Question

请参阅下面的代码，我要在其中发送具有文件和其他json数据的请求，这些请求将在单个java类中：

我的班级是（使用龙目岛）：

@Data
public class CustomFileUploadSearch {

    private Long selectedId;
    private MultipartFile file; 
}

@RequestMapping(method = RequestMethod.POST, path = "/rest/GIER/testFileData", 
    consumes = {"multipart/form-data"}, produces = { MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity bulkActivateInactivate(HttpEntity<CustomFileUploadSearch> entity, HttpServletRequest request) {

        CustomFileUploadSearch cfuSearch = entity.getBody();
}

我无法使用此方法。

请帮助我，因为它已经用了1天。

谢谢。

@RestController
public class ChassisInventoryRest {

    @SuppressWarnings("rawtypes")
    @RequestMapping(method = RequestMethod.POST, path = "/rest/GIER/testFileData", 
    consumes = {"multipart/form-data"}, produces = { MediaType.APPLICATION_JSON_VALUE })
    public ResponseEntity bulkActivateInactivate(HttpEntity<CustomFileUploadSearch> entity, HttpServletRequest request) {

        CustomFileUploadSearch cfuSearch = entity.getBody();
        System.out.println("cfuSearch.getSelectedId():"+cfuSearch.getSelectedId());
        System.out.println("cfuSearch.getFile():"+cfuSearch.getFile());

        return new ResponseEntity<Map<String, Object>>( new HashMap<String, Object>(), HttpStatus.OK);
    }
}

Answer 1

public class CustomFileUploadSearch {

   private Long selectedId;
    private MultipartFile file;

    public Long getSelectedId() {
        return selectedId;
    }
    public void setSelectedId(Long selectedId) {
        this.selectedId = selectedId;
    }
    public MultipartFile getFile() {
        return file;
    }
    public void setFile(MultipartFile file) {
        this.file = file;
    } 
}

@RequestMapping(method = RequestMethod.POST)
public ResponseEntity bulkActivateInactivate(CustomFileUploadSearch  entity, HttpServletRequest request) {

        System.out.println(entity.getSelectedId());
        System.out.println(entity.getFile());


}

您可以在RestController中显式获取MultipartFile作为请求输入参数。

@RestController
public class ChassisInventoryRest {
 @PostMapping(path = "/rest/GIER/testFileData", consumes = MediaType.MULTIPART_FORM_DATA_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
 public ResponseEntity bulkActivateInactivate(@RequestParam MultipartFile file, @RequestParam Long selectedId) {
    //parameterized constructor
    CustomFileUploadSearch cfuSearch = new CustomFileUploadSearch(selectedId, file);

    return new ResponseEntity<Map<String, Object>>( new HashMap<String, Object>(), HttpStatus.OK);
    }
}

如何使用@RestController和HttpEntity <class>作为输入参数，在Rest服务中映射请求包含文件和数据
