AREX Test Service

AREX Java Agent (arextest/arex-agent-java)

Current Behavior

应用接上 arex-agent.jar，进行流量录制。
当请求中触发 getBucket(String name, Codec codec) API，且 Codec 不是 org.redisson.codec.Kryo5Codec，则程序报错。

public final class Redisson implements RedissonClient {
    @Override
    public <V> RBucket<V> getBucket(String name, Codec codec) {
        return new RedissonBucket<>(codec, commandExecutor, name);
    }
}

Expected Behavior

不报错，正常获得 redis 中的数据。

Steps To Reproduce

1. 本地启动一个 redis 服务
   docker pull redis:6.2.17
   docker run --name my_redis -p 6379:6379 -d redis:6.2.17

2. 拉取复现代码
   git clone https://github.com/wangquanchn/arex_redisson_error_case.git
   进入目录
   cd arex_redisson_error_case

3. 正常 case
   3.1 启动应用
   mvn spring-boot:run
   3.2 设置 redis 数据，程序正常返回
   curl --location 'http://127.0.0.1:8080/redisson/setBucket'
   3.3 查询 redis 数据，程序正常返回
   curl --location 'http://127.0.0.1:8080/redisson/getBucket'
   3.4 Ctri + C 停止应用

4. 报错 case
   4.1 接入 arex agent，重新启动应用，注意这里替换 ${path} 和 ${your_storage_host}
   mvn spring-boot:run -Dspring-boot.run.jvmArguments="-javaagent:/${path}/arex-agent.0.4.8.jar -Darex.service.name=arex.agent.test -Darex.storage.service.host=${your_storage_host}"
   4.2 查询 redis 数据，发生报错
   curl --location 'http://127.0.0.1:8080/redisson/getBucket'
