这个错误通常是由于 SSL 证书问题引起的。可能是因为您的 Java 运行时环境没有正确配置 SSL 证书,或者您正在尝试连接到一个使用自签名证书的 HTTPS 站点。您可以尝试以下解决方法:
1. 更新您的 Java 运行时环境,确保它包含最新的根证书。
2. 如果您正在连接到一个使用自签名证书的 HTTPS 站点,请尝试将该证书导入到您的 Java 运行时环境中。
3. 如果您使用的是 Apache HttpClient,请确保您已经正确地配置了 SSL 上下文。

unable to find valid certification path to requested target
The error "unable to find valid certification path to requested target" usually occurs when a Java application is unable to establish a secure connection with a remote server due to missing or invalid SSL certificates.
To resolve this issue, you can try the following steps:
1. Update the Java Runtime Environment (JRE) to the latest version. Sometimes, older versions may have issues with SSL certificates.
2. Import the SSL certificate of the remote server into the JRE's truststore. You can use the keytool command-line tool to import the certificate. Here is an example command:
```
keytool -import -alias mycert -keystore cacerts -file <path-to-certificate-file>
```
Replace `<path-to-certificate-file>` with the actual path to the certificate file. The default password for the truststore is usually "changeit".
3. If you are running the application in an IDE, make sure that the IDE is using the same JRE and truststore that you have modified.
By following these steps, you should be able to resolve the "unable to find valid certification path to requested target" error.
idea unable to find valid certification path to requested target
"unable to find valid certification path to requested target" 是一个常见的错误信息,通常在使用IDEA进行Maven构建时出现。这个错误是由于Maven无法验证目标站点的证书而导致的。解决这个问题的方法有几种。
一种常用的方法是下载目标站点的证书,并将其导入到Java密钥库中。然后,在运行IDEA时,通过设置JVM选项"-Djavax.net.ssl.trustStore=..."来使用该密钥库。这样IDEA就可以信任目标站点的证书了。
另一种解决方法是使用阿里云的Maven镜像源,这个镜像源已经配置好了相应的证书。只需要在Maven的配置文件中将镜像源设置为"https://maven.aliyun.com/repository/central"即可。
总结起来,解决"unable to find valid certification path to requested target"错误的方法有两种:一是下载站点证书并导入密钥库,二是使用阿里云的Maven镜像源。具体选择哪种方法取决于个人的需求和偏好。
