我在页面上一点击查询。console以下就有例如以下的红色文字：

2014-8-19 15:09:27 org.apache.jasper.compiler.TldLocationsCache tldScanJar

信息: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation
time.

从控制台看的出来这里卡顿了一两秒，也就是说后台已经把数据查询出来，可是页面没有显示。原因是tomcat对于页面el表达式的校验。

解决方式是：把你的页面中含有$的<!---->的凝视 去掉就好了。或者将凝视换成<%-- --%>
