1. TeammateManager 通过 config.json 维护团队名册。
|
||||
|
||||
```python
|
||||
class TeammateManager:
|
||||
def __init__(self, team_dir: Path):
|
||||
self.dir = team_dir
|
||||
self.dir.mkdir(exist_ok=True)
|
||||
self.config_path = self.dir / "config.json"
|
||||
self.config = self._load_config()
|
||||
self.threads = {}
|
||||
```java
|
||||
// src/main/java/io/mybatis/learn/s09/TeammateManager.java
|
||||
public class TeammateManager {
|
||||
private final ChatModel chatModel;
|
||||
private final MessageBus bus;
|
||||
private final Path configPath;
|
||||
private final ObjectMapper mapper = new ObjectMapper();
|
||||
private Map<String, Object> config;
|
||||
// Python用threading.Thread + dict; Java用ConcurrentHashMap天然线程安全
|
||||
private final Map<String, Thread> threads = new ConcurrentHashMap<>();
|
||||
|
||||
public TeammateManager(ChatModel chatModel, MessageBus bus, Path teamDir) {
|
||||
this.chatModel = chatModel;
|
||||
this.bus = bus;
|
||||
this.configPath = teamDir.resolve("config.json");
|
||||
Files.createDirectories(teamDir);
|
||||
this.config = loadConfig();
|
||||
}
|
||||
```
|

|

2. `spawn()` 创建队友并在线程中启动 agent loop。
|
||||
|
||||
```python
|
||||
def spawn(self, name: str, role: str, prompt: str) -> str:
|
||||
member = {"name": name, "role": role, "status": "working"}
|
||||
self.config["members"].append(member)
|
||||
self._save_config()
|
||||
thread = threading.Thread(
|
||||
target=self._teammate_loop,
|
||||
args=(name, role, prompt), daemon=True)
|
||||
thread.start()
|
||||
return f"Spawned teammate '{name}' (role: {role})"
|
||||
```java
|
||||
// Python用threading.Thread; Java用Thread.startVirtualThread()虚拟线程
|
||||
public synchronized String spawn(String name, String role, String prompt) {
|
||||
Map<String, Object> member = new LinkedHashMap<>();
|
||||
member.put("name", name);
|
||||
member.put("role", role);
|
||||
member.put("status", "working");
|
||||
((List<Map<String, Object>>) config.get("members")).add(member);
|
||||
saveConfig();
|
||||
|
||||
// 虚拟线程：轻量级，由JVM调度，不占用OS线程
|
||||
Thread thread = Thread.startVirtualThread(
|
||||
() -> teammateLoop(name, role, prompt));
|
||||
threads.put(name, thread);
|
||||
return "Spawned '" + name + "' (role: " + role + ")";
|
||||
}
|
||||
```
|
||||
|
||||
3. MessageBus: append-only 的 JSONL 收件箱。`send()` 追加一行; `read_inbox()` 读取全部并清空。
|
||||
|
||||
```python
|
||||
class MessageBus:
|
||||
def send(self, sender, to, content, msg_type="message", extra=None):
|
||||
msg = {"type": msg_type, "from": sender,
|
||||
"content": content, "timestamp": time.time()}
|
||||
if extra:
|
||||
msg.update(extra)
|
||||
with open(self.dir / f"{to}.jsonl", "a") as f:
|
||||
f.write(json.dumps(msg) + "\n")
|
||||
```java
|
||||
// src/main/java/io/mybatis/learn/core/team/MessageBus.java
|
||||
// Python靠GIL隐式保证线程安全; Java用synchronized显式保证
|
||||
public class MessageBus {
|
||||
private final Path inboxDir;
|
||||
private final ObjectMapper mapper = new ObjectMapper();
|
||||
|
||||
def read_inbox(self, name):
|
||||
path = self.dir / f"{name}.jsonl"
|
||||
if not path.exists(): return "[]"
|
||||
msgs = [json.loads(l) for l in path.read_text().strip().splitlines() if l]
|
||||
path.write_text("") # drain
|
||||
return json.dumps(msgs, indent=2)
|
||||
public synchronized String send(String sender, String to, String content,
|
||||
String msgType, Map<String, Object> extra) {
|
||||
Map<String, Object> msg = new LinkedHashMap<>();
|
||||
msg.put("type", msgType);
|
||||
msg.put("from", sender);
|
||||
msg.put("content", content);
|
||||
msg.put("timestamp", System.currentTimeMillis() / 1000.0);
|
||||
if (extra != null) msg.putAll(extra);
|
||||
|
||||
Path inbox = inboxDir.resolve(to + ".jsonl");
|
||||
Files.writeString(inbox, mapper.writeValueAsString(msg) + "\n",
|
||||
StandardOpenOption.CREATE, StandardOpenOption.APPEND);
|
||||
return "Sent " + msgType + " to " + to;
|
||||
}
|
||||
|
||||
public synchronized List<Map<String, Object>> readInbox(String name) {
|
||||
Path inbox = inboxDir.resolve(name + ".jsonl");
|
||||
if (!Files.exists(inbox)) return List.of();
|
||||
List<Map<String, Object>> messages = new ArrayList<>();
|
||||
for (String line : Files.readAllLines(inbox)) {
|
||||
if (!line.isBlank())
|
||||
messages.add(mapper.readValue(line, new TypeReference<>() {}));
|
||||
}
|
||||
Files.writeString(inbox, ""); // drain
|
||||
return messages;

4. 每个队友在每次 LLM 调用前检查收件箱, 将消息注入上下文。
