我一直在努力让Spring SAML Sample应用程序启动并运行，但已经挣扎了好几天，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....当我点击“开始单点登录”时按钮，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：

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使用空密码或密码＆＃34; changeit ＆＃34;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。
答案 2 :(得分：1)
我在使用Java 1.6的Mac上 - 这就是我发现的：
TrustMaterial.java正在运行静态初始化代码 - ＆gt;
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行的这一行会导致NPE，因为JSSE_CACERTS为空：
this.jks = CACERTS != null ? CACERTS.jks : JSSE_CACERTS.jks;
那么，为什么都是null？
当我在文件系统上查看我的文件时：
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的破坏符号链接/ cacerts中
这是无效cacerts密钥库的符号链接。我所做的是通过以下命令获得JDK1.6密钥库的良好副本：
sudo find / -name 'cacerts' 2>/dev/null
/一些/其他/路径/到/ cacerts中
然后，执行file /some/other/path/to/cacerts以确保您获得有效的文件：
/ 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否正常：
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。
屁股真痛苦。
答案 3 :(得分：0)
我在openjdk11中遇到了这个问题或非常类似的问题，原来是这个错误：
https://github.com/narupley/not-going-to-be-commons-ssl/issues/5
defaultKeystoreType是pkcs12（似乎是在较新的Java版本中），并且在不常见的0.3.19中似乎存在一个错误，导致此问题，因为pkcs12（而不是jks）需要输入密码才能看到证书。
