篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了JavaEE权限管理系统的搭建--------角色的增删改相关的知识，希望对你有一定的参考价值。
如下图所示，添加角色的同时，要给角色分配权限菜单，关于权限数的显示，我实现了两种方式，普通方式和Ztree方式，
普通方式展示树：
主要代码部分：
/** * 进入角色添加页面 * @param model * @return */ @AccessPermissionsInfo("role:add") @RequestMapping(value = "/role-add.action",method = RequestMethod.GET) public String roleAddPage(Model model){ Role role = new Role(); model.addAttribute("role",role); //获取所有权限集合 List<Permission> allPermissionsList = permissionService.findAllPermission(); //储存的是根节点集合 List<Permission> permissionsList = new ArrayList<Permission>(); //获取所有根节点 for(Permission p:allPermissionsList){ if(p.getParentId().toString().equals("0")|| Integer.parseInt(p.getParentId().toString())==0){ permissionsList.add(p); } } //遍历根节点集合，为根节点设置子节点 for(Permission p:permissionsList){ //findChild方法递归查找子节点 p.setChildPermissions(findChild(p.getId(),allPermissionsList)); } model.addAttribute("permissionsList",permissionsList); return "role-add"; } /** * 查找子节点 * @param id 父节点的ID * @param allPermissionsList 所有权限的集合 * @return */ private List<Permission> findChild(Integer id, List<Permission> allPermissionsList) { List<Permission> childPermissions = new ArrayList<Permission>(); //遍历所有权限列表 for(Permission p:allPermissionsList){ //如果子节点的parentId等于父节点的ID if(p.getParentId().equals(id)){ //添加到子节点 childPermissions.add(p); } } //再次循环子菜单 for(Permission p:childPermissions){ p.setChildPermissions(findChild(p.getId(),allPermissionsList)); } if(childPermissions.size()==0){ return null; } return childPermissions; } /** * 添加角色信息 * @param request * @return */ @AccessPermissionsInfo("role:add") @RequestMapping(value = "/role-add.action",method = RequestMethod.POST) @ResponseBody public Map<String,Object> roleAdd(HttpServletRequest request) { Map<String,Object> resultMap = new HashMap<String,Object>(); String[] ids = request.getParameterValues("pers"); if(request.getParameter("roleName")==null|| request.getParameter("roleRemark")==null) { resultMap.put("result","参数异常"); }else if(ids==null||ids.length<=0) { resultMap.put("result","请给角色至少分配一个权限"); }else { String roleName = request.getParameter("roleName").toString(); String roleRemark = request.getParameter("roleRemark").toString(); AdminUser adminUser = (AdminUser)request.getSession().getAttribute("adminUser"); if(adminUser!=null){ Role role = roleService.findRoleByRoleName(roleName); if(role==null){ Role role2 = new Role(); role2.setRoleName(roleName); role2.setRoleRemark(roleRemark); int count = roleService.addRole(role2,ids); if(count>0){ resultMap.put("result","SUCCESS"); }else { resultMap.put("result","操作失败"); } }else { resultMap.put("result","角色已存在"); } }else { resultMap.put("result","登录超时，请重新登录"); } } return resultMap; }
