使用Guava获取私有域名时出错 [英] errors when using Guava to get the private domain name

问题描述

我正在使用 guava-18.0 和 java1.6

给出以下代码：

String host = null;
host = new URI(this.domain).getHost();
        Pattern p = Pattern.compile("[a-zA-Z]");
        Matcher m = p.matcher(host);
        if(m.find()){
            InternetDomainName domainName = InternetDomainName.from(host);
            this.domain = domainName.topPrivateDomain().name();
            System.out.println(this.domain);
        }
        else
            this.domain = host;

当运行ant构建时，它会显示以下错误消息：

When running ant to build, it gives such error message:

[javac] symbol  : method name()
[javac] location: class com.google.common.net.InternetDomainName
[javac]                             this.domain = domainName.topPrivateDomain().name();
[javac]                                                                        ^
[javac] Note: Some input files use unchecked or unsafe operations.
[javac] Note: Recompile with -Xlint:unchecked for details.
[javac] 1 error

方法 topPrivateDomain 返回一个 InternetDomainName 对象，它有一个名为 name（）的方法。有什么问题？

the method topPrivateDomain returns a InternetDomainName object and it do has a method called name(). What's the problem?

推荐答案

InternetDomainName 没有 name（）方法。它直到15.0，但在16.0被删除。使用 toString（）。

InternetDomainName does not have a name() method. It did up until 15.0, but it was removed in 16.0. Use toString().
