我有一个 Java 客户端尝试使用自签名证书访问服务器。
当我尝试发布到服务器时，出现以下错误：
无法找到请求目标的有效认证路径
对这个问题进行了一些研究后，我做了以下工作。
将我的服务器域名保存为
root.cer在我的 Glassfish 服务器的 JRE 中，我运行了以下命令：
keytool -import -alias example -keystore cacerts -file root.cer
为了检查证书是否已成功添加到我的 cacert，我这样做了：
keytool -list -v -keystore cacerts
我可以看到证书存在。
然后我重新启动 Glassfish 并重试“帖子”。
我仍然遇到同样的错误。
我有一种感觉，这是因为我的 Glassfish 实际上并未读取我修改过的
cacert你们中有人遇到过这个问题并且可以将我推向正确的方向吗？
不幸的是 - 这可能是很多事情 - 并且许多应用程序服务器和其他 java“包装器”很容易使用属性和它们对钥匙串的“自己”看法等等。所以它可能会看到完全不同的东西。
缺少桁架 - 我会尝试：
java -Djavax.net.debug=all -Djavax.net.ssl.trustStore=trustStore ...
看看是否有帮助。除了“全部”之外，还可以将其设置为“ssl”、密钥管理器和信任管理器 - 这可能对您的情况有所帮助。将其设置为“帮助”将在大多数平台上列出如下所示的内容。
无论如何 - 请确保您完全理解密钥库（您拥有私钥和证明您自己身份的证书）和信任库（决定您信任的人）之间的区别 - 以及您自己的身份还有一条到根的信任“链”——它与任何到根的链都是分开的，您需要弄清楚您信任“谁”。
all turn on all debugging
ssl turn on ssl debugging
The following can be used with ssl:
record enable per-record tracing
handshake print each handshake message
keygen print key generation data
session print session activity
defaultctx print default SSL initialization
sslctx print SSLContext tracing
sessioncache print session cache tracing
keymanager print key manager tracing
trustmanager print trust manager tracing
pluggability print pluggability tracing
handshake debugging can be widened with:
data hex dump of each handshake message
verbose verbose handshake message printing
record debugging can be widened with:
plaintext hex dump of record plaintext
packet print raw SSL/TLS packets

您需要配置 JSSE 系统属性，特别是指向客户端证书存储。
通过命令行：
java -Djavax.net.ssl.trustStore=truststores/client.ts com.progress.Client
或通过Java代码：
import java.util.Properties;
...
Properties systemProps = System.getProperties();
systemProps.put("javax.net.ssl.keyStorePassword","passwordForKeystore");
systemProps.put("javax.net.ssl.keyStore","pathToKeystore.ks");
systemProps.put("javax.net.ssl.trustStore", "pathToTruststore.ts");
systemProps.put("javax.net.ssl.trustStorePassword","passwordForTrustStore");
System.setProperties(systemProps);
...

使用 java 软件发行版中的 cli 实用程序 keytool 导入（和信任！）所需的证书
样品：
从 cli 将 dir 更改为 jre in
检查密钥库（在目录中的 jre 中找到的文件）
keytool -list -keystore ..\lib\securit
