<div class="block">
<span>用于从头开始创建<a href="../../../../javax/xml/crypto/dsig/XMLSignature.html" title="javax.xml.crypto.dsig中的接口"><code>XMLSignature</code></a>对象的工厂，或从对应的XML表示中解组<code>XMLSignature</code>对象。</span>
<h2> <span>XMLSignatureFactory类型</span> </h2>
<p> <span><code>XMLSignatureFactory</code>每个实例<code>XMLSignatureFactory</code>支持特定的XML机制类型。</span> <span>要创建一个<code>XMLSignatureFactory</code> ，请调用静态<a href="../../../../javax/xml/crypto/dsig/XMLSignatureFactory.html#getInstance-java.lang.String-"><code>getInstance</code></a>方法之一，传递所需的XML机制类型，例如：</span> </p>
<blockquote>
<span><code> XMLSignatureFactory factory = XMLSignatureFactory.getInstance("DOM"); </code></span>
</blockquote>
<p> <span>该工厂生产的对象将基于DOM，并遵守API概述中<a href="../../../../../technotes/guides/security/xmldsig/overview.html#DOM Mechanism Requirements">DOM Mechanism Requirements</a>部分定义的DOM互操作性要求。</span> <span>有关标准机制类型的列表，请参阅API概述的<a href="../../../../../technotes/guides/security/xmldsig/overview.html#Service Provider">Service Providers</a>部分。</span> </p>
<p> <span><code>XMLSignatureFactory</code>机制注册和加载<a href="../../../../java/security/Provider.html" title="java.security中的类">XMLSignatureFactory</a>实现。</span> <span>例如，支持DOM机制的服务提供商将在<code>Provider</code>子类中<code>Provider</code>为：</span> </p>
<pre>  <span>put("XMLSignatureFactory.DOM", "org.example.DOMXMLSignatureFactory");</span> </pre>
<p> <span>实现必须最低限度地支持默认机制类型：DOM。</span> </p>
<p> <span>注意，调用者必须使用相同<code>XMLSignatureFactory</code>实例创建<code>XMLStructure</code>个特定的<code>XMLSignature</code>即产生。</span> <span>如果来自不同提供商的<code>XMLStructure</code> s或不同的机制类型一起使用，行为是未定义的。</span> </p>
<p> <span>此外，由本厂创建的<code>XMLStructure</code> s可能包含特定于<code>XMLSignature</code>状态，并不意图重复使用。</span> </p>
<h2> <span>从头创建XMLSignatures</span> </h2>
<p> <span>一旦创建了<code>XMLSignatureFactory</code> ，可以通过调用相应的方法来实例化对象。</span> <span>例如，可以通过调用<a href="../../../../javax/xml/crypto/dsig/XMLSignatureFactory.html#newReference-java.lang.String-javax.xml.crypto.dsig.DigestMethod-"><code>newReference</code></a>方法之一来创建一个<a href="../../../../javax/xml/crypto/dsig/Reference.html" title="javax.xml.crypto.dsig中的接口"><code>Reference</code></a>实例。</span> </p>
<h2> <span>从XML解组XMLSignatures</span> </h2>
<p> <span>可替换地， <code>XMLSignature</code>可以从现有的XML表示通过调用创建<a href="../../../../javax/xml/crypto/dsig/XMLSignatureFactory.html#unmarshalXMLSignature-javax.xml.crypto.dsig.XMLValidateContext-"><code>unmarshalXMLSignature</code></a>方法并传递它的特定机制- <a href="../../../../javax/xml/crypto/dsig/XMLValidateContext.html" title="javax.xml.crypto.dsig中的接口"><code>XMLValidateContext</code></a>包含XML内容实例：</span> </p>
<pre>  <span>DOMValidateContext context = new DOMValidateContext(key, signatureElement);
 XMLSignature signature = factory.unmarshalXMLSignature(context);</span> </pre>
<span>每个<code>XMLSignatureFactory</code>必须支持该工厂类型所需的<code>XMLValidateContext</code>类型，但可能支持其他类型。</span>
<span>DOM <code>XMLSignatureFactory</code>必须支持<a href="../../../../javax/xml/crypto/dsig/dom/DOMValidateContext.html" title="javax.xml.crypto.dsig.dom中的类"><code>DOMValidateContext</code></a>对象。</span>
<h2> <span>将XMLSignatures签名和编组为XML</span> </h2>
<span>工厂创建的每个<code>XMLSignature</code>也可以通过调用<a href="../../../../javax/xml/crypto/dsig/XMLSignature.html" title="javax.xml.crypto.dsig中的接口"><code>XMLSignature</code></a>对象的<a href="../../../../javax/xml/crypto/dsig/XMLSignature.html#sign-javax.xml.crypto.dsig.XMLSignContext-"><code>sign</code></a>方法，并传递给包含签名密钥和编组参数的机制特定<a href="../../../../javax/xml/crypto/dsig/XMLSignContext.html" title="javax.xml.crypto.dsig中的接口"><code>XMLSignContext</code></a>对象（见<a href="../../../../javax/xml/crypto/dsig/dom/DOMSignContext.html" title="javax.xml.crypto.dsig.dom中的类"><code>DOMSignContext</code></a> ），编组为XML表示并签名。</span>
<span>例如：</span>
<pre>  <span>DOMSignContext context = new DOMSignContext(privateKey, document);
    signature.sign(context);</span> </pre>
<span><b>并发访问</b></span>
<p> <span>该类的静态方法保证线程安全。</span> <span>多个线程可以同时调用此类中定义的静态方法，而不会产生不良影响。</span> </p>
<p> <span>但是，对于此类定义的非静态方法，这不是真的。</span> <span>除非特定提供商另有说明，否则需要同时访问单个<code>XMLSignatureFactory</code>实例的线程应在其间同步并提供必要的锁定。</span> <span>多个线程每个操作不同的<code>XMLSignatureFactory</code>实例不需要同步。</span> </p>
