Question

我使用SDN4 Cineasts中的示例作为起点，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，我无法通过Bolt驱动程序编译或部署示例。（我打造一场战争，而不是一个罐子，所以如果这有任何不同，请告诉我们。）

有人可以确认添加此依赖项：

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

将失败，因为依赖项无法解决，并且使用任何高于2.0.0的版本号将因版本地狱而无法部署;或者请指出我的方式的错误？如果您这样做，您也可以将ogm.properties修改为如下所示（根据需要替换<your-username>和<your-password>）：

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>

但在部署时遇到以下错误：

Answer 1

Assuming you're using version 4.1.2

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

Then, adding the Bolt driver dependency

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

should not produce any version conflicts.

Here's an example of a minimal ogm.properties file for Bolt:

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

Edit: I've upgraded the cineasts project here https://github.com/neo4j-examples/sdn4-cineasts/tree/4.2 to work with SDN 4.2.0.M1 and the Bolt driver.

And the 4.1 branch is based on SDN 4.1.2 and OGM 2.0.3 https://github.com/neo4j-examples/sdn4-cineasts/tree/4.1

With both branches, all tests pass and http://localhost:8080/movies?q=matrix produce no exceptions.

Note that there is a problem with SDN 4.1.2 and OGM 2.0.4. This has been fixed in SDN 4.1.3-SNAPSHOT

Answer 2

我的结论是，我无法让Bolt在Spring 4.1.2.RELEASE上工作。我现在正在使用HTTP驱动程序而没有问题。

Spring Data + Neo4J + Bolt无法正常工作
