spring-boot 集成Neo4j

1.maven依赖

	<!-- neo4j -->
	<dependency>
	    <groupId>org.neo4j.driver</groupId>
	    <artifactId>neo4j-java-driver</artifactId>
	    <version>4.0.0</version>
	</dependency>		

2.配置类

import org.neo4j.driver.AuthTokens;
import org.neo4j.driver.Driver;
import org.neo4j.driver.GraphDatabase;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class Neo4jUtil {
    @Value("${spring.data.neo4j.uri}")
    private String uri;
    @Value("${spring.data.neo4j.username}")
    private String username;
    @Value("${spring.data.neo4j.password}")
    private String password;
    public Driver createDriver() {
        Driver driver = GraphDatabase.driver(uri,
                AuthTokens.basic(username, password));
        return driver;
    }
}

3.使用

import org.neo4j.driver.*;
public class myNeoTest{
	@Autowired
    private Neo4jUtil neo4jUtil;
    
    private void executeCql(String cql){
		Driver driver = neo4jUtil.createDriver(); 
		Session session = driver.session(); 
		Transaction transaction = session.beginTransaction()
		//带参
		//Result run = transaction.run(cql, param);
		Result run = transaction.run(cql);
        if (run.hasNext()) {
        	//有返回值-打印内容
        	System.out.println(run.next());
        }
        transaction.commit();
		
		//记得关闭
    }
}
