“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:

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

当前回答

解决这个异常的简单步骤，(我在java 11上做的)，

First you need to Download the public SSL certificate file of the target domain that you are trying to call,for that Open the target domain website in the chrome (Example: https://amazonservice.domain.com) Click on the small lock icon before the URL in the browser Click View certificates Now Click on Certificate is valid as shown below Now a new Popup will open as shown below, Open the details tab Select the RootCert at the top Click Export and save the .cer file to your system in a directory

现在您有了目标域的公共密钥存储库，您正在尝试在java应用程序中调用该密钥存储库，现在我们需要将该密钥存储库导入您的jre，为此转到$JAVA_HOME/bin目录并运行以下命令

./keytool -importcert -alias someAliasName -keystore {JAVA_HOME}/lib/security/cacerts -file {PathToDownloads}/certificateFileName.cer

它会要求您输入密码，如果您知道，请输入密码，证书的默认密码是changeit

其他回答

在这里，这种异常通常发生在受信任证书的PATH不匹配时。检查用于安全通信的服务器证书所需的配置或路径。

将JDK版本从旧的jdk1.8.0_90版本更改为最新版本jdk1.8.0_239 如上所述，回答将证书导入keystore 向gradle添加密钥库属性。属性文件在java/react原生android基于项目

systemProp.javax.net.ssl.trustStore=C：//Program Files//AdoptOpenJDK//jdk-8.0.282.8-hotspot//jre//lib//security//cacerts systemProp.javax.net.ssl.trustStorePassword=changeit

这是针对Glassfish服务器的:

通常Glassfish会看着仙人掌。证书文件存放在GLASSFISH_SERVER\glassfish\domains\domain1\config目录下。您可以更改此配置或替换cacerts。JKS文件和cacerts文件。

Glassfish使用了一些默认的JVM选项:

 -XX:+UnlockDiagnosticVMOptions
 -XX:NewRatio=2
 -XX:MaxPermSize=192m
 -Xmx512m
 -client
 -javaagent:C:/glassfish5/glassfish/lib/monitor/flashlight-agent.jar
 -Djavax.xml.accessExternalSchema=all
 -Djavax.net.ssl.trustStore=C:\glassfish5\glassfish\domains\domain1/config/cacerts.jks
 -Djdk.tls.rejectClientInitiatedRenegotiation=true
 -Djdk.corba.allowOutputStreamSubclass=true

如果您在Spring Tools Suite或Eclipse等IDE中遇到此错误，请首先尝试使用URL的HTTP版本而不是HTTPS版本。

当我试图将SonarQube链接添加到Spring Tools Suite时，我遇到了这个错误。我将我的URL替换为:

http://sonarqube...

而不是

https://sonarqube...

我已经成功连接SonarQube。

我希望它能对那些像我一样在寻找这个问题答案的人有所帮助。

我在尝试通过Eclipse的更新站点在Eclipse中安装Cucumber-Eclipse插件时遇到了这个问题。我收到了同样的SunCertPathBuilderException错误:

Unable to read repository at http://cucumber.io/cucumber-eclipse/update-site/content.xml.
    Unable to read repository at http://cucumber.io/cucumber-eclipse/update-site/content.xml.
    sun.security.validator.ValidatorException: PKIX path building failed: 
   sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

虽然其他一些答案在这个问题的特定情况下是合适和有用的，但它们对我的问题没有帮助和误导。

在我的情况下，问题是他们的更新站点提供的URL是:

https://cucumber.io/cucumber-eclipse/update-site

然而，当通过浏览器导航到它时，它重定向到(注意添加的“。github”):

http://cucumber.github.io/cucumber-eclipse/update-site/

因此，解决方案是在eclipse中添加更新站点时，只需使用更新站点URL的重定向版本。
