Intellij IDEA系列教材 （三）- 基础 - 配置文件位置

步骤1:关于配置文件的位置
步骤2:关闭IDEA
步骤3:打开idea.properties
步骤4:修改配置位置
步骤5:再次启动IDEA

步骤 1 : 关于配置文件的位置

一旦开始使用IDEA之后，就需要做很多的配置相关工作，使得IDEA越来越符合你的个人习惯，让你使用起来得心应手。
而这些配置信息，都保存在C盘，比如我的就会默认保存在如图所示的位置

C:\Documents and Settings\Administrator\.IntelliJIdea2017.

2

而默认放在C盘是不好的习惯，一旦重装系统之后，所有的配置信息都丢失了，又要全部重头来过，所以本知识点讲解如何配置在其他盘下面

步骤 2 : 关闭IDEA

首先关闭已经打开的IDEA

步骤 3 : 打开idea.properties

IDEA的配置信息存放在idea.properties，如图所示，我的位置是在：

D:\software\IntelliJ IDEA 

2017.2

\bin\idea.properties

步骤 4 : 修改配置位置

如图所示，需要修改这两个位置。（注意要把前面的#去掉，否则就处于注释状态）

我是修改在了d:/software/.IntelliJIdea这个目录下，修改不放心的同学，可以复制使用我贴上来的idea.properties

# Use ${idea.home.path} macro to specify location relative to IDE installation home.

# Use ${xxx} where xxx is any Java property (including defined in previous lines of this file) to refer to its value.

# Note for Windows users: please make sure you're using forward slashes (e.g. c:/idea/system).

#---------------------------------------------------------------------

# Uncomment this option if you want to customize path to IDE config folder. Make sure you're using forward slashes.

#---------------------------------------------------------------------

idea.config.path=d:/software/.IntelliJIdea/config

#---------------------------------------------------------------------

# Uncomment this option if you want to customize path to IDE system folder. Make sure you're using forward slashes.

#---------------------------------------------------------------------

idea.system.path=d:/software/.IntelliJIdea/system

#---------------------------------------------------------------------

# Uncomment this option if you want to customize path to user installed plugins folder. Make sure you're using forward slashes.

#---------------------------------------------------------------------

# idea.plugins.path=${idea.config.path}/plugins

#---------------------------------------------------------------------

# Uncomment this option if you want to customize path to IDE logs folder. Make sure you're using forward slashes.

#---------------------------------------------------------------------

# idea.log.path=${idea.system.path}/log

#---------------------------------------------------------------------

# Maximum file size (kilobytes) IDE should provide code assistance for.

# The larger file is the slower its editor works and higher overall system memory requirements are

# if code assistance is enabled. Remove this property or set to very large number if you need

# code assistance for any files available regardless their size.

#---------------------------------------------------------------------

idea.max.intellisense.filesize=2500

#---------------------------------------------------------------------

# Maximum file size (kilobytes) IDE is able to open.

#---------------------------------------------------------------------

idea.max.content.load.filesize=20000

#---------------------------------------------------------------------

# This option controls console cyclic buffer: keeps the console output size not higher than the specified buffer size (Kb).

