application.getMajorVersion() - 2
application.getMimeType("txt") - null
application.getServerInfo() - Apache Tomcat/5.0.30
application.getServletContextName() - null
application.getContext()
config - javax.servlet.ServletConfig
config.getServletName() - jsp
config.getServletContext()
pageContext - javax.servlet.jsp.PageContext
pageContext.getRequest()
pageContext.getResponse()
pageContext.getServletConfig()
pageContext.getServletContext()
pageContext.getException()
pageContext.getSession()
pageContext.getOut()

request.getLocalAddr() - 127.0.0.1
request.getServletPath() - /jsp/test.jsp
request.getContextPath() - /123
request.getLocalName() - 127.0.0.1
request.getLocalPort() - 80
request.getPathInfo() - null
request.getProtocol() - HTTP/1.1
request.getQueryString() - null
request.getRemoteAddr() - 127.0.0.1
request.getRemoteHost() - 127.0.0.1

request.getRequestURI() - /123/jsp/test.jsp
request.getRequestURL() -
session - javax.servlet.http.HttpSession
session.getServletContext()
注:
中使用以下方法
request.getServletPath() :返回request的请求路径的相对于应用程序的相对路径
request.getContextPath()返回应用程序上下文相对路径
this.getRealPath(String str)返回UIL中str对应于本地磁盘的绝对路径
request.getLocalAddr() 返回服务器IP地址
