今日测试Pentaho ，用的是MSSQL

Pentaho Kettle 连接MSSQL 数据库报错，数据库JDBC 驱动安装正确的情况下

报 ConectionServicelmpl.ERROR_0009-到数据库的连接失败。

分析下原因：

日志位置：/tomcat/logs

ERROR [org.pentaho.platform.dataaccess.datasource.wizard.service.impl.ConnectionServiceImpl] ::: ConnectFactory.ERROR_0001 – 无法与 com.microsoft.sqlserver.jdbc.SQLServerDriver jdbc:sqlserver://localhost:1433;databaseName=FANBI;integratedSecurity=false 建立数据库连接

分析是连接安全性的问题

正好它的数据连接里有个选项，配置 encrypt 值为 false 就可以通过测试了。
