Passing system properties that contains spaces to Tomcat through JAVA_OPTS
提问by AlexBrand
I need to pass multiple system properties to Tomcat 6 through the JAVA_OPTS environment variable. I can't seem to pass system properties that contain spaces:
我需要通过 JAVA_OPTS 环境变量将多个系统属性传递给 Tomcat 6。我似乎无法传递包含空格的系统属性：
JRE_HOME=/root/jre1.6.0_34/ JAVA_OPTS="-DsysProp1=foo -DsysProp2=bar with spaces" ./catalina.sh run
Fails with:

I looked around on SO and the answers don't seem to help. Tried all of these with no success:
我环顾四周，答案似乎没有帮助。尝试了所有这些都没有成功：
JRE_HOME=/root/jre1.6.0_34/ JAVA_OPTS="-DsysProp1=foo -DsysProp2=\"bar with spaces\"" ./catalina.sh run
JRE_HOME=/root/jre1.6.0_34/ JAVA_OPTS='-DsysProp1=foo -DsysProp2="bar with spaces"' ./catalina.sh run
JRE_HOME=/root/jre1.6.0_34/ JAVA_OPTS='-DsysProp1=foo -DsysProp2=bar\ with\ spaces' ./catalina.sh run

As an alternative you could put the property settings into conf/catalina.propertiesinstead of using JAVA_OPTS. This is a standard java.util.Propertiesformat file so you don't need to quote anything, it simply takes everything before the first equals sign, colon or space as the property name and everything after that as the value:
作为替代方案，您可以将属性设置放入conf/catalina.properties而不是使用JAVA_OPTS. 这是一个标准java.util.Properties格式文件，因此您不需要引用任何内容，它只需将第一个等号、冒号或空格之前的所有内容作为属性名称，并将其后的所有内容作为值：
sysProp2=bar with spaces
If you can't (or would prefer not to) modify that file directly, you can copy it to another location, edit the copy, and then pass
如果您不能（或不想）直接修改该文件，您可以将其复制到另一个位置，编辑副本，然后通过
-Dcatalina.config=file:/path/to/copy/of/catalina.properties
in JAVA_OPTSto make it load your properties from there.
在JAVA_OPTS使它从那里加载性能。

Alright. Thanks for providing the link to the actual script.
Here is what catalina.shdoes:
好吧。感谢您提供指向实际脚本的链接。这是catalina.sh它的作用：
exec "$_RUNJAVA" "$LOGGING_CONFIG" $JAVA_OPTS $CATALINA_OPTS # ... more stuff
So it is going to be split by spaces no matter what you do. There is no way to fix that without changing catalina.shfile.
所以无论你做什么，它都会被空格分割。如果不更改catalina.sh文件，则无法解决此问题 。
