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;
   }

}

@Datapublic 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;	}}

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    @EncryptFiled    private String openid;     /**     *      * channel_id:channel_id VARCHAR(128)     *  */     @DecryptFiled     @EncryptFiled    private String channelId;     /**     *      * channel_name:channel_name VARCHAR(128)     */     @DecryptFiled     @EncryptFiled    private 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

数据库中数据
