Spring Boot REST多部分请求(file+json)引发415不受支持的媒体类型异常

Question

我使用的是Spring Boot版本=1.5.2.Release。当我在邮递员中发送带有json对象的多部分文件到上传文件时，它抛出了415不受支持的媒体类型异常。

这是我的控制器类。

@RestController
@RequestMapping("/service/promotion/")
public class JobController {
....
....
....
@RequestMapping(value = "/job/test", method = RequestMethod.POST, produces = "application/json", consumes = "multipart/form-data")
public ResponseEntity<Object> createJobTest(@Valid @RequestBody JobRequest jobRequest,
            @RequestParam(value = "file", required = false) MultipartFile multiPartFile) throws Exception {

我的json请求类。

 public class JobRequest {
        private String campaignKey;
        private String communicationId;
        private Integer channelId;
        private String templateType;
        private String subject;
        private String frequencyControl;
        private Integer leadsRequested;
        private String keywordRelavance;
        private String scheduledAt;
        private String file;
        private String updatedBy;
        
        //getter and setter
    }   

但是当我从controller类和postman中删除consumes时

@RequestMapping(value = "/job/test", method = RequestMethod.POST, produces = "application/json")

然后在controller类中出现调试器，但请求对象中的多部分文件值为空，如

谢谢你。

Answer 1

检查Jersey restful web service中与其他对象一起上载的文件

另一种方法是在文本中传递整个对象，就像在表单数据中传递文件和在对象中传递convert一样。

 @RequestMapping(value = "/uploadDocs", method = RequestMethod.POST, produces = "application/json", consumes = "multipart/form-data")
    public ResponseEntity<Object> methodName(@RequestParam("files") MultipartFile file, @RequestParam("anyKeyName") String objectString)

可以将字符串转换为对象

Class object = new ObjectMapper().readValue(objectString, Class.class);
