Question

我是无服务器框架的新手。我试图用maven，spring，hibernate，jpa，mysql和无服务器来测试一个简单的应用程序。

由于restApi工作正常，但是当我在无服务器终端中调用该函数时，信息变为null，因为没有从db获取信息。这是我的代码

的persistence.xml

        </properties>

我的处理程序类

    public class Handler implements RequestHandler<Map<String, Object>, ApiGatewayResponse> {

    private static final Logger logger = LoggerFactory.getLogger(TestService.class);

    @Autowired
    private IBaseService service;

    @Override
    public ApiGatewayResponse handleRequest(Map<String, Object> input, Context context) {
        List<Wizard> prueba = service.getWizards();
        Map<String, Wizard> response = new HashMap<>();
        Response responseBody = new Response("success", response);
        try {
            for (Wizard entity : prueba) {
                response.put(entity.getName(), entity);
            }
            responseBody.setInput(response);
        } catch (Exception e) {
            logger.error(e.getMessage(), e);
            responseBody.setMessage("Fail: " + e.getMessage());
        }
        return ApiGatewayResponse.builder().setStatusCode(200).setObjectBody(responseBody)
                .setHeaders(Collections.singletonMap("This is a test", "AWS Lambda & serverless")).build();
    }
}

我的serverless.yml

service: aws-java-maven # NOTE: update this with your service name

provider:
  name: aws
  runtime: java8

  iamRoleStatements:
    - Effect: "Allow"
      Action:
        - "mysql:*"
      Resource: "*"

package:
  artifact: target/hello-dev.jar

functions:
 get-transactions:  
    handler: com.serverless.Handler
