Posting a file and JSON data to Spring rest service
I am building a Spring rest service for uploading a file. There is a form that consists of various field and one field for uploading a file. On submitting that form, I am sending a multipart form request ie Content-Type as multipart/form-data .
So I tried with below
@RequestMapping(value = "/companies", method = RequestMethod.POST)
public void createCompany(@RequestBody CompanyDTO companyDTO, @RequestParam(value = "image", required = false) MultipartFile image){
.................
But, the above didn't work. So for time being,i sent JSON data as String and forming Company Object from that String in rest service like
@RequestMapping(value = "/companies", method = RequestMethod.POST)
public void createCompany(@RequestParam("companyJson") String companyJson, @RequestParam(value = "image",required = false) MultipartFile image) throws JsonParseException, JsonMappingException, IOException{
CompanyDTO companyDTO = new ObjectMapper().readValue(companyJson, CompanyDTO.class);
.............................
Can't I send JSON data with @RequestBody without passing JSON as String?
Appending the values to the URL what u have been doing now using @RequestParam.
@RequestParam annotation will not work for complex JSON Objects , it is specifi for Integer or String .
If it is a Http POST method , use of @RequestBody will make the Spring to map the incoming request to the POJO what u have created (condition: if the POJO maps the incoming JSON)
create FormData() and append your json and file
if (form.validate()) {
var file = $scope.file;
var fd = new FormData();
fd.append('jsondata', $scope.jsonData);
fd.append('file', file);
MyService.submitFormWithFile('doc/store.html', fd, '', (response){
console.log(response)
});
}
//Service called in above
MyService.submitFormWithFile = function(url, data, config, callback) {
$http({
method : 'POST',
url : url,
headers : {
'Content-Type' : undefined
},
data : data,
transformRequest : function(data, headersGetterFunction) {
return data;
}
}).success(function(response, status, header, config) {
if (status === 200) {
callback(response);
} else {
console.log("error")
}
}).error(function(response, status, header, config) {
console.log(response);
});
};
// in your java part using ObjectMapper
//it is like string
fd.append('jsondata', JSON.stringify($scope.jsonData));
@Autowired
private ObjectMapper mapper;
@RequestMapping(value = "/companies", method = RequestMethod.POST)
public void createCompany(@RequestParam String jsondata,
@RequestParam(required = true) MultipartFile file){
CompanyDto companyDto=mapper.readValue(jsondata, CompanyDTO.class);
......
}
