我有一个Spring Boot 应用程序，我试图部署在AWS lambda。
我添加了StreamLambdaHandler作为处理程序类
公共类StreamLambda处理程序实现请求流处理程序{

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，我得到了下面的异常com.amazonaws.serverless.exceptions.ContainerInitializationException：无法在20000 ms超时内初始化框架
因此我更新了lambda配置，将超时设置为5分钟，并在StreamLambdaHandler类的静态块中添加了以下行：LambdaContainerHandler.getContainerConfig（）.setInitializationTimeout（2000000）;
现在，我在线程“Thread-0”java.lang.IllegalArgumentException中看到下面的异常异常：无法找到计时器SPRINGBOOT2_COLD_START
有人能给我指出正确的方向吗？因为我在AWS服务和lambda方面是个新手
