Endpoint List
Some of the actuator endpoints are as follows:
▶ actuator/health
Shows the application status
▶ actuator/info
Show the application information. For this, you have to add the information yourself
Use the property name below in the application.properties file to add information. This creates a JSON object with each name coming after the comma becoming the child of what comes before
info.<name>.<name>=<value>
▶ actuator/beans
Shows the bean list registered on the application context
▶ actuator/mappings
Shows all the paths registered as @RequestMapping
Adding Endpoints
▶ Certain Endpoints
By default only the /health endpoint is available. For the rest, we have to add them in the application.properties file using the include property
management.endpoints.web.exposure.include=<endpoint1>,<endpoint2>
▶ All Endpoints
Use * to add all endpoints
management.endpoints.web.exposure.include=*Removing Endpoints
▶ Certain Endpoints
If you want to remove some endpoints after adding all the endpoints, use exclude
management.endpoints.web.exposure.exclude=<endpoint1>,<endpoint2>Implementation
Add the dependency in the pom.xml file
Run the app then go to the URL. The browser will show as follows
Some of the endpoints have sensitive information that you don't want to expose to the public. Click the link below to add security
