opensaml 怎么获取 AttributeStatement 代码

要使用 OpenSAML 库创建 AttributeStatement 并将其转换为字符串形式的代码,你可以按照以下步骤进行:
1. 创建 AttributeStatement 对象:
```java
SAMLObjectBuilder<AttributeStatement> attributeStatementBuilder =
(SAMLObjectBuilder<AttributeStatement>) builderFactory.getBuilder(AttributeStatement.DEFAULT_ELEMENT_NAME);
AttributeStatement attributeStatement = attributeStatementBuilder.buildObject();
```
2. 创建 Attribute 对象:
```java
SAMLObjectBuilder<Attribute> attributeBuilder =
(SAMLObjectBuilder<Attribute>) builderFactory.getBuilder(Attribute.DEFAULT_ELEMENT_NAME);
Attribute attribute = attributeBuilder.buildObject();
attribute.setName("attributeName");
attribute.setNameFormat(Attribute.URI_REFERENCE);
```
3. 创建 AttributeValue 对象:
```java
SAMLObjectBuilder<XSString> stringBuilder =
(SAMLObjectBuilder<XSString>) builderFactory.getBuilder(XSString.TYPE_NAME);
XSString attributeValue = stringBuilder.buildObject(AttributeValue.DEFAULT_ELEMENT_NAME, XSString.TYPE_NAME);
attributeValue.setValue("attributeValue");
```
4. 将 AttributeValue 添加到 Attribute 中:
```java
attribute.getAttributeValues().add(attributeValue);
```
5. 将 Attribute 添加到 AttributeStatement 中:
```java
attributeStatement.getAttributes().add(attribute);
```
6. 将 AttributeStatement 对象转换为字符串形式的代码:
```java
Marshaller marshaller = marshallerFactory.getMarshaller(attributeStatement);
Element attributeStatementElement = marshaller.marshall(attributeStatement);
StringWriter writer = new StringWriter();
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.transform(new DOMSource(attributeStatementElement), new StreamResult(writer));
String attributeStatementCode = writer.toString();
```
在这个示例中,首先使用 `SAMLObjectBuilder` 创建 `AttributeStatement`、`Attribute` 和 `AttributeValue` 对象。然后,设置 `Attribute` 和 `AttributeValue` 的属性和值,并将 `AttributeValue` 添加到 `Attribute` 中,将 `Attribute` 添加到 `AttributeStatement` 中。最后,使用 `Marshaller` 将 `AttributeStatement` 对象转换为 DOM 元素,并将 DOM 元素转换为字符串形式的代码。代码存储在 `attributeStatementCode` 变量中。
