OpenSAML / Spring 安全设置，因此在 Tomcat 上重新部署有效

Question

我们是运行 OpenJDK IcedTea6 1.13.6 上使用 Tomcat 6.0.35 的网络应用程序。对于 SSO，我们使用 Spring 安全 SAML 扩展，它基于 OpenSAML 2.6.1。

重新部署我们的应用程序时（无需重新启动 Tomcat），我得到一个 NoClassDefFoundError：org/bouncycastle/crypto/paddings/ISO10126d2Padding 描述得非常好 here。从 Eclipse MAT 分析中，我了解到 BouncyCastleProvider 或 JCERSAPublicKey 正在阻止 WebappClassLoader 被 gc'ed。

如何配置 SAML 以便正确销毁所有（充气城堡）实例？我很难相信 SAML 的设计使得部署要求 Tomcat 重新启动。

我目前的配置： ...

<bean id="samlLogger" class="org.springframework.security.saml.log.SAMLDefaultLogger">
    <property name="logErrors" value="true"/>
    <property name="logMessages" value="true"/>
</bean>

<bean id="keyManager" class="org.springframework.security.saml.key.JKSKeyManager">
    <constructor-arg value="classpath:security/samlKeystore.jks"/>
    <constructor-arg type="java.lang.String" value="mypassword"/>
    <constructor-arg>
        <map>
            <entry key="tenzingfaces" value="keyphrase"/>
        </map>
    </constructor-arg>
    <constructor-arg type="java.lang.String" value="tenzingfaces"/>
</bean>

<bean id="samlEntryPoint" class="org.springframework.security.saml.SAMLEntryPoint">
    <property name="defaultProfileOptions">
        <bean class="org.springframework.security.saml.websso.WebSSOProfileOptions">
            <property name="binding" value="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST"/>
            <property name="includeScoping" value="false"/>
        </bean>
    </property>
</bean>

<bean id="metadataDisplayFilter" class="org.springframework.security.saml.metadata.MetadataDisplayFilter"/>

<bean id="samlAuthenticationProvider" class="org.springframework.security.saml.SAMLAuthenticationProvider">
    <property name="userDetails" ref="samlUserDetailService" />
    <property name="forcePrincipalAsString" value="false" />
</bean>

<bean id="samlUserDetailService" class="ch.umbrella.springframework.security.SamlUserDetailsServiceImpl" />

<bean id="contextProvider" class="org.springframework.security.saml.context.SAMLContextProviderImpl"/>

<bean id="samlSuccessRedirectHandler" class="ch.umbrella.springframework.security.SsoAuthenticationSuccessHandler" >
    <property name="defaultTargetUrl" value="/main.html" />
    <property name="alwaysUseDefaultTargetUrl" value="false" />
    <property name="credentialsExpiredUrl" value="/credentialsexpired.html" />
</bean>
<bean id="samlWebSSOProcessingFilter" class="org.springframework.security.saml.SAMLProcessingFilter">
    <property name="authenticationManager" ref="authenticationManager"/>
    <property name="authenticationSuccessHandler" ref="samlSuccessRedirectHandler"/>
</bean>

<bean id="processor" class="org.springframework.security.saml.processor.SAMLProcessorImpl">
    <constructor-arg>
        <list>
            <ref bean="redirectBinding"/>
            <ref bean="postBinding"/>
        </list>
    </constructor-arg>
</bean>

<bean id="webSSOprofileConsumer" class="org.springframework.security.saml.websso.WebSSOProfileConsumerImpl"/>
<bean id="hokWebSSOprofileConsumer" class="org.springframework.security.saml.websso.WebSSOProfileConsumerHoKImpl"/>
<bean id="webSSOprofile" class="org.springframework.security.saml.websso.WebSSOProfileImpl"/>
<bean id="hokWebSSOProfile" class="org.springframework.security.saml.websso.WebSSOProfileConsumerHoKImpl"/>

<bean id="postBinding" class="org.springframework.security.saml.processor.HTTPPostBinding">
    <constructor-arg ref="parserPool"/>
    <constructor-arg ref="velocityEngine"/>
</bean>

<bean id="velocityEngine" class="org.springframework.security.saml.util.VelocityFactory" factory-method="getEngine"/>

<bean id="redirectBinding" class="org.springframework.security.saml.processor.HTTPRedirectDeflateBinding">
    <constructor-arg ref="parserPool"/>
</bean>

<bean class="org.springframework.security.saml.SAMLBootstrap"/>

<bean id="parserPool" class="org.opensaml.xml.parse.StaticBasicParserPool" scope="singleton" init-method="initialize"/>
<bean id="parserPoolHolder" class="org.springframework.security.saml.parser.ParserPoolHolder" scope="singleton"/>
...

并且，在特定于暂存的文件中：

<bean id="metadata" class="org.springframework.security.saml.metadata.CachingMetadataManager">
    <constructor-arg>
        <list>
            <bean class="org.springframework.security.saml.metadata.ExtendedMetadataDelegate" destroy-method="destroy">

如果您将 bouncycastle 罐子捆绑在 war 中，则不要那样做。而是将这些罐子放在 tomcat/lib 中。希望这能解决问题。
