“PKIX路径构建失败”和“无法找到请求目标的有效认证路径”

我试图使用twitter4j库为我的java项目获得推文，它在封面下使用java.net.HttpURLConnection(可以在堆栈跟踪中看到)。在我第一次运行时，我得到了一个关于证书sun.security.validator.ValidatorException和sun.security.provider.certpath.SunCertPathBuilderException的错误。然后我添加了twitter证书:

C:\Program Files\Java\jdk1.7.0_45\jre\lib\security>keytool -importcert -trustcacerts -file PathToCert -alias ca_alias -keystore "C:\Program Files\Java\jdk1.7.0_45\jre\lib\security\cacerts"

但是没有成功。以下是获取推文的流程:

public static void main(String[] args) throws TwitterException {
    ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setDebugEnabled(true)
        .setOAuthConsumerKey("myConsumerKey")
        .setOAuthConsumerSecret("myConsumerSecret")
        .setOAuthAccessToken("myAccessToken")
        .setOAuthAccessTokenSecret("myAccessTokenSecret");
    
    TwitterFactory tf = new TwitterFactory(cb.build());
    Twitter twitter = tf.getInstance();
    
    try {
        Query query = new Query("iphone");
        QueryResult result;
        result = twitter.search(query);
        System.out.println("Total amount of tweets: " + result.getTweets().size());
        List<Status> tweets = result.getTweets();
        
        for (Status tweet : tweets) {
            System.out.println("@" + tweet.getUser().getScreenName() + " : " + tweet.getText());
        }
    } catch (TwitterException te) {
        te.printStackTrace();
        System.out.println("Failed to search tweets: " + te.getMessage());
    }

这里是错误:

当前回答

问题是，您的eclipse无法连接实际上它正在尝试连接的站点。我也遇到过类似的问题，下面给出的解决方案对我来说很有效。

关闭任何第三方互联网安全应用程序，如Zscaler 有时也需要断开VPN如果你是连接的。

谢谢

其他回答

当java应用程序试图与另一个应用程序/站点通信时，如果您在linux容器中看到此问题，这是因为证书已错误地导入到负载均衡器中。导入证书需要遵循一系列步骤，如果操作不正确，您将看到如下问题

Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid 
certification path to requested target

一旦正确地导入了证书，就应该这样做。不需要修补任何JDK证书。

我们得到上述错误的原因是，JDK与许多受信任的证书颁发机构(CA)证书捆绑在一个名为“cacerts”的文件中，但该文件没有我们自签名证书的任何提示。换句话说，cacerts文件没有导入我们的自签名证书，因此没有将其视为受信任的实体，因此给出了上述错误。

如何修复上述错误

要修复上述错误，只需将自签名证书导入cacerts文件。

首先，找到cacerts文件。我们需要找到JDK的位置。如果您正在通过Eclipse或IntelliJ Idea等IDE运行应用程序，请进入项目设置并找出JDK的位置。例如，在Mac操作系统上，cacerts文件的典型位置是这个位置/Library/Java/JavaVirtualMachines/ {{JDK_version}}/Contents/Home/jre/lib/security 在windows的机器上，它将在{{Installation_directory}}/{{JDK_version}}/jre/lib/security下

找到cacerts文件后，现在我们需要将自签名证书导入到这个cacerts文件中。如果您不知道如何正确生成自签名证书，请查看上一篇文章。

如果你没有一个证书文件(.crt)，只有一个.jks文件，你可以使用下面的命令生成一个.crt文件。如果你已经有了。crt/。Pem文件，那么你可以忽略下面的命令

##从密钥库生成证书。JKS文件)####

keytool -export -keystore keystore.jks -alias selfsigned -file selfsigned.crt

以上步骤将生成一个名为selfsigned.crt的文件。现在将证书导入cacerts

Now add the certificate to JRE/lib/security/cacerts (trustore)

keytool -importcert -file selfsigned.crt -alias selfsigned -keystore {{cacerts path}}

对如

keytool -importcert -file selfsigned.nextgen.crt -alias selfsigned.nextgen -keystore /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/security/cacerts

这就是全部，重新启动应用程序，它应该可以正常工作。如果它仍然不工作，并获得SSL握手异常。这可能意味着您正在使用不同的域名，然后在证书中注册。

问题背景:

当我试图在我的项目中运行mvn清洁安装并通过Netbeans IDE清洁和构建选项时，我得到了以下错误。此问题是由于通过NET beans IDE/通过命令提示符下载时证书不可用，但可以通过浏览器下载文件。

错误:

Caused by: org.eclipse.aether.transfer.ArtifactTransferException: Could not transfer artifact com.java.project:product:jar:1.0.32 from/to repo-local (https://url/local-repo): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

解决方法:

1. 下载有关网址的证书:

Launch IE by "run as adminstrator" (otherwise, we will not be able to download the certificate) Enter the url in IE-> https://url/local-repo (In my case this url had a untrusted certificate.) Download the certificate by clicking on Certificate error -> view certificate Select Details tab -> copy to file -> next -> select "DER encoded binary X.509 (.CER) save the certificate in some location, example : c:/user/sheldon/desktop/product.cer Congrats! you have successfully downloaded the certificate for the site

2. 现在安装密钥存储库以修复该问题。

运行keytool命令将下载的密钥存储库附加到已存在的证书文件。命令:jdk (JAVA_HOME) bin文件夹下的如下命令。

C:\Program Files\Java\ jdk1.8.0_141\jre\bin>keytool -importcert -file .使用实例 “C: / user /谢耳朵/桌面/产品。-alias product -keystore “C: /程序文件/ Java / jdk1.8.0_141 / jre / lib /安全/除”。

系统将提示您输入密码。输入keystore密码: 再次输入“changeit”，输入“信任此证书?”(没有):“,输入 “是的”

示例命令行命令/输出:

keytool -importcert -file "C:/Users/sheldon/Desktop/product.cer" -alias product -keystore "C:/Program iles/Java/jdk1.8.0_141/jre/lib/security/cacerts"
Enter keystore password:
Trust this certificate? [no]:  yes
Certificate was added to keystore

Contgrats !现在你应该删除“PKIX路径构建失败:sun.security.provider.certpath”。在Netbeans IDE中出现SunCertPathBuilderException错误。

我也遇到了同样的问题，我使用的是8.1.0-3，但后来我使用了9.2.1-0，这个问题在没有任何手动步骤的情况下得到了修复。自签名证书工作正常。

2020-03-12 06:36:57

我的UI方法:

从这里下载密钥库资源管理器打开$ JAVA_HOME / jre / lib /安全/除输入PW: changeit(可以在Mac上changeme) 导入.crt文件

CMD-Line:

Keytool -importcert -file jetty。crt -alias jetty -keystore $JAVA_HOME/jre/lib/security/cacerts . crt -alias jetty -keystore $JAVA_HOME/jre/lib/security/cacerts . crt 输入PW: changeit(可以在Mac上changeme)
