Java 没有可用的X509TrustManager实现

我正在调用一个AWSAPI，我一直遇到以下错误

我在Stackoverflow上浏览了多个线程，并添加了所有必需的truststore、truststoretype系统属性。这个我已经试过了。但一切都不起作用。有人见过这个吗？我是这样调用它的

TrustManagerFactory tmf = TrustManagerFactory
                                   .getInstance(TrustManagerFactory.getDefaultAlgorithm());

KeyStore ks  = KeyStore.getInstance("BCFKS");
ks.load(new FileInputStream("<jre-home>\\\\lib\\\\security\\\\cacerts"), "changeit".toCharArray());
tmf.init(ks);

 // Get hold of the trust manager
X509TrustManager x509Tm = null;
for (TrustManager tm : tmf.getTrustManagers()) {
     if (tm instanceof X509TrustManager) {
          x509Tm = (X509TrustManager) tm;
          break;
     }
}

TrustManagerFactory tmf=TrustManagerFactory
.getInstance（TrustManagerFactory.getDefaultAlgorithm（））；
KeyStore ks=KeyStore.getInstance（“BCFKS”）；
load（新文件输入流（“\\\\lib\\\\security\\\\cacerts”），“changeit.toCharArray（））；
tmf.init（ks）；
//找到信托经理
X509TrustManager x509Tm=null；
for（TrustManager tm:tmf.getTrustManagers（））{
if（X509TrustManager的tm实例）{
x509Tm=（X509TrustManager）tm；
打破
}
}

当我们在设置信任存储密码后将AWS客户端初始化移动到一个位置时，这一问题得到了解决。在我的代码中，我创建AWS客户端太早了

在调试了几个小时后，我发现它是一个损坏的密钥库。检查是否可以使用keytool命令列出密钥库的内容。

您是如何调用它的？BCFKS for bouncy castle？如果要使用默认类型的ks，

KeyStore ks=KeyStore.getInstance（KeyStore.getDefaultType（））

Yes BCFKS for bouncy castleTry打印所有信任管理器，并查看是否有多个。第一个似乎是

DummyX509TrustManager

。如果provider为null，您是否尝试将其设置为Security？如果为null，则

Security.addProvider（newyourprovider（））？
