How can the migration from Spring Boot to Micronaut be achieved?

To migrate a Spring Boot project to Micronaut, you can follow these steps:

1. Create a Micronaut project: either use the Micronaut CLI or create a new Micronaut project using the official initial project template provided by Micronaut.
2. Copy the code and resource files: Copy the code and resource files from the Spring Boot project to the corresponding locations in the Micronaut project. Make sure the directory structure and file names remain consistent.
3. Update Dependencies: Open the build file of your Micronaut project (e.g. pom.xml or build.gradle), replace the dependencies used in the original Spring Boot project with the corresponding Micronaut dependencies. Refer to the Micronaut documentation for the correct dependencies.
4. Adjusting configuration files: Fit the configuration file from the Spring Boot project (such as application.properties or application.yml) into the configuration file format used by the Micronaut project. Since Micronaut uses different file names and formats for configuration files, you will need to adjust the content of the configuration file accordingly.
5. Adjust the code: make appropriate adjustments to the code in the original Spring Boot project based on the features and usage of Micronaut. Micronaut offers new annotations and functions that can be used to replace the corresponding features in Spring Boot.
6. Testing and debugging: Run the Micronaut project and ensure all functions are working properly. You may need to conduct some testing and debugging to ensure a successful project migration.

The above steps are simply general guidelines, specific steps may vary depending on the complexity of the project and the functionality being migrated. During the migration process, please refer to the official Micronaut documentation and sample projects for more detailed guidance and assistance.
