“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

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>

我为Intellij Idea解决了这个问题 虽然，我改变了很多地方来解决问题。我找到了一个解决方案。右键单击你的项目，你会看到Maven，然后按生成源代码和更新文件夹和重新导入

完成了。

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。

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。

解决方案

请记住，有许多可能的原因产生这个错误，在我的情况下，我用以下方式修复了它:

用Gradle文件同步项目 检查错误无法解决com。咕gle.firebase: firebase-crashlytics-gradle:魅惑。 结构变化。Gradle (:project) from comGoo gle.firebase:firebase-crashlytic -gradle:2.1.0 to com.google.firebase:firebase-crashlytic -gradle:2.1.0(注意空格)

依赖类路径中的任何错误都会生成这种类型的异常。检查生成问题的提交的gradle。

我留下一些小费。

使用- dsll .debug=true检查SSL。 检查您是否正在创建隧道或试图忽略它

SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, (x509CertChain, authType) -> true).build();
            httpClient = HttpClientBuilder.create()
                    .setSSLContext(sslContext)
                    .setConnectionManager(new PoolingHttpClientConnectionManager(RegistryBuilder.<ConnectionSocketFactory>create()
                            .register("http", PlainConnectionSocketFactory.INSTANCE)
                            .register("https", new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE))
                            .build()
                    )).build();

httpClient.execute(requisicao)
