http://www.xianlaiwan.cn/learn/767: 如果是用IDEA+maven的話，換國內的源，然后run，不然會提示“Exception in thread "main" java.lang.NoClassDefFoundError”是jar包沒有下載成功。例如用IDEA自帶的maven的時候，改一下maven源的配置：JetBrains\IntelliJ IDEA 2017.2.5\plugins\maven\lib\maven3\conf\settings.xml：加上阿里云的源。http://www.cnblogs.com/phpdragon/p/7216626.html
