'No ServletContext set' after calling SpringBootLambdaContainerHandler.getInstance().activateSpringProfiles

從 StreamLambdaHandlerTest 中回報的 update_profile 測試開始，追蹤堆疊追蹤中顯示的 SpringBootLambdaContainerHandler.initialize 和 handleRequest 呼叫。執行重現測試，然後確認啟用測試設定檔會重新載入應用程式上下文，且第二個 /ping 請求會回傳 HTTP 200，而不會出現 No ServletContext 錯誤。

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

Serverless Java Container version: 1.6

Implementations: Spring Boot 2

Framework version: 2.5.3

Frontend service: REST API

Deployment method: SAM

Scenario

I'm trying to reload the Spring profile at runtime by calling SpringBootLambdaContainerHandler.getInstance().activateSpringProfiles("<new-profile-name>")

Expected behavior

The new application context should be reloaded and the new profile applied.

Actual behavior

An IllegalStateException is thrown with message No ServletContext set

Steps to reproduce

Provide code samples we can use to reproduce the issue as part of our integration tests. If there is a public repository for the misbehaving application link to it here

1. Use the mvn archetype:generate command found on the Serverless Container Quick start Spring Boot2 Github page to generate a new project.
2. In the unit test that gets created as part of the project, add the following test case:

    @Test
    public void update_profile() {
        // This will work.
        InputStream requestStream = new AwsProxyRequestBuilder("/ping", HttpMethod.GET)
                .header(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON)
                .buildStream();
        ByteArrayOutputStream responseStream = new ByteArrayOutputStream();

        handle(requestStream, responseStream);

        AwsProxyResponse response = readResponse(responseStream);
        assertNotNull(response);
        assertEquals(Response.Status.OK.getStatusCode(), response.getStatusCode());

        // Now change the profile.
        SpringBootLambdaContainerHandler.getInstance().activateSpringProfiles("test");

        // Try making the call again. Status code 502 will be returned by the server.
        requestStream = new AwsProxyRequestBuilder("/ping", HttpMethod.GET)
                .header(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON)
                .buildStream();
        responseStream = new ByteArrayOutputStream();

        handle(requestStream, responseStream);

        response = readResponse(responseStream);
        assertNotNull(response);
        assertEquals(Response.Status.OK.getStatusCode(), response.getStatusCode());
    }

3. Run the test. It will fail.
