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")
	@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
