java - SpringBoot REST Controller 抛出“不能有实体参数错误”

Question

我有以下 Spring Boot 控制器：

import java.io.InputStream;

import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import com.att.aft.dme2.internal.javaxwsrs.PUT;
import com.att.bttw.model.HelloWorld;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiResponse;
import io.swagger.annotations.ApiResponses;

@Api
@Path("/service")
@Produces({ MediaType.APPLICATION_JSON })
public interface RestService {


    @PUT
    @Path("/datarouter/{filename}")
    @Consumes("application/gzip")
    @Produces(MediaType.APPLICATION_JSON)
    Response testEndpoint(@Context HttpServletRequest request, @PathParam("filename") String filename, InputStream inputStream);

}

这个方法的实现很简单：

import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.core.Response;
import org.springframework.stereotype.Component;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.client.RestTemplate;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.beans.factory.annotation.Value;

import com.att.bttw.model.ApplicationResults;
import com.att.bttw.model.CountsDataModel;
import com.att.bttw.model.CountsDataResults;
import com.att.bttw.model.DisplayFieldRecord;
import com.att.bttw.model.DisplayRecord;
import com.att.bttw.model.WatermarkEventObject;
import com.fasterxml.jackson.databind.ObjectMapper;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.io.IOException;
import java.io.InputStream;
import java.sql.Timestamp;
import java.time.Instant;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;

@Override
    public Response testEndpoint(HttpServletRequest request, String filename, InputStream inputStream) {
        System.out.println("File name consumed: " + filename);
        return null;
    }

当我尝试点击此端点时，我收到以下错误：

"Following issues have been detected: Response testEndpoint(javax.servlet.http.HttpServletRequest, java.lang.String, java.io.InputStream), can not have an entity parameter. Try to move the parameter to the corresponding resource method".

当我删除 InputStream 和 HttpServletRequest 参数时，端点工作得很好，我只是不理解我收到的错误消息。
