選擇框使用jstl彈簧4 MVC，mongodb

-1

我想使用jstl throgh模型視圖做一個選擇框，我是一個純粹的noob，有人我已經通過這個，並創建此任何人都可以幫助我獲得monngodb值在選擇框中選擇框使用jstl彈簧4 MVC，mongodb

這裏是我的代碼

控制器

@RequestMapping(value = "getSpeciality", method = RequestMethod.GET) 
    public ModelAndView getSpeciality(HttpServletRequest request) { 

     Map<String, Object> myModel = new HashMap<String, Object>(); 
     myModel.put("myVar", getSpeciality(UtilsManagementService.getSpeciality())); // here is showing error UtilsManagementService cannot be resolved 
     return new ModelAndView("view", myModel); 
    }

管理層

package com.geniedoc.management.service; 

import java.util.List; 

import com.geniedoc.exception.BussniessException; 
import com.geniedoc.exception.UserNotFoundException; 
import com.geniedoc.vo.CityVo; 
import com.geniedoc.vo.SpecialityVO; 


public interface UtilsManagementService { 


    public List<SpecialityVO> getSpeciality(String key) throws BussniessException; }

@Override 
public Speciality getSpeciality(String specialityName) { 
    Query findSpecialityQuery = new Query(); 
    findSpecialityQuery.addCriteria(Criteria.where(SPECIALITY_NAME).regex(specialityName)); 
    Speciality speciality = null; 
    try{ 
     speciality = this.specialityRepository.getDocument(Speciality.class, findSpecialityQuery, SPECIALITY_TABLE); 
    }catch(MongoDBDocumentNotFoundException e){ 
     e.printStackTrace(); 
    } 

    return speciality; 
}

和jsp

<select id="Speciality" name=""Speciality""> 
     <c:forEach var="item" items="${myModel}"> 
     <option value="${item.key}">${item.value}</option> 
     </c:forEach> 
    </select>

專業VO

package com.geniedoc.vo; 

public class SpecialityVO { 

    private int _id; 
    private String speciality_name; 
    private String speciality_description; 
    public String getSpeciality_name() { 
     return speciality_name; 
    } 
    public void setSpeciality_name(String speciality_name) { 
     this.speciality_name = speciality_name; 
    } 
    public String getSpeciality_description() { 
     return speciality_description; 
    } 
    public void setSpeciality_description(String speciality_description) { 
     this.speciality_description = speciality_description; 
    } 
    public int get_id() { 
     return _id; 
    } 
    public void set_id(int _id) { 
     this._id = _id; 
    } 




}

你能告訴我們你面對的確切問題 –

@RamanaManoj在非常fisrt的代碼它顯示錯誤我已經給了那條線，它在哪裏給出錯誤//我想從mongodb獲取值並填充選擇標籤 – user6409738

你需要注入UtilsManagementService（這將有一個試行）到控制器。定義bean並自動裝入它。

然後使用服務返回的模型。

我沒有發現您的jstl代碼有任何問題。
