使用Apache HTTP客户端和Spring REST发送HTTP PUT请求时出现问题

问题描述

我已经开发了一个简单的REST API，该API使用Spring Boot 2.3.1.RELEASE和Oracle JDK 14提供了一个简单的HTTP PUT请求。下面是服务器端REST端点：

@Controller
@RequestMapping("/api/documents")
public class DocumentController {

   @PutMapping(value = "/setCurrentTenant",consumes = "multipart/form-data")
    public ResponseEntity<?> setCurrentTenant(
             @RequestParam(value = "documentId",required = false) Long documentId,@RequestParam("tenantId") Long tenantId) {
        return documentService.setCurrentTenant(documentId,tenantId);
    }
}

以及客户端代码：

HttpPut putRequest = new HttpPut("http://localhost:8080/api/document/setCurrentTenant");
multipartentityBuilder entityBuilder = multipartentityBuilder.create();
    
builder.addTextBody("documentId","1");
builder.addTextBody("tenantId","10");
httpentity setCurrentTenantEntity = entityBuilder.build();
putRequest.setEntity(setCurrentTenantEntity);
httpClient = HttpClients.createDefault();
HttpResponse response = httpClient.execute(putRequest);

我试图运行代码，一切正常，但是当客户端请求发送到服务器时，Spring会记录如下异常：

Resolved [org.springframework.web.bind.MissingServletRequestParameterException:
 required Long parameter 'tenantId' is not present]

我想念什么吗？

解决方法

您应发送tenantId作为请求参数，例如

http：// localhost：8080 / api / document / setCurrentTenant？tenantId = 10

我担心为什么在不发送任何文件/二进制数据的情况下会消耗multipart / form-data

---

class TenantRequest {
  Long tenantId;
  Long documentId;
  //seter,getter
}

@PutMapping(value = "/setCurrentTenant",consumes = "multipart/form-data")
public ResponseEntity<?> setCurrentTenant(TenantRequest request) {
 // TODO
}

或

@PutMapping(value = "/setCurrentTenant",consumes = "multipart/form-data")
public ResponseEntity<?> setCurrentTenant(@ModelAttribute TenantRequest request) {
 // TODO
}
