基于ssm开发，maven项目引用阿里云镜像资源库，《商洛学院社团管理系统的设计与实现》
1.获取动态菜单列表
package com.sl.cms.service.admin.impl;
import java.util.ArrayList; import java.util.List; import java.util.Map; import java.util.stream.Collectors;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.sl.cms.dao.admin.HomeDao; import com.sl.cms.dto.MenuDto; import com.sl.cms.module.Module; import com.sl.cms.service.admin.HomeService;
@Service public class HomeServiceImpl implements HomeService { @Resource private HomeDao homeDao;//注入
@Override public List<MenuDto> getAllMenus() { List<Module> modules = homeDao.findAllModules(); List<MenuDto> mainList = new ArrayList<MenuDto>(); MenuDto currMenu = null; for(Module module:modules) { if(module.getM_pid()==null) {//是主菜单 currMenu = new MenuDto(); currMenu.setMenuId(module.getM_id()); currMenu.setMenuName(module.getM_name()); currMenu.setSubMenuList(new ArrayList<MenuDto>()); mainList.add(currMenu); }else {//子菜单 MenuDto subMenu = new MenuDto(); subMenu.setMenuId(module.getM_id()); subMenu.setMenuName(module.getM_name()); subMenu.setMenuUrl(module.getM_url()); currMenu.getSubMenuList().add(subMenu); } } return mainList; }
@Override public List<MenuDto> findDynamicModules(String u_id) { List<Module> modules = homeDao.findDynamicModules(u_id); System.out.println(modules); List<MenuDto> mainList=new ArrayList<MenuDto>(); MenuDto mainMenu=null; for(Module module:modules) { if(mainMenu==null || !mainMenu.getMenuId().equals(module.getP_id())) { mainMenu=new MenuDto(); mainMenu.setMenuId(module.getP_id()); mainMenu.setMenuName(module.getP_name()); mainMenu.setSubMenuList(new ArrayList<MenuDto>()); mainList.add(mainMenu); } MenuDto subMenu=new MenuDto(); subMenu.setMenuId(module.getM_id()); subMenu.setMenuName(module.getM_name()); subMenu.setMenuUrl(module.getM_url()); mainMenu.getSubMenuList().add(subMenu); } System.out.println("mainList:"+mainList); return mainList; }
@Override public List<MenuDto> findModulesOfUser(String userId) { List<Module> modules = homeDao.findModulesOfUser(userId); List<MenuDto> mainList = new ArrayList<MenuDto>(); MenuDto currMenu = null; for(Module module:modules) { if(module.getM_pid()==null) {//是主菜单 currMenu = new MenuDto(); currMenu.setMenuId(module.getM_id()); currMenu.setMenuName(module.getM_name()); currMenu.setSubMenuList(new ArrayList<MenuDto>()); mainList.add(currMenu); }else {//子菜单 MenuDto subMenu = new MenuDto(); subMenu.setMenuId(module.getM_id()); subMenu.setMenuName(module.getM_name()); subMenu.setMenuUrl(module.getM_url()); currMenu.getSubMenuList().add(subMenu); } } return mainList; }
@Override public List<MenuDto> findModulesOfRole(String roleId) { List<Module> moduleList = homeDao.findModulesOfRole(roleId); //Map<Object, List<Module>> pid=moduleList.stream().collect(Collectors.groupingBy(pid->pid.get("m_pid"))); return null; }
} 2.mvc-servlet.xml配置
