連接Neo4J與SpringBoot

Question

我需要幫助連接neo4j數據庫到彈簧引導。我整天都在搜索，但無法弄清楚。我可以創建一個Spring引導應用程序，創建一個REST控制器調用服務，然後創建SQl的Spring數據JPA存儲庫，但無法爲圖形數據庫執行此操作。任何人都可以幫助我配置Graph數據庫以進行引導。 我是Neo4j的新手，並已分配任務。

謝謝。 我說什麼任何教程告訴我：

我主要是：

@SpringBootApplication(exclude = { Neo4jDataAutoConfiguration.class }) 
@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class }) 
public class AppBootConfig extends SpringBootServletInitializer { 
public static void main(String[] args) { 
    SpringApplication.run(AppBootConfig.class, args); 
    } 
} 

我試圖來配置，但得到這個：

Answer 1

首先，你的聚甲醛是相當混亂。只添加所需的依賴關係。你只需要這個

<dependency> 
     <groupId>org.springframework.data</groupId> 
     <artifactId>spring-data-neo4j</artifactId> 
     <version>4.1.5.RELEASE</version> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework.data</groupId> 
     <artifactId>spring-data-neo4j-rest</artifactId> 
     <version>3.4.6.RELEASE</version> 
</dependency> 

主類中應該有這樣的事情

@SpringBootApplication 
@EnableNeo4jRepositories("com.in.neo4j.repository.neo") 

我不知道你爲什麼不包括一些autoconfigurations