# Older lines are deleted. In order to disable cycle buffer use idea.cycle.buffer.size=disabled

#---------------------------------------------------------------------

idea.cycle.buffer.size=1024

#---------------------------------------------------------------------

# Configure if a special launcher should be used when running processes from within IDE.

# Using Launcher enables "soft exit" and "thread dump" features

#---------------------------------------------------------------------

idea.no.launcher=false

#---------------------------------------------------------------------

# To avoid too long classpath

#---------------------------------------------------------------------

idea.dynamic.classpath=false

#---------------------------------------------------------------------

# Uncomment this property to prevent IDE from throwing ProcessCanceledException when user activity

# detected. This option is only useful for plugin developers, while debugging PSI related activities

# performed in background error analysis thread.

# DO NOT UNCOMMENT THIS UNLESS YOU'RE DEBUGGING IDE ITSELF. Significant slowdowns and lockups will happen otherwise.

#---------------------------------------------------------------------

#idea.ProcessCanceledException=disabled

#---------------------------------------------------------------------

# There are two possible values of idea.popup.weight property: "heavy" and "medium".

# If you have WM configured as "Focus follows mouse with Auto Raise" then you have to

# set this property to "medium". It prevents problems with popup menus on some

# configurations.

#---------------------------------------------------------------------

idea.popup.weight=heavy

#---------------------------------------------------------------------

# Removing this property may lead to editor performance degradation under Windows.

#---------------------------------------------------------------------

sun.java2d.d3d=false

#---------------------------------------------------------------------

# Set swing.bufferPerWindow=false to workaround a slow scrolling in JDK6 (see IDEA-35883),

# But this may lead to performance degradation in JDK8, because it disables a double buffering,

# which is needed to eliminate tearing on blit-accelerated scrolling and to restore

# a frame buffer content without the usual repainting, even when the EDT is blocked.

#---------------------------------------------------------------------

swing.bufferPerWindow=true

#---------------------------------------------------------------------

# Removing this property may lead to editor performance degradation under X Window.

#---------------------------------------------------------------------

sun.java2d.pmoffscreen=false

#---------------------------------------------------------------------

# Enables HiDPI support in JBRE

#---------------------------------------------------------------------

sun.java2d.uiScale.enabled=true

#---------------------------------------------------------------------

# Applicable to the Swing text components displaying HTML (except JEditorPane).

# Rebases CSS size map depending on the component's font size to let relative

# font size values (smaller, larger) scale properly. JBRE only.

#---------------------------------------------------------------------

javax.swing.rebaseCssSizeMap=true

#---------------------------------------------------------------------

# Workaround to avoid long hangs while accessing clipboard under Mac OS X.

#---------------------------------------------------------------------

#ide.mac.useNativeClipboard=True

#---------------------------------------------------------------------

# Maximum size (kilobytes) IDEA will load for showing past file contents -

# in Show Diff or when calculating Digest Diff

#---------------------------------------------------------------------

#idea.max.vcs.loaded.size.kb=20480

#---------------------------------------------------------------------

# IDEA file chooser peeks inside directories to detect whether they contain a valid project

# (to mark such directories with a corresponding icon).

# Uncommenting the option prevents this behavior outside of user home directory.

#---------------------------------------------------------------------

#idea.chooser.lookup.for.project.dirs=false

#-----------------------------------------------------------------------

# Experimental option that does a number of things to make truly smooth scrolling possible:

#

# * Enables hardware-accelerated scrolling.

#     Blit-acceleration copies as much of the rendered area as possible and then repaints only newly exposed region.

#     This helps to improve scrolling performance and to reduce CPU usage (especially if drawing is compute-intensive).

#

# * Enables "true double buffering".

#     True double buffering is needed to eliminate tearing on blit-accelerated scrolling and to restore

#     frame buffer content without the usual repainting, even when the EDT is blocked.

#

# * Adds "idea.true.smooth.scrolling.debug" option.

#     Checks whether blit-accelerated scrolling is feasible, and if so, checks whether true double buffering is available.

#

# * Enables handling of high-precision mouse wheel events.

#     Although Java 7 introduced MouseWheelEven.getPreciseWheelRotation() method, JScrollPane doesn't use it so far.

#     Depends on the Editor / General / Smooth Scrolling setting, remote desktop detection and power save mode state.

#     Ideally, we need to patch the runtime (on Windows, Linux and Mac OS) to improve handling of the fine-grained input data.

#     This feature can be toggled via "idea.true.smooth.scrolling.high.precision" option.

#

# * Enables handling of pixel-perfect scrolling events.

#     Currently this mode is available only under Mac OS with JetBrains Runtime.

#     This feature can be toggled via "idea.true.smooth.scrolling.pixel.perfect" option.

#

# * Enables interpolation of scrolling input (scrollbar, mouse wheel, touchpad, keys, etc).

#     Smooths input which lacks both spatial and temporal resolution, performs the rendering asynchronously.

#     Depends on the Editor / General / Smooth Scrolling setting, remote desktop detection and power save mode state.

#     The feature can be tweaked using the following options:

#       "idea.true.smooth.scrolling.interpolation" - the main switch

#       "idea.true.smooth.scrolling.interpolation.scrollbar" - scrollbar interpolation

#       "idea.true.smooth.scrolling.interpolation.scrollbar.delay" - initial delay for scrollbar interpolation (ms)

#       "idea.true.smooth.scrolling.interpolation.mouse.wheel" - mouse wheel / touchpad interpolation

#       "idea.true.smooth.scrolling.interpolation.mouse.wheel.delay.min" - minimum initial delay for mouse wheel interpolation (ms)

#       "idea.true.smooth.scrolling.interpolation.mouse.wheel.delay.max" - maximum initial delay for mouse wheel interpolation (ms)

#       "idea.true.smooth.scrolling.interpolation.precision.touchpad" - precision touchpad interpolation

#       "idea.true.smooth.scrolling.interpolation.precision.touchpad.delay" - initial delay for precision touchpad interpolation (ms)

#       "idea.true.smooth.scrolling.interpolation.other" - interpolation of other input sources

#       "idea.true.smooth.scrolling.interpolation.other.delay" - initial delay for other input source interpolation (ms)

#

# * Adds on-demand horizontal scrollbar in editor.

#     The horizontal scrollbar is shown only when it's actually needed for currently visible content.

#     This helps to save editor space and to prevent occasional horizontal "jitter" on vertical touchpad scrolling.

#     This feature can be toggled via "idea.true.smooth.scrolling.dynamic.scrollbars" option.

#-----------------------------------------------------------------------

#idea.true.smooth.scrolling=true

#---------------------------------------------------------------------

# IDEA can copy library .jar files to prevent their locking.

# By default this behavior is enabled on Windows and disabled on other platforms.

# Uncomment this property to override.

#---------------------------------------------------------------------

# idea.jars.nocopy=false

#---------------------------------------------------------------------

# The VM option value to be used to start a JVM in debug mode.

# Some JREs define it in a different way (-XXdebug in Oracle VM)

#---------------------------------------------------------------------

idea.xdebug.key=-Xdebug

#-----------------------------------------------------------------------

# Change to 'enabled' if you want to receive instant visual notifications

# about fatal errors that happen to an IDE or plugins installed.

#-----------------------------------------------------------------------

idea.fatal.error.notification=disabled

步骤 5 : 再次启动IDEA

再次启动后，就可以发现配置信息都保存在d:\software.IntelljIIdea下了，这样即便是重装了系统，相关信息也不会丢失了。
