Are annotations better than XML for configuring Spring?

Are annotations better than XML for configuring Spring?

Annotations have their use, but they are not the one silver bullet to kill XML configuration. I recommend mixing the two! For instance, if using Spring, it is entirely intuitive to use XML for the dependency injection portion of your application.

Is XML still used in Spring?

1 Answer. XML configuration is still officially supported by Spring.

What is difference between Java-based configuration and annotation based configuration?

They are similar, but have subtle differences. Instead of having an @Component annotation on your class( which is annotation-based configuration ), you can skip the @Component and instead have a @Bean annotated method which returns a new instance of this class. ( this is Java-based configuration).

What are the advantages of Java config?

Advantages of Java Config over XML Config

• Compile-Time Feedback due to Type-checking. Let’s say that we can make a mistake during configuration.
• Refactoring Tools for Java without special support/plugins work out of the box with Java Config (special support needed for XML Config)

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.

What is the difference between the configuration types XML and annotation?

Xml configuration is very good to get a bigger picture of application but it maybe cumbersome to find some errors until runtime. In this case Spring @Configuration annotation sounds as a better choice since it let you see a bigger picture as well and also allows to validate configuration on compile time.

Can we do XML configuration in spring boot?

We need to use @ImportResource with @Configuration in our spring boot application. To load XML configuration, @ImportResource is used as follows. @ImportResource(“classpath:app-config.xml”) We will use @ImportResource with @SpringBootApplication in our spring boot application.

Why we use XML in spring?

What are the disadvantages of Spring framework?

Disadvantages of Spring Framework

• Complexity — The Spring framework has a lot of variables and complications.
• Parallel Mechanisms — One of the biggest advantages of Spring is that it gives developers a wide array of options, but this could also be a disadvantage because it causes confusion.

Does spring boot use XML?

Spring allows you to configure your beans using Java and XML.

How to write Spring configuration without XML in Java?

Java-based configuration option enables you to write most of your Spring configuration without XML but with the help of few Java-based annotations explained in this chapter. @Configuration & @Bean Annotations Annotating a class with the @Configuration indicates that the class can be used by the Spring IoC container as a source of bean definitions.

What is @configuration in Spring Boot Java?

Java-based configuration option enables you to write most of your Spring configuration without XML but with the help of few Java-based annotations explained in this chapter. @Configuration & @Bean Annotations. Annotating a class with the @Configuration indicates that the class can be used by the Spring IoC container as a source of bean definitions.

How to configure Spring Framework?

There are two ways to configure Spring. One is to add annotations to your Java code. This is java-based, this is annotation-based, and it is autowiring. So java-based and annotation based are the same thing. The other way is to configure Spring is by using an xml file.

What is the difference between XML configuration files and Bean wiring?

In other words, there is XML configuration files yet but bean wiring, is configured using annotations. Note: Annotation injection is performed before XML injection. Thus, the latter configuration will override the former for properties wired through both approaches.
