我现在有个问题。我正在通过azure使用clear db。我无法将utf8字符存储到表中。我使用的是spring+hibernate+mysql组合。
我可以通过更新 my.cnf 但在azure上它不允许我更新,因为我使用的是communityedition,并且被许多用户使用。他们建议遵循下面的观点。但是我不知道如何在hibernate配置上设置它
每次打开到数据库的连接时,在执行要在该连接上运行的任何查询之前,应使用中解释的语法发出set names查询https://dev.mysql.com/doc/refman/5.5/en/set-names.html. 例如,要设置所需的字符集和排序规则,可以使用

SET NAMES utf8 COLLATE utf8_bin;

我的休眠文件如下

@Configuration
@EnableTransactionManagement
public class HibernateConfig {

/**
 * Uses an datasource library for local testing with out creating datasources on the server. Not to be used for Production.
 *
 * @return
 */
@Bean
public DriverManagerDataSource jndiDataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    try {
        DriverManager.registerDriver(new com.mysql.jdbc.Driver());
    } catch (SQLException e) {
        e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
    }
    dataSource.setDriverClassName("com.mysql.jdbc.Driver");

    dataSource.setUrl("jdbc:mysql://<azureurl>-f.cloudapp.net:3306/db1");
    dataSource.setUsername("user");
    dataSource.setPassword("pw");

    return dataSource;
}

/**
 * Datasource to be used when running on App servers
 * @return
 * @throws javax.naming.NamingException
 */
/*public @Bean
DataSource jndiDataSource() throws NamingException{
    return (DataSource) new InitialContext().lookup(environment.getProperty("datasourceJndi"));
}

* /

/**

@Bean
public org.springframework.orm.hibernate4.LocalSessionFactoryBean sessionFactory() throws NamingException {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

    Properties prop = new Properties();
    prop.put("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
    //prop.put("hibernate.dialect", "org.hibernate.dialect.OracleDialect");
    //Be extremely careful before changing this value to Update or Create
    prop.put("hibernate.hbm2ddl.auto", "none");
    prop.put("hibernate.show_sql", "false");
    prop.put("hibernate.enable_lazy_load_no_trans","true");
    prop.put("hibernate.connection.CharSet","utf8");
    prop.put("hibernate.connection.characterEncoding","utf8");
    prop.put("hibernate.connection.useUnicode",true);

    sessionFactory.setDataSource(this.jndiDataSource());
    sessionFactory.setPackagesToScan(new String[]{"com.sp.domain"});
    sessionFactory.setHibernateProperties(prop);
    return sessionFactory;
}

/**
 * @return
 * @throws javax.naming.NamingException
 */
@Bean
public HibernateTransactionManager transactionManager() throws NamingException {
    HibernateTransactionManager txManager = new HibernateTransactionManager();
    txManager.setDataSource(this.jndiDataSource());
    txManager.setSessionFactory(this.sessionFactory().getObject());
    return txManager;
}
}
