The XML-based configuration has been the primary configuration technique since Spring started. In this section, we will see the same example as we discussed in the DI pattern, and see how the CustomerService object is injected in the BankingService class through an XML-based configuration.
For an XML-based configuration, we need to create an applicationContext.xml file with a <beans> element. The Spring container must be able to manage one or more beans in the application. Beans are described using the <bean> element inside a top-level <beans> element.
Following is the 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" ...
