在Maven Jetty 7插件中启用调试日志记录（maven配置jetty及启动）

在Maven Jetty 7插件中启用调试日志记录（maven配置jetty及启动）

我正在mvn jetty:run使用最新的jetty插件通过简单的Java运行webapp
，但似乎无法找到一种方法来告诉jetty将DEBUG消息输出到控制台（对于嵌入式jetty实例，而不是插件本身）。当前仅输出WARN和INFO消息。我尝试设置-DDEBUG和-DVERBOSE，但是他们什么也没做。我已经看过文档了，但是似乎没有涵盖。

小编典典

更新： 好的，我终于把事情做好了，这就是我所做的。

我的理解是，由于Jetty 7使用JSP 2.1引擎，所以即使对于JSP引擎，Jetty
7也不依赖于特定的日志记录框架。因此，您可以使用任何日志记录框架。在这里，我将使用logback。

首先logback-classic在插件中添加依赖项，并将logback.configurationFile系统属性设置为指向配置文件：

<project>  ...  <build>    ...    <plugins>      <plugin>        <groupId>org.mortbay.jetty</groupId>        <artifactId>jetty-maven-plugin</artifactId>        <version>7.0.0.pre5</version>        <configuration>          <systemProperties>            <systemProperty>              <name>logback.configurationFile</name>              <value>./src/etc/logback.xml</value>            </systemProperty>          </systemProperties>        </configuration>        <dependencies>          <dependency>            <groupId>ch.qos.logback</groupId>            <artifactId>logback-classic</artifactId>            <version>0.9.15</version>          </dependency>        </dependencies>      </plugin>      ...    </plugins>  </build>  ...</project>

然后添加一个src/etc/logback.xml配置文件。下面是最小配置：

<configuration>  <appender name="STDOUT">    <layout>      <Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</Pattern>    </layout>  </appender>  <root level="debug">    <appender-ref ref="STDOUT"/>  </root></configuration>

使用此设置，jetty将输出DEBUG消息：

$ mvn码头：运行...00：31：33.089 [main]调试org.mortbay.log-启动DefaultHandler @ 145e5a600：31：33.089 [main]调试org.mortbay.log-已启动DefaultHandler @ 145e5a600：31：33.105 [main]调试org.mortbay.log-开始RequestLogHandler @ 1e8076100：31：33.106 [main]调试org.mortbay.log-已启动RequestLogHandler @ 1e8076100：31：33.106 [main]调试org.mortbay.log-启动HandlerCollection @ 148554200：31：33.106 [main]调试org.mortbay.log-启动HandlerCollection @ 148554200：31：33.106 [main]调试org.mortbay.log-开始org.mortbay.jetty.Server@a010ba00：31：33.174 [main]调试org.mortbay.log-开始org.mortbay.jetty.nio.SelectChannelConnector$1@ee21f500：31：33.216 [main] INFO org.mortbay.log-已启动SelectChannelConnector@0.0.0.0：808000：31：33.217 [main]调试org.mortbay.log-已启动SelectChannelConnector@0.0.0.0：808000：31：33.217 [main]调试org.mortbay.log-开始org.mortbay.jetty.Server@a010ba[INFO]启动了Jetty服务器

android – 启用调试日志记录firebase分析

android – 启用调试日志记录firebase分析

我正在尝试为Android Studio中的Firebase分析启用调试日志记录.我已经尝试按照此处的说明操作,仍然看不到我期望的日志：https://firebase.google.com/docs/analytics/android/events#log_events

enter image description here

当我在Android Studio的终端中运行链接中所描述的命令(并在上面显示)时,这是我看到的输出：

--------- beginning of system
--------- beginning of crash
--------- beginning of main
05-19 20:14:12.794 I/FA      ( 3083): App measurement is starting up, version: 9080
05-19 20:14:12.794 I/FA      ( 3083): To enable debug logging run: adb shell setprop log.tag.FA VERBOSE

这就是logcat中Android Monitor选项卡中显示的内容：

05-19 20:14:12.794 3083-3083/com.nick.app I/FA: App measurement is starting up, version: 9080
05-19 20:14:12.794 3083-3083/com.nick.app I/FA: To enable debug logging run: adb shell setprop log.tag.FA VERBOSE

我期望看到的是指示我记录的各种“事件”被正确记录.我在firebase开发者控制台中看到过它们,这让我相信我已经正确地实现了它们,我想更快地了解测试目的.

需要采取哪些步骤才能正确查看firebase分析调试日志？

解决方法:

确保运行adb shell setprop log.tag.FA VERBOSE,然后重新启动应用程序.启用日志仅适用于将来的日志.如果您有多个设备或模拟器连接到计算机,您可能需要告诉adb您要为其设置属性.您可以使用adb shell getprop读取当前的adb属性.您应该看到log.tag.FA属性设置为VERBOSE.设置log.tag.FA属性后,它将一直存在,直到您重新启动设备,因此您只需在设备重新启动后执行此操作一次.

我测试了以下脚本，在我这边，参数值在日志中正常显示。您是在模板文件中为参数设置默认值还是将其传递给管道yaml中的参数？

c – 为什么这个非常简单的Makefile产生如此多的调试日志记录？

c – 为什么这个非常简单的Makefile产生如此多的调试日志记录？

我正在学习Makefiles并决定写下我的第一个练习.我有一个包含两个文件的目录： 

Makefile  makefile.cpp

这是makefile.cpp(惊喜！)：

#include <iostream>

int main() {
  std::cout << "Hello World!\n";
  return 0;
}

这是Makefile：

CC = g++
FILES = makefile.cpp
OUT_EXE = makefileout

build: $(FILES)
    $(CC) -o $(OUT_EXE) $(FILES)

然后我运行make -d并得到一个很长的日志：

我的问题是：我做错了吗？为什么这么简单的例子会产生如此多的日志？

此外,即使源代码早于最新的make,我的Makefile似乎总是重新编译对象代码.换句话说,我从未见过这样的信息：“没有什么可做的.”

解决方法

我将解决编辑问题：

my Makefile always seems to recompile the object code even if the
source code is older than the latest make

在这个答案.

考虑你的Makefile：

CC = g++
FILES = makefile.cpp
OUT_EXE = makefileout

build: $(FILES)
    $(CC) -o $(OUT_EXE) $(FILES)

这里唯一的目标是构建,这是永远不会构造的东西(这就是为什么你每次都看到编译的原因).对此最简单的解决方法应该是：

CC = g++
FILES = makefile.cpp
OUT_EXE = makefileout

${OUT_EXE}: $(FILES)
    $(CC) -o $(OUT_EXE) $(FILES)

使用新规则make将检查makefileout而不是build,从而提供预期的行为.

如果您想进行更多实验,可以使用Makefile发出以下命令：

rm -f makefileout
touch build
make

你会发现即使可执行文件不存在,make也不会编译它.我告诉你为什么(一个简单的)练习的问题.
