我的HibernateConfiguration.java 文件是：

@Configuration
@EnableTransactionManagement
@ComponentScan( "b.c.m.h.configuration" )
@PropertySource(value =  "classpath:application.properties" )
public class HibernateConfiguration 

@Autowired
private Environment environment;

@Bean
public LocalSessionFactoryBean sessionFactory() 
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
    sessionFactory.setDataSource(dataSource());
    sessionFactory.setPackagesToScan(new String[]  "b.c.m.h.model" );
    sessionFactory.setHibernateProperties(hibernateProperties());
    return sessionFactory;


@Bean
public DataSource dataSource() 
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
    dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
    dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
    dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
    return dataSource;


private Properties hibernateProperties() 
    Properties properties = new Properties();
    properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
    properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
    properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
    properties.put("hibernate.hbm2ddl.auto", environment.getRequiredProperty("hibernate.hbm2ddl.auto"));
    properties.put("hibernate.connection.driver-class", "com.mysql.jdbc.Driver");
    return properties;        


@Bean
@Autowired
public HibernateTransactionManager transactionManager(SessionFactory s) 
    HibernateTransactionManager txManager = new HibernateTransactionManager();
    txManager.setSessionFactory(s);
    return txManager;

而application.properties 是：

jdbc.driverClassName= com.mysql.jdbc.Driver
jdbc.url= jdbc:mysql://localhost:3306/hrm?createDatabaseIfNotExist=true
jdbc.username= user
jdbc.password= password
hibernate.dialect= org.hibernate.dialect.MySQL5Dialect
hibernate.show_sql= true 
hibernate.format_sql= true
hibernate.hbm2ddl.auto=update

我在这里错过了什么？

【问题讨论】：

【参考方案1】：

如果您尝试连接到服务器上的 mariadb

添加以下依赖

<dependency>
    <groupId>org.mariadb.jdbc</groupId>
    <artifactId>mariadb-java-client</artifactId>
    <version>xxx</version>
</dependency>

并更新您的application.properties 属性

jdbc.driverClassName=org.mariadb.jdbc.Driver
jdbc.url=jdbc:mariadb://localhost:3306/hrm?createDatabaseIfNotExist=true
hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect

PS : 删除application.properties 中= 之后的任何多余空格

验证 mariadb 服务器是否在您尝试部署应用程序的同一台服务器上运行。

您可以参考：http://sterl.org/2015/09/spring-boot-mariadb/
