服务器报错如下：
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption. Error: "SQL Server returned an incomplete response. The connection has been closed. ClientConnectionId:e8dd5a3f-2464-4d24-aca9-4c2785c34ff4".
解决方式：
jdk1.6.0_43\jre\lib\ext目录下加入bcprov-ext-jdk15on-1.54.jar、bcprov-jdk15on-1.54.jar两个jar包
jdk1.6.0_43\jre\lib\security 目录下修改java.security文件，修改security.provider.1=sun.security.provider.Sun
改为security.provider.1=org.bouncycastle.jce.provider.BouncyCastleProvider
