web系统数据库敏感数据处理

一、前言

web系统数据库中保存的公民信息不允许明文存储，比如手机号，身份证号，收货地址等。

二、处理方式

数据库中密文存储，web通过注解的方式对数据加解密处理，下面是处理方法

1、编写接口

public interface  EncryptDecryptInterface {
      public <T> T encryptSelf();
        public <T> T decryptSelf();

        public <T> List<T>  encryptSelfList(List<T> c);
        public <T> List<T>  decryptSelfList(List<T> c);
 
}

public interface  EncryptDecryptInterface {public <T> T encryptSelf();public <T> T decryptSelf();public <T> List<T>  encryptSelfList(List<T> c);public <T> List<T>  decryptSelfList(List<T> c);}

2、接口实现

@Data
public class BaseEntity implements Serializable, Cloneable, EncryptDecryptInterface {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    /**
     * 数据归属码
     */
    private String belongCode;

    /**
     * 数据归属名称
     */
    private String belongName;

    /**
     * 数据类型
     */
    private String dataType;

    @SuppressWarnings("unchecked")
    @Override
    public <T> T encryptSelf() {
        toCommaint(this, EncryptFiled.class, "Encrypt");
        return (T) this;
    }

    @SuppressWarnings("unchecked")
    @Override
    public <T> T decryptSelf() {
        toCommaint(this, DecryptFiled.class, "Decrypt");
        return (T) this;
    }

    @Override
    public <T> List<T> encryptSelfList(List<T> l) {
        for (T t : l) {
            toCommaint(t, EncryptFiled.class, "Encrypt");
        }
        return l;
    }

    @Override
    public <T> List<T> decryptSelfList(List<T> l) {
        for (T t : l) {
            toCommaint(t, DecryptFiled.class, "Decrypt");
        }
        return l;
    }

    /**
     * 描述：转换方法
     * 
     * @auter dongjing.chen
     * @create 2022/4/20 16:31
     */
    @SuppressWarnings("unchecked")
    public <T> T toCommaint(T t, @SuppressWarnings("rawtypes") Class c, String type) {

        Field[] declaredFields = t.getClass().getDeclaredFields();
        try {
            if (declaredFields != null && declaredFields.length > 0) {
                for (Field field : declaredFields) {
                    if (field.isAnnotationPresent(c) && field.getType().toString().endsWith("String")) {
                        field.setAccessible(true);
                        String fieldValue = (String) field.get(t);
                        if (StringUtils.isNotEmpty(fieldValue)) {

                            if (type.equals("Decrypt")) {
                                fieldValue = PGSQLUtils.decrypt(fieldValue);
                            } else if (type.equals("Encrypt")) {
                                fieldValue = PGSQLUtils.encrypt(fieldValue);
                            }

                            field.set(t, fieldValue);
                        }
                    }
                }
            }
        } catch (IllegalAccessException e) {
            throw new RuntimeException(e);
        }
        return t;
    }

}

@Data
public class BaseEntity implements Serializable, Cloneable, EncryptDecryptInterface {/*** */private static final long serialVersionUID = 1L;/*** 数据归属码*/private String belongCode;/*** 数据归属名称*/private String belongName;/*** 数据类型*/private String dataType;@SuppressWarnings("unchecked")@Overridepublic <T> T encryptSelf() {toCommaint(this, EncryptFiled.class, "Encrypt");return (T) this;}@SuppressWarnings("unchecked")@Overridepublic <T> T decryptSelf() {toCommaint(this, DecryptFiled.class, "Decrypt");return (T) this;}@Overridepublic <T> List<T> encryptSelfList(List<T> l) {for (T t : l) {toCommaint(t, EncryptFiled.class, "Encrypt");}return l;}@Overridepublic <T> List<T> decryptSelfList(List<T> l) {for (T t : l) {toCommaint(t, DecryptFiled.class, "Decrypt");}return l;}/*** 描述：转换方法* * @auter dongjing.chen* @create 2022/4/20 16:31*/@SuppressWarnings("unchecked")public <T> T toCommaint(T t, @SuppressWarnings("rawtypes") Class c, String type) {Field[] declaredFields = t.getClass().getDeclaredFields();try {if (declaredFields != null && declaredFields.length > 0) {for (Field field : declaredFields) {if (field.isAnnotationPresent(c) && field.getType().toString().endsWith("String")) {field.setAccessible(true);String fieldValue = (String) field.get(t);if (StringUtils.isNotEmpty(fieldValue)) {if (type.equals("Decrypt")) {fieldValue = PGSQLUtils.decrypt(fieldValue);} else if (type.equals("Encrypt")) {fieldValue = PGSQLUtils.encrypt(fieldValue);}field.set(t, fieldValue);}}}}} catch (IllegalAccessException e) {throw new RuntimeException(e);}return t;}}

3、编写注解类

@Target(ElementType.FIELD)
@Retention(RetentionPolicy.RUNTIME)
public @interface EncryptFiled {
     String value() default "";
}

@Target(ElementType.FIELD)
@Retention(RetentionPolicy.RUNTIME)
public @interface EncryptFiled {String value() default "";
}

4、需要加解密的实体类注解方式示例

@Data
@EqualsAndHashCode()
@TableName(value="jiami_test",schema = "public")
public class JiamiTest extends BaseEntity implements Serializable{/*** 序列*/private static final long serialVersionUID = 1L;/*** * openid:openid VARCHAR(128)*/@DecryptFiled@EncryptFiledprivate String openid;/*** * channel_id:channel_id VARCHAR(128)*  */@DecryptFiled@EncryptFiledprivate String channelId;/*** * channel_name:channel_name VARCHAR(128)*/@DecryptFiled@EncryptFiledprivate String channelName;/*** * :id INT8(19)*/@TableId(value = "id" ,type = IdType.ASSIGN_UUID)@ApiModelProperty(value = "ID")private String id;}

4、调用

/*** 查询所有加解密测试列表* @param  * @return*/@ApiOperation(value = "查询所有加解密测试列表", notes = "查询所有加解密测试列表")@PostMapping("searchAll")public ResponseData<List<JiamiTest>> searchAll() {List<JiamiTest> jiamiTestList = jiamiTestService.list();if(!CtgUtils.isCollectionNull(jiamiTestList)) {JiamiTest jiamiTest = new JiamiTest();return  ResponseData.success(jiamiTest.decryptSelfList(jiamiTestList));}else {log.info(JiamiTestConstant.NOT_EXIST);return  ResponseData.success(jiamiTestList);}}/*** 保存加解密测试* @param jiamiTest* @return*/@ApiOperation(value = "保存加解密测试", notes = "保存加解密测试")@PostMapping("save")public ResponseData<String> save(@RequestBody JiamiTest jiamiTest) {boolean res = jiamiTestService.save(jiamiTest.encryptSelf());if(res) {return ResponseData.success(JiamiTestConstant.SAVE_SUCCESS);}else {log.error(JiamiTestConstant.SAVE_FAILED);return ResponseData.error(JiamiTestConstant.SAVE_FAILED);}}

5、效果
