3.权限管理器

3.1 权限列表展示功能

1）原型效果

2）接口说明

功能描述： 查询所有权限集合
服务路径： /api/permissions
服务方法：Get
请求参数：无

响应数据格式:

{"code": 1,"data": [{"id": 1236916745927790556,"code": "btn-user-delete","title": "删除用户权限","icon": "","perms": "sys:user:delete","url": "/api/user","method": "DELETE","name": "","pid": 1236916745927790575,"orderNum": 100,"type": 3,"status": 1,"createTime": "2020-01-08T07:42:50.000+00:00","updateTime": null,"deleted": 1},{"id": 1473855535827783680,"code": "","title": "测试-01","icon": "el-icon-user-solid","perms": "","url": null,"method": "","name": "test-01","pid": 0,"orderNum": 555,"type": 1,"status": 1,"createTime": "2021-12-23T03:18:36.000+00:00","updateTime": "2021-12-23T03:18:36.000+00:00","deleted": 1}//...............]
}

代码实现

1. 表现层

    @ApiOperation(value = "权限列表展示功能")@GetMapping("/permissions")public R<ArrayList<SysPermission>> getPermissions(){return service.getPermissions();}

2. 服务层

R<ArrayList<SysPermission>> getPermissions();

    @Overridepublic R<ArrayList<SysPermission>> getPermissions() {ArrayList<SysPermission> permisson_data = sysPermissionMapper.getPermissions();return R.ok(permisson_data);}

3. Dao层

ArrayList permisson_data = sysPermissionMapper.getPermissions();

ArrayList<SysPermission> getPermissions();

    <select id="getPermissions" resultType="com.jixu.stock.pojo.entity.SysPermission">select id, code, title, icon, perms, url, method, name, pid, order_num, type, status, create_time, update_time, deletedfrom sys_permission;</select>

3.3 添加权限时回显权限树

1）原型效果

2）接口说明

功能描述： 添加权限时回显权限树,仅仅显示目录和菜单
服务路径： /api/permissions/tree
服务方法：Get
请求参数：无

响应数据格式:

保证数据顺序；

{"code": 1,"data": [{"id": "0","title": "顶级菜单","level": 0},{"id": "1236916745927790564","title": "组织管理","level": 1},{"id": "1236916745927790560","title": "菜单权限管理","level": 2},{"id": "1236916745927790575","title": "用户管理","level": 2},{"id": "1236916745927790578","title": "角色管理","level": 2},{"id": "1236916745927790569","title": "系统管理","level": 1},{"id": "1236916745927790558","title": "接口管理","level": 2},{"id": "1236916745927790571","title": "SQL监控","level": 2},{"id": "1236916745927790589","title": "日志管理","level": 2},{"id": "1247842736313339904","title": "测试菜单","level": 1},{"id": "1247871697634332672","title": "测试子菜单","level": 2},{"id": "1247877926632951808","title": "测试子菜单1","level": 2},{"id": "1247880664557162496","title": "测试菜单2","level": 1},{"id": "1247881176622960640","title": "测试子菜单2","level": 2},{"id": "1247881904334704640","title": "测试子菜单3","level": 2},{"id": "1469201551976435712","title": "任务管理","level": 1},{"id": "1473855535827783680","title": "测试-01","level": 1}]
}

代码实现

1. 表现层

    @ApiOperation(value = "添加权限时回显权限树")@GetMapping("/permissions/tree")public R<ArrayList<HashMap>> getPermissionsTree(){return service.getPermissionsTree();}

2. 服务层

R<ArrayList<HashMap>> getPermissionsTree();

    @Overridepublic R<ArrayList<HashMap>> getPermissionsTree() {// 获取全部数据ArrayList<PermissonTreeDomian> permisson_data = sysPermissionMapper.getPermissionTree();// 组装数据进行递归HashMap<Long, PermissonTreeDomian> data = new HashMap<>();for (PermissonTreeDomian permissonDatum : permisson_data) {Long id = permissonDatum.getId();HashMap<Long, PermissonTreeDomian> map = new HashMap<>();map.put(id , permissonDatum);data.put(id ,permissonDatum);}// 进行递归ArrayList<HashMap> treeList = new ArrayList<>();HashMap<String, Object> map = new HashMap<>();map.put("id",0);map.put("title","顶级菜单");map.put("level",0);treeList.add(map);TreeUtil.buildPermissionTree(data, Long.valueOf(0),1,treeList);return R.ok(treeList);}

3. Dao层

// 获取全部数据
ArrayList permisson_data = sysPermissionMapper.getPermissionTree();

ArrayList<PermissonTreeDomian> getPermissionTree();

    <select id="getPermissionTree" resultType="com.jixu.stock.pojo.domain.PermissonTreeDomian">select id,title,pidfrom sys_permission;</select>

4. 工具类

public static List<HashMap> buildPermissionTree(Map<Long, PermissonTreeDomian> permissionMap, Long parentId , Integer count,List<HashMap> treeList) {// 创建列表用于保存数据// 循环查询是否有符合条件的数据for (Map.Entry<Long, PermissonTreeDomian> entry : permissionMap.entrySet()) {PermissonTreeDomian permissionDomain = entry.getValue();// 如何Id== pid 则获取到了if (parentId.equals(permissionDomain.getPid())) { // 假设PermissonTreeDomian类中有一个getPid()方法返回父IDString title = permissionDomain.getTitle();Long id = permissionDomain.getId();HashMap<String, Object> map = new HashMap<>();map.put("id" , id);map.put("title" , title);map.put("count" , count);treeList.add(map);buildPermissionTree(permissionMap, permissionDomain.getId(),count+1,treeList);}}return treeList;}

5. 实体类

@Data
public class PermissonTreeDomian {private Long id;private Long pid;private String title;
}
