java中的system.getproperty(String key)信息

星期五, 十二月 30th, 2011 | JAVA-and-J2EE | 没有评论

经常可以在程序中看到别人用System.getProperty(“user.dir”);这种信息,其实这个并不什么都是系统自带的属性;

可以查看java API 里 System 这个类里 getProperties 方法下有这样的说明:

java.vendor Java Runtime Environment vendor
java.vendor.url Java vendor URL
java.home Java installation directory
java.vm.specification.version Java Virtual Machine specification version
java.vm.specification.vendor Java Virtual Machine specification vendor
java.vm.specification.name Java Virtual Machine specification name
java.vm.version Java Virtual Machine implementation version
java.vm.vendor Java Virtual Machine implementation vendor
java.vm.name Java Virtual Machine implementation name
java.specification.version Java Runtime Environment specification version

Multiple paths in a system property value are separated by the path separator character of the platform.
