网上找了一圈，发现是JDK版本的问题，原先的版本如下
C:\Users\Administrator>java -version
java version "1.8.0"
Java(TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode)
升级版本后，解决问题（升级到jdk8 131或者151均可）
C:\Users\Administrator>java -version
java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
