将 Logback appender 与标准 App Engine Java 11 一起用于 Cloud Logging 时出现 NullPointerException

[英]NullPointerException when using Logback appender for Cloud Logging with standard App Engine Java 11

问题描述

我已按照本指南使用 logback appender 将我的应用程序日志写入 Cloud Logging。 我的应用程序是一个 Jetty 网络服务器，我通过将以下入口点添加到我的 app.yaml 文件来运行它：

runtime: java11
entrypoint: 'java -cp "*" com.jettymain.Main webapp.war'

这是在 pom 文件中添加的依赖项。

<dependency>
        <groupId>com.google.cloud</groupId>
        <artifactId>google-cloud-logging-logback</artifactId>
        <version>0.122.1-alpha</version>
</dependency>

这是位于 src\\main\\resources 中的 logback.xml 文件：

<!-- [START logging_logback_config] -->
<configuration>
  <appender name="CLOUD" class="com.google.cloud.logging.logback.LoggingAppender">
    <log>application.log</log> <!-- Optional : default java.log -->
    <resourceType>gae_app</resourceType> <!-- Optional : default: auto-detected, fallback: global -->
    <flushLevel>WARN</flushLevel> <!-- Optional : default ERROR -->
  </appender>

  <root level="info">
    <appender-ref ref="CLOUD" />
  </root>
</configuration>
<!-- [END logging_logback_config] -->

这就是我使用记录器的方式：

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Quickstart {
  private static final Logger logger = LoggerFactory.getLogger(Quickstart.class);

  public static void main(String[] args) {
    logger.info("Logging INFO with Logback");
    logger.error("Logging ERROR with Logback");
  }
}

当我运行应用程序时，这是我得到的异常：

解决这个问题最简单的方法是构建一个简单的hello world应用程序，并尝试在请求日志下实现分组。

请参阅链接以实现此目的。

以下是如何在请求日志下对日志进行分组的解决方法：

在主文件SpringbootApplication.java 中：

有以下方法：

 @GetMapping("/")
public String hello(@RequestHeader(value = "x-cloud-trace-context") String traceId) {
String[] parts = traceId.split("/"); 
String trace = parts[0];  
MDC.put("logging.googleapis.trace", String.format("projects/%s/traces/%s", "YOUR_PROJECT_ID", trace));
logger.info("Logging INFO with Logback" + trace);
logger.error("Logging ERROR with Logback" + trace);  
return trace;

}

我通过使用 spring mvc 注释并在 MDC 中设置跟踪的第一部分来获取 x-cloud-trace-context 标头。 您可以保留此方法或使用 http 请求过滤器将这部分抽象出来，而不是在每个方法中都这样做。 还要确保将“YOUR_PROJECT_ID”替换为您的实际项目 ID。

MDC 属性然后由 logback.xml 文件中定义的 TraceLoggingEventEnhancer 获取，然后确保所有日志都显示在您的请求日志下。

注意：Google 已提供了此处提到的修复程序。 确保您使用的是最新版本的 google-cloud-core。
