因此对于 Java 8，您需要做的就是以下内容.

import javax.net.ssl.*;导入 java.net.URL;URL url = new URL("https://www.google.com");HttpsURLConnection 连接 = (HttpsURLConnection) url.openConnection();

Java 7

Java 7 需要手动设置

import java.security.*;导入 javax.net.ssl.*;导入 java.net.URL;URL url = new URL("https://www.google.com");SSLContext ssl = SSLContext.getInstance("TLSv1.2");ssl.init(null, null, new SecureRandom());HttpsURLConnection 连接 = (HttpsURLConnection) url.openConnection();connection.setSSLSocketFactory(ssl.getSocketFactory());

How to connect to TLS 1.2 enabled URL using HTTP POST Method.

解决方案

Java 8

https://blogs.oracle.com/java-platform-group/jdk-8-will-use-tls-12-as-default

So for Java 8 all you need to do is the following.

import javax.net.ssl.*;
import java.net.URL;

URL url = new URL("https://www.google.com");
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();

Java 7

import java.security.*;
import javax.net.ssl.*;
import java.net.URL;


URL url = new URL("https://www.google.com");

SSLContext ssl = SSLContext.getInstance("TLSv1.2");
ssl.init(null, null, new SecureRandom());

HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setSSLSocketFactory(ssl.getSocketFactory());
