Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
    If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

我们需要在配置类中为DataSource添加一个bean

@Bean
public DataSource dataSource(){
    DriverManagerDataSource source = new DriverManagerDataSource();
    source.setDriverClassName(driverClass);
    source.setUrl(url);
    source.setUsername(username);
    source.setPassword(password);
    return source;
}
