Java リモート メソッド呼び出しのタイムアウト例外 (TimeoutInvocationException) を解決する方法

// 创建远程对象
MyRemoteObject remoteObject = (MyRemoteObject) Naming.lookup("//localhost/MyRemoteObject");

// 设置超时时间为5秒
((RemoteStub) remoteObject).setCallTimeout(5000);

// 调用远程方法
remoteObject.doSomething();

// 创建远程对象
MyRemoteObject remoteObject = (MyRemoteObject) Naming.lookup("//localhost/MyRemoteObject");

// 提交异步调用请求
ExecutorService executorService = Executors.newSingleThreadExecutor();
Future<String> future = executorService.submit(() -> remoteObject.doSomething());

// 设置超时时间为5秒
String result;
try {
    result = future.get(5, TimeUnit.SECONDS);
} catch (InterruptedException | ExecutionException | TimeoutException e) {
    // 处理异常
}

// 创建连接池
PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager();
connectionManager.setMaxTotal(100);    // 设置最大连接数
connectionManager.setDefaultMaxPerRoute(10);    // 设置每个路由的最大连接数

// 创建HttpClient
HttpClient httpClient = HttpClientBuilder.create()
        .setConnectionManager(connectionManager)
        .build();

// 创建远程请求
HttpGet request = new HttpGet("http://localhost:8080/doSomething");

// 发送请求并得到响应
HttpResponse response = httpClient.execute(request);

// 创建HystrixCommand
HystrixCommand<String> command = new HystrixCommand<String>(HystrixCommandGroupKey.Factory.asKey("MyGroup")) {
    @Override
    protected String run() throws Exception {
        // 执行远程方法调用
        return remoteObject.doSomething();
    }

    @Override
    protected String getFallback() {
        // 返回熔断时的默认值
        return "Fallback Value";
    }
};

// 执行命令
String result = command.execute();
