Answer 1

Inject dataSourceProperties , and use determineUrl :

import org.springframework.boot.autoconfigure.jdbc.DataSourceProperties;

...


@Autowired
DataSourceProperties dataSourceProperties;

You can then call:

String dbUrl = dataSourceProperties.determineUrl();

Answer 2

you can used Properties:

package java.util.Properties

Properties springProperties = new Properties();
springProperties.getProperty("spring.datasource.url");
