June 1, 2023July 24, 2023@PropertySource vs @PropertySources 2 Annotations Overview (2023)@PropertySource and @PropertySources AnnotationsIn Spring Framework, the @PropertySource annotation is used to specify the source of external property files that contain key-value pairs. These properties can be injected into Spring beans using the @Value annotation or by using the Environment object.Here’s an example of how to use @PropertySource in a Spring application:Create a properties file, for example, application.properties, and place it in the classpath of your application. This file can contain key-value pairs like key=value, where the key represents the property name and the value represents the property value.In your Spring configuration class, annotate it with @PropertySource and specify the location of the properties file. You can specify multiple @PropertySource annotations to load properties from multiple files.import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.PropertySource; @Configuration @PropertySource("classpath:application.properties") public class AppConfig { // Configuration code... } In the example above, application.properties is located in the classpath. You can also specify a file system path using the file: prefix or a URL using the http: or https: prefixes.Once you have configured the @PropertySource, you can inject the properties into your beans using the @Value annotation or by using the Environment object.import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Component; @Component public class MyComponent { @Value("${key}") private String value; // ... } In the example above, the value of the key property from the application.properties file will be injected into the value field of the MyComponent bean.That’s a basic example of how to use @PropertySource in Spring to load external properties into your application. By using this annotation, you can easily externalize configuration and make your application more flexible and configurable.Like this:Like Loading...Related Java Java Interview Question @propertysource@propertysourcesannotation property sourcecalling microservice using gateway and eurekajava annotationsspring @propertysource examplespring annotationsspring bean annotationsspring boot : how to use @propertysource to point to a texspring boot @propertysource annotation with examplespring boot and mysqlspring boot annotationsspring core annotationsspring data annotationsspring web annotations
