request help: application success but the plugins can't work

### Issue description

### Environment

* your apisix-java-plugin-runner version
apisix-plugin-runner:0.3.1-SNAPSHOT
apache/apisix:2.15.1-centos

使用的dockerfile为

```
FROM apache/apisix:2.15.1-centos
#指定镜像创建者信息
MAINTAINER jimyguo
#将宿主机的文件拷贝到容器的具体目录中。这里使用ADD，拷贝后自动解压，如果不需要解压，可以使用COPY
ADD jdk-11.0.16.1_linux-x64_bin.tar.gz /jdk
ADD apache-apisix-java-plugin-runner-0.3.1-SNAPSHOT-bin.tar.gz /opt
ADD apisix-java-plugin-runner-0.3.1-SNAPSHOT-src.tgz /usr/local
#配置jdk环境
ENV JAVA_HOME /jdk/jdk-11.0.16.1
ENV PATH ${JAVA_HOME}/bin:$PATH
```

### Minimal test code / Steps to reproduce the issue
1.在正常打包出来的jar包按照https://github.com/apache/apisix-java-plugin-runner/blob/main/docs/en/latest/how-it-works.md
启动之后以下代码中检出System.getProperty("user.dir")为/usr/local/apisix导致HotReloadProcess.hotReloadFilter()报错
```
String userDir = System.getProperty("user.dir");
System.err.println(userDir);
//使用了这个代码之后加入apisix-java-plugin-runner-0.3.1-SNAPSHOT-src.tgz到/usr/local就无报错
// userDir=userDir.replace("apisix","apisix-java-plugin-runner");
logger.warn("The filter userDir {} ", userDir);
userDir = userDir.substring(0, userDir.lastIndexOf("apisix-java-plugin-runner") + 25);
String workDir = userDir + loadPath;
```

2、修改启动成功后，使用的插件对应的配置为
```
"ext-plugin-pre-req": {
"conf": [
{
"name": "TokenCheckFilter2",
"value": "{\"validate_header\":\"token\",\"rejected_code\":\"403\"}"
}
]
},
```
启动时以下程序的代码没有打印出对应plugin 的日志，如 logger.debug("get plugins List:{}",pluginFilterList),是否就是没有检测到插件并加以使用
```
public void start(String path) throws Exception {
EventLoopGroup group = null;
ServerBootstrap bootstrap = new ServerBootstrap();
logger.debug("choose channel");
System.err.println("choose channel");
if (KQueue.isAvailable()) {
group = new KQueueEventLoopGroup();
logger.debug("Using epoll for Netty transport.");
bootstrap.group(group).channel(KQueueServerDomainSocketChannel.class);
} else if (Epoll.isAvailable()) {
group = new EpollEventLoopGroup();
logger.debug("Using kqueue for Netty transport.");
bootstrap.group(group).channel(EpollServerDomainSocketChannel.class);
} else {
String errMsg = "java runner is only support epoll or kqueue";
logger.debug(errMsg);
throw new RuntimeException(errMsg);
}
logger.debug("choose channel success");
System.err.println("choose channel success");
try {
initServerBootstrap(bootstrap);
ChannelFuture future = bootstrap.bind(new DomainSocketAddress(path)).sync();
Runtime.getRuntime().exec("chmod 777 " + socketFile);
logger.warn("java runner is listening on the socket file: {}", socketFile);

future.channel().closeFuture().sync();
} finally {
group.shutdownGracefully().sync();
}
}
private void initServerBootstrap(ServerBootstrap bootstrap) {
logger.debug("start init bootstrap");
System.err.println("start init bootstrap");
bootstrap.childHandler(new ChannelInitializer() {
@Override
protected void initChannel(DomainSocketChannel channel) {
channel.pipeline().addFirst("logger", new LoggingHandler())
.addAfter("logger", "payloadEncoder", new PayloadEncoder())
.addAfter("payloadEncoder", "delayedDecoder", new BinaryProtocolDecoder())
.addLast("payloadDecoder", new PayloadDecoder())
.addAfter("payloadDecoder", "prepareConfHandler", createConfigReqHandler(cache, beanProvider))
.addAfter("prepareConfHandler", "hTTPReqCallHandler", createA6HttpHandler(cache))
.addLast("exceptionCaughtHandler", new ExceptionCaughtHandler());

}
});
System.err.println("start bootstrap success");
}
public PrepareConfHandler createConfigReqHandler(Cache cache, ObjectProvider beanProvider) {
List pluginFilterList = beanProvider.orderedStream().collect(Collectors.toList());
Map filterMap = new HashMap<>();
logger.debug("get plugins List:{}",pluginFilterList);
System.err.println("get plugins List:"+pluginFilterList);
for (PluginFilter filter : pluginFilterList) {
System.err.println(filter.name());
filterMap.put(filter.name(), filter);
}
return new PrepareConfHandler(cache, filterMap);
}
```
日志如下:

```

调用了接口之后时应该会使用到TokenCheckFilter2
```
@Override
public String name() {
return "TokenCheckFilter2";
}
@Override
public void filter(HttpRequest request, HttpResponse response, PluginFilterChain chain) {
log.info("TokenCheckFilter start");
// parse `conf` to json
String configStr = request.getConfig(this);
Gson gson = new Gson();
Map conf = new HashMap<>();
conf = gson.fromJson(configStr, conf.getClass());

// get configuration parameters
String token = request.getHeader((String) conf.get("validate_header"));// token verification results

Map headers = request.getHeaders();

Map body = new HashMap<>();
body = gson.fromJson(request.getBody(),body.getClass());// token verification results

Map params = request.getArgs();
String rejectedCode ="0";
if(checkAppIdToken(body)){
log.info("token success");
response.setBody(JsonResult.success().toString());
}else {
if(checkAppIdToken(params)) {
log.info("token success");
response.setBody(JsonResult.success().toString());
}else {
log.info("token failed");
rejectedCode = (String) conf.get("rejected_code");
response.setStatusCode(Integer.parseInt(rejectedCode));
response.setHeader("x-token","no token");
response.setBody(JsonResult.fail(GlobalResultStatus.AUTH_MISSING).toString());
}
}
chain.filter(request, response);
}
public boolean checkAppIdToken(Map map) {
return map.containsKey("appId")&& map.containsKey("accessToken");
}
@Override
public void postFilter(PostRequest request, PostResponse response, PluginFilterChain chain) {

}
@Override
public List requiredVars() {
List vars = new ArrayList<>();
vars.add("appId");
vars.add("accessToken");
return vars;
}

@Override
public Boolean requiredBody() {
return true;
}
```
在容器调用链接后返回结果为

对应的日志为
```

```
能够直接访问且没有出现对应插件中的日志打印，故判断插件确实没有生效

### What's the actual result? (including assertion message & call stack if applicable)
请求没有通过插件的检测返回配置的数据，能够访问成功
### What's the expected result?

当请求没有待遇偶需要的appId和accessToken会返回接口配置的rejected_code:403.
