我需要在Firebase中存储像“áčšěž”这样的多字节字符串。当我使用Javascript API时 - 它的工作原理和字符串“áčšěž”在Firebase中。但是当我在Java ref.setValue("áčšěž");中尝试它时它不起作用。没有错误消息，但Firebase将我的客户端设置为已断开连接，但未触发方法onDisconnect。
我的servlet代码是：
@SuppressWarnings("serial")
@WebServlet(urlPatterns = {"/server/*", "/set/*"})
public class FbServlet extends HttpServlet {
private final Firebase ref = new Firebase(FbRef.refD + "xx");
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
ref.child("first").setValue("work"); //this is the first time okey
ref.child("nowork").setValue("áčšěž"); //this do not work and after this command firebase do not work
ref.child("last").setValue("dontwork"); //this do not work
}
}
我在WildFly 8和Tomcat 7.0.41上尝试。我使用的是JDK 1.7，maven和Windows XP。
然后我尝试推送到Openshift（WildFly 8）并且它可以工作，但是写了“?????”。 ：（
所以我的问题是，是否有办法如何做到这一点？ （逃避字符串，或类似的东西）
