将JSON对象发送到Spring控制器

Question

Could someone please tell me why I am getting empty body in the controller. Here is my test

 public void updatePackage() throws Exception {

    JSONObject updateObj = new JSONObject();

    updateObj.append("packageType", "packageType-update-endpoint");


    SPackage updatedResponse = null;

    try {
        String json = updateObj.toString();
        System.out.println("**** JSON **** ");
        System.out.println(json + "----------" + this.response.getId());
        ResultActions result = mvcController.perform(put("/package/" + this.response.getId())
                .content(json)
                .contentType(MediaType.APPLICATION_JSON))
                .andDo(print())
                .andExpect(status().isOk());
        updatedResponse = JsonUtil.<SPackage>convertJsonToObject(
                result.andReturn().getResponse().getContentAsString(), SPackage.class);
    } catch (Exception e) {
        e.printStackTrace();
        fail("Unexpected exception" + e);
    }

}

and here my controller method

@RequestMapping(value = "/package/{id}", method = RequestMethod.PUT)
@ResponseStatus(HttpStatus.OK)
@ResponseBody
public SPackage updatePackage(@PathVariable String id, @RequestBody JSONObject sPackage) {
    if (sPackage == null) {
        throw new BadRequestException("Given package is null");
    }

    return softwarePackageService.updatePackage(id,sPackage);
}

I am using Spring MVC Controller Mock

Answer 1

Just try to Give datatype only String and try to convert it to the Json format at the Server side. and hope that will work.

So simple solution is Send String and convert into the JSON

Answer 2

I have modified the code as follows.

           ResultActions result = mvcController.perform(put("/package/" + this.response.getId())
            .content(new ObjectMapper().writeValueAsString(updateObj.toString()))
            .contentType(MediaType.APPLICATION_JSON))
            .andDo(print())
            .andExpect(status().isOk());

I need to do a .toString() to json object and then pass to the ObjectMapper.writeValueAsString method
