/**
 * <p>Title: </p>
 *
 * <p>Description:
 * 单独验证并取值置于HashMap中：类型(String int Date String[] int[])，域名，描述, null=(not|empty|allow|current|ip),format=(yyyy-mm-dd), email=(true|false), min(>|>=)20, max(<|<=)20,isNotCN=true|false 如果出错则退出验证,sql=SQLSERVER|MYSQL|ORACLE(用于SQL语句)
 * 联合验证： 表单域名称1 >= | <= | = 表单域名称2
 * 例：String, code, 编码, not, email=true, min<=20 max=30, isNotCN=true, exclude=#|;|", sql=sqlserver 表示类型为string型的变量code，名称为编码，不允许为空......
 * format=yyyy-MM-dd HH:mm:ss
 * 固定格式：第一个必须是类型，第一个必须是域名，第三个是域的描述，第四个必须是能否为null，字符串中一律使用小写
 * null=not|empty　not表示不能为空empty置其为空字符串
 * 字符串类型时min表示最小长度，max表示最大长度
 * int类型时min表示最小值，max表示最大值
 * Date类型时 current表示当前时间 min表示日期的最小值, max表示日期的最大值
 * 说明：对于大小写不敏感，如RegName,将会被转换为regname
 * 域的描述格式：　#资源名称
 *               非#开头，表示直接使用
 * 资源文件中的key使用小写
