Question

I have an interceptor, and under a certain condition I want to send a string response to the browser and then halt execution completely.

How can I do this?

Answer 1

Override the preHandle method and return false if you want to stop execution.

@Override
public boolean preHandle(HttpServletRequest request,
        HttpServletResponse response, Object handler) throws Exception {
    response.getWriter().write("something");
    return false;
}
