Spring boot 增加上传到Jhipster网关中API的文件大小

我用Jhipster创建了用于管理文件（图像、视频）的微服务。当我直接调用它时，工作正常，我可以上载大文件（超过1MB，默认大小），但当它位于Jhipster网关后面时，返回此错误：

{
  "type": "https://www.jhipster.tech/problem/problem-with-message",
  "title": "Internal Server Error",
  "status": 500,
  "detail": "io.undertow.server.RequestTooBigException: UT000020: Connection terminated as request was larger than 10485760",
  "path": "/error",
  "message": "error.http.500"
}

在我的控制台日志中打印：

所以我用谷歌搜索它并找到一个解决方案，将这一行添加到应用程序属性文件：

spring.servlet.multipart.enabled: true
spring.servlet.multipart.max-file-size: 1024MB
spring.servlet.multipart.max-request-size: 1024MB

但现在gateway只需在我调用API的响应中返回以下内容：

{
  "timestamp": "2019-09-27T05:42:47.311+0000",
  "status": 403,
  "error": "Forbidden",
  "message": "Forbidden",
  "path": "/knowyourcustomer/api/kyc/media"
}

最后请注意，这是我的API方法签名：

@PostMapping(path = "/media", consumes = { "multipart/form-data" })
    public ResponseEntity<?> saveMedia(@RequestPart String idType,
                                       @RequestPart(required = false) String secret,
                                       @RequestPart MultipartFile file)
            throws URISyntaxException, IOException

@PostMapping（path=“/media”，使用={“多部分/表单数据”}）
公共响应属性存储媒体（@RequestPart String idType，
@RequestPart（必需=false）字符串机密，
@RequestPart（多部分文件）
抛出URISyntaxException，IOException

在springboot 2.0中+

spring:
  servlet:
    multipart:
      max-file-size: 104857600
      max-request-size: 104857600

---

您在“spring”下设置的属性是什么？与spring.servlet.multipart.max-file-size类似，请参见是的。我忘了在行的开头添加spring。您是否在网关或注册表中设置了属性（假设您将其用作服务发现）？关于403错误，您是否检查了服务器日志？它是由网关还是服务触发的？日志语句是什么？您是否通过了身份验证标头？此参数“secret”表示它是一个自定义实现，您是否与使用blob实体字段的标准JHipster实现进行了比较？我在服务和网关属性中设置了JHipster/Spring Boot的哪个版本；在添加到网关属性后，我得到了403；不清楚，因为控制台中没有日志；是的，我将令牌传递给我的API，并用另一个API测试它，一切正常；“秘密”传递给API，对Spring安全没有任何特殊意义，我必须将其存储在DB上；正如我所说，当我直接调用它，没有中间网关，一切都很好！这很奇怪，我知道…请考虑如何解释属性解决OP的问题。
