Apache Thrift is an interface definition language (IDL) and binary transport protocol invented at Facebook. It allows you to specify APIs by defining the structs (which are similar to objects in most languages) and exceptions that your service exposes. Thrift interfaces defined in the IDL are used to generate code in a supported language that is then used to manage the RPC calls. Supported languages include C, C++, Python, Ruby, and Java.

package com.packtpub.microservices.ch04.thrift;

import com.packtpub.microservices.ch04.thrift.Message;
import com.packtpub.microservices.ch04.thrift.MessageException;
import com.packtpub.microservices.ch04.thrift.MessageService;
import org.apache.thrift.TException;

import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;
import java.util.stream.Stream;

public class MessageServiceImpl implements MessageService.Iface {

private Map<String, List<Message>> messagesRepository;

MessageServiceImpl() {
// populate our mock repository with some sample messages
messagesRepository = new HashMap<>();
messagesRepository.put("usertwo", Stream.of(
new Message(1234, "userone", "usertwo", "hi"),
            new Message(5678, "userthree", "usertwo", "hi")
        ).collect(Collectors.toList()));
messagesRepository.put("userone", Stream.of(
new Message(1122, "usertwo", "userone", "hi"),
            new Message(2233, "userthree", "userone", "hi")
        ).collect(Collectors.toList()));
}

@Override
public List<Message> inbox(String username) throws TException {
if (!messagesRepository.containsKey(username))
throw new MessageException(100, "Inbox is empty");
        return messagesRepository.get(username);
}
}
