使用将 WEB-INF\view\jsp\default\ui\casLoginView.jsp中
<!--也许是tomcat版本问题导致,替换为下面的代码<c:set var="query" value="<%=request.getQueryString() == null ? "" : request.getQueryString().replaceAll("&locale=(_)?|^locale=(_)?", "")%>" />
<c:set var="query" value="<%=request.getQueryString() == null ? \"\" : request.getQueryString().replaceAll(\"&locale=(_)?|^locale=(_)?\", \"\")%>" />-->
<c:set var="query" value="<%=request.getQueryString() == null ? "" : request.getQueryString().replaceAll("&locale=(_)?|^locale=(_)?", "")%>" />
修改了也没用，后来找到老外的解决方法
在catalina.bat中，在里面（前面）加上设置参数：
export JAVA_OPTS="-Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false"
结果小猫都启不动了
我自己修改为:
set JAVA_OPTS="-Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false"
启动小猫，访问https://localhost:8443/cas
终于看到登录的界面了。
被修改的那个参数具体描述请看：http://tomcat.apache.org/tomcat-5.5-doc/config/systemprops.html
