Answer 1

Try adding the mysql-connector jar to the classpath when you execute your command-line code:

java -cp mysql-connector-java-5.1.20-bin.jar;. jdbc11

Answer 2

You have to add -classpath in the execute command

java -classpath mysql-connector-java-5.1.20-bin.jar jdbc11

Answer 3

如果我理解你就好了，你缺少的是java命令行中的-cp选项，如果你把它放在构建路径中，这就是eclispe在内部做的事情。
