将自定义logback配置添加到neo4j非托管扩展

标签： slf4j logback neo4j

我想为我的非托管扩展启用日志记录，到目前为止工作也很好（至少在我的单元测试中）。所以我写了一个logback.xml并将其包含在我的包中。当我使用将在动态创建的数据库运行单元测试（功能测试）时，一切正常，即我的日志记录定义得到识别，并且日志记录按预期工作。以下是日志的摘录，您可以在其中看到不同的日志：

但是，当我将扩展部署到我的独立服务器时，我在console.log中获得了以下日志条目：

=＆GT;所以我认为来自neo4j的logback配置的设置和myproject的logback配置中的设置都不会被注册，并且将使用回退配置（conf / logging.properties（？））。

现在我的问题是：是否可以通过非托管扩展集成自己的logback配置，还是需要调整默认的logging.properties？

3 个答案:

答案 0 :(得分：2)

您是否尝试在conf/custom-logback.xml中配置登录？ Neo4j捆绑了包含此内容的logback.xml。

答案 1 :(得分：0)

以下是我如何运作的方式：

  1. 从您的neo4j独立安装的neo4j-server jar中删除logback.xml（它位于/ usr / share / neo4j / system / lib /）
  2. 将您的logback.xml放在$ NEO4J_HOME / conf /
  3. 确保您在neo4j独立安装的整个类路径中仅部署了一个logback.xml - ＆gt;您可以通过查看$ NEO4J_HOME / data / log / console.log中的日志文件来查看此内容。
  4. 您可以将neo4j-server软件包中logback.xml的logback配置包含在$ NEO4J_HOME / conf /的logback.xml中

    5. 第3点和第4点是可选的

答案 2 :(得分：0)

另一种方法可能是重命名logback.xml。

这是尝试自行配置时遵循的初始化步骤：

  1. Logback尝试在类路径中查找名为logback.groovy的文件。
  2. 如果未找到此类文件，则logback会尝试查找名为的文件 类路径中的logback-test.xml。
  3. 如果找不到这样的文件，它会检查文件中的文件logback.xml 类路径。
  4. 如果找不到任何文件，则logback会自动配置自身 使用BasicConfigurator将导致日志记录输出 指向控制台。

    5. 如果将文件重命名为logback-test.xml，则最好不要使用包含的logback.xml。这也是您将这些设置文件用于测试的方式。

    唯一的缺点是，您不能再为测试使用不同的logback-test.xml。

    作为最后一个选项，你可以使用documentation中提到的classpath参数，如果你附上它：-Dlogback.configurationFile=/path/to/config.xml
