所以我找到了一种方法。您需要实现RequestStreamHandler，它为您提供可以使用的输入和输出流：
import com.amazonaws.services.lambda.runtime.RequestStreamHandlerpublic class ChartHandler implements RequestStreamHandler { private ObjectMapper objectMapper = new ObjectMapper(); @Override public void handleRequest(InputStream inputStream, OutputStream outputStream, Context context) throws IOException { DeserializationClass deserializedInput = objectMapper.readValue(inputStream, DeserializationClass.class) objectMapper.writevalue(outputStream, deserializedInput); //write to the outputStream what you want to return }}具有输入和输出流使您独立于用于解析它的格式和框架。
