/ 12 марта 2019

Я хочу использовать формат select2 ajax.

вот мой код.

DAO 

public interface SearchUserDAO {
    public List<Map<String, Object>> nationalityList();

Mapper 

<select id="nationalityList" resultType="map">
    SELECT nationality_num, nationality_en_name
      FROM nationality_dtb
</select>

Услуги 

public class SearchService {

@Autowired
private SearchUserDAO dao;

public List<Map<String, Object>> getInterestList(){
    return dao.interestList();
}

Контроллер 

@Controller
@RequestMapping("/search")
public class SearchController {

    @Autowired
    private SearchService service;

    @RequestMapping("/home")
    public String search(Model model, @RequestParam(value= "page", defaultValue = "1") int page) {

        Map<String, Object> params = new HashMap<String, Object>();
        params.put("page", page); // not for select2

        model.addAllAttributes(service.getViewData(params));

        Gson gson = new Gson();
        String nationality = gson.toJson(service.getNationalityList());
        model.addAttribute("nationality", nationality); // my data

        return "search/main";
    }

}

1017 * JSP * 

<div class="form-group">
    <label class="col-sm-3 control-label" for="id_city">거주 도시</label>
    <div class="col-sm-9">
<select class="form-control select-city" name="city">
<option></option>
</select>
<script>
$(document).ready(function(){
    $(".select-city").select2({
        allowClear: true,
        ajax:{
            url: "/search/home",
            dataType: 'json',
            delay: 250,
            data: {"id":"NATIONALITY_NUM", "text":"NATIONALITY_EN_NAME"}
        },
        placeholder: "선택"
    });
});
</script>

мои данные выглядят как 

[
{"NATIONALITY_EN_NAME":"Afghanistan","NATIONALITY_NUM":1},
{"NATIONALITY_EN_NAME":"Aland Islands","NATIONALITY_NUM":2},
{"NATIONALITY_EN_NAME":"Albania","NATIONALITY_NUM":3},
{"NATIONALITY_EN_NAME":"Algeria","NATIONALITY_NUM":4},
{"NATIONALITY_EN_NAME":"American Samoa","NATIONALITY_NUM":5},
{"NATIONALITY_EN_NAME":"Andorra","NATIONALITY_NUM":6},
{"NATIONALITY_EN_NAME":"Angola","NATIONALITY_NUM":7},
{"NATIONALITY_EN_NAME":"Anguilla","NATIONALITY_NUM":8},
{"NATIONALITY_EN_NAME":"Antarctica","NATIONALITY_NUM":9},
{"NATIONALITY_EN_NAME":"Antigua and Barbuda","NATIONALITY_NUM":10},
…
…
…
{"NATIONALITY_EN_NAME":"Uruguay","NATIONALITY_NUM":242},
{"NATIONALITY_EN_NAME":"Uzbekistan","NATIONALITY_NUM":243},
{"NATIONALITY_EN_NAME":"Vanuatu","NATIONALITY_NUM":244},
{"NATIONALITY_EN_NAME":"Vatican","NATIONALITY_NUM":245},
{"NATIONALITY_EN_NAME":"Venezuela","NATIONALITY_NUM":246},
{"NATIONALITY_EN_NAME":"Vietnam","NATIONALITY_NUM":247},
{"NATIONALITY_EN_NAME":"Wallis and Futuna","NATIONALITY_NUM":248},
{"NATIONALITY_EN_NAME":"Western Sahara","NATIONALITY_NUM":249},
{"NATIONALITY_EN_NAME":"Yemen","NATIONALITY_NUM":250},
{"NATIONALITY_EN_NAME":"Zambia","NATIONALITY_NUM":251},
{"NATIONALITY_EN_NAME":"Zimbabwe","NATIONALITY_NUM":252}
]
