Rust和Java互相调用

Rust和Java互相调用使用 Rust 调用 Java 开发的 Dubbo 服务。1 前置条件安装 Rust 开发环境安装 protoc 工具安装 Java 开发环境2 运行示例 Java 版本的 Dubbo provider

Java 版本的 Dubbo provider 示例源码见https://github.com/apache/dubbo-samples/tree/master/3-extensions/protocol/dubbo-samples-triple。

Clone 源代码、编译构建，并运行 provider：

$ # clone 源代码 $ git clone https://github.com/apache/dubbo-samples.git $ cd dubbo-samples/dubbo-samples-triple/ $ # 构建 $ mvn clean compile package -DskipTests $ # 运行 provider $ java -Dprovider.port=8888 -jar ./target/dubbo-samples-triple-1.0-SNAPSHOT.jar # ……省略部分日志 Dubbo triple stub server started, port=8888

3 运行 Rust 版本的 Dubbo consumer

Rust 版本的 Dubbo consumer 示例源码见https://github.com/apache/dubbo-rust/tree/main/examples/greeter。

Clone 源代码、编译构建，并运行 consumer：

$ # clone 源代码 $ git clone https://github.com/apache/dubbo-rust.git $ cd dubbo-rust/examples/greeter/ $ # 构建 $ cargo build $ # 运行 consumer，调用provider $ ../../target/debug/greeter-client # unary call Response: GreeterReply { message: "hello, dubbo-rust" } # client stream client streaming, Response: GreeterReply { message: "hello client streaming" } # bi stream parts: Metadata { inner: {"content-type": "application/grpc", "date": "Wed, 28 Sep 2022 23:54:56 GMT"} } reply: GreeterReply { message: "server reply: \"msg1 from client\"" } reply: GreeterReply { message: "server reply: \"msg2 from client\"" } reply: GreeterReply { message: "server reply: \"msg3 from client\"" } trailer: Some(Metadata { inner: {"grpc-message": "poll trailer successfully.", "grpc-accept-encoding": "gzip,identity", "content-type": "application/grpc", "grpc-status": "0"} }) # server stream parts: Metadata { inner: {"content-type": "application/grpc", "date": "Wed, 28 Sep 2022 23:54:56 GMT"} } reply: GreeterReply { message: "msg1 from server" } reply: GreeterReply { message: "msg2 from server" } reply: GreeterReply { message: "msg3 from server" } trailer: Some(Metadata { inner: {"content-type": "application/grpc", "grpc-message": "poll trailer successfully.", "grpc-accept-encoding": "gzip,identity", "grpc-status": "0"} })
