创建一个新的批处理文件(例如:openclass.bat)，并在文件中写入这一行:

java %~n1

然后将批处理文件放在system32文件夹中，找到你的Java类文件，右键单击，Properties, Open with…，然后找到你的批处理文件，选择它，这就是…

这对我很管用。

PS:当我关闭Java类时，我找不到关闭cmd窗口的方法。现在……

让我们保持简单。

下面是.cmd文件。

@echo off
rem this file is named echo_3params.cmd
echo %1
echo %2
echo %3
set v1=%1
set v2=%2
set v3=%3
echo v1 equals %v1%
echo v2 equals %v2%
echo v3 equals %v3%

下面是命令行中的3个调用。

C:\Users\joeco>echo_3params 1abc 2 def  3 ghi
1abc
2
def
v1 equals 1abc
v2 equals 2
v3 equals def

C:\Users\joeco>echo_3params 1abc "2 def"  "3 ghi"
1abc
"2 def"
"3 ghi"
v1 equals 1abc
v2 equals "2 def"
v3 equals "3 ghi"

C:\Users\joeco>echo_3params 1abc '2 def'  "3 ghi"
1abc
'2
def'
v1 equals 1abc
v2 equals '2
v3 equals def'

@ECHO OFF
:Loop
IF "%1"=="" GOTO Continue
SHIFT
GOTO Loop
:Continue

注意:如果“%1”==“”将导致问题，如果%1本身被括在引号中。

在这种情况下，使用IF[%1]==[]，或者仅在NT 4 (SP6)及以后版本中使用IF "%~1"==""。

FOR %%A IN (%*) DO (
    REM Now your batch file handles %%A instead of %1
    REM No need to use SHIFT anymore.
    ECHO %%A
)

这个循环遍历批处理参数(%*)，不管它们是否带引号，然后回显每个参数。

最近有个朋友问我这个问题，所以我想在这里发布一下我如何在批处理文件中处理命令行参数。

正如您将看到的，这种技术有一些开销，但它使我的批处理文件非常容易理解和快速实现。以及支持以下结构:

>template.bat [-f] [--flag] [--namedvalue value] arg1 [arg2][arg3][...]

它的jist包含:init、:parse和:main函数。

示例使用

>template.bat /?
test v1.23
This is a sample batch file template,
providing command-line arguments and flags.

USAGE:
test.bat [flags] "required argument" "optional argument"

/?, --help           shows this help
/v, --version        shows the version
/e, --verbose        shows detailed output
-f, --flag value     specifies a named parameter value

>template.bat          <- throws missing argument error
(same as /?, plus..)
****                                   ****
****    MISSING "REQUIRED ARGUMENT"    ****
****                                   ****

>template.bat -v
1.23

>template.bat --version
test v1.23
This is a sample batch file template,
providing command-line arguments and flags.

>template.bat -e arg1
**** DEBUG IS ON
UnNamedArgument:    "arg1"
UnNamedOptionalArg: not provided
NamedFlag:          not provided

>template.bat --flag "my flag" arg1 arg2
UnNamedArgument:    "arg1"
UnNamedOptionalArg: "arg2"
NamedFlag:          "my flag"

>template.bat --verbose "argument #1" --flag "my flag" second
**** DEBUG IS ON
UnNamedArgument:    "argument #1"
UnNamedOptionalArg: "second"
NamedFlag:          "my flag"
