Question

我在SpringBoot中使用MyAql数据库使用JPA创建了一个Rest完整Web服务，我的Web服务在localhost上使用Windows机器正常工作。但是当我在Linux上使用它时，它成功部署并在Linux服务器上的远程数据库上自动创建表。但在此之后，当为select或insert查询调用web服务时，它会引发异常。

我的连接代码是

@Bean
public DataSource getDataSource() {
    BasicDataSource dataSource = new BasicDataSource();
    dataSource.setDriverClassName("com.mysql.jdbc.Driver");
    dataSource.setUrl("jdbc:mysql://serverip:3306/MARK7");
    dataSource.setUsername("abcd123");
    dataSource.setPassword("abcd123");
    return dataSource;
}

例外：

在你的日志中我可以看到这个例外：

那么，你指的是正确的架构吗？或者你没有创建这个表。
