Tomcat 路径问题之web 头像

我的tomcat放到d盘下，项目名称为project,则：
System.out.println(request.getRealPath(""));
System.out.println(request.getContextPath());
      System.out.println(getServlet().getServletContext().getRealPath("/"));

    依次输出：
    d:\apache-tomcat-5.5.26\webapps\project
    /project
    d:\apache-tomcat-5.5.26\webapps\project\


在jsp页面中直接使用
   ${pageContext.request.contextPath}就可以找到
        C:\apache-tomcat-5.5.26\webapps\project\
只用在Tomcat的这个目录下建立你想要的文件夹就可以了

也可以直接在工程下建立目录
