    System.out.println(matcher.group(1));

Answer 1

String filename = filepath.substring(filepath.lastIndexOf("\\") + 1);

或（没试过，看起来有点奇怪）

String filename = filepath.substring(filepath.lastIndexOf("\\", "images\\".length()) + 1);

Answer 2

String string = "http:\localhost:9090\ZenoBusinessStore\images\integration-icon.png";
int index = string.indexOf("images\\");
String output = string.substring(index);

Answer 3

String text = "http:\localhost:9090\SpringMVC\images\integration-icon.png"
String subText = text.subString(text.indexOf("\images"), text.length());
System.out.println(subText);

Answer 4

String in = "http:\\localhost:9090\\ZenoBusinessStore\\images\\integration-icon.png";
String op = in.replace("http:\\localhost:9090\\ZenoBusinessStore", "");
System.out.println(op);

Answer 5

ZenoBusinessStore must be the name of your project which is constant. Now split the string

String s = "http:\localhost:9090\ZenoBusinessStore\images\integration-icon.png";
String ary = s.split("ZenoBusinessStore");

Now the 2nd element of the array is your image path.

 System.out.println(ary[1]);

Answer 6

Use '\\\\'. It's because backslash is used in escape sequence like '\\n'. With a single \\ the compiler have no way to know.
