16 | * 缓存仅仅是为了业务更快地查询而存在的，如果因为缓存操作失败导致正常的业务流程失败，有点得不偿失了。 17 | * 因此需要开发者自定义 CacheErrorHandler 处理缓存读写的异常。 18 | *

19 | * 20 | *

21 | * 如果缓存写发生了异常，就可能导致数据库的数据和缓存的数据不一致的问题。 22 | * 为了解决该问题，需要继续扩展 CacheErrorHandler 的 handleCachePutError 和 handleCacheEvictError 方法。 23 | * 思路就是将缓存写操作失败的 key 保存下来，通过重试任务删除这些 key 对应的缓存解决数据库数据与缓存数据不一致的问题。 24 | *

/encrypt-examples/frontend-backend-encrypt-with-rsa/README.md: -------------------------------------------------------------------------------- 1 | # 前后端分离数据加密传输 2 | 3 | ## RSA 非对称加密算法 4 | 1977年，三位数学家Rivest、Shamir 和 Adleman 设计了一种算法，可以实现非对称加密。这种算法用他们三个人的名字命名，叫做RSA算法。 5 | 6 | 7 | 这种算法非常可靠，密钥越长，它就越难破解。根据已经披露的文献，目前被破解的最长RSA密钥是768个二进制位。也就是说，长度超过768位的密钥，还无法破解（至少没人公开宣布）。可以认为，1024位的RSA密钥基本安全，2048位的密钥极其安全。 8 | 9 | > 本例子使用的密钥长度为：1024 10 | > 请看 RsaUtils 类 KEY_SIZE 变量 11 | 12 | 13 | ## 原理 14 | 15 | > 后端传输到前端 16 | 17 | 后端使用`AES`加密数据，并使用`RSA私钥`加密`AES密钥`； 18 | 19 | 前端使用`RSA公钥`解密`AES密钥`，再使用解密后的`AES密钥`解密数据。 20 | 21 | > 前端传输到后端 22 | 23 | 前端使用`AES`加密数据，并使用`RSA公钥`加密`AES密钥`； 24 | 25 | 后端使用`RSA私钥`解密前端传过来的`AES密钥`，再使用`RSA`解密后的`AES 密钥`解密数据。 26 | 27 | 28 | ## 为什么使用 RSA 加密 AES 的密钥 29 | 用对称加密算法（比如：`AES`）来加密消息，然后利用`RSA 30 | `称加密算法加密密钥传递。因为在同等安全等级下，`RSA`加密算法作为一种非对称密码学系统，通常比对称加密体制要慢。对称加密算法的密钥和要传递的消息相比通常要短得多，所以相比之下使用`RSA`加密密钥然后用对称加密来加密任意长度的消息，这样要更快很多。 31 | 32 | 33 | ## AES demo 34 |

active: local 11 | ``` 12 | 13 | - 在 [Nacos](https://nacos.io/zh-cn/) 控制台 local 命名空间下新建配置 14 | ```properties 15 | # DATA ID：nacos-spring-boot-example.properties 16 | example.id=123 17 | example.name=nacos-spring-boot-example.properties 18 | 19 | # DATA ID：nacos-spring-boot-example-nacos.properties 20 | example.profile=nacos 21 | ``` 22 | 23 | - 请求

ID：nacos-spring-boot-example.properties 37 | example.id=123456 38 | example.name=nacos-spring-boot-example.properties.new 39 | ``` 40 | - 请求

`sentinel-spring-cloud-example` 项 9 | 10 | 11 | - 添加流控规则 12 | 13 | - 在`簇点链路`菜单选择对 `/demo` 添加流控规则，阈值类型=QPS，单机阈值=0 14 | 15 | - 再次请求 [http://localhost:8080/sentinel/demo](http://localhost:8080/sentinel/demo) 可以看到返回`Blocked by Sentinel (flow 16 | limiting)`，表明配置的流控规则已经生效了。
