Spring引导服务器&x2B；java客户端

我想在Spring引导服务器和JavaFx客户端之间创建HTTPS连接。你能帮我吗

下面是我的示例：（这是我的控制器类）

我创建了一个这样的密钥->

keytool.exe" -genkey -alias springboot -storetype PKCS12 -keyalg RSA -keyalg RSA -keysize 2048 -keystore mykeystore.12 -validity 3650

在设置application.properties后，如下所示：

server.port=8443
server.ssl.key-store=mykeystore.p12
server.ssl.key-store-password=changeit
server.ssl.key-store-type=PKCS12
server.ssl.key-alias=springboot

现在服务器工作了。但我无法从java客户端发送HTTPS请求

package com.company;

import javax.net.ssl.HttpsURLConnection;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;

public class Main {

    private static final String USER_AGENT = "Mozilla/5.0";

    public static void main(String[] args) {
        try {
            sendGet();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static void sendGet() throws Exception {

        String url = "https://localhost:8443/";

        URL obj = new URL(url);
        HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();

        // optional default is GET
        con.setRequestMethod("GET");

        //add request header
        con.setRequestProperty("User-Agent", USER_AGENT);

        int responseCode = con.getResponseCode();
        System.out.println("\nSending 'GET' request to URL : " + url);
        System.out.println("Response Code : " + responseCode);

        BufferedReader in = new BufferedReader(
                new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuffer response = new StringBuffer();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        //print result
        System.out.println(response.toString());

    }

}

我尝试了此解决方案：但无法工作。

您的客户端不信任服务器的自签名证书。出于测试目的，您需要：

将证书作为受信任的CA导入JKS信任库，并配置客户端以使用它。

javax.net.ssl.trustStore

属性是最简单的方法

禁用客户端上的所有SSL信任检查

这两种方法都是有效的。禁用信任检查时请注意警告。

“但它无法工作”=>为什么？这正是你要做的。。。

package com.company;

import javax.net.ssl.HttpsURLConnection;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;

public class Main {

    private static final String USER_AGENT = "Mozilla/5.0";

    public static void main(String[] args) {
        try {
            sendGet();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static void sendGet() throws Exception {

        String url = "https://localhost:8443/";

        URL obj = new URL(url);
        HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();

        // optional default is GET
        con.setRequestMethod("GET");

        //add request header
        con.setRequestProperty("User-Agent", USER_AGENT);

        int responseCode = con.getResponseCode();
        System.out.println("\nSending 'GET' request to URL : " + url);
        System.out.println("Response Code : " + responseCode);

        BufferedReader in = new BufferedReader(
                new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuffer response = new StringBuffer();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        //print result
        System.out.println(response.toString());

    }
