spring通过hibernate插入数据，mysql中文显示问号？

Question

该转码的都转了，请问还有关键的哪里没有转呢？？

userName=root
password=
driveClass=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/spring001?useUnicode=true&characterEncoding=UTF-8

这里转了

数据库也是utf-8啊

平常使用hibernate的时候，这样设置是没问题的。但是加上spring后，就不行了，出现中文显示问号

附上我的applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

已经解决。原来是url格式的问题：

如果url是写在hibernate.cfg.xml这样的xml文件中，需要在&后面加上：amp;

jdbc:mysql://localhost:3306/spring001?useUnicode=true&characterEncoding=UTF-8

如果在其他的则不用，如上，我自己写的db.properties文件则不需要加上
jdbc:mysql://localhost:3306/spring001?useUnicode=true&characterEncoding=UTF-8

Answer 2

在xml的配置文件中 “&”要用 “& ” 代替
