歡迎star(收藏)
zTree 是一個依靠 jQuery 實現(xiàn)的多功能 “樹插件”。優(yōu)異的性能寿桨、靈活的配置、多種功能的組合是 zTree 最大優(yōu)點。

實現(xiàn)JpaRepository接口
package org.muses.jeeplatform.core.dao.repository.admin;
import org.muses.jeeplatform.core.entity.admin.Role;
import org.springframework.data.jpa.repository.JpaRepository;
/**

*/
public interface RoleRepository extends JpaRepository<Role,Integer> {
}
實現(xiàn)JpaRepository接口
package org.muses.jeeplatform.core.dao.repository.admin;
import org.muses.jeeplatform.core.entity.admin.Menu;
import org.springframework.data.jpa.repository.JpaRepository;
/**

public interface MenuTreeRepository extends JpaRepository<Menu,Integer>{

角色Service類：
package org.muses.jeeplatform.service;
import com.google.common.collect.Lists;
import org.muses.jeeplatform.core.dao.repository.admin.RolePageRepository;
import org.muses.jeeplatform.core.entity.admin.Role;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Sort;
import org.springframework.stereotype.Service;
import java.util.List;
/**
* Created by Nicky on 2017/7/30.
*/
@Service
public class RolePageService {
@Autowired
RolePageRepository roleRepository;
/**
* 構(gòu)建PageRequest對象
* @param num
* @param size
* @param asc
* @param string

private PageRequest buildPageRequest(int num, int size, Sort.Direction asc,
String string) {
return new PageRequest(num-1, size,null,string);
}
/**

*/
public Page<Role> findAll(int pageNo, int pageSize, Sort.Direction dir, String str){
PageRequest pageRequest = buildPageRequest(pageNo, pageSize, dir, str);
Page<Role> roles = roleRepository.findAll(pageRequest);
return roles;
}
public List<Role> findAllRole(){
Iterable<Role> roles = roleRepository.findAll();
List<Role> myList = Lists.newArrayList(roles);
return myList;
}
/**
* 根據(jù)角色id查找角色信息
* @param roleId
* @return
*/
public Role findByRoleId(String roleId){
return roleRepository.findOne(Integer.parseInt(roleId));
}
/**
* 保存角色信息
* @param role
*/
public void doSave(Role role){
roleRepository.save(role);
}
}
菜單Service類：
package org.muses.jeeplatform.service;
import org.muses.jeeplatform.annotation.RedisCache;
import org.muses.jeeplatform.common.RedisCacheNamespace;
import org.muses.jeeplatform.core.dao.repository.admin.MenuTreeRepository;
import org.muses.jeeplatform.core.entity.admin.Menu;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
/**
* Created by Nicky on 2017/6/17.
*/
@Service
public class MenuTreeService {
@Autowired
MenuTreeRepository menuTreeRepository;
/**
* 查詢所有的菜單
* @return
*/
@Transactional
//@RedisCache
public List<Menu> findAll(){
return menuTreeRepository.findAll();
}
}
在Controller類里通過角色id獲取該角色可以查看的菜單：
/**
* 跳轉(zhuǎn)到角色授權(quán)頁面
* @param roleId
* @param model
* @return
*/
@RequestMapping(value = "/goAuthorise" )
public String goAuth(@RequestParam String roleId, Model model){
List<Menu> menuList = menuTreeService.findAll();
Role role = roleService.findByRoleId(roleId);
Set<Permission> hasPermissions = null;
if(role != null){
hasPermissions = role.getPermissions();
}
for (Menu m : menuList) {
for(Permission p : hasPermissions){
if(p.getMenu().getMenuId()==m.getMenuId()){
m.setHasSubMenu(true);
}
}
}
model.addAttribute("roleId" , roleId);
JSONArray jsonArray = JSONArray.fromObject(menuList);
String json = jsonArray.toString();
json = json.replaceAll("menuId","id").replaceAll("parentId","pId").
replaceAll("menuName","name").replaceAll("hasSubMenu","checked");
model.addAttribute("menus",json);
return "admin/role/role_auth";
}
在前端通過zTree實現(xiàn)樹形菜單展示，通過勾選然后實現(xiàn)角色授權(quán)：
