我一直试图让Spring SAML Sample应用程序启动并运行，但是已经苦苦挣扎了几天，并且在互联网上搜索没有成功。我已按照快速入门指南中的所有步骤操作....当我单击“开始单点登录”按钮时，我被重定向到SSOCircle，我登录，并被重定向回示例应用程序，但它返回以下错误：

任何帮助将非常感激！
您最有可能遇到底层OpenSAML和SSL库中的错误，该错误假定文件JAVA_HOME/lib/security/cacerts或JAVA_HOME/lib/security/jssecacerts存在并且可以作为JKS或PKCS12密钥库读取。在您的情况下，该文件可能已损坏。
请尝试使用原始安装中的文件更新JDK中的cacerts文件。确保您可以使用keytool -list -keystore cacerts以空密码或密码“changeit”来阅读它。
同样的问题，从捆绑的3.9 saml-sample升级到not-yet-commons-ssl-0.3.16.jar并且它有效。
我在使用Java 1.6的Mac上 - 这就是我发现的：
TrustMaterial.java正在运行静态init代码 - >
String pathToCacerts = javaHome + "/lib/security/cacerts";
String pathToJSSECacerts = javaHome + "/lib/security/jssecacerts";
TrustMaterial cacerts = null;
TrustMaterial jssecacerts = null;
try {
File f = new File(pathToCacerts);
if (f.exists()) {
cacerts = new TrustMaterial(pathToCacerts);
}
}
catch (Exception e) {
e.printStackTrace();
}
try {
File f = new File(pathToJSSECacerts);
if (f.exists()) {
jssecacerts = new TrustMaterial(pathToJSSECacerts);
}
}
catch (Exception e) {
e.printStackTrace();
}
CACERTS = cacerts;
JSSE_CACERTS = jssecacerts;
if (JSSE_CACERTS != null) {
DEFAULT = JSSE_CACERTS;
} else {
DEFAULT = CACERTS;
}
现在，上面提到了一个关于假设JAVA_HOME/lib/security/...文件是有效密钥库的错误。如果这些文件都不是有效的密钥库，则CACERTS和JSSE_CACERTS都为空，第127行的这一行导致NPE，因为JSSE_CACERTS为null：
this.jks = CACERTS != null ? CACERTS.jks : JSSE_CACERTS.jks;
那么，为什么都是null？
当我在我的文件系统上查看我的文件：
file /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security/cacerts
我明白了：
/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security/cacerts：/ System/Library/Java/Support/CoreDeploy.bundle/Contents/Home/lib/security/cacerts的破坏符号链接
这是无效cacerts密钥库的符号链接。我所做的是通过此命令获得JDK1.6密钥库的良好副本：
sudo find / -name 'cacerts' 2>/dev/null
/一些/其它/路径/到/ cacerts的
然后，执行file /some/other/path/to/cacerts以确保获得有效文件：
/ some / other / path / to / cacerts：Java KeyStore
将其复制到/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security/cacerts以替换损坏的符号链接并验证它是好的：
file /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security/cacerts
/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security/cacerts:Java KeyStore
一旦这是一个有效的密钥库，这个代码就可以了。
屁股多么痛苦。
