hibernate.cfg.xml加上属性. <property name="connection.useUnicode">true</property> <property name="connection.characterEncoding">UTF-8</property> mysql 的驱动用3.0.15以上版本的, 加个Filter, 使用UTF-8字符集就可以了, 若使用Spring则写在spring中的sessionFactory里即可。 例如： <?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <!-- Generated by MyEclipse Hibernate Tools. --> <hibernate-configuration> <session-factory> <property name="connection.username">root</property> <property name="connection.url"> jdbc:mysql://localhost:3306/hibernate_table </property> <property name="dialect"> org.hibernate.dialect.MySQLDialect </property> <property name="myeclipse.connection.profile"> mySql hibernatetable </property> <property name="connection.password">12345678</property> <property name="connection.driver_class"> com.mysql.jdbc.Driver </property> <property name="connection.useUnicode">true</property> <property name="connection.characterEncoding">UTF-8</property> <property name="show_sql">true</property> <property name="format_sql">true</property> <mapping resource="cn/com/hibernate/Demo/Guestbook.hbm.xml" /> <mapping resource="cn/com/hibernate/Demo/GMapping.hbm.xml" />
