如何在android中使用logback？

问题描述 投票：0回答：1

我按照这篇文章设置了logback。

注意：我使用的是 

logback
，而不是 
logback-android

项目依赖：

implementation 'org.slf4j:slf4j-api:2.0.7'
implementation 'ch.qos.logback:logback-classic:1.4.7'
implementation 'ch.qos.logback:logback-core:1.4.7'

xml配置文件

app\src\main\resources\logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

    <appender name="Logcat"
        class="ch.qos.logback.classic.android.LogcatAppender">
        <encoder>
            <Pattern>%date %level %msg%n</Pattern>
        </encoder>
    </appender>

    <appender name="File" class="ch.qos.logback.core.FileAppender">
        <file>./log/test.log</file>
        <encoder>
            <pattern>%date %level %msg%n</pattern>
        </encoder>
    </appender>

    <root level="debug">
        <appender-ref ref="Logcat" />
        <appender-ref ref="File"/>
    </root>

</configuration>

然后像这样使用

logger
：

class MainActivity : ComponentActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    val logger = LoggerFactory.getLogger("qwdqwd")

    logger.debug("hello")

    setContent {
      AndroidcomposelatestTheme {
        // A surface container using the 'background' color from the theme
        Surface(modifier = Modifier.fillMaxSize(), color = MaterialTheme.colorScheme.background) {
          ArticleScreen2()
        }
      }
    }
  }
}

出现错误：

我错过了什么？

对于那些想要在 Android 中使用 Logback classic 并具有解决方案的人，因为 

Logback-android
已经过时了

第一步

添加打包选项，Logback classic 和 Logback core 都包含 INDEX.LIST 需要选择其一才能构建成功。

android {
    packagingOptions {
        pickFirst  'META-INF/INDEX.LIST'
    }
}

第二步

克隆 

ContextInitializer
然后在 
autoConfig()
替换下面的块代码

var versionStr = EnvUtil.logbackVersion()
    if (versionStr == null) {
        versionStr = CoreConstants.NA
    }

由

var versionStr = CoreConstants.NA // or any string you want

第三步

克隆 

LogbackServiceProvider
，然后替换为导入步骤 2 中克隆的 
ContextInitializer
，而不是 
Logback's ContextInitializer

最后一步

配置为让 SLF4j 选择您克隆的 

LogbackServiceProvider
，而不是默认的，方法是创建一个 resources/META-INF/services/org.slf4j.spi.SLF4JServiceProvider 文件，其中包含指向您克隆的 
LogbackServiceProvider
的值链接 - 详细信息参见图片
