原因：
jdk的版本太低，或者jvm的版本太低，只能发送ssl1的请求，但是响应的是ssl2或者更高版本的响应，导致ssl握手失败。
解决方案：
增加jdk的版本（最简单），如果非要用低版本，网上也有解决的方案。
步骤：（eclipse）
右键->build path->configure build path
Add Library
next
或者不用选择：
不删除也可以
但有可能引起混乱
2.Unsupported major.minor version XXX
原因：编译jdk版本与运行的jdk版本不一致
右键->build path->configure build path
然后一直确定就可以，最后会重新编译项目。
