## Differenze nella creazione di una dichiarazione
<a name="migration-iam-policy-builder-statement"></a>

### Azioni
<a name="migration-iam-policy-builder-statement-actions"></a>

#### v1
<a name="migration-iam-policy-builder-statement-actions.v1"></a>

L'SDK v1 dispone [`enum`di tipi di](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/Action.html) azioni di servizio che rappresentano `[https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_action.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_action.html)` elementi di una dichiarazione politica. I seguenti `enum` tipi sono alcuni esempi.
+ `[IdentityManagementActions](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/actions/IdentityManagementActions.html)`
+ `[DynamoDBv2Actions](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/actions/DynamoDBv2Actions.html)`
+ `[SQSActions](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/actions/SQSActions.html)`

L'esempio seguente mostra la `SendMessage` costante for`SQSActions`.

```
Action action = SQSActions.SendMessage;
```

Non è possibile specificare un `[https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notaction.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notaction.html)` elemento in un'istruzione in v1.

####   v2
<a name="migration-iam-policy-builder-statement-actions.v2"></a>

Nella v2, l'[IamAction](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/policybuilder/iam/IamAction.html)interfaccia rappresenta tutte le azioni. Per specificare un elemento di [azione specifico del servizio](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_action.html), passate una stringa al `create` metodo come illustrato nel codice seguente.

```
IamAction action = IamAction.create("sqs:SendMessage");
```

È possibile specificare un'istruzione `[https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notaction.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notaction.html)` for a con v2, come illustrato nel codice seguente.

```
IamAction action = IamAction.create("sqs:SendMessage");
IamStatement.builder().addNotAction(action);
```

### Condizioni
<a name="migration-iam-policy-builder-statement-conditions"></a>

#### v1
<a name="migration-iam-policy-builder-statement-conditions-v1"></a>

Per rappresentare le condizioni delle dichiarazioni, l'SDK v1 utilizza sottoclassi di. [https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/Condition.html](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/Condition.html) 
+  [ArnCondition](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/conditions/ArnCondition.html) 
+  [BooleanCondition](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/conditions/BooleanCondition.html)
+  [DateCondition](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/conditions/DateCondition.html)
+ [IpAddressCondition](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/conditions/IpAddressCondition.html)
+ [NumericCondition](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/conditions/NumericCondition.html)
+ [ StringCondition ](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/conditions/StringCondition.html)

Ogni `Condition` sottoclasse definisce un `enum` tipo di confronto per aiutare a definire la condizione. Ad esempio, quanto segue mostra un [confronto di stringhe](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition_operators.html#Conditions_String) *non simile* per una condizione.

```
Condition condition = new StringCondition(StringComparisonType.StringNotLike, "key", "value");
```

####   v2
<a name="migration-iam-policy-builder-statement-conditions-v2"></a>

Nella v2, si crea una condizione per una dichiarazione politica utilizzando `[IamCondition](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/policybuilder/iam/IamCondition.html)` e fornendo un`[IamConditionOperator](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/policybuilder/iam/IamConditionOperator.html)`, che contiene `enums` per tutti i tipi.

```
IamCondition condition = IamCondition.create(IamConditionOperator.STRING_NOT_LIKE, "key", "value");
```

### Resources
<a name="migration-iam-policy-builder-statement-resources"></a>

#### v1
<a name="migration-iam-policy-builder-statement-resources-v1"></a>

L'`[https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_resource.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_resource.html)`elemento di una dichiarazione politica è rappresentato dalla classe dell'SDK. `[Resource](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/Resource.html)` L'ARN viene fornito come stringa nel costruttore. Le seguenti sottoclassi forniscono costruttori di convenienza.
+ [S3BucketResource](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/resources/S3BucketResource.html)
+ [S3ObjectResource](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/resources/S3ObjectResource.html)
+ [SQSQueueRisorsa](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/resources/SQSQueueResource.html)

Nella v1, è possibile specificare un `[https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notresource.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notresource.html)` elemento per a `[Resource](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/Resource.html)` chiamando il `withIsNotType` metodo come illustrato nella seguente istruzione.

```
Resource resource = new Resource("arn:aws:s3:::amzn-s3-demo-bucket").withIsNotType(true);
```

####   v2
<a name="migration-iam-policy-builder-statement-resources-v2"></a>

Nella v2, si crea un `[https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_resource.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_resource.html)` elemento passando un ARN al `IamResource.create` metodo.

```
IamResource resource = IamResource.create("arn:aws:s3:::amzn-s3-demo-bucket");
```

An `[IamResource](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/policybuilder/iam/IamResource.html)` può essere impostato come *[https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notresource.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notresource.html)*elemento come mostrato nel frammento seguente.

```
IamResource resource = IamResource.create("arn:aws:s3:::amzn-s3-demo-bucket");
IamStatement.builder().addNotResource(resource);
```

`IamResource.ALL`rappresenta tutte le risorse. 

### Principali
<a name="migration-iam-policy-builder-statement-principal"></a>

#### v1
<a name="migration-iam-policy-builder-statement-principal-v1"></a>

L'SDK v1 offre le seguenti `[Principal](https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/auth/policy/Principal.html)` classi per rappresentare i tipi di principali che includono tutti i membri:
+ `AllUsers`
+ `AllServices`
+ `AllWebProviders`
+ `All`

Non è possibile aggiungere un `[https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notprincipal.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notprincipal.html)` elemento a un'istruzione.

####   v2
<a name="migration-iam-policy-builder-statement-principal-v2"></a>

Nella v2, `IamPrincipal.ALL` rappresenta tutti i principali:

Per rappresentare tutti i membri in altri tipi di principali, usa `[IamPrincipalType](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/policybuilder/iam/IamPrincipalType.html)` le classi quando crei un. `IamPrincipal`
+ `IamPrincipal.create(IamPrincipalType.AWS,"*")`per tutti gli utenti.
+ `IamPrincipal.create(IamPrincipalType.SERVICE,"*")`per tutti i servizi.
+ `IamPrincipal.create(IamPrincipalType.FEDERATED,"*")`per tutti i provider web.
+ `IamPrincipal.create(IamPrincipalType.CANONICAL_USER,"*")`per tutti gli utenti canonici.

È possibile utilizzare il `addNotPrincipal` metodo per rappresentare un `[https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notprincipal.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_notprincipal.html)` elemento quando si crea una dichiarazione politica, come illustrato nella seguente dichiarazione.

```
IamPrincipal principal = IamPrincipal.create(IamPrincipalType.AWS, "arn:aws:iam::444455556666:root");
IamStatement.builder().addNotPrincipal(principal);
```
