小编Ami*_*cha的帖子

我是Neo4J的新手并尝试通过java连接到Neo4J服务器.

我的独立项目的pom条目如下:

<dependency>
            <groupId>org.neo4j</groupId>
            <artifactId>neo4j-ogm-core</artifactId>
            <version>2.0.1</version>
        </dependency>
        <dependency>
            <groupId>org.neo4j</groupId>
            <artifactId>neo4j-ogm-http-driver</artifactId>
            <version>2.0.1</version>
        </dependency>
        <dependency>

此项目位于Java EE项目的类路径中,并在tomcat上作为war部署.

我的代码试图按如下方式打开会话:

Configuration configuration = Components.configuration();
        configuration.driverConfiguration()
                     .setDriverClassName("org.neo4j.ogm.drivers.http.driver.HttpDriver")
                     .setURI("http://localhost:7474")
                     .setCredentials("xxxx", "xxxx");
SessionFactory sessionFactory = new SessionFactory("com.myapp.infra.transaction");
sessionFactory.openSession();

最后一行是抛出以下错误:

org.neo4j.ogm.exception.ServiceNotFoundException: Driver:
org.neo4j.ogm.drivers.http.driver.HttpDriver
at org.neo4j.ogm.service.DriverService.load(DriverService.java:51)
at org.neo4j.ogm.service.DriverService.load(DriverService.java:63)
at org.neo4j.ogm.service.Components.loadDriver(Components.java:126)
at org.neo4j.ogm.service.Components.driver(Components.java:84)
at org.neo4j.ogm.session.SessionFactory.openSession(SessionFactory.java:79)

我没有使用Spring,代码使用的是JDK 7.任何帮助都非常有用.

谢谢!:)

我从https://github.com/corda/cordapp-template-java下载cordapp模板（Java）。

每次我更改gradlew deplyNodes项目时都会失败，并显示以下错误。但是，重新启动系统后，它会自动解决。

有什么我想念的吗？
