我有一个Java客户端试图使用自签名证书访问服务器。
当我试图发布到服务器，我得到以下错误:
无法找到请求目标的有效认证路径
在对这个问题做了一些研究之后，我做了以下工作。
保存我的服务器域名为根。cer文件。 在我的Glassfish服务器的JRE中，我运行了这个: Keytool -import -alias example -keystore cacerts -file root.cer 为了检查证书是否成功添加到我的cacert，我这样做: Keytool -list -v -keystore cacerts 我可以看到证书是存在的。 然后我重新启动Glassfish并重新尝试“post”。
我还是得到同样的错误。
我有一种感觉，这是因为我的Glassfish实际上没有读取我修改过的cacert文件，但可能是其他一些文件。
你们中有人遇到过这样的问题吗，可以帮我找到正确的方向吗?
当前回答
我在试图从我的应用程序访问https url时遇到了这个错误，该应用程序正在使用自签名证书。 他们提供的是一个.cert文件，我不知道该把它放在哪里。我是这样解决的:
keytool的位置在JDK/bin文件夹下
方法1:将证书添加到默认的Java信任库- cacerts:
keytool -import -alias myCert -file C://certificate.cert -keystore C://Program Files//Java//jdk1.8.0_271//jre//lib//security//cacerts
密码:changeit
方法2:
创建信任存储:
keytool -import -alias myCert -file C://certificate.cert -keystore myTrustStore
它会给你以下提示，可以填充为:
Enter keystore password:changeit
Re-enter new password:changeit
Trust this certificate?yes
这将在运行此命令的文件夹中创建一个myTrustStore文件。 将这个“mytrustStore”复制到一个方便的位置。
使用信任存储:
当你运行你的应用程序/服务器时，传递这些JVM参数:
-Djavax.net.ssl.trustStore=C://myTrustStore -Djavax.net.ssl.trustStorePassword=changeit

eclipse / Sts用户注意:
因为eclipse使用它自己的JRE，您应该将cert添加到它自己的JRE密钥存储库中。 我有这个问题，直到我添加certs到圣的JRE。
SSL日志:
`javax.net.ssl|DEBUG|1A|restartedMain|2021-12-06 23:04:00.874` IRST|TrustStoreManager.java:113|trustStore is: D:\sts-4.12.0.RELEASE\plugins\org.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64_16.0.2.v20210721-1149\jre\lib\security\cacerts
This is the full path: "sts-4.12.0.RELEASE\plugins\org.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64_16.0.2.v20210721-1149\jre\lib\security\cacerts"
这就是我所做的。
我想在Java 10上开发应用程序，我有Eclipse IDE 2020-06。 证书导入解决方案对我不起作用。 因此，我安装了Java 11 JDK，切换到最新的Eclipse IDE(在Java 11上运行)，并通过在Maven POM下添加以下语句来确保源代码仍然可以根据Java 10编译:
<maven.compiler.target>1.10</maven.compiler.target>
<maven.compiler.source>1.10</maven.compiler.source>
<maven.compiler.release>10</maven.compiler.release>
它就像一个魔法;没有错误。
检查$JAVA_HOME/lib/security/cacerts文件是否存在! 在我的情况下，它不是一个文件，而是一个到/etc/ssl/certs/java/cacerts的链接，而且这是一个到自身的链接(什么??)，因此JVM无法找到该文件。
解决方案: 复制真正的cacerts文件(你可以从另一个JDK)到/etc/ssl/certs/java/目录，它将解决你的问题:)
这里是解决方案，按照下面的链接一步一步:
