jakarta-ee - catalina.bat 中的 JAVA_OPTS 语法

Question

我正在尝试通过在 catalina.bat 中添加 JAVA_OPTS 来增加 tomcat 内存，如下所示:

rem   TITLE           (Optional) Specify the title of Tomcat window. The default
rem                   TITLE is Tomcat if it's not specified.
rem                   Example (all one line)
rem                   set TITLE=Tomcat.Cluster#1.Server#1 [%DATE% %TIME%]
rem
rem
rem
rem $Id: catalina.bat 1146096 2011-07-13 15:20:43Z markt $
rem ---------------------------------------------------------------------------

JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 
-server -Xms1536m -Xmx1536m
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m 
-XX:MaxPermSize=512m -XX:+DisableExplicitGC 
-XX:UseConcMarkSweepGC 
-XX:CMSPermGenSweepingEnabled 
-XX:CMSClassUnloadingEnabled"

但在运行启动或关闭脚本时，我在 CMD 中遇到以下错误:

'JAVA_OPTS' is not recognized as an internal or external command,
operable program or batch file.
'-server' is not recognized as an internal or external command,
operable program or batch file.

请告诉我为什么要得到它们。

尝试:

set JAVA_OPTS=-Djava.awt.headless=true -Dfile.encoding=UTF-8 ^
-server -Xms1536m -Xmx1536m ^
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m ^
-XX:MaxPermSize=512m -XX:+DisableExplicitGC ^
-XX:+UseConcMarkSweepGC ^
-XX:+CMSClassUnloadingEnabled

• 您需要使用set命令设置环境变量。
• 如果您想在 Windows bat 文件中将一条命令拆分为多行，您需要在每行末尾添加一个 ^(脱字符号)。
• 无需引号。
