How do I wire properties with Spring’s p namespace?

Beside using the <property> element, Spring framework also provide us another way to wiring value or reference into the bean. We can use the Spring’s p namespaces. The p namespace has a schema URI of

With this namespace declared in the Spring configuration file you can use the p: prefixed attribute of the <bean> element to wire bean’s property.

We update the configuration used in the previous example How do I inject into bean properties? to use the p namespace. Here is the new Spring’s configuration file.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=""

    <bean id="rectangle" class="org.kodejava.example.spring.inject.Rectangle"/>

    <bean id="drawingBean"
          p:colour="Red" p:shape-ref="rectangle"/>


The p:color attribute set the color property to Red, this is a simple value. To set the shape property we use the p:shape-ref attribute. The -ref suffix tell Spring that we are injecting a reference.

You can use the <property> element or using the p namespace to inject bean’s property. Both of them have the same functionality.
