JDBC和Hibernate连接MySQL中文乱码问题

    一般jdbc连接时只需要将url写成如下即可：
    jdbc:mysql://127.0.0.1:3306/hello?useUnicode=true&characterEncoding=UTF-8 

    但是在使用Hibernate时，这种写法会报错：

org.hibernate.HibernateException: Could not parse configuration: /hibernate.cfg.xml
at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:2075)
at org.hibernate.cfg.Configuration.configure(Configuration.java:1987)

    于是去网上找，发现&要使用转义字符，所以在hibernate.cfg.xml中正确的配置应该是：

<property name="connection.url">
jdbc:mysql://127.0.0.1:3306/hello?useUnicode=true&characterEncoding=UTF-8
</property>
