(转载自我的其他回复) 使用java软件发行版中的cli实用工具keytool导入(并信任!)所需的证书

示例:

从命令行更改目录到jre\bin 检查密钥库(在jre\bin目录中找到的文件) Keytool -list -keystore ..\lib\security\cacerts . txt 密码为changeit 从需要的服务器下载并保存链中的所有证书。 添加证书(在需要删除文件..\lib\security\cacerts上的“只读”属性之前)，运行: keytool -alias REPLACE_TO_ANY_UNIQ_NAME -import -keystore.使用实例\lib\security\cacerts -file "r:\root.crt"

我偶然发现了这么一个简单的小窍门。 其他解决方案需要使用InstallCert.Java和JDK

JDK 8迁移到JDK 10时的解决方案

证书是非常不同的 JDK 10有80个，而JDK 8有151个 JDK 10最近添加了certs https://dzone.com/articles/openjdk-10-now-includes-root-ca-certificates http://openjdk.java.net/jeps/319

JDK 10

root@c339504909345:/opt/jdk-minimal/jre/lib/security #  keytool -cacerts -list
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 80 entries

JDK 8

root@c39596768075:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts #  keytool -cacerts -list
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 151 entries

修复步骤

我删除了JDK 10证书，并将其替换为JDK 8 由于我正在构建Docker图像，我可以使用多阶段构建快速完成 我正在使用jlink作为/opt/jdk/bin/jlink \构建一个最小的JRE ——模块路径/ opt / jdk / jmods……

这里是不同的路径和命令的顺序…

# Java 8
COPY --from=marcellodesales-springboot-builder-jdk8 /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts /etc/ssl/certs/java/cacerts

# Java 10
RUN rm -f /opt/jdk-minimal/jre/lib/security/cacerts
RUN ln -s /etc/ssl/certs/java/cacerts /opt/jdk-minimal/jre/lib/security/cacerts

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:)

I am working on a tutorial for REST web services at www.udemy.com (REST Java Web Services). The example in the tutorial said that in order to have SSL, we must have a folder called "trust_store" in my eclipse "client" project that should contain a "key store" file (we had a "client" project to call the service, and "service" project that contained the REST web service - 2 projects in the same eclipse workspace, one the client, the other the service). To keep things simple, they said to copy "keystore.jks" from the glassfish app server (glassfish\domains\domain1\config\keystore.jks) we are using and put it into this "trust_store" folder that they had me make in the client project. That seems to make sense: the self-signed certs in the server's key_store would correspond to the certs in the client trust_store. Now, doing this, I was getting the error that the original post mentions. I have googled this and read that the error is due to the "keystore.jks" file on the client not containing a trusted/signed certificate, that the certificate it finds is self-signed.

为了让事情更清楚，让我说一下我理解的“密钥库”。“Jks”包含自签名的certs，以及“cacerts. Jks”。“jks”文件中包含CA证书(由CA签名)。“密钥存储库。Jks是“密钥存储库”，cacerts是“cacerts”。Jks”是“信任商店”。正如一位名叫“布鲁诺”的评论者所说，“密钥库。Jks是本地的，cacerts是本地的。Jks”用于远程客户端。

So, I said to myself, hey, glassfish also has the "cacerts.jks" file, which is glassfish's trust_store file. cacerts.jsk is supposed to contain CA certificates. And apparently I need my trust_store folder to contain a key store file that has at least one CA certificate. So, I tried putting the "cacerts.jks" file in the "trust_store" folder I had made, on my client project, and changing the VM properties to point to "cacerts.jks" instead of "keystore.jks". That got rid of the error. I guess all it needed was a CA cert to work.

这对于生产来说可能并不理想，甚至对于开发来说也不理想。例如，您可以使用“keytool”命令将CA证书添加到“密钥存储库”中。Jks”文件在客户端。但无论如何，希望这至少能缩小可能导致错误的情况。

另外:我的方法似乎对客户端有用(服务器证书添加到客户端trust_store)，看起来上面解决原始帖子的注释对服务器有用(客户端证书添加到服务器trust_store)。欢呼。

Eclipse项目设置:

MyClientProject src 测验 JRE系统库 .．. trust_store ——cacerts.jks ——keystore.jks

MyClientProject.java文件片段:

static {
  // Setup the trustStore location and password
  System.setProperty("javax.net.ssl.trustStore","trust_store/cacerts.jks");
  // comment out below line
  System.setProperty("javax.net.ssl.trustStore","trust_store/keystore.jks");
  System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
  //System.setProperty("javax.net.debug", "all");

  // for localhost testing only
  javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(new javax.net.ssl.HostnameVerifier() {
        public boolean verify(String hostname, javax.net.ssl.SSLSession sslSession) {
          return hostname.equals("localhost");
        }

  });
}

在这个问题上浪费了很多时间。如果您导入了证书，您可以看到这里列出了它。

keytool -list -v -keystore $JAVA_HOME/lib/security/cacerts

然后创建新的文件，使用以下命令替换SITE_NAME、SITE_PORT、CERTIFICATE_NAME和保存文件的路径。

echo -n | openssl s_client -connect SITE_NAME:SITE_PORT  \
| openssl x509 > /path/to/save/CERTIFICATE_NAME.cert

就我而言，我在Spring中使用Keycloak时遇到了问题。在我用这个命令创建证书并导入到密钥存储库之后，问题就解决了，它可以正常工作

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。
