How to set baseURI, basePath, and basePort in Rest Assured?

import io.restassured.RestAssured;
import org.testng.annotations.BeforeClass;

public class BaseTest {

    @BeforeClass
    public void setupRestAssured() {

        // Base URI — the scheme and host
        RestAssured.baseURI = "https://reqres.in";

        // Base Path — common path prefix
        RestAssured.basePath = "/api";

        // Base Port — if not default (80/443)
        RestAssured.port = 8080; // only needed for non-standard ports

        // SSL relaxation (for test environments with self-signed certs)
        RestAssured.useRelaxedHTTPSValidation();
    }
}

@Test
public void testGetUser() {
    // Full URL: https://reqres.in/api/users/2
    given()
        .when()
        .get("/users/2")   // ← only relative path needed
        .then()
        .statusCode(200);
}

@Test
public void testCreateUser() {
    // Full URL: https://reqres.in/api/users
    given()
        .body("{ \"name\": \"John\" }")
        .contentType(ContentType.JSON)
        .when()
        .post("/users")    // ← only relative path
        .then()
        .statusCode(201);
}

// config.properties
base.url=https://api.staging.com
base.path=/api/v2
port=443

// BaseTest.java
@BeforeClass
public void setup() {
    RestAssured.baseURI  = ConfigManager.get("base.url");
    RestAssured.basePath = ConfigManager.get("base.path");
    RestAssured.port     = Integer.parseInt(ConfigManager.get("port"));
}

@AfterClass
public void teardown() {
    RestAssured.reset(); // Resets all static defaults
}
