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)

Caused by: org.dom4j.DocumentException: Error on line 9 of document  : The reference to entity "characterEncoding" must end with the ';' delimiter.  Nested exception: The reference to entity "characterEncoding" must end with the ';' delimiter.

    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：

jdbc:mysql://127.0.0.1:3306/hello?useUnicode=true &characterEncoding=UTF-8
