String aPath = "/P/y/z/a/b/a/g/e.php";
String bPath = "/P/y/z/a/b/a/g/c.php";
情况的时候貌似不对。
代码可改成：
public String pathARelativePathB(String pathA, String pathB, int i) {
// A相对于B ../g/e.php
if (pathA.contains(pathB)) {
if (i == 1) {
return pathA.replaceAll(pathB + "/", "");
} else {
StringBuffer sb = new StringBuffer();
for (int j = 1; j < i; j++)
sb.append("../");
return sb.append(pathA.replaceAll(pathB + "/", "")).toString();
}
} else {
return pathARelativePathB(pathA, pathB.substring(0, pathB.lastIndexOf("/")), ++i);
}
}
