Java Spring Bean constructor how to get call stack, backtrace

Easy wasy to print Java call stack or backtrace:
Implement a function and throw an Exception.
Call the function in the place you want to know its backtrace or callstack
And Catch the Exception then
Call Exception.getStackTrace

class MyService {

    public static void f() throws Exception {
        throw new Exception();
    }

    void forTest() {
        try {
            f();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Via this solution, we can get Bean constructor call stack easily.
