Spring Boot 应用程序的 AWS Lambda 超时问题

Question

我有一个 spring boot 应用程序，我试图在 AWS lambda 上部署它。

我将 StreamLambdaHandler 添加为处理程序类

公共类 StreamLambdaHandler 实现 RequestStreamHandler {

private static SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;

static {
    try {
        //handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(SituationalFlexibilityApp.class);

        // For applications that take longer than 10 seconds to start, use the async builder:

         handler = new SpringBootProxyHandlerBuilder<AwsProxyRequest>()
                            .defaultProxy()
                            .asyncInit()
                            .springBootApplication(SituationalFlexibilityApp.class)
                            .buildAndInitialize();

        // we use the onStartup method of the handler to register our custom filter
        handler.onStartup(servletContext -> {
            FilterRegistration.Dynamic registration = servletContext.addFilter("CognitoIdentityFilter",CognitoIdentityFilter.class);
            registration.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), true, "/*");
        });
    } catch (ContainerInitializationException e) {
        // if we fail here. We re-throw the exception to force another cold start
        e.printStackTrace();
        throw new RuntimeException("Could not initialize Spring Boot application", e);
    }
}

public StreamLambdaHandler() {
    Timer.enable();
}
 

/*
 * public StreamLambdaHandler() throws ContainerInitializationException {
 * 
 * handler = new SpringBootProxyHandlerBuilder() .defaultProxy() .asyncInit()
 * .springBootApplication(SlowApplication.class) .buildAndInitialize(); }
 */

@Override
public void handleRequest(InputStream input, OutputStream output, Context context) throws IOException {
    handler.proxyStream(input, output, context);

}

当我在 AWS lambda 上测试它时，我得到以下异常 com.amazonaws.serverless.exceptions.ContainerInitializationException：无法在 20000 毫秒超时内初始化框架

所以我更新了 lambda 配置，超时时间为 5 分钟，并在 StreamLambdaHandler 类的静态块中添加了以下行 LambdaContainerHandler.getContainerConfig().setInitializationTimeout(2000000);

现在，我看到以下异常 线程“Thread-0”中的异常 java.lang.IllegalArgumentException：找不到计时器 SPRINGBOOT2_COLD_START

有人能给我指出正确的方向吗，因为我是 AWS 服务和 lambda 的菜鸟

注释掉下面的代码后我没有看到这个错误StreamLambdaHandler方法

// Timer.enable();
