【问题描述】:
我正在使用guava-18.0 和java1.6
给定以下代码:
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;
运行ant构建时,报错如下:
[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
topPrivateDomain 方法返回一个InternetDomainName 对象,它确实有一个名为name() 的方法。有什么问题?
