SpringDependInjection.MD

1. Create applicationContext.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<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.xsd">

<bean autowire="byName" class="di.constructorInjection.User" id="user">
	<constructor-arg value="Buddha"/>
	<constructor-arg value="30"/>
	<constructor-arg value="Nepal"/>
	<constructor-arg>
		<list>
			<value>Kathmandu</value>
			<value>Dhangadi</value>
			<value>Mahendranagar</value>
		</list>
	</constructor-arg>
</bean>


<bean class="di.setterInjection.Address" id="address">
	<property name="city" value="KTM"/>
	<property name="state" value="BAGMATI"/>
	<property name="zip" value="0977"/>
	<property name="country" value="NEPAL"/>
</bean>

<bean class="di.setterInjection.UserDto" id="userSetterInjection">
	<property value="Buddha(Gautam)" name="name"/>
	<property value="30" name="age"/>
	<property name="address" ref="address"/>
</bean>

</beans>

Make sure you have spring-beans framework is also in pom.xml file.

<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-beans</artifactId>
			<version>${spring-framework.version}</version>
		</dependency>

Test it:

ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
// ====INJECTING THROUGH CONSTRUCTOR=======
User user = (User) context.getBean("user");
System.out.println(user);

// =========INJECTING THROUGH SETTER METHODS============
UserDto userDto = context.getBean("userSetterInjection", UserDto.class);
System.out.println(userDto);
