Concept Overview Spring’s P namespace is an alternative to using the property tag. By using p namespace, we can perform dependency injection by directly using the attribute of bean tag instead of using the property tag. The benefits of using p namespace are: p namespace is more compact than property tag Using p namespace reduces … Read more

Concept Overview Sometimes, it is necessary to inject a Collection of type java.util.Properties into a bean using Spring injection. e.g. A Car has many technical specifications associated with in the form of name-value pairs (e.g. Weight, Maximum Torque, No. of cylinders, etc). This is achieved by using the props tag within the property tag in … Read more
