# Spring Data Neo4j Integration Patterns ## Overview Provides Spring Data Neo4j integration patterns for Spring Boot applications. Covers node entity mapping with `@Node` and `@Relationship`, repository configuration (imperative and reactive), custom Cypher queries with `@Query`, and integration testing with embedded Neo4j databases. ## When to Use Use this skill when working with: - Graph databases and Neo4j integration in Spring Boot - Node entities, relationships, and Cypher queries - Spring Data Neo4j repositories (imperative or reactive) - Neo4j testing with embedded databases ## Instructions ### 1. Set Up Spring Data Neo4j **Add the dependency:** Maven: ```xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-neo4j</artifactId> </dependency> ``` Gradle: ```groovy implementation 'org.springframework.boot:spring-boot-starter-data-neo4j' ``` **Configure connection in application.properties:** ```properties spring.neo4j.uri=bolt://localhost:7687 spring.neo4j.authentication.username=neo4j spring.neo4j.authentication.password=secret ``` **Configure Cypher-DSL dialect (recommended):** ```java @Configuration public class Neo4jConfig { @Bean Configuration cypherDslConfiguration() { return Configuration.newConfig() .withDialect(Dialect.NEO4J_5).build(); } } ``` > **Validation Checkpoint**: Run `MATCH (n) RETURN count(n)` via cypher-shell to verify the connection works before proceeding...
