“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

在花了好几个小时试图构建证书文件以使我的Java 6安装能够与新的twitter证书一起工作之后，我终于无意中发现了一个隐藏在留言板上的评论中令人难以置信的简单解决方案。只需从Java 7安装中复制cacerts文件，并覆盖Java 6安装中的cacerts文件。可能最好先备份cacerts文件，但随后只需复制新文件，然后嘣!它就是有用。

注意，我实际上复制了一个Windows cacerts文件到Linux安装中，它工作得很好。

该文件位于旧的和新的Java jdk安装中的jre/lib/security/cacerts中。

希望这能帮别人省下几个小时的麻烦。

其他回答

对我来说，证书错误弹出是因为我有fiddler运行在后台，这打乱了证书。它作为一个代理如此接近，并重新启动eclipse。

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

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。

如果您的存储库URL也可以在HTTP上工作，并且安全性不是问题，您可以访问settings.xml(通常，但不总是，位于%USERPROFILE%/.m2)，并将<repository>和<pluginRepository> URL的HTTPS替换为HTTP。

例如，这个:

<repository>
    <snapshots>
        <enabled>false</enabled>
    </snapshots>
    <id>central</id>
    <name>libs-release</name>
    <url>https://<artifactory>/libs-release</url>
</repository>

应改为:

<repository>
    <snapshots>
        <enabled>false</enabled>
    </snapshots>
    <id>central</id>
    <name>libs-release</name>
    <url>https://<artifactory>/libs-release</url>
</repository>
