maven - spring boot 2.0 neo4j ogm 3.0兼容jetty版本

Question

我正在尝试将 spring boot 从 1.5 升级到 2.0，但遇到了 jetty 版本问题。我是 neo4j ogm 和 spring boot 的新手。

当我尝试运行测试用例时，它失败并出现以下错误。

    java.lang.NoClassDefFoundError: org/eclipse/jetty/server/SessionManager        at org.neo4j.server.CommunityNeoServer.createWebServer(CommunityNeoServer.java:90)        at org.neo4j.server.AbstractNeoServer.init(AbstractNeoServer.java:188)        at org.neo4j.server.AbstractNeoServer.start(AbstractNeoServer.java:204)        at org.neo4j.harness.internal.InProcessServerControls.start(InProcessServerControls.java:71)        at org.neo4j.harness.internal.AbstractInProcessServerBuilder.newServer(AbstractInProcessServerBuilder.java:151)        at org.neo4j.ogm.testutil.TestServer.startServer(TestServer.java:75)        at org.neo4j.ogm.testutil.TestServer.(TestServer.java:63)        at org.neo4j.ogm.testutil.TestServer.(TestServer.java:53)

and tried simply adding jetty.version referred here in this issue, Spring boot integration test fails with Neo4j.

<jetty.version>9.2.9.v20150224</jetty.version>

在 pom.xml 上添加以上内容时，测试用例单独通过正常，按预期工作。但无法构建应用程序并以下面的 jetty 错误告终。

[ERROR]   The project com.example:demo:0.0.1-SNAPSHOT (C:\code\Springboot2.0_Neo4jOGM_Sample\pom.xml) has 1 error[ERROR]     Non-resolvable import POM: Failure to find org.eclipse.jetty:jetty-bom:pom:9.2.9.v20150224 in https://repo.spring.io/milestone was cached in the local repository, resolution will not be reattempted until the update interval of spring-milestone has elapsed or updates are forced @ org.springframework.boot:spring-boot-dependencies:2.0.0.RELEASE, C:\Users\nkumar\.m2\repository\org\springframework\boot\spring-boot-dependencies\2.0.0.RELEASE\spring-boot-dependencies-2.0.0.RELEASE.pom, line 1652, column 25 -> [Help 2][ERROR] 

代码示例可以在这里看到， https://github.com/nkumarclm/springboot2.0_neo4jogm3.0/

只是想知道在使用时是否存在任何版本兼容性问题，或者是否有任何建议使用提供的 spring 和 neo4j ogm 版本使用 .cql 文件运行测试？

非常感谢。

Answer 1

Jetty 内部类 org.eclipse.jetty.server.SessionManager ，存在于 Eclipse Jetty 7.0.x 到 9.3.x 的所有版本。

http://search.maven.org/#search%7Cga%7C1%7Cfc%3A%22org.eclipse.jetty.server.SessionManager%22

类(class)org.eclipse.jetty.server.SessionManager在 9.4.x 中被删除，作为 session 处理的主要版本重构的一部分。

至于...

Non-resolvable import POM: Failure to find org.eclipse.jetty:jetty-bom:pom:9.2.9.v20150224 ...

jetty-bom artifact，作为一个概念，自 Jetty 9.3.19.v20170502 以来一直存在，处于各种不良和不受支持的状态，直到它最终在 Jetty 9.4.7.v20180619 中为 spring-boot 的用户改进。

让我们看看 github.com/nkumarclm/springboot2.0_neo4jogm3.0 的原始依赖树

(这是原始树，没有本地指定的版本)

从这里我们了解到父级 org.springframework.boot:spring-boot-starter-parent:2.0.0.RELEASE需要 org.eclipse.jetty:jetty-server:jar:9.4.8.v20171121 .

Note: Jetty versioning (since 1995) is <servlet_support>.<major_version>.<minor_version>

所以你有:

• spring-boot 需要 9.4.x 的 Jetty 主版本
• neo4jogm 需要 Jetty 主要版本 9.2.x

那是不相容的。

项目github.com/nkumarclm/springboot2.0_neo4jogm3.0无法按照其定义/配置的方式运行。看来应该升级 neo4jogm 以支持 Jetty 9.4.x，或者应该将 spring-boot 降级以支持 Jetty 9.2.x。

简而言之，您遇到的问题比仅仅选择正确版本的 Jetty 还要大。
