如何使用SpringBoot在地图中加载属性？

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

map.api.key=your_map_api_key
map.default.zoom=10

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MapConfig {
    @Value("${map.api.key}")
    private String mapApiKey;

    @Value("${map.default.zoom}")
    private int defaultZoom;

    // 其他地图相关配置...
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class MapController {
    private final MapConfig mapConfig;

    @Autowired
    public MapController(MapConfig mapConfig) {
        this.mapConfig = mapConfig;
    }

    @GetMapping("/map")
    public String showMap(Model model) {
        model.addAttribute("apiKey", mapConfig.getMapApiKey());
        model.addAttribute("defaultZoom", mapConfig.getDefaultZoom());
        // 其他地图相关操作...
        return "map";
    }
}
