我使用Ant作为服务器的安装脚本,我们需要获取服务器的完全限定名称。我如何使用Ant获取它,或者在Ant中可以获得它?
完全限定的主机名如下:xxx.company.com
答案 0 :(得分:7)
<exec executable="hostname" outputproperty="computer.hostname"/>
将在linux和windows上运行,否则使用Marc O'Connor的groovy解决方案
nslookup也适用于linux和windows,如果你需要fullhostname,你必须在名称后解析条目:在nslookup ServerName
输出中,使用:
<groovy>
properties.'hostname' = "hostname".execute().text
//or
properties.'hostname' = InetAddress.getLocalHost().getHostName()
properties.'hostnamefull' = "nslookup ${"hostname".execute().text}".execute().text.find(/Name:\s(.+)/).split(/:\s+/)[1]
</groovy>
<echo>
$${hostname} => ${hostname}
$${hostnamefull} => ${hostnamefull}
</echo>

有一个名为HostInfo
的Ant任务,您可以使用它来设置包含当前计算机的主机名和域的属性。
或者,如果你在Linux / Unix上运行,你可以调用hostname
命令:
<exec executable="hostname" outputproperty="myhostname">
<arg line="-f"/>
</exec>
然后${myhostname}
中可以使用完全限定的主机名。
编辑:对于完全独立于平台的解决方案,这样的自定义任务(未经测试)应该可以完成这项工作:
public class GetHost extends Task
{
private String property;
public void setProperty(String property)
{
this.property = property;
}
@Override
public void execute() throws BuildException
{
if (property == null || property.length() == 0)
{
throw new BuildException("Property name must be specified.");
}
else
{
try
{
String hostName = InetAddress.getLocalHost().getHostName();
getProject().setProperty(property, hostName);
}
catch (IOException ex)
{
throw new BuildException(ex);
}
}
}
}
可以使用如下:
<GetHost property="myhostname" />

重新回答我为Maven所做的回答:-)
使用嵌入式groovy脚本执行Java主机名查找:
<groovy>
properties["hostname"] = InetAddress.getLocalHost().getHostName()
</groovy>
项目是自我记录的:
$ ant -p
Buildfile: /home/mark/tmp/build.xml

First install 3rd party dependencies
ant bootstrap
Then run the build

Expect the following output
print-hostname:
[echo] Hostname: ?????

另一种方法是编写一个javascript scriptdef ,在属性中设置此信息。
<scriptdef name="get-hostame" language="javascript">
<attribute name="prefix" /> <![CDATA[
importClass(java.net.InetAddress);
address = InetAddress.getLocalHost();
prefix = attributes.get("prefix");
project.setNewProperty(prefix + ".hostname", address.getHostName());
project.setNewProperty(prefix + ".fqdn", address.getCanonicalHostName());
project.setNewProperty(prefix + ".address", address.getHostAddress());
]]>
</scriptdef>
您可以这样称呼它:
<get-hostame prefix="uwi.host" />
结果如下:
[echoproperties] uwi.host.address=10.666.666.666
[echoproperties] uwi.host.fqdn=myhost.stackoverflow.com
[echoproperties] uwi.host.hostname=myhos

使用环境
<property name="hostname" value="${env.COMPUTERNAME}"/>
