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
数据库中数据
查询出的数据
