我可以使用哪些技术来修改一组JSP来衡量JSP的整体性能,然后进一步缩小并确定JSP中花费最多时间的特定区域？

我目前的方法是简单地使用scriptlet和System.currentTimeMillis():

JSP的顶部

<%
StringBuilder result = new StringBuilder();
long startTime = System.currentTimeMillis();
%>

... JSP代码在这里

<%
long duration = System.currentTimeMillis() - startTime;
if (duration > 100L) { //over  100 ms
    result.append("JSP page took "+duration+"ms");
}
%>
<!-- <%=result%> -->

但问题是:

• 使用此性能代码的污染JSP,
• 在几个JSP中复制粘贴的代码,
• 当JSP包含在<%@ include ...%>中时,效果不佳,因为结果变量已经在多个JSP中定义.

我需要为我的Ext JS 4.1.3应用程序使用自定义名为'app'的文件夹.Sencha文档很清楚,这个文件夹名称是一个名为'appFolder'的可配置值.

环境:Ext JS 4.1.3 Sencha Cmd 3.1.2.342 Ruby 1.9

我采取的步骤:

sencha generate workspace C:\temp\workspace 
sencha -sdk C:\tools\extjs4.1.3 generate app common C:\temp\workspace\common 
cd C:\temp\workspace\common 
sencha app build 

SUCCESSFUL 

编辑app.js并设置appFolder:'custom':

Ext.application({ 
    appFolder: 'custom' ...

还将'C:\ temp\workspace\common\app'文件夹重命名为'C:\ temp\workspace\common\custom'

sencha app build.
