as shown in the above URL if we want to read the eid and ename then we can read them using the @RequestParam annotation

Let's see the example in STS

Directory Structure:

EmployeeController.java

package com.example.demo.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class EmployeeController {

    @GetMapping("/get")
    public String get(@RequestParam("eid") Integer id,@RequestParam String ename) {
        return id+"="+ename;
    }
}

Run the application

Test Using the Postaman or browser

@RequestParam("eid") Integer id

above we are taking "eid" in bracket because variable id is different from the url that we are giving in the url "http://localhost:8080/get?eid=1&ename=sam"

@RequestParam String ename

above we are not taking anything after @RequestParam inside bracket because

the variable name is similar to the query parameter.
