今天在用maven工程连接数据库的时候报了这样一个错误。
条件：已在pom文件中添加mysql-connector-java-5.1.39.jar依赖依然无法解决
最后的解决方法：去掉依赖，自己去官网下载了mysql-connector-java-5.1.45-bin.jar包。
File-project structure-library-点+号，添加自己下载的jar包，竟然就不报错了。
部分代码：
try{
Class.forName("com.mysql.jdbc.Driver");
}catch(ClassNotFoundException e) {
System.out.println("Where is your mysql JDBC Driver? "
+"Include in your library path!");
e.printStackTrace();
logger.info("Where is your mysql JDBC Driver? "
+"Include in your library path!");
logger.info(USE.getTrace(e));
continue;
}
System.out.println("mysql JDBC Driver Registered!");
logger.info("mysql JDBC Driver Registered!");
Connection connection =null;
try{
connection = DriverManager.getConnection(
"jdbc:mysql://localhost:3306/Mytest?autoReconnect=true&useSSL=false",
"root","aa223183");
}catch(SQLException e) {
System.out.println("Connection Failed! Check output console");
e.printStackTrace();
logger.info("Connection Failed! Check output console");
logger.info(USE.getTrace(e));
continue;
/*
* try { Thread.sleep(1000*10); } catch (InterruptedException
* e1) { //TODO Auto-generated catch block* e1.printStackTrace(); }
*/
}
