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();
@Override
public 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, deleted
from 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；

}
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();
@Override
public 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,pid
from 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ID
String 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;
}
