使用 spring-data-neo4j 时如何启用 neo4j webadmin？

Question

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 界面来可视化我的数据。如何从这个配置开始启用 webadmin 界面？

（他们让 WrappingNeoServerBootstrapper 在 use WrappingNeoServerBootstrapper with spring-data-neo4j 中工作，但答案中省略了很多知识，例如，甚至没有提到配置的位置。作为 POM 的新手，Spring Boot 和 Neo4j 因此我不能使用那个答案。）

Answer 1

example you are using needs some tweaking to enable the Neo4j browser. I started from a different example, the Accessing Data with Neo4j 示例，效果很好。

您需要执行以下操作：

将 spring 启动 pom 上的版本更改为 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：

<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>

在您的 Application.class:

中实施 Spring 启动命令行运行ner

 public class Application extends Neo4jConfiguration implements CommandLineRunner{

在您的 Application.class:
中自动装配对 GraphDatabaseService 的引用
```
@Autowired
GraphDatabaseService db;
```

@在您的 Application.class:

中覆盖 CommanLineRunner 中的运行方法

@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
}

完成后，您的 Application.class 应该如下所示：

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 浏览器将在您的 run() 方法中配置的主机和端口上可用。
