Question

我正在尝试使用 Java 查找此页面的内容。

https://wordassociations.net/en/words-associated-with/cessation?button=Search

但是，我收到以下错误。我该如何解决它

Exception in thread "main" javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

/*
 * SynonymFinder.java
 * 
 */    
import java.net.URL;
import java.util.Scanner;

public class SynonymFinder {

    public static void main(String[] args) throws Exception {
        SynonymFinder obj = new SynonymFinder();

        System.out.println(get("https://wordassociations.net/en/words-associated-with/cessation?button=Search"));
    }

    public static String get(String url) throws Exception {
        StringBuilder sb = new StringBuilder();
        for(Scanner sc = new Scanner(new URL(url).openStream()); sc.hasNext(); )
           sb.append(sc.nextLine()).append('\n');
        return sb.toString();
     }
}
