Spring Boot 使用多个对象上传多个文件 [英] Spring Boot multiple files upload with multiple objects

问题描述

我需要帮助，我上次使用带有对象的单个文件上传创建控制器，它对我有用

我的 POJO 课

@JsonInclude(JsonInclude.Include.NON_NULL)@JsonPropertyOrder({ "文件", "数据" })公共类 FileWithObject{@JsonProperty("文件")私有 MultipartFile 文件；@JsonRawValue@JsonProperty("数据")私人 T 数据；}

<块引用>

我的休息控制器

@RequestMapping(value="/filestore/{bucket-uuid}/appsport.com/singleFileUploadWithObject/{folder}",方法 = RequestMethod.POST)@ResponseBody//api 工作公共字符串 singleFileUploadWithObject(@PathVariable(name="bucket-uuid", required = true) 字符串bucketUUId，@PathVariable(name="folder", required = false) 字符串文件夹，FileWithObject rawData) {返回ping响应；}

我的邮递员结果

这对我来说都是有用的.如何通过邮递员发送对象列表，或者可以像下面的rest控制器一样处理这种请求

@RequestMapping(value="/filestore/{bucket-uuid}/appsport.com/listOfObjectsWithSingleFile/{folder}", method = RequestMethod.POST)@ResponseBody公共字符串 listOfObjectsWithSingleFile(@PathVariable(name="bucket-uuid", required = true) 字符串bucketUUId，@PathVariable(name="folder", required = false) 字符串文件夹，设置原始数据) {返回ping响应；}

如何处理对象列表

<代码>[{文件":文件对象，数据":zyz"},{文件":文件对象，数据":zyz"}]

<块引用>

我正在尝试为此打击任务创建 api

解决方案

我通过使用元数据概念来做到这一点，我在控制器和bean

中所做的更改很少<块引用>

控制器

@RequestMapping(value="/filestore/{bucket-uuid}/appsport.com/listOfObjectsWithSingleFile/{folder}",方法 = RequestMethod.POST)@ResponseBody公共字符串 listOfObjectsWithSingleFile(@PathVariable(name="bucket-uuid") 字符串bucketUUId，@PathVariable(name="folder") 字符串文件夹，FileWithObject objects) {//改变这个 SetrawData 到 FileWithObject 对象返回ping响应；}

<块引用>

豆

@JsonInclude(JsonInclude.Include.NON_NULL)@JsonPropertyOrder({ "文件", "文件", "数据" })公共类 FileWithObject{@JsonProperty("文件")私有 MultipartFile 文件；@JsonProperty("文件")私有列表档案；@JsonRawValue@JsonProperty("数据")私人 T 数据；//像(元数据)一样工作列表原始数据;//获取设置器}

注意:- 我仍在寻找这个问题，以一种打击的方式处理这个问题

@RequestMapping(value="/filestore/{bucketuuid}/appsport.com/listOfObjectsWithSingleFile/{folder}", method = RequestMethod.POST)@ResponseBodypublic String listOfObjectsWithSingleFile(@PathVariable(name="bucket-uuid", required = true) String bucketUUId,@PathVariable(name="folder", required = false) String folder,Set原始数据) {返回ping响应；}

希望对大家有所帮助

I need help I last time create the controller with the single file upload with an object and it's work for me like

My POJO class

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({ "file", "data" })
public class FileWithObject<T> {

    @JsonProperty("file")
    private MultipartFile file;
    @JsonRawValue
    @JsonProperty("data")
    private T data;
}

MY REST CONTOLLER

@RequestMapping(value="/filestore/{bucket-uuid}/appsport.com/singleFileUploadWithObject/{folder}",
        method = RequestMethod.POST)
@ResponseBody
// api work
public String singleFileUploadWithObject(
        @PathVariable(name="bucket-uuid", required = true) String bucketUUId,
        @PathVariable(name="folder", required = false) String folder,
        FileWithObject rawData) {
    return pingResponse;
}

My Postman result

That's all work for me. How to send the list of the objects through the postman or is possible to handle that way request like below rest controller

@RequestMapping(value="/filestore/{bucket-uuid}/appsport.com/listOfObjectsWithSingleFile/{folder}", method = RequestMethod.POST)
@ResponseBody
public String listOfObjectsWithSingleFile(
        @PathVariable(name="bucket-uuid", required = true) String bucketUUId,
        @PathVariable(name="folder", required = false) String folder,
        Set<FileWithObject> rawData) {
    return pingResponse;
}

How to handle list of objects

[{
"file": fileobject,
"data": "zyz"
},{
"file": fileobject,
"data": "zyz"
}]

I'm trying to creating the api for this blow task

解决方案

I have done this by use of Meta-Data concept there are few changes I did in controller and bean

Controller

@RequestMapping(value="/filestore/{bucket-uuid}/appsport.com/listOfObjectsWithSingleFile/{folder}",
        method = RequestMethod.POST)
@ResponseBody
public String listOfObjectsWithSingleFile(
        @PathVariable(name="bucket-uuid") String bucketUUId, @PathVariable(name="folder") String folder,
        FileWithObject objects) { // change this Set<FileWithObject> rawData to FileWithObject objects
    return pingResponse;
}

Bean

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({ "file", "files", "data" })
public class FileWithObject<T> {

    @JsonProperty("file")
    private MultipartFile file;
    @JsonProperty("files")
    private List<MultipartFile> files;
    @JsonRawValue
    @JsonProperty("data")
    private T data;

    // work like (meta-data)
    List<FileWithObject> rawData;
    // getter setter
}

Image's For Request

Note:- I'm Still looking for this issue handle this in a blow way

@RequestMapping(value="/filestore/{bucketuuid}/appsport.com/listOfObjectsWithSingleFile/{folder}", method = RequestMethod.POST)
@ResponseBody
public String listOfObjectsWithSingleFile(@PathVariable(name="bucket-uuid", required = true) String bucketUUId,
    @PathVariable(name="folder", required = false) String folder,Set<FileWithObject> rawData) {
    return pingResponse;
}
