1. How to Implement Geospatial Queries in Spring Boot with PostgreSQL
Integrating geospatial queries into a Spring Boot application with PostgreSQL and PostGIS enhances applications with strong geospatial capabilities, enabling developers to create efficient, dynamic, and useful applications for various fields requiring spatial data.
The guide equips developers with the tools and techniques to handle geospatial data and explore its vast possibilities in their applications.
2. How to Use Asynchronous in Cache Library Caffeine
The article emphasizes the benefits of using asynchronous updates and the Caffeine caching library in terms of efficiently managing geospatial data and handling outdated data.
It reiterates key points about using
refreshAfterWrite
to control the frequency of updates, the importance of providing abuildFunction
for asynchronous updates, and the inability of asynchronous updates to modify non-existent keys due to expiration or capacity limits.
3. Implement Update-Or-Insert in Spring Data JPA
The article covers different methods for upsert operations in Spring Data JPA, including repository methods, custom logic, and database built-in features.
It includes implementation examples and unit tests to verify each approach's functionality. Although databases provide built-in upsert features, implementing custom logic in Spring Data JPA based on the ID column is relatively straightforward.
