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 1 楼 flynofry 2010-02-09 <div class="quote_title">servlet spe 写道</div>

<p>?所以getRealPath（）最好不要用，像打成war包时会返回null</p> 2 楼 超级潜水艇 2010-02-09 <div class="quote_title">flynofry 写道</div>

<p>打包成WAR最后运行的时候不也要解压成文件夹的形式吗？有什么错？</p> 3 楼 hongyuan19 2010-02-09 <div class="quote_title">超级潜水艇 写道</div><div class="quote_div"><div class="quote_title">flynofry 写道</div>
