-18700 parameter opens 18600-18700 port for application. You can add more ports if necessary

Quick Start To TarsServer

This guide gives you a quick introduction to Tars in Java through simple server

Dependency configuration

The following configuration needs to be added in pom.xml:

Service development

Tars interface file definition

Tars has its own interface file format. First, we need to define the Tars interface file. Create a new hello.tars file in the resources directory with the following content:

module TestApp
{
	interface Hello
	{
	    string hello(int no, string name);
	};
};
Interface file compilation

Then we need to convert the Tars interface file to the server interface code using the tars-maven-plugin. In the project root directory, execute mvn tars: tars2java to get HelloServant.java, the content is as follows:

@Servant
public interface HelloServant {

	public String hello(int no, String name);
}
Interface implementation

Next we need to implement the generated server interface. Create a new HelloServantImpl.java file, implement the HelloServant.java interface, and expose the service through the @TarsServant annotation, where 'HelloObj' is the servant name, corresponding to the name in the web management platform.

@TarsServant("HelloObj")
public class HelloServantImpl implements HelloServant {

    @Override
    public String hello(int no, String name) {
        return String.format("hello no=%s, name=%s, time=%s", no, name, System.currentTimeMillis());
    }
}
Tars service enabling

Finally, add @EnableTarsServer annotation in the spring boot startup class QuickStartApplication to enable Tars service:

@SpringBootApplication
@EnableTarsServer
public class QuickStartApplication {
    public static void main(String[] args) {
        SpringApplication.run(QuickStartApplication.class, args);
    }
}
