使用Logback.xml播放2.1和Neo4J WrappingNeoServer错误

XML 前端之家
前端之家收集整理的这篇文章主要介绍了使用Logback.xml播放2.1和Neo4J WrappingNeoServer错误，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
我有一个嵌入式neo4j服务器,管理控制台在Play 2.0.1应用程序中工作.我最近升级为与DeadBolt兼容的发布候选人,发现应用程序不再运行.

要启动服务器,我在执行以下操作：

graphDb = (GraphDatabaseAPI) new GraphDatabaseFactory()
                .newEmbeddedDatabaseBuilder(CONF_DBMeta_LOCATION)
                .setConfig(ShellSettings.remote_shell_enabled,"true")
                .newGraphDatabase();
        ServerConfigurator config;
        config = new ServerConfigurator(graphDb);
        // let the server endpoint be on a custom port

        srv = new WrappingNeoServerBootstrapper(graphDb,config);
        srv.start();

不幸的是,我得到：

> java.lang.RuntimeException:
> org.neo4j.kernel.lifecycle.LifecycleException: Component
> 'org.neo4j.kernel.logging.LogbackService@4c043845' Failed to
> initialize. Please see attached cause exception.

我已经尝试从添加了neo4j-server的Build.scala中删除slf4j和logback依赖关系,但无济于事.看来,neo4j正在加载错误的logback.xml.此外,如果我将notTransitive()添加到neo4j服务器依赖项,则启动时的logback.xml警告将消失.我想象,neo4j特定的logback.xml嵌入在jar中并导致问题.我看到的一个潜在解决方案是通过代码编写自定义配置,但我不确定如何做到这一点.有什么想法吗？作为参考,我在启动时收到以下错误：

EDIT1更多细节

我从play_2.10.jar中删除了logback.xml文件,并且在播放应用程序启动时不再收到来自logback的重复警告.

然后,我尝试将neo4j logback.xml和play2.1 logback.xml的内容放在我的播放项目根目录下的custom-logback.xml中.与Play.application()相同的路径path()也许这是neo4j接收的错误位置？

在检查依赖关系时,我有一个new4j服务器需要一个janino.此外,我没有看到罐子里有任何冲突,但也许我错过了一些事情.这是我从“播放依赖”的依赖关系层次：

https://gist.github.com/4559389

我还尝试将Play2.1维基上列出的默认配置复制到custom-logback.xml中,而不成功：

<configuration>

  <conversionRule conversionWord="coloredLevel" converterClass="play.api.Logger$ColoredLevel" />

  <appender name="FILE" class="ch.qos.logback.core.FileAppender">
     <file>${application.home}/logs/application.log</file>
     <encoder>
       <pattern>%date - [%level] - from %logger in %thread %n%message%n%xException%n</pattern>
     </encoder>
   </appender>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%coloredLevel %logger{15} - %message%n%xException{5}</pattern>
    </encoder>
  </appender>

  <logger name="play" level="INFO" />
  <logger name="application" level="INFO" />

  <root level="ERROR">
    <appender-ref ref="STDOUT" />
    <appender-ref ref="FILE" />
  </root>

</configuration>

编辑2

肯定似乎是logback依赖关系的一个问题. Neo4j取决于0.9.30,玩依赖于1.0.7看起来.我猜这些版本之间有一个api的变化,当图书馆被加载？janino？它找不到合适的方法.仍然不确定如何在logback.xml中正确指定在运行时选择正确的依赖关系.

图由yed sbt-dependency-graph生成.

关于Neo4j生命周期异常,因为Play 2.1的较新版本的logback与Neo4j不兼容.我碰到这个问题,最后只是把Play的logback覆盖到一个较旧的兼容版本,把它放在我的Build.scala的项目依赖项中： 
"ch.qos.logback" % "logback-core" % "1.0.3" force(),// this should override the Play version
"ch.qos.logback" % "logback-classic" % "1.0.3" force(),

为了很好的措施,我还尝试排除通过设置SBT的ivyXML参数被拉入的任何log4j传递依赖关系：

ivyXML :=
  <dependencies>
    <exclude module="log4j"/>
  </dependencies>

这显然是一个脆弱的修复,但至少对于Play 2.1-RC2,它似乎工作.我仍然有问题实际配置Neo4j的日志记录,所以我稍后尝试更新这个答案.

更新：由于我是新的回溯我有一个困难配置它与Play / Neo4j.为了防止Logback发生错误并将其淹没在状态消息中,我需要在我的Play应用程序的conf目录中放入一个名为custom-logback.xml的文件.我认为Neo4j日志记录配置需要这个.矿包含以下内容：

<included>
    <logger name="eu.mypackage" level="info">
    </logger>

    <logger name="org.neo4j" level="warn">
    </logger>

    <root level="warn">
    </root>
</included>

另外在我的conf目录中,我似乎需要一个名为logback.properties的文件(在我的例子中)只包含这一行：

CONSOLE_LEVEL=ERROR

(Logback专家,随时更正任何一个.)
