博客内容讲述了在Java中遇到`SSLContextImpl is not initialized`异常的场景。初始代码尝试初始化SSLContext但失败，导致异常。解决方法是使用SSLContextBuilder并自定义TrustStrategy，允许所有证书。修改后的代码成功创建了SSLConnectionSocketFactory，支持TLSv1.1到TLSv1.2。

刚开始的代码如下：

SSLContext sslContext = SSLContext.getInstance("SSL");

SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext,
      new String[] {"TLSv1"}, null,SSLConnectionSocketFactory.getDefaultHostnameVerifier());

执行后异常：

java.lang.IllegalStateException: SSLContextImpl is not initialized

at sun.security.ssl.SSLContextImpl.engineGetSocketFactory(SSLContextImpl.java:172)

at javax.net.ssl.SSLContext.getSocketFactory(SSLContext.java:294)

at org.apache.http.conn.ssl.SSLConnectionSocketFactory.<init>(SSLConnectionSocketFactory.java:275)

解决办法如下：

SSLContextBuilder sslContextBuilder = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {
   public boolean isTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
      return true;
   }
});
SSLContext sslContext =sslContextBuilder.build();

SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext,
      new String[]{"TLSv1.1", "SSLv3", "TLSv1", "TLSv1.2"},
      null, NoopHostnameVerifier.INSTANCE);
