如何使用springboot将十六进制值解码为十进制值？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

import org.springframework.web.bind.annotation.*;

@RestController
public class HexToDecimalController {

    @RequestMapping(value = "/hex-to-decimal", method = RequestMethod.GET)
    public int hexToDecimal(@RequestParam("hex") String hex) {
        // 在这里编写将十六进制值解码为十进制值的逻辑
        int decimal = Integer.parseInt(hex, 16);
        return decimal;
    }
}

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
