Spring profiles

Spring profiles are a feature of the Spring Framework that allows developers to configure and customize their applications based on different runtime environments or deployment scenarios. Spring profiles can be used to manage different sets of configuration properties, beans, and other components in an application.

For example, you may have different configurations for your application when it's running in a development environment versus a production environment. With Spring profiles, you can define separate configuration files or use annotations to indicate which configuration should be used for a specific environment. When you launch your application, you can specify which profile to activate, and Spring will load the appropriate configuration.

To use Spring profiles, you can define profiles in your configuration files using the spring.profiles.active property, or you can use annotations like @Profile to activate a specific profile. You can also use the spring.profiles.default property to specify a default profile that will be used if no other profile is activated.

Overall, Spring profiles provide a powerful mechanism for managing application configuration and customization based on different runtime environments and deployment scenarios.

Creating an synchronous HTTP request using Spring RestTemplate

While RestTemplate is now in maintenance mode and WebClient is recommended for new applications, it’s still widely used in existing projects. Here’s how you can configure and use RestTemplate in a Spring Boot application: 1. Add Dependencies Ensure the following dependency is present in your pom.xml : < dependency > < groupId > org.springframework.boot </ groupId > < artifactId > spring-boot-starter-web </ artifactId > </ dependency > 2. Configure a RestTemplate Bean Define a RestTemplate bean in a configuration class to enable dependency injection: import org.springframework.boot.web.client.RestTemplateBuilder; import org.springframework.context. annotation .Bean; import org.springframework.context. annotation .Configuration; import org.springframework.web.client.RestTemplate; @Configuration public class RestTemplateConfig { @Bean public RestTemplate restTemplate(RestTemplateBuilder builder) { ret...

how to delete all issues on project in sentry, 센트리 이슈 삭제하기

As of now, Sentry doesn't have a direct feature to delete all issues in bulk through the web interface. However, there are a few methods you can use to archive, resolve, or delete issues programmatically or by adjusting project settings: 1. Bulk Archive Issues from the Web Interface Though there is no mass delete option, you can bulk archive or resolve issues, which essentially hides them from active issue lists. Steps: Go to your Sentry project. In the issue list view, select the issues you want to archive or resolve. Use the "Select All" checkbox to select multiple issues. Choose "Resolve" or "Archive" from the bulk action dropdown. However, this doesn't delete the issues permanently; they will be archived or marked as resolved. 2. Adjust Retention Policy (Data Retention Settings) If you're looking to remove older issues, you can adjust the retention policy at the organization level. Sentry allows you to configure how long issue...

max_active_runs of Airflow

In Apache Airflow, if you want to ensure that a new run of a DAG doesn’t start before the previous one has completed, you can use the max_active_runs parameter in the DAG definition. Setting this parameter to 1 ensures that only one instance of the DAG is running at any given time. Setting max_active_runs for a DAG Here’s an example of how to set up a DAG with max_active_runs=1 : from airflow import DAG from airflow.operators.dummy_operator import DummyOperator from datetime import datetime # Define the DAG with DAG( 'my_dag' , description= 'A sample DAG' , schedule_interval= '@daily' , # Set your schedule start_date=datetime( 2023 , 1 , 1 ), catchup= False , max_active_runs= 1 # This prevents new runs before the previous run completes ) as dag: # Define tasks start = DummyOperator(task_id= 'start' ) end = DummyOperator(task_id= 'end' ) # Define task dependencies ...

Read a file in Java, 자바 파일 읽기

To convert a File object into an InputStream in Java, you can use the FileInputStream class. Here's an example: import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.InputStream; public class FileToInputStreamExample { public static void main(String[] args) { File file = new File( "path/to/file.txt" ); try { InputStream inputStream = new FileInputStream(file); // Use the inputStream as needed... // Close the inputStream when you're done inputStream.close(); } catch (IOException e) { e.printStackTrace(); } } } In the code above, replace "path/to/file.txt" with the actual path to your file. The FileInputStream class is used to create an input stream from the file. You can then use the inputStream object to read the contents of the file or perform any other operations you need. Finally, rem...

dagrun_timeout of Airflow

In Apache Airflow, you can set a timeout for an entire DAG run using the dagrun_timeout parameter in the DAG definition. This parameter allows you to specify the maximum amount of time a DAG run is allowed to execute. If the DAG run exceeds this time limit, it will be marked as failed, and all running tasks in that run will be terminated. Setting dagrun_timeout Here's how to set a timeout for a DAG run: from airflow import DAG from airflow.operators.dummy_operator import DummyOperator from datetime import datetime, timedelta # Define the DAG with DAG( 'my_dag_with_timeout', description='A DAG with a run timeout', schedule_interval='@daily', start_date=datetime(2023, 1 , 1 ), catchup=False, dagrun_timeout=timedelta(hours=2) # Set a 2-hour timeout for the entire DAG run ) as dag: # Define tasks start = DummyOperator( task_id='start') end = DummyOperator( task_id='end') # Define ta...

ssh-copy-id in ansible

ssh-copy-id is a command-line tool used to copy your public SSH key to a remote server's authorized_keys file, allowing you to log in to the server without entering a password. Ansible is an open-source automation tool used to manage and configure multiple remote servers simultaneously. In Ansible, you can use the authorized_key module to manage the authorized keys of remote servers. This module allows you to add, remove, or replace SSH keys in a remote user's authorized_keys file. To add your public SSH key to a remote server using Ansible, you can use the authorized_key module. Here's an example playbook that adds your public SSH key to a remote server's authorized_keys file: - name: Add SSH key to authorized_keys hosts: your_server become: true tasks: - name: Install SSH key for current user authorized_key: user: your_username key: " {{ lookup('file', '/path/to/your/public/key/id_rsa.pub') }} " ...
