安裝

git clone https://github.com/alibaba/jvm-sandbox-repeater.git
cd jvm-sandbox-repeater/bin
./bootstrap.sh

執行完成后應該會在用戶根目錄cd ~生成一個 sandbox 目錄，並且會啟動一個 SpringBoot （Demo）應用（啟動失敗也無所謂，直接用自己的Java應用更方便）

也可以直接執行curl -s http://sandbox-ecological.oss-cn-hangzhou.aliyuncs.com/install-repeater.sh | sh
僅安裝 sandbox，不部署 Demo 應用

}

說明

配置項	釋義
useTtl	是否開啟ttl線程上下文切換，開啟之后，才能將並發線程中發生的子調用記錄下來，否則無法錄制到並發子線程的子調用信息
degrade	是否執行錄制降級策略，開啟之后，不進行錄制，只處理回放請求
exceptionThreshold	異常發生閾值；默認1000
sampleRate	采樣率；最小力度萬分之一；默認值：10000
pluginsPath	插件地址
httpEntrancePatterns	由於HTTP接口的量太大（前后端未分離的情況可能還有靜態資源）因此必須走白名單匹配模式才錄制
javaEntranceBehaviors	java入口插件動態增強的行為
javaSubInvokeBehaviors	java子調用插件動態增強的行為
pluginIdentities	需要啟動的插件
repeatIdentities	回放器插件

示例

該配置實現了對/perf路徑下接口的錄制；
mock了JPA中的兩個mongo查詢方法；
