To include Starter Web in the Spring application, add the following dependency Spring Boot selects a recent version of Spring Data modules for you. Otherwise, properties are discovered through the presence of standard getters and setters with special handling for collection and map types (that is detected even if only a getter is present). Auto-completes valid logger names and logger groups. As of May 21st of 2021, The latest stable spring boot version is 2.5.0. For example, if the group were based on a @Bean method annotated with @ConfigurationProperties, this attribute would contain the fully qualified name of the @Configuration class that contains the method. As Spring Boot defines a few logger groups out-of-the-box, dedicated value hints have been added for those. A list of valid values as defined by the ValueHint object (described in the next table). If the property refers to a map (such as system.contexts), the hint either applies to the keys of the map (system.contexts.keys) or the values (system.contexts.values) of the map. We'll cover the basics first, then discuss in detail what's available in Spring Boot 2.x vs 1.x. To include Starter Web in the Spring application, add the following dependency http-common.ts initializes axios with HTTP base Url and headers.

Broadly Speaking, Apache Kafka is software where topics (A topic might be a category) can be defined and further processed. Provide starter dependencies to simplify the build configuration. Below is the code for the KafkaConfig.java file. Make sure you have changed the port number in the application.properties file, Lets run the Spring boot application inside the ApacheKafkaConsumerApplication file.

The logger-name provider auto-completes valid logger names and logger groups. The @Id annotation makes the annotated field the _id of our document, being the unique identifier in this index.
