问题描述

我受到另一个问题的启发:最佳实践使用 Java 系统属性

我目前正在寻找 Java 系统属性和可能值的完整列表.我正在研究一个简单的类来简化它们的使用(如果你有兴趣，获取源代码 和 背景信息(我的博客)).通过这个课程，我尝试提供以下内容:

  • 对 Java 系统属性的简单且一致的访问(无字符串常量)
  • 完整可用属性及其可能值的文档——在我的 IDE 中(即自动完成、内联 Javadoc)
  • 修复返回值和/或命名不一致的问题
  • 确保 java.io.tmpdir 存在——实际上这是我做这一切的主要原因:)

要获得完整的文档和可用属性的完整列表(即使是那些可用性严重依赖于 JVM 的属性)，我希望您下载源代码，运行它并发布您的结果.我将相应地更新该类并使其在给定位置可用.希望它能让你们中的一些人的生活变得轻松:)

我不是在寻找 System.getProperties() 或我系统上可用的所有属性.我正在尝试创建一个完整的系统属性列表——即使是那些与供应商、jvm 或版本相关的——那些不能保证存在并且其文档稀疏或难以找到的.像

这样的属性
  • sun.desktop(仅限 Linux，例如gnome")，
  • awt.toolkit(仅限 Mac，例如 apple.awt.CToolkit)
  • sun.cpu.endian(仅限 Sun JVM)
  • ...

我希望让其他人运行我的代码并发布他们的结果，以便以易于使用的 Java 枚举的形式编译一个综合列表(包含大量的属性及其可能值的文档)，例如:

String file = SystemProperty.JAVA_IO_TMPDIR + "file.txt";

代替

String tmp = System.getProperty("java.io.tmpdir");如果 (!tmp.endsWith(File.separator)tmp += File.separator;新文件(tmp).mkdirs();//确保 tmp 存在字符串文件 = tmp + "file.txt";

所以请运行该代码并发布您的发现.这是一个让您入门的简单脚本:

#!/bin/bash# 下载并运行# 你真的应该先看看代码，因为你不能确定# 我是一个值得信赖的人 ;)wget -N http://techblog.molindo.at/files/SystemProperty.javajavac SystemProperty.javajava系统属性

(我知道这不是一个真正的问题，而是一个众包问题.我希望没有人介意)

赏金:

由于此问题没有正确答案，因此将奖励发现最多新系统属性的人.提示:在 JVM 之上测试非标准 JVM(J2ME、Android、GCJ、OpenJDK、Apache Harmony 等)和通用语言(Groovy、Scala、JRuby 等)应该特别有效.

现任领导:

  1. rsp 19 个已发现的属性
  2. 鲍里斯14 个已发现的属性
  3. JoaEbert 8 发现的属性
  4. Suraj Chandran 1 个发现的财产

顺便说一句，我计划将最终结果作为 Maven 工件发布，并在我有足够的输入后将其上传到中央存储库.

更新:公共存储库，终于

SystemProperty.java 现在在 GitHub 上可用，作为 molindo-utils 项目的一部分一>.molindo-utils 目前可用 1.0-SNAPSHOT 通过 Sonatype 的 OSS 存储库.一旦准备好发布，它也会同步到 Maven 中心.

I've been inspired by another question: Best Practice for Using Java System Properties

I'm currently looking for a complete list of Java system properties and possible values. I'm working on a simple class to simplify use of them (If you're interested, get the source and background info (my blog)). With this class, I try to provide the following:

  • simple and consistent access to Java system properties (no String constants)
  • full documentation of available properties and their possible values – within my IDE (i.e. auto-completion, inline Javadoc)
  • fix inconsistencies in returned values and/or naming
  • make sure that java.io.tmpdir exists – acutally that’s the main reason why I’m doing all this :)

To get full documentation and a complete list of available properties (even those where availability is heavily JVM-dependent), I'd like you to download the source, run it and post your results. I'll update the class accordingly and keep it available at the given location. Hopefully, it will ease live of some of you out there :)

Edit:

I'm not looking for standard properties as described by System.getProperties() or all properties that are available on my system. I'm trying to create a comprehensive list of system properties - even those that are vendor, jvm or version related - those that aren't guaranteed to exist and whose documentation is sparse or hard to find. Properties like

  • sun.desktop (Linux only, e.g. "gnome"),
  • awt.toolkit (Mac only, e.g. apple.awt.CToolkit)
  • sun.cpu.endian (Sun JVMs only)
  • ...

I'd love to get others to run my code and post their results in order to compile a comprehensive list (with extensive documentation of properties and their possible values) in the form of a Java enum that's easy to use e.g.:

String file = SystemProperty.JAVA_IO_TMPDIR + "file.txt";

instead of

String tmp = System.getProperty("java.io.tmpdir");
if (!tmp.endsWith(File.separator)
    tmp += File.separator;
new File(tmp).mkdirs(); // make sure tmp exists
String file = tmp + "file.txt";

So please run that code and post your findings. Here is a simple script to get you started:

#!/bin/bash
# download and run
# you should really look at the code first, as you can't be sure
# that I'm a trustworthy guy ;)
wget -N http://techblog.molindo.at/files/SystemProperty.java
javac SystemProperty.java
java SystemProperty

(I know this isn't a real question but rather a crowd sourcing thing. I hope nobody minds)

Bounty:

As there is no correct answer to this question, the bounty will be awarded to the person who discovers most new system properties. As a hint: testing non-standard JVMs (J2ME, Android, GCJ, OpenJDK, Apache Harmony, ...) and common languages on top of the JVM (Groovy, Scala, JRuby, ..) should be especially yielding.

Current leaders:

  1. rsp 19 discovered properties
  2. Boris 14 discovered properties
  3. Joa Ebert 8 discovered properties
  4. Suraj Chandran 1 discovered property

Btw, I'm planning to release the final result as a Maven artifact and upload it to the central repository as soon as I have enough input.

UPDATE: Public Repository, finally

SystemProperty.java is now available on GitHub, as part of the molindo-utils project. molindo-utils is currently available as 1.0-SNAPSHOT through Sonatype's OSS repository. As soon as it's ready for release, it will be synchronized to Maven central as well.
