在testcontainers的init函数中获取数据源属性

import org.testcontainers.containers.PostgreSQLContainer;
import org.testcontainers.utility.DockerImageName;

public class MyDatabaseContainer extends PostgreSQLContainer<MyDatabaseContainer> {

    private static final DockerImageName IMAGE_NAME = DockerImageName.parse("postgres:13");

    public MyDatabaseContainer() {
        super(IMAGE_NAME);
    }

    public void init() {
        this.start(); // 启动容器

        // 获取数据库连接URL
        String jdbcUrl = this.getJdbcUrl();
        System.out.println("JDBC URL: " + jdbcUrl);

        // 获取用户名和密码
        String username = this.getUsername();
        String password = this.getPassword();
        System.out.println("Username: " + username);
        System.out.println("Password: " + password);
    }
}
