Improving Performance with Query Caching in Spring Data JPA
Query caching in Spring Data JPA helps improve performance by reducing database access for frequently executed queries. By caching query results, subsequent requests for the same query fetch data directly from the cache instead of executing a database query. This guide demonstrates how to implement query caching using Hibernate's second-level cache with Spring Data JPA and Ehcache. Step 1: Set Up the Project Add Maven Dependencies Include the following dependencies in your pom.xml file: <dependency> <groupId> org.springframework.boot </groupId> <artifactId> spring-boot-starter-data-jpa </artifactId> </dependency> <dependency> <groupId> org.springframework.boot </groupId> <artifactId> spring-boot-starter-web </artifactId> </dependency> <dependency> <groupId> com.h2database </groupId> <artifactId> h2 </artifactId> <scope> runtime </sco...
