Question

我现在有问题。我正在通过Azure使用Clear db。我无法将UTF8字符存储到表中。我正在使用Spring + Hibernate + Mysql组合。

我可以通过更新my.cnf文件来使其在本地工作，但是在Azure上它不允许我更新，因为我正在使用社区版并且被许多用户使用。他们建议遵循以下几点。但是我不知道如何在休眠配置中设置它

每次打开数据库连接时，在执行任何查询或要在该连接上运行的查询之前，应使用https://dev.mysql.com/doc/refman/5.5/en/set-names.html中说明的语法发出SET NAMES查询。因此，例如，设置所需的字符集和排序规则，可以使用

SET NAMES utf8 COLLATE utf8_bin;

下面给出了我的休眠文件

@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;
}

@Bean

    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;
}

/**

    HibernateTransactionManager txManager = new HibernateTransactionManager();
    txManager.setDataSource(this.jndiDataSource());
    txManager.setSessionFactory(this.sessionFactory().getObject());
    return txManager;
}
}

如何在休眠查询中发布SET NAMES
