wx.request({

    return ResponseEntity.ok().body(out -> {
        out.write("This is chunk 1".getBytes());
        out.flush();
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            Thread.currentThread().interrupt();

}

按理来说flush了2次，onChunkReceived方法应该回调2次，实际console打印函数只执行了一次，就是全部返回了
