https握手異常與jdk版本異常
- 1.Received fatal alert: handshake_failure
- 2.Unsupported major.minor version XXX
1.Received fatal alert: handshake_failure
描述：
javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

at org.jsoup.helper.HttpConnection.get(HttpConnection.java:170) 原因：
jdk的版本太低，或者jvm的版本太低，隻能發送ssl1的請求，但是響應的是ssl2或者更高版本的響應，導緻ssl握手失敗。
解決方案：
增加jdk的版本（最簡單），如果非要用低版本，網上也有解決的方案。
步驟：（eclipse）
右鍵->build path->configure build path
Add Library
next
或者不用選擇：
不删除也可以
但有可能引起混亂
2.Unsupported major.minor version XXX
原因：編譯jdk版本與運作的jdk版本不一緻
右鍵->build path->configure build path
