java 数据脱敏

所谓数据脱敏是指对某些敏感信息通过脱敏规则进行数据的变形，实现敏感隐私数据的可靠保护。在涉及客户安全数据或者一些商业性敏感数据的情况下，在不违反系统规则条件下，对真实数据进行改造并提供测试使用，如身份证号、手机号、卡号、客户号等个人信息都需要进行数据脱敏。

　　此随笔是根据其他文章修改后符合自己项目使用的数据脱敏！！

　

以下是根据别的文章修改或者直接拿过来用的代码

脱敏enum

/**
 * @Title: SensitiveTypeEnum
 * @Description:
 */
public enum SensitiveTypeEnum {
    /**
     * 中文名
     */
    CHINESE_NAME,
    /**
     * 身份证号
     */
    ID_CARD,
    /**
     * 座机号

    FIXED_PHONE,
    /**
     * 手机号
     */
    MOBILE_PHONE,
    /**

    ADDRESS,
    /**

    /**

    BANK_CARD,

Controller

    @Autowired
    private BlackListService blackListService;

     */
    @SuppressWarnings("rawtypes")
    @RequestMapping(value = "/getBlackListPage")
    @ResponseBody
    public JsonResponseExt getBlackListPage(BlackList info, @RequestParam("page")String page, @RequestParam("limit") String limit) {

        Page<BlackList> pageData =blackListService.getBlackListPage(info,Integer.parseInt(page) - 1,Integer.parseInt(limit));

　　　　 JsonResponseExt je = JsonResponseExt.successPage(DesensitizedUtils.desensitizedPage(pageData,Integer.parseInt(page) - 1,Integer.parseInt(limit),BlackListVO.class));

　　　　 return je; 
　　} 
}

JsonResponseExt je = JsonResponseExt.successPage()这个方法是自己封装给前端的返回对象（这里不提供）

根据工具类的 DesensitizedUtils.desensitizedPage()方法 传入自定义对象、page、list和VO对象的Class对象就可以进行脱敏了
