Java SSLException:握手失败

我正在开发一个SpringBootAPI，它应该与SSL端点（即https端点）通信。我已配置密钥库，请将其放在我的资源文件夹下。我已经从https端点下载了证书，并将其添加到我的jdk信任库文件（即cacerts）中。我还创建了一个配置类，如下所示：

@Configuration
public class ConnectorConfig {
    @Bean
    public TomcatServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
            @Override
            protected void postProcessContext(Context context) {
                SecurityConstraint securityConstraint = new SecurityConstraint();
                securityConstraint.setUserConstraint("CONFIDENTIAL");
                SecurityCollection collection = new SecurityCollection();
                collection.addPattern("/*");
                securityConstraint.addCollection(collection);
                context.addConstraint(securityConstraint);
            }
        };
        tomcat.addAdditionalTomcatConnectors(getHttpConnector());
        return tomcat;
    }

    private Connector getHttpConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        connector.setPort(8080);
        connector.setSecure(false);
        connector.setRedirectPort(8443);
        return connector;
    }
}

我调用https端点的API如下所示：

public String sendPost(String targetURL, String urlParameters) {
        
 

   URL url;
    HttpsURLConnection connection = null;
    try {
    
    //disableSslVerification();
    //Create connection
    url = new URL(targetURL);
    connection = (HttpsURLConnection) url.openConnection();
    HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> true);
    connection.setRequestMethod("POST");
    connection.setRequestProperty("Content-Type",
            "text/xml");
    
    connection.setRequestProperty("Content-Length", "" +
            Integer.toString(urlParameters.getBytes().length));
    connection.setRequestProperty("Content-Language", "en-US");

    connection.setUseCaches(false);
    connection.setDoInput(true);
    connection.setDoOutput(true);

    //Send request
    DataOutputStream wr = new DataOutputStream(
            connection.getOutputStream());
    wr.writeBytes(urlParameters);
    wr.flush();
    wr.close();

    //Get Response
    InputStream is = connection.getInputStream();
    BufferedReader rd = new BufferedReader(new InputStreamReader(is));
    String line;
    StringBuffer response = new StringBuffer();
    while ((line = rd.readLine()) != null) {
        response.append(line);
        response.append('\r');
    }
    rd.close();
    return response.toString();

} catch (Exception e) {

    e.printStackTrace();
    return null;

} finally {

    if (connection != null) {
        connection.disconnect();
    }
}
}

我收到的错误如下：

任何对正确方向的帮助都将非常有用

您的代码仅显示8080端口上的普通HTTP连接器。不清楚您使用的是什么

targetURL

，但是如果您尝试

https://...:8080

然后它将失败，因为端口8080上没有配置HTTPS。
