java的System.getProperty()方法可以获取的值

public static void main(String[] args) {
		System.out.println("java_version:" + System.getProperty("java.version"));//java运行时环境版本
		System.out.println("java_vendor:" + System.getProperty("java.vendor"));//java运行时环境供应商
		System.out.println("java_vendor_url:"+ System.getProperty("java.vendor.url"));//java供应商的url
		System.out.println("java_home:" + System.getProperty("java.home"));//java的安装目录
		System.out.println("java_vm_specification_version:"+ System.getProperty("java.vm.specification.version"));//java虚拟机规范版本
		System.out.println("java_vm_specification_vendor:"+ System.getProperty("java.vm.specification.vendor"));//java虚拟机规范供应商
		System.out.println("java_vm_specification_name:"+ System.getProperty("java.vm.specification.name"));//java虚拟机规范名称
		System.out.println("java_vm_version:"+ System.getProperty("java.vm.version"));//java虚拟机实现的版本
		System.out.println("java_vm_vendor:"+ System.getProperty("java.vm.vendor"));//java虚拟机实现的供应商
		System.out.println("java_vm_name:" + System.getProperty("java.vm.name"));//java虚拟机实现的名称
		System.out.println("java_specification_version:"+ System.getProperty("java.specification.version"));//java运行时环境规范的版本
		System.out.println("java_specification_vendor:"+ System.getProperty("java.specification.vendor"));//java运行时环境规范的供应商
		System.out.println("java_specification_name:" + System.getProperty("java.specification.name"));//java运行时环境规范的名称
		System.out.println("java_class_version:"+ System.getProperty("java.class.version"));//java类格式的版本号（也就是jdk1.7对应的版本）
		System.out.println("java_class_path:"+ System.getProperty("java.class.path"));//java类的路径，一般是java_home/bin
		System.out.println("java_library_path:" + System.getProperty("java.library.path"));//加载库时搜索的路径列表
		System.out.println("java_io_tmpdir:"+ System.getProperty("java.io.tmpdir"));//默认的临时文件路径
		System.out.println("java_compiler:"+ System.getProperty("java.compiler"));//要使用的jit编译器的名字		
		System.out.println("java_ext_dirs:"+ System.getProperty("java.ext.dirs"));//一个或多个扩展目录的路径		
		System.out.println("os_name:" + System.getProperty("os.name"));//操作系统的名称
		System.out.println("os_arch:" + System.getProperty("os.arch"));//操作系统的架构
		System.out.println("os_version:" + System.getProperty("os.version"));//操作系统的版本
		System.out.println("file_separator:"+ System.getProperty("file.separator"));//文件分隔符
		System.out.println("path_separator:"+ System.getProperty("path.separator"));//路径分隔符		
		System.out.println("line_separator:"+ System.getProperty("line.separator"));//行分隔符
		System.out.println("user_name:" + System.getProperty("user.name"));//用户的账户名称
		System.out.println("user_home:" + System.getProperty("user.home"));//用户的主目录
		System.out.println("user_dir:" + System.getProperty("user.dir"));//用户的当前工作目录
	}
