java – 如何在使用spring-data-neo4j时启用neo4j webadmin？

我正在从Accessing Neo4j Data with REST示例引导一个新项目.该示例使用嵌入式数据库而不是独立的neo4j服务器,但我想使用Neo4J webadmin接口来显示我的数据.如何从此配置启动webadmin界面？

(他们让WrappingNeoServerBootstrapper在use WrappingNeoServerBootstrapper with spring-data-neo4j工作,但是从答案中省略了很多知识,例如甚至没有提到在配置中的位置.作为POM的新手,Spring Boot和Neo4j因此我不能利用那个答案.)

解决方法:

你正在使用的example需要一些调整来启用Neo4j浏览器.我从一个不同的例子开始,Accessing Data with Neo4j的例子,它运作良好.

您需要执行以下操作：

>将弹簧靴pom上的版本更改为1.2.1.请：

 <parent>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-parent</artifactId>
     <version>1.2.1.RELEASE</version>
 </parent>

>为Neo4jServer添加依赖项：

<dependency>
    <groupId>org.neo4j.app</groupId>
    <artifactId>neo4j-server</artifactId>
    <version>2.1.5</version>
</dependency>
<dependency>
    <groupId>org.neo4j.app</groupId>
    <artifactId>neo4j-server</artifactId>
    <version>2.1.5</version>
    <classifier>static-web</classifier>
</dependency>

>在Application.class中实现Spring Boot命令行运行程序：

 public class Application extends Neo4jConfiguration implements CommandLineRunner{

>在Application.class中自动添加对GraphDatabaseService的引用：

@Autowired
GraphDatabaseService db;

> @Override Application.class中CommanLineRunner的run方法：

@Override
public void run(String... strings) throws Exception {
    // used for Neo4j browser
    try {
        WrappingNeoServerBootstrapper neoServerBootstrapper;
        GraphDatabaseAPI api = (GraphDatabaseAPI) db;

        ServerConfigurator config = new ServerConfigurator(api);
        config.configuration()
            .addProperty(Configurator.WEBSERVER_ADDRESS_PROPERTY_KEY, "127.0.0.1");
        config.configuration()
            .addProperty(Configurator.WEBSERVER_PORT_PROPERTY_KEY, "8686");

        neoServerBootstrapper = new WrappingNeoServerBootstrapper(api, config);
        neoServerBootstrapper.start();
    } catch(Exception e) {
        //handle appropriately
    }
    // end of Neo4j browser config
}

完成所有操作后,Application.class应如下所示：

package hello;

import org.neo4j.graphdb.GraphDatabaseService;
import org.neo4j.graphdb.factory.GraphDatabaseFactory;
import org.neo4j.kernel.GraphDatabaseAPI;
import org.neo4j.server.WrappingNeoServerBootstrapper;
import org.neo4j.server.configuration.Configurator;
import org.neo4j.server.configuration.ServerConfigurator;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.data.neo4j.config.EnableNeo4jRepositories;
import org.springframework.data.neo4j.config.Neo4jConfiguration;
import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration;

@Configuration
@EnableNeo4jRepositories
@Import(RepositoryRestMvcConfiguration.class)
@EnableAutoConfiguration
public class Application extends Neo4jConfiguration implements CommandLineRunner{

    public Application() {
        setBasePackage("hello");
    }

    @Bean(destroyMethod = "shutdown")
    public GraphDatabaseService graphDatabaseService() {
        return new GraphDatabaseFactory().newEmbeddedDatabase("target/hello.db");
    }

    @Autowired
    GraphDatabaseService db;



    @Override
    public void run(String... strings) throws Exception {
        // used for Neo4j browser
        try {
            WrappingNeoServerBootstrapper neoServerBootstrapper;
            GraphDatabaseAPI api = (GraphDatabaseAPI) db;

            ServerConfigurator config = new ServerConfigurator(api);
            config.configuration()
                    .addProperty(Configurator.WEBSERVER_ADDRESS_PROPERTY_KEY, "127.0.   0.1");
            config.configuration()
                    .addProperty(Configurator.WEBSERVER_PORT_PROPERTY_KEY, "8686");

            neoServerBootstrapper = new WrappingNeoServerBootstrapper(api, config);
            neoServerBootstrapper.start();
        } catch(Exception e) {
            //handle appropriately
        }
        // end of Neo4j browser config
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }


}

Neo4j浏览器将在run()方法中配置的主机和端口上可用.
