Does Spring boot require XML configuration to function?

Spring Boot takes an opinionated view of the Spring platform and third-party libraries, allowing us to get started with a minimal configuration. For example we can develop a Jave EE based web application without any configuration files. xml file is required!

Why we use XML in Spring?

I would say that the reason Spring favors XML over Java is that the two languages are for two different tasks. Java is a programming language. Its purpose is to describe algorithms, programs, control flow, etc. If deducing the structure of your program requires complex control flow, Java would be a good choice.

Why we use XML file in spring?

Is it possible to have multiple configuration files in spring?

You may load multiple Spring bean configuration files in the code : ApplicationContext context = new ClassPathXmlApplicationContext(new String[] {“Spring-Common. xml”, “Spring-Connection. Put all spring xml files under project classpath.

Which annotation allows loading of beans without XML configuration?

spring bean
No single xml line is written to achieve our so called spring bean definition inside container. Note: we can write ‘n’ no of methods inside single configuration class to define multiple beans but all methods should be annotated with @Bean.

Spring 3 provides the ability to use a Java based configuration file, as opposed to using those monolithic XML configuration files that everyone hates.

How do I import a Java configuration file into spring 3?

It’s as easy as a little import annotation at the top of your config file. Spring 3 provides the ability to use a Java based configuration file, as opposed to using those monolithic XML configuration files that everyone hates. However, it doesn’t have to be a complete “annotations vs. xml” debate, as you can easily combine both approaches.

How do I compare spring with and without XML?

To compare Spring with and Spring without XML, I’m going to create a runnable class named SumRunner that goes through the steps of obtaining an instance of the GameSummary bean, both by using XML, and also by using Spring without XML. Here’s how the SumRunner looks.

Does sumrunner generate the same Bean as the annotation configuration?

When you actually run the SumRunner class, you will obtain the following output, demonstrating that both the Spring XML configuration, and Spring annotation configuration, generated exactly the same bean:
