AnnotationConfigApplicationContext已经关闭-在AWS Lambda中

Question

我已经使用spring boot-spring数据启动程序jpa来读取AWS Lambda中的mysql内容。

，当我上传lambda并对其进行测试时-它运行正常。但是过了一会儿-大约30分钟后，我一次又一次收到此错误

org.springframework.context.annotation.AnnotationConfigApplicationContext@3ffc5af1 has been closed already

主处理程序类-由于没有主方法

@Component
@SpringBootApplication
public class LambdaRDSFunction implements RequestHandler<ApiGatewayProxyRequest, ApiGatewayProxyResponse> {

  private static final Gson gson = new GsonBuilder().disableHtmlEscaping().create();
  public static AnnotationConfigApplicationContext ctx;
  public static Thread shutDownHookThread = null;

  static {
    ctx = new AnnotationConfigApplicationContext(RDSReadConfiguration.class);
    if (ctx == null)
      ctx = new AnnotationConfigApplicationContext(RDSReadConfiguration.class);
    else if (!ctx.isActive())
      ctx.start();
    //
    // if (shutDownHookThread == null) {
    // ctx.registerShutdownHook();
    // shutDownHookThread = new Thread(() -> {
    // ctx.close();
    // });
    // getRuntime().addShutdownHook(shutDownHookThread);
    // }
  }
  private LambdaLogger logger;

  public ApiGatewayProxyResponse handleRequest(ApiGatewayProxyRequest apiGatewayProxyRequest, Context context) {
    logger = context.getLogger();
