如何在使用spring-data-neo4j时启用neo4j webadmin？ [英] How to enable neo4j webadmin when using spring-data-neo4j?

问题描述

我从使用REST访问Neo4j数据<引导新项目/ a>例子。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界面来显示我的数据。如何从此配置启动webadmin界面？

I am bootstrapping a new project from the Accessing Neo4j Data with REST example. The example uses an embedded database rather than a standalone neo4j server, but I would like to use the Neo4J webadmin interface for visualisation of my data. How do I enable the webadmin interface starting from this configuration?

（他们让WrappingNeoServerBootstrapper工作在将WrappingNeoServerBootstrapper与spring-data-neo4j一起使用，但答案中省略了很多知识，例如甚至没有提到在配置的位置。作为POM的新手，Spring Boot和Neo4j因此我可以' t使用那个答案。）

(They got WrappingNeoServerBootstrapper working in use WrappingNeoServerBootstrapper with spring-data-neo4j but a lot of knowledge is omitted from the answer, e.g. it is not even mentioned where to place to the configuration. Being new to POMs, Spring Boot and Neo4j I therefore can't make use of that answer.)

推荐答案

示例需要进行一些调整以启用Neo4j浏览器。我从一个不同的例子开始，使用Neo4j访问数据示例，它运作良好。

The example you are using needs some tweaking to enable the Neo4j browser. I started from a different example, the Accessing Data with Neo4j example and it worked well.

您需要执行以下操作：

1. 将弹簧启动pom上的版本更改为1.2.1。释放：

1. Change the version on your spring boot pom to 1.2.1.Release:

 <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：

Add dependencies for Neo4jServer:

<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命令行运行器：

Implement the Spring Boot command line runner in your Application.class:

 public class Application extends Neo4jConfiguration implements CommandLineRunner{

在Application.class中自动引用GraphDatabaseService的引用：

Autowire a reference to your GraphDatabaseService in your Application.class:

@Autowired
GraphDatabaseService db;

@Override Application.class中CommanLineRunner的run方法：

@Override the run method from CommanLineRunner in your Application.class:

@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
}

完成后，您的Application.class应如下所示：

When you are all done, your Application.class should look like this:

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。

The Neo4j browser will be available on the host and port configured in your run() method.
