Spring Boot Starter Actuator use tutorial

Spring Boot Starter Actuator Tutorial Spring Boot Starter Actuator is a very powerful monitoring and management tool provided by Spring Boot, which can help developers better understand and manage the Spring Boot applications in the operation.This tutorial will introduce how to use the Spring Boot Starter Actuator to monitor and manage your application and provide relevant code examples and configuration descriptions. Step 1: Add dependencies First of all, you need to add Spring Boot Starter Actuator to your Spring Boot project.You can add the following code to the pom.xml file of the project to introduce Actuator -related dependencies: <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> </dependencies> Step 2: Configure Actuator endpoint Spring Boot Starter Actuator provides many useful endpoints for monitoring and managing applications.You can enable these endpoints by configuration files or code.Here are some commonly used endpoints and their configuration examples: -HEALTH: Used to check the health state of the application.You can use the following configuration in the configuration file to enable this endpoint: yaml management: endpoints: web: exposure: include: health -Info: Used to obtain information about applications.You can use the following configuration in the configuration file to enable this endpoint: yaml management: endpoints: web: exposure: include: info There are many other endpoints that can be configured and enabled. You can choose the corresponding endpoints according to your needs to monitor and manage your application. Step 3: Visit the end point of Actuator Once your application runs and is equipped with an Actuator endpoint, you can access these endpoints through the following URL: -Card check -out endpoint:/actuator/health -Ax information endpoint:/actuator/info You can enter the above URL in the browser, or use the CURL command to get the corresponding information. Step 4: Custom ActualOR endpoint In addition to using the default Actuator endpoint, you can also customize some custom endpoints to monitor and manage your application.This function can be implemented by writing a custom Actualor endpoint class.The following is an example: @Component @Endpoint(id = "custom") public class CustomEndpoint { @ReadOperation public String getCustomInformation() { return "This is a custom endpoint."; } } In the above example, we created a custom end point called "Custom" and defined a method for obtaining custom information. Step 5: Access custom Actuator endpoint Access custom Actual's endpoint is similar to access -default endpoints.Just access the custom endpoint through the following URL: /custom You can enter the above URL in the browser, or use the CURL command to obtain the custom information returned by the custom endpoint. So far, we have completed the tutorial of using Spring Boot Starter Actuator to monitor and manage applications.You have learned to add an Actualor dependencies, configuration, and enable endpoints, and access the default and custom endpoints.I hope this tutorial will help you.
