Example of XML based bean configuration

Finally, let's take a look at XML-based configuration. This is the traditional way of configuring beans in Spring.

Obviously, in this approach, we do all bean mappings in an XML configuration file.

So let's create an XML configuration file, account-bean-config.xml, and define beans for our AccountService class:

<?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 id="accountService" class="com.baeldung.applicationcontext.AccountService">
    <constructor-arg name="accountRepository" ref="accountRepository" />
  </bean>

  <bean id="accountRepository" class="com.baeldung.applicationcontext.AccountRepository" />
</beans>
