request help: how to relate filter function and postFilter function?

### Issue description
如果将filter方法和postFilter方法关联起来，我现在有一个路由配置了ext-plugin-pre-req插件和ext-plugin-post-resp插件，我需要在ext-plugin-pre-req记录接口请求的相关信息(请求路径、请求参数等)，需要在ext-plugin-post-resp插件中记录接口的响应信息(响应结果)，我测试了一下在没有并发的情况下，就简单的单次调用可以正常记录信息，但是在高并发多个接口同时调用时，ext-plugin-pre-req插件的filter方法和ext-plugin-post-resp插件的postFilter方法不是一 一 对应的，导致我不能正确的记录接口请求中的信息，希望老师帮我看下。please help me！

### Environment

* your apisix-java-plugin-runner version
` @Override
public void filter(HttpRequest request, HttpResponse response, PluginFilterChain chain) {
String uuid = UuidUtil.create2();
Thread thread = Thread.currentThread();
thread.setName(uuid);
filterStrs.add(uuid);

String path = request.getPath();
requestPathMaps.put(uuid, path);
// jsonObject.put(uuid, path);
logger.info("【前置请求路径】：" + uuid + "----" + path);

chain.filter(request, response);
}

@Override
public void postFilter(PostRequest request, PostResponse response, PluginFilterChain chain) {
Thread thread = Thread.currentThread();
String uuid = thread.getName();

String findStr = this.filterStrs.stream().filter(p -> p.equals(uuid)).findAny().orElse(null);
boolean flage = findStr != null;

String responseBody = formatBody(request.getBody());
String path = requestPathMaps.get(uuid);

logger.info("【后置结果findStr】：" + flage);
logger.info("【后置接口路径】：" + uuid + "---" + path);
logger.info("【后置接口相应】：" + responseBody);`
