Extract json data from given string

Question

I am having a string something like this :

a.b.c.d.e = 
{"altImages":2,"available":1,"availableColorCount":3};

Now I only need to fetch :

{"altImages":2,"available":1,"availableColorCount":3}

What should be regex expression to extract that part from given string. Please help

My Try :

(?smi)a.b.c.d\\(.*\"e\"=(.*?)\\}\\);.*

But its not helping around.

Answer 1

尝试这个：

.+\s*=\s*({(?:.+:.+,?)+})(?=;)

Answer 2

You can use something like:

.*?\n(.*);

Here is the version with named groups:

String text = "a.b.c.d.e = \n{\"altImages\":2,\"available\":1,\"availableColorCount\":3};";
Pattern pattern = Pattern.compile(".*?\n(?<JSON>.*);");
Matcher matcher = pattern.matcher(text);

if (matcher.matches()) {
    System.out.println(matcher.group("JSON"));
}
