Apache Ignite结构化日志记录

Question

我希望为Ignite启用结构化日志记录。Ignite在码头集装箱内运行。我启用了log4j2模块，并添加了一个试图使用<JsonTemplateLayout/>正如这里所描述的，但在日志中我得到了消息：

Console包含无效的元素或属性"JsonTemplateLayout"；

这可能是由于ignite内部没有可用的log4j布局模板json依赖关系造成的。有没有一种方法可以将依赖项添加到Ignite，或者有没有其他方法可以让结构化日志工作？

点火配置：

log4j2配置：

当将JAR添加到libs时(正如Stanislav在下面所建议的那样(，我更进一步，但也得到了一个错误(不是java人员，所以任何提示都非常感谢(：

解决方案

正如Stanislav Lukyanov(见公认答案(所建议的那样，解决方案是下载JAR并将其放在$IGNITE_HOME/libs下面。上面提到的错误是由版本不匹配引起的。拥有以下具有正确版本的JAR使其发挥作用：

• log4j-api-2.17.1.jar(默认值由点火分发提供(
• log4j-core-2.17.1.jar(默认值由ignite分发提供(
• 点火器-log4j2-13.0.jar(默认值由点火分配提供(
• log4j-layout-template-json-2.17.1.jar(已添加，不适用于2.18.x版本(

如果使用Maven运行Ignite，则需要向应用程序POM添加所需的依赖项，如文档中所述：

<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-layout-template-json</artifactId>
<version>2.18.0</version>
</dependency>

如果使用ZIP分发运行Ignite，则需要将依赖项下载为JAR，例如从这里下载，并将其添加到$IGNITE_HOME/libs中。
