Here the below code will show you how to inject the Properties in Spring using the spring.xml file. By using that we will inject the Properties Class object in spring.

Customer.java

package com.evon;
import java.util.Properties;

public class Customer {


    private Properties prop;


    public Properties getProp() {
        return prop;
    }

    public void setProp(Properties prop) {
        this.prop = prop;
    }

}

spring.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">


    <bean id="customer" class="com.evon.Customer">

        <!-- java.util.Properties -->
         <property name="prop">
            <props>
                <prop key="email">manish@evontech.com</prop>
                <prop key="desig">Developer</prop>
            </props>
        </property> 

    </bean>

</beans>

App.java

package com.evon;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App {
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext(
                "spring.xml");

        Customer cust = (Customer) context.getBean("customer");
        System.out.println(cust.getProp());
    }
}
