Attribute Macro idempotency 

#[idempotency]

实现幂等性属性的过程宏

属性参数说明

• name: 可选字符串字面量，指定 IdempotencyStore 的单例名称, 可以指定名称使用自己实现的 Store, 默认为memoryIdempotencyStore
• key: 可选字符串字面量，用于获取请求头的键值，默认值为 Idempotency-key
• cache_key_prefix: 可选字符串字面量，应用再缓存键的前缀
• ttl: 可选整数字面量，缓存存活时间(Time To Live), 默认为秒

注意

当前宏 只支持 Mehod 为 POST 你应该使用 PostMapping 或者 RequestMapping(method = "POST")

示例

#[Idempotency(name = "myIdempotencyStore", key = "Idempotency-key", cache_key_prefix = "test", ttl = 6)]
#[PostMapping(path = "/createOrder")]
async fn create_order(order: String) -> impl IntoResponse {

    "Ok"
}

Description of Attribute Parameters

• name: optional string literal, specifying the singleton name of IdempotencyStore, can specify the name to use their own implemented Store, default is memoryIdempotencyStore '
• key: optional string literal, used to obtain the key value of the request header, default value is ` Idempotency key ``
• cache_key_prefix: optional string literal, apply the prefix of the cached key again
• ttl: optional integer face count, cache live time (Time To Live), default is seconds

Attention

The current macro only supports Mehod as’ POST ’ You should use PostMapping or RequestMapping (method="POST")

Example

#[idempotency(name = "myIdempotencyStore", key = "Idempotency-key", cache_key_prefix = "test", ttl = 6)]
#[PostMapping(path = "/createOrder")]
async fn create_order(order: String) -> impl IntoResponse {

    "Ok"
}
