Question

我试图调试为什么我向AWS Lambda GateAPI的输入json无法解析JSON正文。不得不多次部署，在AWS上部署CloudFormation模板，然后进行调试，我在本地计算机中配置了AWS SAM以模拟无服务器环境。是代码

以下是代码和

的摘录

public class FetchByChangeIdLambda implements RequestHandler<RequestBody, String> {

    private static final String searchEndPoint=System.getenv("SEARCH_ENDPOINT");;
    @Override
    public String handleRequest(RequestBody changeId, Context context) {

        System.out.println("Did it even entered"+" "+changeId.getChangeId());       
        if(context.getLogger()!=null) {
        LambdaLogger lambdaLogger = context.getLogger();
        lambdaLogger.log("Search End Point is" + " " + searchEndPoint);
        lambdaLogger.log(String.format("Starting Search for Change Id,%s", changeId.getChangeId()));
        return GetResponseByChangeId.getResponse(searchEndPoint, changeId.getChangeId(), lambdaLogger);


        }

            return GetResponseByChangeId.getResponse(searchEndPoint, changeId.getChangeId(), null);

    }

POJO：

public class RequestBody {


    private String changeId;

    public RequestBody(String changeId) {
        this.changeId=changeId;
    }

    public RequestBody() {

    }
    public String getChangeId() {
        return changeId;
    }

    public void setChangeId(String changeId) {
        this.changeId = changeId;
    }
}

AWS本地SAM调试：

sam local -event event.json api -m GET -b“” | sam local invoke -d 5858 MicroserviceGetGateway

event.json的内容

{ 
  "changeId":1212
}

错误消息：

Jackson databind 2.6.7.1 jar不会使用AWS Lambda Gateway将我的JSON解析为POJO
