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.
