我正在尝试从 Spring Boot 启动器连接到本地安装的 Neo4j 服务器-> gs-accessing-neo4j-data-rest http://spring.io/guides/gs/accessing-neo4j-data-rest/

服务器安装是默认通过 Homebrew 安装的。

Gradle 构建文件

buildscript {
repositories {
    maven { url "http://repo.spring.io/libs-milestone" }
    mavenLocal()
}
dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:1.0.0.RC5")
}
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'

jar {
    baseName = 'gs-accessing-neo4j-data-rest'
    version = '0.1.0'
}

repositories {
    mavenCentral()
    maven { url "http://repo.spring.io/libs-snapshot" }
}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    compile("org.springframework.data:spring-data-neo4j:3.0.1.RELEASE")
    compile("org.hibernate:hibernate-validator")
    compile("org.springframework.data:spring-data-rest-webmvc")
    compile("org.springframework.data:spring-data-neo4j-rest:3.0.1.RELEASE") <---ADDED
}

task wrapper(type: Wrapper) {
    gradleVersion = '1.11'
}

应用程序.java

package hello;

import org.neo4j.graphdb.GraphDatabaseService;
import org.neo4j.graphdb.factory.GraphDatabaseFactory;
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.neo4j.rest.SpringRestGraphDatabase;
import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration;

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

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

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

    @Bean
    SpringRestGraphDatabase graphDatabaseService() {
        return new SpringRestGraphDatabase("http://localhost:7474/db/data");
    }   

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

没有进行任何其他更改。

实际错误：

尝试添加 neo4j 的依赖项：

compile("org.neo4j:neo4j-rest-graphdb:2.0.1")

我遇到过同样的问题。看来 Jersey 是必需的，并且不包含在传递依赖项中。

compile('com.sun.jersey:jersey-core:1.18.1')

它有效。
