【中文标题】Postman：解析多部分 servlet 请求失败；嵌套异常是 java.lang.IllegalStateException, MultipartFile, REST【英文标题】：Postman: Failed to parse multipart servlet request; nested exception is java.lang.IllegalStateException, MultipartFile, REST 【发布时间】：2020-03-14 06:47:44 【问题描述】：我需要通过 Postman 将 image with JSON string 发送到我的 Rest API。我正在使用弹簧启动框架。请看下面的屏幕截图：
还请从应用程序终端查看完整的错误根目录：

我附在我的控制器类下面：
package MongoSpringREST.controllers;
import MongoSpringREST.models.Movie;
import MongoSpringREST.services.MovieServices;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import java.util.List;
@RestController
@RequestMapping("/Movies")
public class MovieController
@Autowired
private MovieServices movieServices;
@RequestMapping(value="/singleSave", method=RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public MultipartFile singleSave(@RequestParam(required = true, value = "file") MultipartFile file, @RequestParam(required = true, value = "text") String movie) throws Exception
System.out.println("File Description:" + movie);
return file;
Bean 配置类：
package MongoSpringREST.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;
import org.springframework.web.multipart.support.MultipartFilter;
@Configuration
public class MyConfig
@Bean
public CommonsMultipartResolver multipartResolver()
CommonsMultipartResolver multipart = new CommonsMultipartResolver();
multipart.setMaxUploadSize(3 * 1024 * 1024); return multipart;
@Bean
@Order(0)
public MultipartFilter multipartFilter()
MultipartFilter multipartFilter = new MultipartFilter();
multipartFilter.setMultipartResolverBeanName("multipartResolver");
return multipartFilter;

编辑：添加 application.properties：
#max file and request size
spring.http.multipart.max-file-size=10MB
spring.http.multipart.max-request-size=11MB
spring.http.multipart.enabled=true
有人知道问题出在哪里吗？
【问题讨论】：
你在使用zuul吗？可能也和ribbon + zuul有关。 另外，你能显示 POST 吗？也许你可以用 curl 命令伪造它？这通常是“为什么 Spring-boot 不调用我的 requestMapping”的来源。 我没有使用zuul。显示 POST 是什么意思？ POST请求是使用API。该错误看起来与多部分配置有关 - 这将在您的 application.properties 中。在此处检查您的属性：docs.spring.io/spring-boot/docs/2.0.0.M6/reference/htmlsingle/… 特别是 spring.servlet.multipart.enabled=true 属性 请参阅编辑部分的 application.properties。将其更改为“ spring.servlet.multipart.enabled=true”？ 【参考方案1】：根据https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-multipart-file-upload-configuration
建议使用容器的内置支持 分段上传，而不是引入额外的依赖 例如 Apache Commons 文件上传。
当您创建 CommonsMultipartResolver 类型的 multipartResolver bean 时，MultipartAutoConfiguration 不会自动配置 MultipartConfigElement bean。
我觉得
要么你应该使用 Spring Boot 自动配置来创建 multipartConfigElement:javax.servlet.MultipartConfigElement multipartResolver:org.springframework.web.multipart.support.StandardServletMultipartResolver beans 或一起创建您自己的CommonsMultipartResolver + MultipartConfigElement bean。
【讨论】：
【参考方案2】：While Sending Request in Postman
Header:
Content-Type multipart/form-data
Body:(form-data)
key file: image (browse image which u want to upload)
Key text:String that u want to sent.
【讨论】：
虽然这段代码 sn-p 可以解决问题，including an explanation 确实有助于提高您的帖子质量。请记住，您是在为将来的读者回答问题，而这些人可能不知道您提出代码建议的原因。以上是关于Postman：解析多部分 servlet 请求失败；嵌套异常是 java.lang.IllegalStateException, MultipartFile, REST的主要内容，如果未能解决你的问题，请参考以下文章
当前请求不是多部分请求 Spring Boot 和 Postman（上传 json 文件加上额外字段）
