Spring-SAML:传入的 SAML 消息无效

本文介绍了Spring-SAML:传入的 SAML 消息无效的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在将应用与 SAML 集成时遇到问题.

I am facing an issue while integrating my app with SAML.

以下是我的错误:

org.springframework.security.saml.SAMLProcessingFilter.attemptAuthentication: Incoming SAML message is invalid
org.opensaml.common.SAMLException: Endpoint with message binding urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST and URL https://myappruldotom/saml/SSO wasn't found in local metadata at org.springframework.security.saml.util.SAMLUtil.getEndpoint(SAMLUtil.java:357) ~[spring-security-saml2-core-1.0.2.RELEASE.jar:1.0.2.RELEASE]

我的应用程序部署在 AWS 上，当我通过编写自定义 SAMLProcessingFilter 添加日志语句并编写 getEndpoint() 的实现以添加多个日志语句并复制 getEndpoint() 方法的确切内容时.

My app is deployed on AWS and when i added the log statement in by writing the custom SAMLProcessingFilter and wrote implementation of getEndpoint() to add multiple log statements and copied the exact content of getEndpoint() method.

日志语句显示端点以 IP 地址的形式出现:MySAMLProcessingFilter.getEndpoint: MySAMLLOG - endpoint.getLocation() = https://10.193.160.123:443/mysamlapp/saml/SSO

The log statement shows that the endpoint is coming as IP address :MySAMLProcessingFilter.getEndpoint: MySAMLLOG - endpoint.getLocation() = https://10.193.160.123:443/mysamlapp/saml/SSO

我在我的 SAML 配置中定义了 entityId，但这也没有帮助.我的配置文件中的 entityId 为:

I have defined entityId in my SAML config, but this also didn't help. entityId in my config file as :

<bean id="metadataGeneratorFilter" class="org.springframework.security.saml.metadata.MetadataGeneratorFilter">
    <constructor-arg>
        <bean class="org.springframework.security.saml.metadata.MetadataGenerator">
            <property name="entityId" value="https://myappruldotom/mysamlapp/saml/metadata"/>
            <property name="requestSigned" value="false"/>
        </bean>
    </constructor-arg>
</bean>

推荐答案

要解决此问题，请在 metadataGeneratorFilter bean 中设置 MetadataGenerator 的 enityBaseURL 属性.代码如下:

To fix this issue, set the enityBaseURL property of MetadataGenerator inside metadataGeneratorFilter bean. Code looks like this : 

<bean id="metadataGeneratorFilter" class="org.springframework.security.saml.metadata.MetadataGeneratorFilter">
        <constructor-arg>
            <bean class="org.springframework.security.saml.metadata.MetadataGenerator">
                <property name="entityId" value="http://myapp.com/myapp/saml/metadata"/>
                <property name="requestSigned" value="false"/>
                <property name="entityBaseURL" value="http://myapp.com/myapp"/>
            </bean>
        </constructor-arg>
    </bean>
