java获取jdk、系统、服务器等信息
1、获取jdk信息System.out.println(System.getProperty("java.version")); System.out.println(System.getProperty("java.vendor")); System.out.println(System.getProperty("java.vendor.url")); System.out.println(System.getProperty("java.home")); System.out.println(System.getProperty("java.vm.specification.version")); System.out.println(System.getProperty("java.vm.specification.vendor")); System.out.println(System.getProperty("java.vm.specification.name")); System.out.println(System.getProperty("java.vm.version")); System.out.println(System.getProperty("java.vm.vendor")); System.out.println(System.getProperty("java.vm.name")); System.out.println(System.getProperty("java.specification.version")); System.out.println(System.getProperty("java.specification.vendor")); System.out.println(System.getProperty("java.specification.name")); System.out.println(System.getProperty("java.class.version")); System.out.println(System.getProperty("java.class.path")); System.out.println(System.getProperty("java.library.path")); System.out.println(System.getProperty("java.io.tmpdir")); System.out.println(System.getProperty("java.compiler")); System.out.println(System.getProperty("java.ext.dirs"));
2、获取系统信息
System.out.println(System.getProperty("os.name")); System.out.println(System.getProperty("os.arch")); System.out.println(System.getProperty("os.version")); System.out.println(System.getProperty("file.separator")); System.out.println(System.getProperty("path.separator")); System.out.println(System.getProperty("line.separator")); System.out.println(System.getProperty("user.name")); System.out.println(System.getProperty("user.home")); System.out.println(System.getProperty("user.dir"));
2、获取Tomcat的版本
jsp中使用
<%= application.getServerInfo() %>
