如何在Spring security acl中爲某些Sid刪除AccessControlEntry（acl_entry）？

Question

我怎樣才能刪除用戶訪問在春季安全acl使用mutableAclService。 是這個代碼是確定

private void deleteEntry(Long id){ 

     ObjectIdentity objectIdentity = new ObjectIdentityImpl(OrganizationStructure.class, id); 

     Sid user = new PrincipalSid("admin"); 
     Permission p1 = BasePermission.READ; 

     try { 
      MutableAcl acl = (MutableAcl) mutableAclService.readAclById(objectIdentity); 
      acl.getEntries().forEach(c->{ 
       System.out.println(c.toString()); 
       if(c.getSid().equals(user)) 
        acl.getEntries().remove(c); 
      }); 
      mutableAclService.updateAcl(acl); 

     } catch (NotFoundException nfe) { 
     } 

    }

嘗試後，我發現自己如何刪除條目

private void deleteEntry(Long id) { 
     ObjectIdentity objectIdentity = new ObjectIdentityImpl(OrganizationStructure.class, id); 
     Sid user = new PrincipalSid(SecurityUtility.getAuthenticatedUser().getUsername()); 
     try { 
      MutableAcl acl = (MutableAcl) mutableAclService.readAclById(objectIdentity); 
      Consumer<AccessControlEntry> style = (AccessControlEntry p) -> System.out.println("id:"+p.getSid()); 
      acl.getEntries().forEach(style); 

      for (int i = 0; i < acl.getEntries().size(); i++) { 
       if (acl.getEntries().get(i).getSid().toString().equals(user.toString())) { 
        acl.deleteAce(i); 
        break; 
       } 
      } 

      acl.getEntries().forEach(style); 
      mutableAclService.updateAcl(acl); 
     } catch (NotFoundException nfe) { 
     } 

    }
