New Features of Cool Request Plugin: Trace, MyBatis Tracking, Custom Timing Colors, and Scripting

Introduction: The article introduces the latest update of the Cool Request plugin for IntelliJ IDEA, which now supports method execution time statistics and various tracing capabilities.

What is Cool Request: It is an interface debugging plugin that can send HTTP requests, perform reflection calls, bypass interceptors, and invoke methods annotated with @Scheduled or managed by xxl‑job.

Trace feature: The Trace function can track execution of any non‑java package methods, with configurable depth (1‑3). Depth 1 tracks only controller methods, depth 2 includes methods called by the controller, and depth 3 follows deeper calls, with manual addition possible for interface‑based calls.

MyBatis function tracking: Trace can selectively monitor MyBatis execution functions, allowing users to see query durations such as 7 ms.

Call count display and custom timing colors: The UI shows a "+100" indicator for the number of calls under a method, and users can set a threshold (e.g., 5 ms) to highlight methods exceeding that duration in red.

Scripting environment: Scripts can set request headers (e.g., token) and manipulate environment variables, making it easy to handle authentication. Responses are often JSON, which can be parsed using built‑in libraries like ObjectMapper or Gson .

Code example:

public void handlerResponse(ILog log, HTTPResponse response, IEnv env) {
    String body = new String(response.getResponseBody());
    log.println(body);
    User user = JSON.parseObject(body, User.class);
    log.println(user.getAge()+"");
}
