What does the error message "url" attribute not specified in Pom.xml spring-security-web mean when configuring a DataSource?

edit

The error message "url" attribute not specified in Pom.xml spring-security-web means that the URL attribute is not defined or specified in the Pom.xml file for the Spring security web application. This is typically required when configuring a DataSource for the application. The URL attribute is necessary to specify the location of the database that the application will use for data storage and retrieval. Without this attribute, the application will not be able to connect to the database and will not be functional.
