To help us debug your issue fill in the basic information below using the options provided

Serverless Java Container version: 2.0.0-M2

Implementations: Spring Boot 3

Framework version: SpringBoot 3.1.3

Frontend service: HTTP API

Deployment method: Console

Scenario

Attempted to handle async requests in a SpringBoot3 application with JPA dependency.

Expected behavior

Return a 200 response

Actual behavior

502 error from Lambda

Steps to reproduce

Here is an example springboot3 project that can reproduce this issue.
https://github.com/2012160085/aws-serverless-java-container-async-jpa-example
Clone this repo and run main in AsyncJpaApplication.

Problem

While examining the error, I found an issue within the asynchronous dispatch logic of AwsAsyncContext when interacting with Spring's DispatcherServlet.

  • Premature Re-dispatch: Currently, AwsAsyncContext prematurly triggers re-dispatch.
    When handling asynchronous requests with DispatcherServlet, DispatcherServlet'sdoDispatch should be called to complete the initial request. Only after the initial request concludes, should the doDispatch be called again for re-dispatch. However, in the present implementation, this sequence is disrupted. During the processing of the initial request by the doDispatch method, the dispatch method of AwsAsyncContext is invoked, which in turn directly calls the doFilter method for immediate re-dispatch. This leads to premature execution of the re-dispatch before the post-processing logic of doDispatch(which is handling the initial request) is executed.

  • EntityManager Bind Timing Issue: While using Spring JPA, due to the aforementioned issue, an error arises when trying to bind the EntityManager to threadLocal during the preHandle phase of the re-dispatch. This is because the EntityManager is already bound from the initial request, and the post-processing logic meant to unbind it hasn't been executed yet. As a result, attempting to bind it again triggers the following error:

Value [org.springframework.orm.jpa.EntityManagerHolder@38a6ca39] already bound to key [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean@39296cef].

Proposed Solution

To resolve this, I made modifications to the handleRequest function within SpringBootLambdaContainerHandler and dispatch function within AwsAsyncContext.
The snippet for the proposed solution is as follows

protected void handleRequest(HttpServletRequest containerRequest, AwsHttpServletResponse containerResponse, Context lambdaContext) throws Exception {
    // ... [other code]
    doFilter(containerRequest, containerResponse, reqServlet);
    if(requiresAsyncReDispatch(containerRequest)) {
        doFilter(containerRequest, containerResponse, reqServlet);
    }
    // ... [other code]
}
public void dispatch() {
    // ... [other code]
    if (!dispatchStarted.get()) {
        dispatchStarted.set(true);
    } else {
        dispatched.set(true);
    // Removed the line that directly calls doFilter
        notifyListeners(NotificationType.START_ASYNC, null);
    }
    // ... [other code]
}

By ensuring that the post-processing of the initial request is complete and only then re-invoking the doFilter when necessary, we can bypass the issues mentioned above.

If there's an opportunity for this to be reviewed and merged to main, I would be appreciated. If this seems acceptable, I'd like to create a PR.
