How Cool Request Transforms Java API Debugging and Performance Tracing

Cool Request is an IDEA plugin that not only sends basic HTTP requests but also offers powerful reflection calls, allowing developers to bypass interceptors and support annotations like @Scheduled and job frameworks such as xxl-job.

What is Cool Request

It provides interface debugging, method timing statistics, and the ability to invoke any class in the project, including third‑party libraries.

What is Trace

Trace can record the execution of any non‑java package, tracking method calls from the Controller layer down to configurable depths, with manual addition for interface‑based calls.

Automatic MyBatis Function Tracing

Trace can selectively follow MyBatis execution functions, showing SQL execution time (e.g., 7 ms) as illustrated.

Display Call Count

The left‑hand “+100” indicates a method was called 100 times, though per‑method duration is not yet measured.

Custom Timing Colors

Users can set a threshold (e.g., 5 ms) to highlight slower methods in red.

Script Environment Operations

Scripts can set request headers such as tokens, manipulate environment variables, and parse JSON responses using built‑in libraries like ObjectMapper.

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() + "");
}
