java解析URL中domain、端口和协议的两种方法
Java代码 收藏代码
@Test
public void parseDomain() throws IOException {
for (int i = 0; i < 10000000; i++) {
String urlAddress = “http://www.roseindia.net/jsf/JSFLoginApplication.shtml”;
URL url = new URL(urlAddress);
assertEquals(“www.roseindia.net”, url.getHost());
assertEquals(“/jsf/JSFLoginApplication.shtml”, url.getPath());
assertEquals(-1, url.getPort()); // -1 if not set
assertEquals(“http”, url.getProtocol());
}
}
@Test
public void parseDomainByStringUtils() {
for (int i = 0; i < 10000000; i++) {
String urlAddress = “http://www.roseindia.net/jsf/JSFLoginApplication.shtml”;
assertEquals(“www.roseindia.net”, StringUtils.split(urlAddress, “:/”)[1]);
assertEquals(“http”, StringUtils.split(urlAddress, “:/”)[0]);
}
}
代码可读性比较：使用URL类更优雅
性能比较：URL类解析7s， StringUtils解析使用18s
why not URL class?
