java What does @Configuration *really* mean in Spring Boot?

It is therefore behaviorally equivalent to removing the @Configuration stereotype. See @EnableAsync, @EnableScheduling, @EnableTransactionManagement, @EnableAspectJAutoProxy, and @EnableWebMvcfor details. In the case of software, configuration can also refer to the application’s settings.

By virtue of being a nested @Configurationclass, DatabaseConfig will be registered automatically. This avoids the need to use an @Import annotation when the relationship between AppConfig and DatabaseConfig is already implicitly clear. Information about can be obtained from the operating system. For example, in the case of Windows-based operating systems, on selecting the “Properties” option on “My Computer,” information on the operating system version, processor details and RAM information are provided.


The @TestConfiguration annotation is also annotated with the @TestComponent annotation in its definition to indicate that this annotation should only be used for testing. Before that, let us create a Spring Boot project with the help of the Spring Boot Initializr, and then open the project in our favorite IDE. Specify whether @Bean methods need to have unique method names, raising an exception otherwise in order to prevent accidental overloading.


Any secret data like passwords and keys should be identified and securely encrypted and stored. At this point configuration data should be organized into data files that can be pointed to as a central source of truth. The rise of cloud infrastructures has led to the development and adoption of new patterns of infrastructure management. Complex, cloud-based system architectures are managed and deployed through the use of configuration data files. These new cloud platforms allow teams to specify the hardware resources and network connections they need provisioned through human and machine readable data files like YAML.

Jira Service Management

Configuration Management originated in the United States Department of Defense in the 1950s as a technical management discipline for hardware material items—and it is now a standard practice in virtually every industry. This marked the beginning of what has now evolved into the most widely distributed and accepted standard on CM, ANSI–EIA–649–1998. Many of these functions and models have redefined CM from its traditional holistic approach to technical management. Some treat CM as being similar to a librarian activity, and break out change control or change management as a separate or stand alone discipline. CM applied over the life cycle of a system provides visibility and control of its performance, functional, and physical attributes. CM verifies that a system performs as intended, and is identified and documented in sufficient detail to support its projected life cycle.


Configuration data can be overlooked at times, but it is critical to system operation. @TestConfiguration annotation allows us to define additional beans or override existing beans in the Spring application context to add specialized configuration for testing. We will use this project to create our service class and bean configurations and then write tests using the @TestConfiguration annotation. Suppose we have already a Java project and all the Spring JAR files are imported into that project. Now let’s create a simple class named College and inside the class, we have a simple method.

Spring @Configuration annotation is part of the spring core framework. Spring Configuration annotation indicates that the class has @Bean definition methods. Configuration audits are broken into functional and physical configuration audits. They occur either at delivery or at the moment of effecting the change. Configuration identification is the process of identifying the attributes that define every aspect of a configuration item. A configuration item is a product (hardware and/or software) that has an end-user purpose.

  • This feature requires method interception, implemented through a runtime-generated CGLIB subclass which comes with limitations such as the configuration class and its methods not being allowed to declare final.
  • The bean overriding feature is disabled by default from Spring Boot 2.1.
  • To start, network configuration means thinking about what policies you’d like to apply to your network.
  • DisclaimerAll content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only.

These policies inform what settings you apply, how you maintain the network, how data flows and what controls you put in place. At its core, network configuration is all about establishing policies, assigning network settings, flows and controls. Configuring your network is critical to support traffic, improve network security and increase network stability. However, we need to enable this feature during testing if we want to override one or more bean definitions. Turning off bean method interception effectively processes @Beanmethods individually like when declared on non-@Configuration classes, a.k.a. “@Bean Lite Mode” (see @Bean’s javadoc).

Configuration management database

A complete CM program includes provisions for the storing, tracking, and updating of all system information on a component, subsystem, and system basis. After configuration components data has been aggregated and organized a baseline can be established. A baseline configuration is a known state of configuration that will successfully operate the dependent software without error. This baseline is usually created by reviewing the configuration of a functioning production environment and committing those configuration settings.


It gave this system and various iterations very technical names, until in 2001 it published a consolidated guidebook that established the technical management system now called configuration management. Today, configuration management is not only used by the defense department, but in software development,IT service management, civil engineering, industrial engineering, and more. Use @Configuration annotation on top of any class to declare that this class provides one or more @Bean methods and may be processed by the Spring container to generate bean definitions and service requests for those beans at runtime. With the advent of plug and play technology, most configurations can be performed automatically in the case of software configurations. The quality of performance and life of the computer or device depends on its configuration. Most important aspects of a configuration are the speed of the processor, speed and stability provided by the motherboard, speed and size of storage, graphical display and software drivers.

Testing with Spring Boot’s @TestConfiguration Annotation

This might fail if we run our test as part of any automated test or in any other environment with restricted connectivity. The default is true, allowing for ‘inter-bean references’ via direct method calls within the configuration class as well as for external calls to this configuration’s @Bean methods, e.g. from another configuration class. If this is not needed since each of this particular configuration’s @Beanmethods is self-contained and designed as a plain factory method for container use, switch this flag to false in order to avoid CGLIB subclass processing. Note, however, that explicit registration of a PropertySourcesPlaceholderConfigurer via a static @Beanmethod is typically only required if you need to customize configuration such as the placeholder syntax, etc.


The benefits of a CMS/CMDB includes being able to perform functions like root cause analysis, impact analysis, change management, and current state assessment for future state strategy development. Example systems, commonly identifies themselves as IT Service Management systems, include FreshService, ServiceNow and Samanage. DevOps configuration is the evolution and automation of the systems administration role, bringing automation to infrastructure management and deployment. Checking your network configuration is often the first step to network troubleshooting. Node.js is a popular server-side runtime engine based on JavaScript to build and run web applications.

Webopedia is an online information technology and computer science resource for IT professionals, students, and educators. Webopedia focuses on connecting researchers with IT resources that are most helpful for them. Webopedia resources cover technology definitions, educational guides, and software reviews that are accessible to all researchers regardless of technical background. We can use @Component annotation for creating the bean for this class.
