YAML is a data serialization language that is often used for writing configuration files. So YAML configuration file in Spring Boot provides a very convenient syntax for storing logging configurations in a hierarchical format. The application. properties file is not that readable.
Indeed, What are Microservices in Spring Boot?
What are microservices? Microservices are a modern approach to software whereby application code is delivered in small, manageable pieces, independent of others.
Then, What is yml vs YAML? YAML – yaml vs yml file
Yaml files created with yaml and yml file extension, Both are the same in interpretation and syntax. Nowadays, there is no OS system level enforcement to have 3 letters in extensions. Most of the yaml users are using . yaml as their preferred choice.
What is lazy loading in spring boot? @Lazy annotation indicates whether a bean is to be lazily initialized. It can be used on @Component and @Bean definitions. A @Lazy bean is not initialized until referenced by another bean or explicitly retrieved from BeanFactory . Beans that are not annotated with @Lazy are initialized eagerly.
In the same way What is the use of @SpringBootApplication? Spring Boot @SpringBootApplication annotation is used to mark a configuration class that declares one or more @Bean methods and also triggers auto-configuration and component scanning. It’s same as declaring a class with @Configuration, @EnableAutoConfiguration and @ComponentScan annotations.
Is REST API a microservice?
REST is a valuable architectural style for microservices, thanks to its simplicity, flexibility, and scalability. One of the strongest advantages of REST for microservices is that services can communicate without requiring internal knowledge of one another.
What is MVC in spring?
The Spring Web MVC framework provides Model-View-Controller (MVC) architecture and ready components that can be used to develop flexible and loosely coupled web applications.
What is difference between REST API and microservices?
Microservices: The individual services and functions – or building blocks – that form a larger microservices-based application. RESTful APIs: The rules, routines, commands, and protocols – or the glue – that integrates the individual microservices, so they function as a single application.
What is YAML syntax?
YAML syntax
YAML has features that come from Perl, C, XML, HTML, and other programming languages. YAML is also a superset of JSON, so JSON files are valid in YAML. YAML uses Python-style indentation to indicate nesting. Tab characters are not allowed, so whitespaces are used instead.
What is JSON and YAML?
JSON and YAML are two popular formats for data exchange between different applications and languages, also known as data serialization. They’re similar in function and features: they represent data objects and structures and use a simple syntax that facilitates readability and editability.
Why is YAML better than properties?
YAML files are more clear and human-readable in comparison to properties files and also provide several unique and useful feature for us. YAML supports Maps, lists, and scalar types.
What is @component annotation in Spring boot?
@Component is an annotation that allows Spring to automatically detect our custom beans. In other words, without having to write any explicit code, Spring will: Scan our application for classes annotated with @Component. Instantiate them and inject any specified dependencies into them. Inject them wherever needed.
What is singleton scope in Spring?
singleton. Scopes a single bean definition to a single object instance per Spring IoC container. prototype. Scopes a single bean definition to any number of object instances.
What is bean in Spring?
In Spring, the objects that form the backbone of your application and that are managed by the Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and otherwise managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your application.
What is the difference between @component and @bean?
If we see component class like @Controller, @service, @repository will be scan automatically by the spring framework using the component scan. @Bean on the other hand can only be used to explicitly declare a single bean in a configuration class.
What is MVC in Spring?
The Spring Web MVC framework provides Model-View-Controller (MVC) architecture and ready components that can be used to develop flexible and loosely coupled web applications.
What is @EnableAutoConfiguration in Spring boot?
The @EnableAutoConfiguration annotation enables Spring Boot to auto-configure the application context. Therefore, it automatically creates and registers beans based on both the included jar files in the classpath and the beans defined by us.
What is REST vs SOAP?
SOAP (Simple Object Access Protocol) is a standards-based web services access protocol that has been around for a long time. Originally developed by Microsoft, SOAP isn’t as simple as the acronym would suggest. REST (Representational State Transfer) is another standard, made in response to SOAP’s shortcomings.
What is difference between REST and RESTful?
Put simply, there are no differences between REST and RESTful as far as APIs are concerned. REST is the set of constraints. RESTful refers to an API adhering to those constraints. It can be used in web services, applications, and software.
What are the types of API?

- Partner APIs. …
