ztree所需實體類

package com.shp.dev.common;
public class Ztree {
 private String id;
 private String pId;
 private String name;
 public String getId() {
 return id;
 }
 public void setId(String id) {
 this.id = id;
 }
 public String getpId() {
 return pId;
 }
 public void setpId(String pId) {
 this.pId = pId;
 }
 public String getName() {
 return name;
 }
 public void setName(String name) {
 this.name = name;
 }
 public Ztree() {
 }
 public Ztree(String id,String pId,String name) {
 this.id = id;
 this.pId = pId;
 this.name = name;
 }
 @Override
 public String toString() {
 return "Ztree{" +
  "id='" + id + '\'' +
  ",pId='" + pId + '\'' +
  ",name='" + name + '\'' +
  '}';
 }
}

dao介面

package com.shp.dev.menu.dao;
import com.shp.dev.menu.pojo.Menu;
import java.util.List;
public interface MenuDao {
 List<Menu> queryAll();
}

dao的實現類

package com.shp.dev.menu.dao;
import com.shp.dev.menu.pojo.Menu;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository("menuDao")
public class MenuDaoImpl implements MenuDao{
 @Autowired
 private SessionFactory sessionFactory;
 @Override
 public List<Menu> queryAll() {
 return sessionFactory.getCurrentSession().createQuery("from Menu").list();
 }
}

業務介面

package com.shp.dev.menu.service;
import com.shp.dev.menu.pojo.Menu;
import java.util.List;
public interface MenuService {
 List<Menu> queryAll();
}

業務實現層

package com.shp.dev.menu.service;
import com.shp.dev.menu.dao.MenuDao;
import com.shp.dev.menu.pojo.Menu;
import com.shp.dev.role.dao.RoleDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
@Service("menuService")
public class MenuServiceImpl implements MenuService{
 //@Transactional(readOnly = true)//只讀事務
 // @Transactional(rollbackFor = Exception.class)//啟動事務，所有異常都回滾
 @Autowired
 private MenuDao menuDao;
 @Override
 @Transactional(readOnly = true)//只讀事務
 public List<Menu> queryAll() {
 return menuDao.queryAll();
 }
}

控制層

package com.shp.dev.menu.web;
import com.shp.dev.common.Ztree;
import com.shp.dev.menu.pojo.Menu;
import com.shp.dev.menu.service.MenuService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.ArrayList;
import java.util.List;
@Controller
@RequestMapping("/menu")
public class MenuController {
 @Autowired
 private MenuService menuService;
 @RequestMapping("/findZtree")
 @ResponseBody // 返回json物件
 public List<Ztree> findZtree(){
 List<Ztree> menus=new ArrayList<Ztree>();
 List<Menu> query = menuService.queryAll();
 for (Menu m : query) {
  menus.add(new Ztree(m.getId(),m.getParent_id(),m.getName()));
 }
 return menus;
 }
}
