## 问题背景
在某个项目中,测试环境调用对方https接口报javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure 异常,使用postman等工具调用对方接口可以返回数据,那就是我们这边的问题,第一件事是看有没有导入证书,发现确实导入了证书后还是调用失败,第二步来进行分析了对方接口的协议([查询接口支持协议](https://myssl.com/)),但是jdk1.6的不支持TLS1.2,1.1,导致无法请求成功
[stackoverflow问题类似情况](https://stackoverflow.com/questions/6353849/received-fatal-alert-handshake-failure-through-sslhandshakeexception)
[jdk使用jdk.tls.client.protocols](https://www.java.com/en/configure_crypto.html#enableTLSv1_2)(当时没有试这里面的方法,用其他方法解决了)
1.在测试环境中切换jdk为1.7,并且忽略SSL验证后可解决,但是这个项目太老了,不敢升级jdk,只能找其他办法
2.从官网下载jce安装包,[jce下载地址](https://www.oracle.com/technetwork/java/javase/downloads/jce-all-download-5170447.html),下载后替换到测试环境,was环境下的服务访问数据库失败,导致无法使用,所以此方法不行
3.在访问求前增加这段代码
```java
System.setProperty("https.protocols", "TLSv1.2,TLSv1.1,SSLv3");
```
此方法发现还是不行
4.使用第三方jar包bcprov-jdk15on,先引入,
```xml
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15on</artifactId>
<version>1.55</version>
</dependency>
```
然后修改如下请求代码
新增类TLSSocketConnectionFactory,修改请求方式,解决问题!
