# generic 样例中 Java client -> Go server 失败，而 Go->Go / Go->Java 正常 ## 问题描述 在 `dubbo-go-samples/generic` 中，按当前 README 的官方方式测试时： - `Go client -> Go server` 可以正常通过 - `Go client -> Java server` 可以正常通过 - 但 `Java client -> Go server` 失败 因此 `generic` 不能记为整体通过。 ## 测试环境 - `dubbo-go-samples` 的 Go 依赖通过 `go.mod replace` 指向本地 `dubbo-go-3.3.2` - Java 环境：JDK 17 ## 复现步骤 ### 1. 启动 Go server ```bash cd generic/go-server/cmd go run . ``` ### 2. 验证 Go client -> Go server ```bash cd generic/go-client/cmd go run . ``` 结果： ```text All generic call tests passed ``` ### 3. 验证 Java client -> Go server ```bash cd generic/java-client mvn clean compile exec:java -Dexec.mainClass="org.apache.dubbo.samples.ApiTripleConsumer" ``` ## 实际结果 Java client 调 Go server 失败，关键表现为： ```text [FAIL] GetUser1(String): DEADLINE_EXCEEDED [FAIL] GetUser2(String, String): DEADLINE_EXCEEDED [FAIL] GetUser3(int): DEADLINE_EXCEEDED [FAIL] GetUser4(int, String): DEADLINE_EXCEEDED [FAIL] GetOneUser(): DEADLINE_EXCEEDED [FAIL] GetUsers(String[]): DEADLINE_EXCEEDED [FAIL] GetUsersMap(String[]): DEADLINE_EXCEEDED [FAIL] QueryAll(): DEADLINE_EXCEEDED [FAIL] QueryUser(User): DEADLINE_EXCEEDED [FAIL] QueryUsers(User[]): DEADLINE_EXCEEDED ``` 在较新的 JDK 下，还会先看到 Java 侧异常： ```text java.lang.reflect.InaccessibleObjectException ``` 或： ```text WARNING: Illegal reflective access by ... hessian-lite ... ``` ## 预期结果 按 README 的说明，`generic` 样例中的 Go/Java 泛化调用都应能正常完成，不应只通过 `Go -> Go` 和 `Go -> Java`。 ## 补充说明 ### Go -> Java 正常 启动 Java server 后： ```bash cd generic/java-server mvn clean compile exec:java -Dexec.mainClass="org.apache.dubbo.samples.ApiProvider" ``` 再运行： ```bash cd generic/go-client/cmd go run . ``` 结果仍然是： ```text All generic call tests passed ``` 说明： - Go client -> Java server 是正常的 ### 当前现象更像是定向问题 当前只在 `Java client -> Go server` 这条链路上稳定失败。 ## 建议排查方向 - Java generic client 与 Go generic server 的兼容性 - Hessian2 / generic invocation 在 Java -> Go 路径上的序列化与解码 - `User` 结构中 `time.Time` 等字段的跨语言兼容性 -- This is an automated message from the Apache Git Service.
