在一次做非常复杂的ajax应用时，如果一个会话已经超时，但是此时再通过ajax请求，那么ajax返回的则是一个登陆页面的html，那这下就惨了，页面上而已就乱了，那么，能否在java端，如拦截器里判断客户的的请求是否是ajax请求呢，经过查询，能. 
   普通请求与ajax请求的报文头不一样，通过如下 

Java代码  
String requestType = request.getHeader("X-Requested-With");  

如果requestType能拿到值，并且值为XMLHttpRequest,表示客户端的请求为异步请求，那自然是ajax请求了，反之如果为null,则是普通的请求

报 ClassNotFoundException: org.hibernate.cache.TimestampsRegion

 hibernate.cache.region.factory_class=org.hibernate.cache.ehcache.EhCacheRegionFactory  

报 ClassNotFoundException: org.hibernate.cache.ehcache.EhCacheRegionFactory

后来找到原因，   net.sf.ehcache.hibernate.EhCacheRegionFactory  不支持hibernate4

hibernate4支持ehcache的话，需要引入

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-ehcache</artifactId>
  <version>4.1.2.Final</version>
</dependency>

]]>不安装apache的情况下，使用ab工具http://www.blogjava.net/leafcold/archive/2012/06/03/379847.htmlleafcoldleafcoldSun, 03 Jun 2012 04:36:00 GMThttp://www.blogjava.net/leafcold/archive/2012/06/03/379847.htmlhttp://www.blogjava.net/leafcold/comments/379847.htmlhttp://www.blogjava.net/leafcold/archive/2012/06/03/379847.html#Feedback0http://www.blogjava.net/leafcold/comments/commentRss/379847.htmlhttp://www.blogjava.net/leafcold/services/trackbacks/379847.htmlab的全称是ApacheBench，是 Apache 附带的一个小工具，专门用于 HTTP Server 的benchmark testing，可以同时模拟多个并发请求。
下面的方法是在不安装apache的情况下，使用ab工具，
ab执行需要以下依赖，以下的安装文件在Centos安装盘下都可以找的到 
rpm -ivh apr-1.3.9-3.el6.i686.rpm
rpm -ivh apr-util-1.3.9-3.el6_0.1.i686.rpm
httpd-tools-2.2.15-9.el6.centos.i686.rpm
解压缩
rpm2cpio httpd-tools-2.2.15-9.el6.centos.i686.rpm | cpio -idmv
将usr/bin 下面的文件复制 /usr/bin
同理将usr/share下的文件复制到/usr/share下对应目录下
不仅仅是只有ab工具，还有htdbm htdigest htpasswd logresolve工具

问题： 
org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'int-http:inbound-channel-adapter'
真正的原因是缺少了所需要的jar包，将相关的JAR文件引入到Classpath即可
要是把错误信息进一步明确化，提示开发人员 NoClassFoundException异常更直观一点
