Spring Data + Neo4J + Bolt 不工作答案

【问题标题】：Spring Data + Neo4J + Bolt not workingSpring Data + Neo4J + Bolt 不工作
【发布时间】：2016-08-31 11:13:58
【问题描述】：

我使用来自SDN4 Cineasts 的示例作为起点，在 SDN 和 Neo4J 之上构建我自己的应用程序。我想使用 Bolt 驱动程序，假设它不需要解析 HTTP 输出，因此更快、更安全。（如果我在这一点上错了，请纠正我。）来自 Neo github 的模板使用 HTTP 驱动程序，我无法使用 Bolt 驱动程序编译或部署示例。（我正在建造一场战争，而不是一个罐子，所以如果这有什么不同，请告诉我。）

有人可以确认添加此依赖项吗：

<dependency>
    <groupId>org.neo4j</groupId>
    <artifactId>neo4j-ogm-bolt-driver</artifactId>
    <version>${neo4j.ogm.version}</version>
</dependency>

会因为无法解析依赖而失败，并且使用高于2.0.0的任何版本号都会因为版本地狱而部署失败；或者请指出我的方式的错误？如果你这样做了，你也可以编辑ogm.properties 来读成这样（替换<your-username> 和<your-password> 酌情）：

driver=org.neo4j.ogm.drivers.bolt.driver.BoltDriver
URI=bolt://localhost
username=<your-username>
password=<your-password>
encryption.level=NONE

谢谢，

斯蒂芬

更新：根据Luanne 的建议，我添加了以下依赖项/属性：

<sdn.version>4.1.2.RELEASE</sdn.version>

<dependency>
  <groupId>org.neo4j</groupId>
  <artifactId>neo4j-ogm-bolt-driver</artifactId>
  <version>2.0.4</version>
</dependency>

但在部署时出现以下错误：

【问题讨论】：

你的 Neo4jConfiguration 类是什么样的？
刚刚发布在“更新 2”下。

标签： maven neo4j spring-data-neo4j-4 neo4j-ogm

【解决方案1】：

假设您使用的是 4.1.2 版

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-neo4j</artifactId>
    <version>4.1.2.RELEASE</version>
</dependency>

然后，添加 Bolt 驱动依赖

<dependency>
    <groupId>org.neo4j</groupId>
    <artifactId>neo4j-ogm-bolt-driver</artifactId>
    <version>2.0.3</version>
</dependency>

不应产生任何版本冲突。

以下是 Bolt 的最小 ogm.properties 文件示例：

driver=org.neo4j.ogm.drivers.bolt.driver.BoltDriver
URI=bolt://neo4j:password@localhost
encryption.level=NONE

编辑：我已经在https://github.com/neo4j-examples/sdn4-cineasts/tree/4.2 升级了cineasts 项目以使用SDN 4.2.0.M1 和Bolt 驱动程序。

并且4.1分支是基于SDN 4.1.2和OGM 2.0.3 https://github.com/neo4j-examples/sdn4-cineasts/tree/4.1

对于这两个分支，所有测试都通过并且http://localhost:8080/movies?q=matrix 不会产生异常。

请注意，SDN 4.1.2 和 OGM 2.0.4 存在问题。这已在 SDN 4.1.3-SNAPSHOT 中修复

【讨论】：

谢谢，但这无法部署，请参阅上面的更新。与此同时，我已经构建了原始的、未修改的 sdn4-cineasts 示例，但在注册和登录时出现“HTTP ERROR 405，问题访问/auth/denied。原因：不支持请求方法'POST'”错误。所以我怀疑我试图使用一个不起作用的例子。

【解决方案2】：

我已经得出结论，我无法让 Bolt 在 Spring 4.1.2.RELEASE 工作。我现在使用 HTTP 驱动程序没有问题。

请看我编辑的答案，我已经升级了cineasts依赖项
我在使用 4.1.2 和螺栓驱动器时遇到了同样的问题。让我们等待适当的解决方案。
