数据脱敏sensitive(前端或数据库加密，解密)

可以对数据加密，解密，对数据库加密的数据进行解密显示，对数据库没有加密的数据进行加密处理展示前端等待

1：引入数据如下结构

1-1：SensitiveDecode脱敏解密注解

package com.example.poi.desensitization.annotation;

import java.lang.annotation.*;

/**
 * 脱敏解密注解
 * @Author xu
 * @create 2023/9/4 19
 */
@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target({
    
    ElementType.METHOD})
public @interface SensitiveDecode {
    
    

    /**
     * 指明需要脱敏的实体类class
     * @return
     */
    Class entity() default Object.class;
}

1-2：SensitiveEncode脱敏加密注解

package com.example.poi.desensitization.annotation;

import java.lang.annotation.*;

/**
 * 脱敏加密注解
 * @Author xu
 * @create 2023/9/4 19

@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target({
    
    ElementType.METHOD})

    /**
     * 指明需要脱敏的实体类class
     * @return
     */
    Class entity() default Object.class;
}

1-3：SensitiveField字段注解

package com.example.poi.desensitization.annotation;

import com.example.poi.desensitization.enums.SensitiveEnum;

import java.lang.annotation.*;

/**
 * 字段上定义，标识字段存储的信息是敏感的
 * @Author xu
 * @create 2023/9/4 19
 */
@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.FIELD)
public @interface SensitiveField {
    
    

    /**
