No appropritate connection provider encountered, assuming application will be supplying connections.?

是不是沒(méi)連上MySql數(shù)據(jù)庫(kù)？我在Navicat里已經(jīng)新建有數(shù)據(jù)庫(kù)了。或者是

或者是

<property name="connection.driver_class">com.mysql.jdbc.Driver</property>

然而我不清楚是否安裝了com.mysql.jdbc.Driver

對(duì)應(yīng)的mysql-connector-java-5.1.6-bin.jar已經(jīng)導(dǎo)入了……
