Java正则表达式汇总_java正则表达式,不能输入引号(单引号和双引号)以及特殊字符<、>、#和&

1.不可包含特殊字符的正则表达式

/^((?!\\|\/|:|\*|\?|<|>|\||'|%|\@|\#|\$|\%|\^|\&|\(|\)|\[|\]|\{|\}|\.|\!|\￥|\+|\=|"|”|“).){1,50}$/

注: /^表示开头，$/表示结尾，中间的\表示转义，|表示或（起连接作用)，(1,50)表示长度范围为1~50

2.字符串不可包含空格（开头结尾不得为空格）

/^\S*$/      //不可包含任何空格
/^\S([\s\S]*\S)?$/  //头尾不可包含空格

3.IP地址校验

/^([1-9]|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])$/
 
 
// 可输入多个，以逗号分隔，校验重复
  public ipValidate(): ValidatorFn {
    return (control: AbstractControl): { [key: string]: any } => {
      let val = control.value;
      var valchange = /^(?:(?:^|,)(?:[0-9]|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])(?:\.(?:[0-9]|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])){3}){0,10}$/;
      if(val.length == 0){
        return {}
      }
      if (!valchange.test(val)) {
        return {
          pattern: true      
        };
      }
      var vals = val.split(',');
      var set=new Set();
      for(var i=0;i<vals.length;i++)
      {
        set.add(vals[i]);
      }
      if(set.size<vals.length)

        return {
          repeat: true
        };
      }
      return {};
    };
  }

4.MAC地址校验

/^([A-Fa-f0-9]{2}:){5}[A-Fa-f0-9]{2}$/)
 
 
//可输入多个，以逗号分隔
//MAC地址校验
  public macValidate(): ValidatorFn {
    return (control: AbstractControl): { [key: string]: any } => {
      let val = control.value;
      var valchange = /^([0-9A-F]{2}-[0-9A-F]{2}-[0-9A-F]{2}-[0-9A-F]{2}-[0-9A-F]{2}-[0-9A-F]{2})(,[0-9A-F]{2}-[0-9A-F]{2}-[0-9A-F]{2}-[0-9A-F]{2}-[0-9A-F]{2}-[0-9A-F]{2})*$/;
      var valchange1 = /^([0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2})(,[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2})*$/;
      var vals = val.split(',');
      if(val.length == 0){
        return {}
      }
      if (val.length > 200) {
        return {
          pattern: true
        };
      }
      else
        for (var i = 0; i < vals.length; i++) {
          if (!valchange.test(vals[i]) && !valchange1.test(vals[i])) {
            return {
              pattern: true
            };
          }
        }
      return {}
    };
  }

5.子网掩码校验

/^((254|252|248|240|224|192|128)\.0\.0\.0|255\.(254|252|248|240|224|192|128|0)\.0\.0|255\.255\.(254|252|248|240|224|192|128|0)\.0|255\.255\.255\.(254|252|248|240|224|192|128|0))$/

7.可输入单条IP或CIDR

/^([0-9]|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])(\.([0-9]|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])){3}(\/([1-9]|[1-2]\d|[3][0-2])){0,1}$/

8.可输入多条IP或CIDR，以分号分隔

/^(?:(?:^|;)(?:[0-9]|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])(\.([0-9]|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])){3}(\/([1-9]|[1-2]\d|[3][0-2])){0,1})+$/

10、强密码校验

/((^(?=.*[a-z])(?=.*[A-Z])(?=.*\W)[\da-zA-Z\W]{8,18}$)|(^(?=.*\d)(?=.*[A-Z])(?=.*\W)[\da-zA-Z\W]{8,18}$)|(^(?=.*\d)(?=.*[a-z])(?=.*\W)[\da-zA-Z\W]{8,18}$)|(^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])[\da-zA-Z\W]{8,18}$))/       //必须包含大写字母，小写字母，数字和特殊符号中的任意3种，8-18字符

11、时间段校验

//1.时间段校验 例11:12~13:11，不可跨天
    /^(0[0-9]|1[0-9]|2[0-3]):[0-5][0-9]~(0[0-9]|1[0-9]|2[0-3]):[0-5][0-9]$/).test(value)
 
 
//2.多个时间段，以逗号分隔，不可跨天
/^((0[0-9]|1[0-9]|2[0-3]):[0-5][0-9]~(0[0-9]|1[0-9]|2[0-3]):[0-5][0-9],){0,4}(0[0-9]|1[0-9]|2[0-3]):[0-5][0-9]~(0[0-9]|1[0-9]|2[0-3]):[0-5][0-9]$/).test(value)
