自己的經驗是不能和正常的正規表達式一起混用。
代碼如下：是不能正确判斷的
public class Test {
public static void main(String[] args) {
String url ="http://so.xywy.com/zonghe.php?keyword=ganmao=2page";
String PdReg= "http://so.xywy.com/(zonghe|yisheng).php[?]keyword=.*^(?!.*page).*";
Pattern p1 = Pattern.compile(PdReg);
Matcher m = p1.matcher(url);
System.out.println(m.matches());
}
}
代碼如下：結果是可以得
public class Test {
public static void main(String[] args) {
String url ="http://so.xywy.com/zonghe.php?keyword=ganmao=2page";
String PdReg= "http://so.xywy.com/(zonghe|yisheng).php[?]keyword=.*";
//^(?!.*page).*
Pattern p1 = Pattern.compile(PdReg);
Matcher m = p1.matcher(url);
System.out.println(m.matches());
}
}
代碼如下：結果是可以得
public class Test {
public static void main(String[] args) {
String url ="http://so.xywy.com/zonghe.php?keyword=ganmao=2page";
String PdReg= "^(?!.*page).*";
//http://so.xywy.com/(zonghe|yisheng).php[?]keyword=.*
Pattern p1 = Pattern.compile(PdReg);
Matcher m = p1.matcher(url);
System.out.println(m.matches());
}
}
結論是兩種形式不能混用
