接受与Windows Server 2012上运行的Solr / Jetty实例的远程连接(Accept remote connections to Solr/Jetty instance running on Windows Server 2012)

 我正在Windows Server 2012上运行Solr 4.10.1 Jetty实例。我正在使用下载附带的简单示例Jetty版本，并运行java -jar start.jar （来自solr-4.10.1 \ example）我能够通过http://localhost:8983/solr从Windows Server访问我的Solr实例。  
 现在我想远程访问Solr / Jetty实例，即从另一台计算机访问。 即我希望能够通过HTTTP调用访问我的Windows服务器上运行的Solr实例到http://<server IP>:8080/solr和/或http://<server_domain>:8080/solr来自远程客户端的http://<server_domain>:8080/solr /电脑。  
 我在我的Windows Server上创建了入站防火墙规则，接受本地端口8080上的任何远程地址，并且我已将jetty.xml上的jetty端口更改为8080，这很正常（我可以在http://localhost:8080/solr上访问Solr实例） http://localhost:8080/solr来自我的Windows Server的http://localhost:8080/solr ）。 但是当我尝试将jetty主机更改为服务器的IP时，我无法再访问Solr核心集合 - 即核心选择器中没有集合，因此我无法对'http://<server IP>/solr/#/collection1/'执行任何查询'http://<server IP>/solr/#/collection1/' - 我只看到一个“空白”Solr接口。  
 我改变的jetty.xml部分看起来像这样：  
<Call name="addConnector">
  <Arg>
      <New class="org.eclipse.jetty.server.bio.SocketConnector">
        <Set name="host"><SystemProperty name="jetty.host" default="<WINDOWS_SERVER_IP>"/></Set>
        <Set name="port"><SystemProperty name="jetty.port" default="8080"/></Set>
        <Set name="maxIdleTime">50000</Set>
        <Set name="lowResourceMaxIdleTime">1500</Set>
        <Set name="statsOn">false</Set>
      </New>
  </Arg>
</Call>
 
 首先 - 这是正确的方法吗？ 如果是的话，我做错了什么？ 如果不是，我该如何实现呢？ 我试图寻找方法来做到这一点，但我似乎找不到任何好的资源。 

I'm running a Solr 4.10.1 Jetty instance on Windows Server 2012. I'm using the simple example Jetty version that ships with the download, and by running java -jar start.jar (from solr-4.10.1\example) I was able to access my Solr instance from the Windows Server via http://localhost:8983/solr. 
Now I want to access the Solr/Jetty instance remotely, i.e. from another computer. I.e. I want to be able to access the Solr instance running on my Windows Server via HTTTP calls to http://<server IP>:8080/solr and/or http://<server_domain>:8080/solr from a remote client/computer. 
I've created an inbound Firewall rule on my Windows Server, accepting any remote address on local port 8080, and I've changed the jetty port on the jetty.xml to 8080, which works fine (I can access the Solr instance on http://localhost:8080/solr from my Windows Server). But when I try to change the jetty host to the IP of the server, I can't access the Solr core collection any more - i.e. there are no collections in the core selector, so I cannot perform any queries on 'http://<server IP>/solr/#/collection1/' - I only see a "blank" Solr interface. 
The part of the jetty.xml I changed looks like this: 
<Call name="addConnector">
  <Arg>
      <New class="org.eclipse.jetty.server.bio.SocketConnector">
        <Set name="host"><SystemProperty name="jetty.host" default="<WINDOWS_SERVER_IP>"/></Set>
        <Set name="port"><SystemProperty name="jetty.port" default="8080"/></Set>
        <Set name="maxIdleTime">50000</Set>
        <Set name="lowResourceMaxIdleTime">1500</Set>
        <Set name="statsOn">false</Set>
      </New>
  </Arg>
</Call>
 
First of all - is this the correct approach? If yes, what am I doing wrong? If no, how can I achieve it? I've tried to search for ways to do this, but I can't seem to find any good resources.

 在您的MainActivity中，将其替换为：  
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        BottomNavigationView bottomNav = findViewById(R.id.bottom_navigation);
        bottomNav.setOnNavigationItemSelectedListener(navListener);

        //I added this if statement to keep the selected fragment when rotating the device
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
                    new HomeFragment()).commit();
        }
    }
 
 有了这个：  
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        BottomNavigationView bottomNav = findViewById(R.id.bottom_navigation);
        bottomNav.setOnNavigationItemSelectedListener(navListener);

        //I added this if statement to keep the selected fragment when rotating the device
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
                    new HomeFragment()).commit();
        }

        bottomNav.setSelectedItemId(R.id.nav_favorites);
    }
 
 我们基本上只是将这一行添加到onCreate（）函数的末尾：  
bottomNav.setSelectedItemId(R.id.nav_favorites);

In your MainActivity, replace this: 
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        BottomNavigationView bottomNav = findViewById(R.id.bottom_navigation);
        bottomNav.setOnNavigationItemSelectedListener(navListener);

        //I added this if statement to keep the selected fragment when rotating the device
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
                    new HomeFragment()).commit();
        }
    }
 
with this: 
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        BottomNavigationView bottomNav = findViewById(R.id.bottom_navigation);
        bottomNav.setOnNavigationItemSelectedListener(navListener);

        //I added this if statement to keep the selected fragment when rotating the device
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
                    new HomeFragment()).commit();
        }

        bottomNav.setSelectedItemId(R.id.nav_favorites);
    }
 
We're basically just adding this line to the end of the onCreate() function: 
bottomNav.setSelectedItemId(R.id.nav_favorites);
