A memo that touched Spring Boot

Features of Spring Boot

It seems that it is a big feature that it is possible to program ignoring the existence of Servlet like other languages by using annotations.

Reference

Annotation Overview
@ Conponent The most basic annotation to register as a bean in the DI container
@ Configuration Annotation for Java-based bean definition * I don't understand what you mean, so I will explain it later.
@ Repository Annotation indicating a class for handling data storage and loading. When using a database such as Spring Data, there are cases where it has a special meaning, such as allowing the table to be accessed automatically by specifying this annotation.
@ Controller Annotation indicating that it is an MVC controller class.
@ Service Annotation indicating a class for handling business logic etc.

As a special thing in each subproject, different annotations are defined, overriding these annotations.

Annotation Overview
@ SpringBootApplication Annotations used as a convention to specify the main program of a Spring Boot application
@ RestController Annotation for registering as a controller for REST
@ RestControllerAdvice Annotation for defining common processing such as conversion of input data format common to each controller and error processing.

--When using maven --If you list the dependency packages in the pom.xlm file, the required packages will be loaded automatically. --ʻApplication.properties` A place to list the settings used in each package. --When using gradle ――I plan to use it from now on

Spring Boot Actuator A service that provides functions such as monitoring, metrics, and auditing. Just deploy and automatically apply audit, health, and metric collection to your application.

As a caveat, if the endpoint is set to a point without authentication, there is a risk that the security information of the server will be disclosed, so it is necessary to carefully develop the endpoint disclosure.
