Mango is a high-performance, open-source java RPC framework.
- Supports various serialization protocol, like protostuff, Kryo, Hessian, msgpack, Jackson, Fastjson.
- Supports advanced features like load-balance(random, Round-Robin), HA strategy(Failfast, Failover).
- Supports service discovery services like ZooKeeper or Consul.
- Supports oneway, synchronous or asynchronous invoking.
- Supports SPI extension.
- Easy integrated with Spring Framework 4.x.
The minimum requirements to run the quick start are:
- Add dependencies to pom.
<dependency>
<groupId>com.mindflow</groupId>
<artifactId>mango-core</artifactId>
<version>1.0.1</version>
</dependency>
<dependency>
<groupId>com.mindflow</groupId>
<artifactId>mango-registry-zk</artifactId>
<version>1.0.1</version>
</dependency>
<!-- dependencies blow were only needed for spring integrated -->
<dependency>
<groupId>com.mindflow</groupId>
<artifactId>mango-springsupport</artifactId>
<version>1.0.1</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.3.6</version>
</dependency>
- Create an interface for both service provider and consumer.
public interface DemoService {
void hello(String msg);
String echo(String msg);
Map<String, String> introduce(String name, List<String> hobbies);
}
- Write an implementation, create and start RPC Server.
@Service("demoService")
public class DemoServiceImpl implements DemoService {
@Override
public void hello(String msg) {
System.out.println(msg);
}
@Override
public String echo(String msg) {
return "hello, "+msg;
}
@Override
public Map<String, String> introduce(String name, List<String> hobbies) {
System.out.println("name:"+name + ", hobbies:"+hobbies);
Map<String, String> map = new HashMap<>();
map.put("name", name);
return map;
}
}
