Rest API java spring-将文本和pdf上传到PostgreSQL数据库（邮递员-表单数据）

Question

我尝试了什么：将其添加到@PostMapping()-->没有成功

consumes = MediaType.MULTIPART_FORM_DATA_VALUE

在Postman中：添加了content-type:application/json和content-type:multipart/form-data

他们两个都没有成功：（...

@RestController
public class SheetMusicController {

    @Autowired
    SheetMusicRepository sheetMusicRepository;

    @GetMapping("/sheetmusic")
    public List<SheetMusic> index(){
        return sheetMusicRepository.findAll();
    }

    @PostMapping(value = "/sheetmusic")
    public SheetMusic create(@RequestBody Map<String,String> body){
        String title = body.get("title");
        byte[] pdf = "".getBytes();

        SheetMusic sheetMusic = new SheetMusic(title,"","","",pdf);
        return sheetMusic;
    }
}

问候，

您应该实现一个多部分form-data请求：

首先，您需要向Maven添加：

<dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId>commons-fileupload</artifactId>
    <version>1.3.1</version>
</dependency>

其次，您需要添加以下bean配置：

@Bean(name = "multipartResolver")
public CommonsMultipartResolver multipartResolver() {
    CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
    multipartResolver.setMaxUploadSize(100000);
    return multipartResolver;
}

@PostMapping(value = "/sheetmusic")
public SheetMusic create(@RequestParam("file") MultipartFile file, @RequestParam("title") String title) {
    // Your business
}
