As per Spring documentation, in general, we should define beans for service layer objects, data access objects (DAOs), presentation objects, infrastructure objects such as Hibernate SessionFactories, JMS Queues, and so forth. So, let's create an XML configuration file, account-bean-config.xml, and define beans for our AccountService class: Spring provides different types of ApplicationContext containers suitable for different requirements. If you are creating a new project and if the configuration is specific to auto-wiring or declaring a bean - for example @Service, @Component, @Autowired - I prefer annotations. How do you choose between XML and Java Bean Configurations? The BeanFactory is the most basic version of IOC containers, and the ApplicationContext extends the features of BeanFactory. In Spring Boot, you can use appContext.getBeanDefinitionNames () to get all the beans loaded by the Spring container. Second, we'll create the UserService class and define it as a Spring bean using the @Component annotation: And then, we'll write a simple test case to test this configuration: Finally, let's take a look at XML-based configuration. The ApplicationContext is the central interface within a Spring application for providing configuration information to the application. – ConfigContainer is a Component which is used to set Context Path. It supports built-in events like ContextStartedEvent, ContextStoppedEvent, ContextClosedEvent, and RequestHandledEvent. As a matter of fact, configuring this container is like the AnnotationConfigWebApplicationContext class only, which means we can configure it in web.xml or implement the WebApplicationInitializer interface: We use the FileSystemXMLApplicationContext class to load an XML-based Spring configuration file from the file system or from URLs. The ApplicationContext is the main interface that provides configuration for an application. We may use this class when we configure Spring's ContextLoaderListener servlet listener or a Spring MVC DispatcherServlet, in a web.xml file. Launch Spring Initializr and choose the following. Web Services, How do you remember everything you studied? It's the traditional way of configuring beans in Spring. Application Context (and Bean Factory) takes care of the bean life cycle and wiring up dependencies other than a host of other features. Also, the component-scan tag tells Spring where to look for annotated classes. Previous Next This tutorial explains the difference between Application Context vs Web Application Context in spring mvc. 2.1 ApplicationContext So, now, let's see a simple example of this configuration. The context path of the spring boot application can be set in a properties file called application which is available in two formats – .properties and .yml. It also uses the JDK's standard message parsing provided by MessageFormat. Similar to FileSystemXMLApplicationContext, it's useful for test harnesses as well as for application contexts embedded within JARs. Using this approach, we can solve the problem of injecting a … SPI interface to be implemented by most if not all application contexts. This is why we use it as the default Spring container. – application.properties contains settings for prefix and suffix for JSP files and Context Path. Spring Boot does not generate code or make edits to your files. By default, spring boot will provide application context path as '/'. Then, we use a set of annotations on our Java classes, methods, constructors, or fields to configure beans. It can take classes annotated with @Configuration, @Component, and JSR-330 metadata as input. 1.1 The Bootstrap Application Context A Spring Cloud application operates by creating a “bootstrap” context, which is a parent context for the main application.
