Wed Jan 23 13:51:50 CST 2019 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification. 2019-01-23 13:51:50.660 ERROR 5596 --- [Create-79791382] com.alibaba.druid.pool.DruidDataSource : create connection SQLException, url: jdbc:mysql://localhost:3306/renren_fast?allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8, errorCode 0, state 08001 com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at com.mysql.jdbc.Util.handleNewInstance(Util.java:404) at com.mysql.jdbc.Util.getInstance(Util.java:387) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:917) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:896) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:885) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:860) at com.mysql.jdbc.ConnectionImpl.connectOneTryOnly(ConnectionImpl.java:2332) at com.mysql.jdbc.ConnectionImpl.createNewIO(ConnectionImpl.java:2085) at com.mysql.jdbc.ConnectionImpl.<init>(ConnectionImpl.java:795) at com.mysql.jdbc.JDBC4Connection.<init>(JDBC4Connection.java:44) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at com.mysql.jdbc.Util.handleNewInstance(Util.java:404) at com.mysql.jdbc.ConnectionImpl.getInstance(ConnectionImpl.java:400) at com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:327) at com.alibaba.druid.filter.FilterChainImpl.connection_connect(FilterChainImpl.java:156) at com.alibaba.druid.filter.stat.StatFilter.connection_connect(StatFilter.java:218) at com.alibaba.druid.filter.FilterChainImpl.connection_connect(FilterChainImpl.java:150) at com.alibaba.druid.pool.DruidAbstractDataSource.createPhysicalConnection(DruidAbstractDataSource.java:1560) at com.alibaba.druid.pool.DruidAbstractDataSource.createPhysicalConnection(DruidAbstractDataSource.java:1623) at com.alibaba.druid.pool.DruidDataSource$CreateConnectionThread.run(DruidDataSource.java:2468) Caused by: java.lang.NullPointerException: null at com.mysql.jdbc.ConnectionImpl.getServerCharset(ConnectionImpl.java:3005) at com.mysql.jdbc.MysqlIO.sendConnectionAttributes(MysqlIO.java:1916) at com.mysql.jdbc.MysqlIO.proceedHandshakeWithPluggableAuthentication(MysqlIO.java:1845) at com.mysql.jdbc.MysqlIO.doHandshake(MysqlIO.java:1215) at com.mysql.jdbc.ConnectionImpl.coreConnect(ConnectionImpl.java:2255) at com.mysql.jdbc.ConnectionImpl.connectOneTryOnly(ConnectionImpl.java:2286) ... 16 common frames omitted
