Open Liberty 22.0.0.6-beta提供了一个新的测试版功能（连同所有的GA功能），它提供了新的日志功能，将日志中的堆栈痕迹连接起来，使它们作为一个单一的日志事件输出。

Open Liberty22.0.0.6-beta包括以下测试版功能（以及所有GA功能）。、：

新的日志功能：将堆栈跟踪合并为一个单一的日志事件

当在Open Liberty中记录堆栈跟踪时，通常是来自应用程序的Throwable.printStackTrace() 调用，现在你可以把发出的堆栈跟踪作为一个单一的日志事件输出。如果你把你的日志转发到下游的第三方日志分析技术，如Elastic Logstash Kibana（ELK）栈，这个更新是有影响的。它影响到控制台输出、控制台日志、消息日志和跟踪日志。在这次更新之前，堆栈跟踪的每一行都被打印为一个单独的事件。

例子

没有加入堆栈跟踪的控制台输出：

这个新功能是通过配置引导属性、环境变量或通过server.xml 文件启用的。如果在所有这些选项中都有配置，那么配置的优先级是server.xml > 环境变量 > bootstrap属性。

配置

  • bootstrap.properties:
`com.ibm.ws.logging.stackJoin=true
  • server.env:
WLP_LOGGING_STACK_JOIN=true
  • server.xml:
<logging stackJoin="true" />

现在就试试吧

要尝试这些功能，只需更新你的构建工具，拉出Open Liberty所有测试版功能包，而不是主版本。该测试版适用于Java SE 18、Java SE 17、Java SE 11和Java SE 8。

如果你使用Maven，这里有坐标：

<dependency>
  <groupId>io.openliberty.beta</groupId>
  <artifactId>openliberty-runtime</artifactId>
  <version>22.0.0.6-beta</version>
  <type>pom</type>
</dependency>

或者对于Gradle：

dependencies {
    libertyRuntime group: 'io.openliberty.beta', name: 'openliberty-runtime', version: '[22.0.0.6-beta,)'
}

或者看一下我们的下载页面。
