Java 连接到url时未对对等方进行身份验证

请原谅我的无知，我真的不知道我在做什么，因为这是我的第一个网络程序。我知道我试图访问的服务器不需要验证，因为有人帮我编辑了web.xml文件，删除了身份验证过滤器。但是，当尝试连接到url时，我收到以下错误：

Exception in thread "main" javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

如果你有什么想法，请把它们传给我。资料来源如下：

远程主机的SSL证书无法使用Java客户端可用的CA证书向已知CA根验证。如果远程主机使用自签名证书，则需要将专用CA证书添加到Java客户端的密钥库中。如果是商业证书，请将相应的根CA证书添加到密钥库
