Question

在我使用的普通Java应用程序中启用apache commons HttpClient的日志记录：

System.setProperty("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.SimpleLog");
System.setProperty("org.apache.commons.logging.simplelog.showdatetime", "true");
System.setProperty("org.apache.commons.logging.simplelog.log.httpclient.wire", "debug");
System.setProperty("org.apache.commons.logging.simplelog.log.org.apache.commons.httpclient", "debug");

但是在android上我没有看到LogCat中的日志。

我错过了什么吗？

Answer 1

忽略我之前的评论。我在org.apache.http日志页面上找到了解决方案。您的原始答案是指httpclient-3.x logging，最新版本的工作代码来自http-components logging

java.util.logging.Logger.getLogger("org.apache.http.wire").setLevel(java.util.logging.Level.FINEST);
java.util.logging.Logger.getLogger("org.apache.http.headers").setLevel(java.util.logging.Level.FINEST);

System.setProperty("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.SimpleLog");
System.setProperty("org.apache.commons.logging.simplelog.showdatetime", "true");
System.setProperty("org.apache.commons.logging.simplelog.log.httpclient.wire", "debug");
System.setProperty("org.apache.commons.logging.simplelog.log.org.apache.http", "debug");
System.setProperty("org.apache.commons.logging.simplelog.log.org.apache.http.headers", "debug");

和属性：

adb shell setprop log.tag.org.apache.http VERBOSE
adb shell setprop log.tag.org.apache.http.wire VERBOSE
adb shell setprop log.tag.org.apache.http.headers VERBOSE

区别在于日志标记名称。

这是一个解决方案（没有深入细节）

<强>控制台：

adb shell setprop log.tag.httpclient.wire.header VERBOSE
adb shell setprop log.tag.httpclient.wire.content VERBOSE

<强>代码：

java.util.logging.Logger.getLogger("httpclient.wire.header").setLevel(java.util.logging.Level.FINEST);
java.util.logging.Logger.getLogger("httpclient.wire.content").setLevel(java.util.logging.Level.FINEST);

<强>测试

java.util.logging.Logger.getLogger("httpclient.wire.content").log(java.util.logging.Level.CONFIG, "hola");

Answer 3

魔鬼在于细节。我正在运行2.3.3模拟器并使用它：

java.util.logging.Logger.getLogger("org.apache.http.wire").setLevel(java.util.logging.Level.FINEST);
java.util.logging.Logger.getLogger("org.apache.http.headers").setLevel(java.util.logging.Level.FINEST);

并在adb shell中

# setprop log.tag.org.apache.http.wire VERBOSE
# setprop log.tag.org.apache.http.headers VERBOSE

因此，日志说明符似乎不同。

你只需要使用

java.util.logging.Logger.getLogger(yourFullClassName).setLevel(java.util.logging.Level.All);

和

adb shell setprop log.tag.correspondingTag VERBOSE

Android使用此函数从类全名获取对应的标签：

public static String loggerNameToTag(String loggerName)
  {
    if (loggerName == null) {
      return "null";
    }

    int length = loggerName.length();
    if (length <= 23) {
      return loggerName;
    }

    int lastPeriod = loggerName.lastIndexOf(".");
    return length - (lastPeriod + 1) <= 23 ? loggerName.substring(lastPeriod + 1) : loggerName.substring(loggerName.length() - 23);
  }

所以例如，我想为“org.apache.http.impl.client.DefaultRequestDirector”类启用日志记录，请执行以下操作：

String clzName = "org.apache.http.impl.client.DefaultRequestDirector";
String newClzName = loggerNameToTag(clzName);
System.out.println("className:" + clzName + " tagName is " + newClzName);    //get tagName from class full name,and then it will be used in setprop
Logger jdkLogger = Logger.getLogger(clzName);
jdkLogger.setLevel(Level.ALL);
if (jdkLogger.isLoggable(Level.FINE))
{
        jdkLogger.log(Level.FINE, "jdk log msg");    
        jdkLogger.log(Level.Fine,"tagName is")
}

然后在adb shell中

setprop log.tag.DefaultRequestDirector VERBOSE
