### 1 : 背景 ###

最近系统需要做用户密码升级，增加强密码校验，密码长度，复杂度等等，所以整理了一份通用的密码复杂度控制代码。  
目的：实现一套拿来即用的密码验证功能，可灵活配置，随意挑选规则。需实现可复用性，可迁移性等。

1、引入密码等级概念。  
即框定规则，等级数为满足规则的数量，这样等级越高，规则越复杂。  
但缺点为不可控，故放弃次方式。  
2、仅引入密码开关，密码规则概念。  
密码开关做总控，密码规则开关做细分管控，方便随意搭配密码规则。

### 2 : 代码设计编写 ###

#### 2.1 : 引入规则配置 ####

1、密码检测总控开关  
2、密码长度控制开关  
3、数字、小写字母、大写字母、特殊符号控制开关  
4、键盘横向连续检测开关，如qwer等  
5、键盘斜向连续检测开关  
6、逻辑位置连续检测开关，如1234、abcd等  
7、相邻字符相同检测开关，如aaaa、1111、\#\#\#\#等  
8、自定义密码检测开关，如固定字符等  
由此引入yml配置如下  
application.yml

server:
      port: 8080
      servlet:
        context-path: /project
    
    password:
      #密码检测总控开关
      passwordCheckSwitch: true
      #密码长度控制开关
      checkPasswordLength: true
      limitPasswordMinLength: 8
      limitPasswordMaxLength: 20
      #数字、小写字母、大写字母、特殊符号控制开关
      checkContainDigit: true
      checkContainUpperLowerCase: false
      checkContainLowerCase: true
      checkContainUpperCase: true
      checkContainSpecialChar: false
      defaultSpecialChar: "!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~"
      #键盘横向连续检测开关，如qwer等
      checkHorizontalKeySequential: false
      limitHorizontalKeyNumber: 3
      #键盘斜向连续检测开关
      checkSlopeKeySequential: false
      limitSlopeKeyNumber: 3
      #逻辑位置连续检测开关，如1234、abcd等
      checkLogicSequential: false
      limitLogicNumber: 3
      #相邻字符相同检测开关，如aaaa、1111、####等
      checkSequentialCharSame: false
      limitSequentialCharNumber: 3
      #自定义密码检测开关，如固定字符等
      checkCustomPasswordArray: true

引入自定义密码文件：password.txt

123456
    123456789
    1234567890
    1234561314
    admin1234
    test1234
    123abc

以上配置引入，在代码中如何注入，可参考文末链接。

### 3 : 验证 ###

需要注意的是，配置文件交给Spring管理的，所以验证时，需要将项目启动。

public static void main(String[] args) {
        
        Boolean check = checkPassword("123");
        System.out.print(check);
    }
