尝试使用Spring Boot连接到MySQL数据库时，我得到以下stacktrace：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

这是我的配置：

application.properties：

spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost/app
spring.datasource.username=root
spring.datasource.password=password

spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=update

AppStarter.java：

@SpringBootApplication
public class AppStarter {

    public static void main(String[] args) {
        SpringApplication.run(AppStarter.class, args);
    }

}

ApplicationContextConfig.java：

@Configuration
public class ApplicationContextConfig {

    @Bean
    public HibernateJpaSessionFactoryBean sessionFactory(EntityManagerFactory emf) {
        HibernateJpaSessionFactoryBean factory = new HibernateJpaSessionFactoryBean();
        factory.setEntityManagerFactory(emf);
        return factory;
    }

}

的pom.xml：

我在这里尝试了所有类似问题的解决方案，但似乎都没有。

3 个答案:

答案 0 :(得分：1)

您需要提供端口以及服务器IP。

其他参数，如autoReconnect＆amp; useSSL是可选的。

您可以使用以下连接字符串

  

JDBC：MySQL的：//本地主机：3307 /应用

答案 1 :(得分：0)

我发现连接字符串搞砸了。将连接字符串更改为jdbc:mysql://localhost:3307/app?autoReconnect=true&useSSL=false修复了问题

答案 2 :(得分：0)

我有类似的问题。以下声明（仅在sudo mysql -p之后）不起作用：

mysql> create user 'user1'@'localhost' identified by '********';

还要补充：

mysql> create user 'user1'@'127.0.0.1' identified by '********';

可选择考虑执行此操作：

mysql> grant all privileges on thisdb.* to 'user1'@'127.0.0.1' identified by '*********';

然后它奏效了。
