不支持的媒体类型，具有Spring Boot和无服务器

Question

我正在用Spring Boot（无服务器项目）构建应用程序，以部署在AWS Lambda中。我有一个使用application/x-www-form-urlencoded的方法。当我调用localhost415中的方法时，出现：

不支持内容类型'application/x-www-form-urlencoded；charset=utf-8'

我附加了方法代码和yaml配置，我认为问题是无服务器配置，因为这种方法在其他项目（非无服务器）中工作。

方法：

 @PostMapping(name = "/createpayment", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
    public String createPayment(@RequestBody Payload payload) throws StripeException, IOException, MessagingException { 
         ...
 }

YAML：

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: AWS Serverless Sansaru Payments - com.sansarushop.payments::sansaru-payments
Globals:
  Api:
    EndpointConfiguration: REGIONAL


Resources:
  SansaruPaymentsFunction:
    Type: AWS::Serverless::Function
    Properties:
      Handler: com.example.payments.StreamLambdaHandler::handleRequest
      Runtime: java8
      CodeUri: target/example-payments-1.0-SNAPSHOT-lambda-package.zip
      MemorySize: 512
      Policies: AWSLambdaBasicExecutionRole
      Timeout: 30
      Events:
        GetResource:
          Type: Api
          Properties:
            Path: /{proxy+}
            Method: any
      Environment:
        Variables:
          SPRING_PROFILES_ACTIVE: 'prod'

Outputs:
  SansaruPaymentsApi:
    Description: URL for application
    Value: !Sub 'https://${ServerlessRestApi}.execute-api.${AWS::Region}.amazonaws.com/Prod/ping'
    Export:
      Name: ExamplePaymentsApi

谢谢你的帮助！

问题在于mediatype application/x-www-form-urlencoded，Spring Boot不理解RequestBody。因此，如果您想使用，请从方法中删除@RequestBody注释。

@PostMapping(name = "/createpayment", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public String createPayment(@RequestParam Map<String, String> params) throws StripeException, IOException, MessagingException { 
         ...
 }
