在我的项目中, 我从命令窗口中调用 java 程序。 我有一个像下面一样的蝙蝠文件。 我在测试课中扔了一个运行时间例外。 在“%% export /b 1 ” 中, 所有命令都会跳过“% JAVA_ HOMEinjava” - cp “ bin/” 测试% RUN_ ARGS% 出口/b 1 ” 。
谁能告诉我"出口/B1"是什么意思?
@echo off
setlocal
set RUN_ARGS=%*
"%JAVA_HOME%injava" -cp "bin/" Test %RUN_ARGS% || exit /b 1
echo %RUN_ARGS%
dir
endlocal
exit /b 0
exit /B exits the batch file without exiting the command window. In other words, it leaves the command window open after your java process exits so you can review any output. the | is a pipe operator, it passes the output of the java command as input to the exit command.
双管 () 用于有条件地执行命令。 只有在向左返回一个大于零的错误级别时才执行右侧的命令 。
