如何从Java后端下载数据？

Question

我从服务器请求json或xml数据。

我控制台日志，对于JSON，我看到json数据，对于XML，我看到#Document

如何将这些数据分别下载到json文件和xml文件中？

Java

@RestController
    public class RestCtrl {

    @Autowired
    JdbcTemplate jdbcTemplate;

    @RequestMapping(value="getJSON", method = RequestMethod.GET , produces = {MediaType.APPLICATION_JSON_VALUE})
    List<Map<String, Object>> getJSONData(@RequestParam String query) {
        List<Map<String, Object>> data = jdbcTemplate.queryForList("SELECT * FROM TICKETS");
        return data;
    }

    @RequestMapping(value="getXML", method = RequestMethod.GET , produces = {MediaType.APPLICATION_XML_VALUE})
    List<Map<String, Object>> getXMLData(@RequestParam String query) {
        List<Map<String, Object>> data = jdbcTemplate.queryForList("SELECT * FROM TICKETS");
        return data;
    }
}

jQuery

  $('#download').click(function () {
   var query = $('#query').val();
   var type = $('#type').val();

   console.log('/get' + type);
   $.ajax({
       type: 'get',
       url: '/get' + type,
       data: {query: query},
       success: function (result) {
          console.log(result);
          //download the file
       },
       error: function () {
           $('#message').html('Error downloading the file')
       }

   })
});
