Question

Please see below code where i want to send request having file and other json data which will be in a single java class:
My Class is(used lombok):
#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 })

CustomFileUploadSearch cfuSearch = entity.getBody();
}
I am not able to reach into this method.
Please help me so that it has already taken 1 day.
Thanks in advance.
#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());
}

Answer 2

You can explicitly get MultipartFile as request input parameter in RestController.
#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);
}
}
