sunjce_provider-1.0.0.jar下载

本地启动jar包 启动会报错：nested exception is com.microsoft.sqlserver.jdbc.SQLServerException: The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption. Error: "RSA premaster secret error" 所以需要导入一个包： Solving the problem was a matter of putting the sunjce_provider.jar in one of the folders specified in the java.ext.dirs parameter. Hard to find, easy to solve. 把sunjce_provider.jar 放到JDKclasspath路径下
