Excel单元格校验

使用Excel批量导入数据，为了避免一些脏数据，在读取Excel文件之后需要对Excel单元格进行校验；具体实现方式如下：

1、配置文件校验格式

{"1031": {"name": "1031","code": "person","column": [{ "name": "所属机构", "type": "GBString", "code": "ndkey" , "rules": [ { "message": "所属机构不允许为空", "name": "required" } ] },{ "name": "用户姓名", "type": "GBString", "code": "usrNam", "rules": [ { "message": "用户姓名不允许为空", "name": "required" } ] },{ "name": "用户角色", "type": "GBString", "code": "usrAut", "rules": [ { "message": "用户角色不允许为空", "name": "required" },{ "message": "用户权限只能为21|22|23", "name": "Auth" } ] },{ "name": "手机号码", "type": "Phone", "code": "usrMph", "rules": [ { "message": "手机号码不允许为空", "name": "required" },{ "message": "非法手机号", "name": "Phone" } ] },{ "name": "邮箱", "type": "Email", "code": "usrEml", "rules": [{ "message": "非法邮箱", "name": "Email" }]},{ "name": "备注", "type": "GBString", "code": "usrMmo" }]}
}

2、读取校验规则

读取配置的json校验文件

}

4、单元格校验规则

import java.util.regex.Pattern;/*** @author 陌上青花* @version 1.0 at 2020年11月17日*/
public class ValidatorUtil {public static final String IS_STRING = "^[a-zA-Z0-9@.\\-]+\\d*$";public static final String IS_GB_STRING = "^(\\\\w*|\\\\W*|[\\\\u0391-\\\\uFFE5]*)*&";public static final String IS_GB_STRING_TB = "^[^'&<>\\\\\"/*]*$";public static final String IS_JF_STRING = "^[\\u0391-\\uFFE5a-zA-Z0-9\\-]+$";public static final String IS_N_STRING = "^[0-9]+\\d*$";public static final String IS_CURRENCY = "^([0-9]{1}\\d*)(\\.(\\d){1,2})?$";public static final String IS_AREA = "^([0-9]{1}\\d*)(\\.(\\d){1,2})?$";public static final String IS_PHONE = "^(((13[0-9]{1})|(14[0-9]{1})|(15[0-9]{1})|(16[0-9]{1})|(17[0-9]{1})|(18[0-9]{1})|(19[0-9]{1}))+\\d{8})$";public static final String IS_MAIL = "^([a-zA-Z0-9]+[-_.]*)*[a-zA-Z0-9]*@([a-zA-Z0-9]+[-_.]*)*[a-zA-Z0-9]+\\.[a-zA-Z]{2,3}$";/*** 校验是否是isString* @param string 待校验参数* @return 校验通过返回true，否则返回false*/public static boolean isString(String string){return Pattern.matches(IS_STRING, string);}/*** 校验是否是isGBString* @param string 待校验参数* @return 校验通过返回true，否则返回false*/public static boolean isGbString(String string){return Pattern.matches(IS_GB_STRING, string) && Pattern.matches(IS_GB_STRING_TB, string);}/*** 校验是否是isJFString* @param string 待校验参数* @return 校验通过返回true，否则返回false*/public static boolean isJfString(String string){return Pattern.matches(IS_JF_STRING, string);}/*** 校验是否是isNString* @param string 待校验参数* @return 校验通过返回true，否则返回false*/public static boolean isnString(String string){return Pattern.matches(IS_N_STRING, string);}/*** 校验是否是isCurrency* @param string 待校验参数* @return 校验通过返回true，否则返回false*/public static boolean isCurrency(String string){boolean maxbid = true;float f = (float) 9999999999999.99;if (Float.parseFloat(string)>f){maxbid = false;}return Pattern.matches(IS_CURRENCY, string)&& maxbid;}/*** 校验是否是isArea* @param string 待校验参数* @return 校验通过返回true，否则返回false*/public static boolean isArea(String string){boolean maxbid = true;float f = (float) 99999999.99;if(Float.parseFloat(string) > f){maxbid = false;}return Pattern.matches(IS_AREA, string) && maxbid;}/*** 校验是否是isPhone* @param string 待校验参数* @return 校验通过返回true，否则返回false*/public static boolean isPhone(String string){return Pattern.matches(IS_PHONE, string);}/*** 校验是否是isMail* @param string 待校验参数* @return 校验通过返回true，否则返回false*/public static boolean isMail(String string){return Pattern.matches(IS_MAIL, string);}}

5、配置规则常量

public class ParseConstans {public static final String RULE_NAME_NULLABLE = "required";public static final String RULE_NAME_IS_STRING = "String";public static final String RULE_NAME_IS_GB_STRING = "GBString";public static final String RULE_NAME_IS_JF_STRING = "JFString";public static final String RULE_NAME_IS_N_STRING = "NString";public static final String RULE_NAME_IS_CURRENCY = "Currency";public static final String RULE_NAME_IS_AREA = "Area";public static final String RULE_NAME_IS_PHONE = "Phone";public static final String RULE_NAME_IS_MAIL = "Mail";}

6、把ParseJsonUtil和ParseExcelUtil交给容器管理

@Configuration
public class SystemBeanCofig {@Value("${excel_check}")private String path;@Beanpublic ParseJsonUtil getParseJsonUtil() throws FileNotFoundException {File file = ResourceUtils.getFile(path);return new ParseJsonUtil(file);}@Beanpublic ParseExcelUtil getParseExcelUtil(ParseJsonUtil parseJsonUtil){return new ParseExcelUtil(parseJsonUtil);}
}
