我想从我的java applet中确定本地IP地址.问题是当同一台机器上有多个IP地址时,它们有LAN和互联网连接(掌上电脑,VMWare ......).

这是我的测试:

    public static void main(String[] args) {
      try {
        String hostName = InetAddress.getLocalHost().getHostName();
        System.out.println("HostName = " + hostName);
        System.out.println("HostAddressLocal = " +
          InetAddress.getLocalHost().getHostAddress());
        InetAddress[] inetAddresses = InetAddress.getAllByName(hostName);
        for (InetAddress inetAddress : inetAddresses) {
          System.out.println("hostAddress = " + inetAddress.getHostAddress());
        }
      } catch (Exception e) {
          e.printStackTrace();
      }
    }

结果是:

    HostName = xxxx
    HostAddressLocal = xx.xx.xx.xx
    hostAddress = 10.10.11.51
    hostAddress = 192.168.23.1
    hostAddress = 192.168.106.1

其中xx.xx.xx.xx不是正确的地址.正确的是10.10.11.51.

编辑以回应jarnbjo:

你的水晶球说实话.你了解我的问题.客户端可以通过代理连接,因此我无法使用您的第一点.如果我在我的电脑上执行以下代码:

    Socket s = new Socket("www.w3c.org", 80); 
    InetAddress ip = …

我想在pom.xml中转义一个属性.不是在资源中,我知道可以使用过滤器.例如,我尝试使用launch4j插件,如下所示:

<plugin>
<groupId>org.bluestemsoftware.open.maven.plugin</groupId>
            <artifactId>launch4j-plugin</artifactId>
                <executions>
                    <execution>
                        <id>l4j-cli</id>
                        <phase>install</phase>
                        <goals>
                            <goal>launch4j</goal>
                        </goals>
                        <configuration>
                            <headerType>console</headerType>
                            <outfile>../out.exe</outfile>
                            <dontWrapJar>true</dontWrapJar>
                            <jar>./../out.jar</jar>
                            <icon>../icon.ico</icon>
                            <chdir>.</chdir>
                            <customProcName>true</customProcName>
                            <downloadUrl>http://www.oracle.com/technetwork/java/javase/downloads/index.html</downloadUrl>
                            <classPath>
                                <mainClass>com.stack.Main</mainClass>
                                <addDependencies>true</addDependencies>
                                <jarLocation>./lib</jarLocation>
                            </classPath>
                            <jre>
                                <opts>
                                    <opt>-DconfigBasePath=${ALLUSERSPROFILE}/dir</opt>
       </opts>                          
                            </jre>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

并且$ {ALLUSERSPROFILE}不能由maven解释,而是由launch4j生成的程序.我尝试:

\${ALLUSERSPROFILE}
\\${ALLUSERSPROFILE}
$${ALLUSERSPROFILE}

和

<properties>
   <dollar>$</dollar>
</properties>
${dollar}{ALLUSERSPROFILE}

但没什么用.
