我初始化了一个bvar变量，没有经过expose也能在http网页上观察到bvar的变化，所以expose接口有什么用呢

使用的多维度bvar？能否给下使用代码例子？

不是，单维度的bvar
```
namespace other_metric {
bvar::Adder<int> time;
bvar::Window<bvar::Adder<int> > time_minitue("metric", "time", &time, 60);
}
void increase_bvar() {
while(true){
other_metric::time<<1;
std::this_thread::sleep_for(std::chrono::seconds(1));
}
}
int main(int argc, char* argv[]) {
// Parse gflags. We recommend you to use gflags as well.
GFLAGS_NS::ParseCommandLineFlags(&argc, &argv, true);
// Generally you only need one Server.
brpc::Server server;
// Instance of your service.
example::EchoServiceImpl echo_service_impl;
// Add the service into server. Notice the second parameter, because the
// service is put on stack, we don't want server to delete it, otherwise
// use brpc::SERVER_OWNS_SERVICE.
if (server.AddService(&echo_service_impl,
brpc::SERVER_DOESNT_OWN_SERVICE) != 0) {
LOG(ERROR) << "Fail to add service";
return -1;
}
butil::EndPoint point;
if (!FLAGS_listen_addr.empty()) {
if (butil::str2endpoint(FLAGS_listen_addr.c_str(), &point) < 0) {
LOG(ERROR) << "Invalid listen address:" << FLAGS_listen_addr;
return -1;
}
} else {
point = butil::EndPoint(butil::IP_ANY, FLAGS_port);
}
// Start the server.
brpc::ServerOptions options;
options.idle_timeout_sec = FLAGS_idle_timeout_s;
if (server.Start(point, &options) != 0) {
LOG(ERROR) << "Fail to start EchoServer";
return -1;
}
std::thread t(increase_bvar);
// Wait until Ctrl-C is pressed, then Stop() and Join() the server.
server.RunUntilAskedToQuit();
t.join();
return 0;
}
```

我知道了，源码里Window类型的bvar会在初始化时自动expose，但是Adder不行，需要手动expose。
