This sample showcases how to invoke Dubbo services asynchronously with the new
-`client`/`server` APIs over the Triple protocol. The client issues both a
regular
-async call (`GetUser`) and a fire-and-forget style call (`SayHello`) while the
-server uses Protobuf serialization to serve Triple requests. Note: This sample
-demonstrates the non-blocking nature of async calls; the response can be
obtained
-through the return value.
+`client`/`server` APIs over the Triple protocol. It demonstrates both Go-to-Go
+and Java-to-Go async interoperability.
-## Run the sample
+## Features
-1. **Start the provider**
+- **Go Client & Server**: Async calls using `client.WithAsync()`
+- **Java Client**: Async calls using `CompletableFuture` API
+- **Java Server**: Async service implementation with `CompletableFuture`
+- **Interoperability**: Java client can call Go server, Go client can call
Java server
+
+## Run Go to Go sample
+
+1. **Start the Go server**
```bash
go run ./async/go-server/cmd/main.go
```
-2. **Start the consumer**
+2. **Start the Go client** (connects to Go server by default)
```bash
go run ./async/go-client/cmd/main.go
```
The client prints "non-blocking before async callback resp: do something ... "
and "test end" logs, demonstrating the non-blocking nature of async calls.
+
+## Run Java-Go interoperability sample
+
+This demonstrates **cross-language async calls**:
+
+- **Go client** → **Java server**
+- **Java client** → **Go server**
+
+### Prerequisites
+
+- Java 11 or higher
+- Maven 3.6+
+
+### Build Java modules
+
+From the `async` directory:
+
+```bash
+mvn clean compile
+```
+
+### Test: Go client → Java server
+
+1. **Modify the Go client URL** in `go-client/cmd/main.go`:
+
+ ```go
+ client.WithClientURL("tri://127.0.0.1:50051"),
+ ```
