做hibernate練習(xí)的時(shí)候報(bào)這個(gè)錯(cuò)誤，org.hibernate.MappingException: Unknown entity: Students。找了很久，網(wǎng)上都是說原因是沒有在cfg.xml文件中配置Mapping,但是我也配置了的。這是我的配置：? ? <property name="connection.username">root</property>? ? <property name="connection.password"></property>? ? <property name="connection.driver_class">com.mysql.jdbc.Driver</property>? ? <property name="connection.url">jdbc:mysql:///hibernate?useUnicode=true&amp;characterEncoding=UTF-8</property>? ? <property name="dialect">org.hibernate.dialect.MySQLDialect</property>? ? ? ? <property name="show_sql">true</property>? ? <property name="format_sql">true</property>? ? <property name="hbm2ddl.auto">create</property>? ? ? ? <mapping resource="Students.hbm.xml"/>請(qǐng)大神幫我看看哪里出錯(cuò)了??！感激不盡
