我相关问一下，应用和数据库不在这台电脑上，也就是把数据放在另一台上，通过jdbc.properties配置，能不能正常使用，有没有具体测试过

ERROR org.hibernate.util.JDBCExceptionReporter - An attempt by a client to checkout a Connection has timed out. 
肯定是可以的，你这数据库都联不通
ERROR freemarker.runtime - Expression tag_bean is undefined on line 135, column 77 in WEB-INF/t/cms/www/red/index/首页.html. 
这种就是连上了，你模版乱码了，你上传的时候没选UTF-8编码，或者你的服务器不支持中文吧
