如何在Spring Boot中初始化一个所有控制器都可以访问的全局方法

import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ModelAttribute;

@ControllerAdvice
public class GlobalControllerAdvice {
    
    @ModelAttribute("globalAttribute")
    public String globalAttribute() {
        return "This is a global attribute";
    }
}

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

@Controller
public class MyController {
    
    @GetMapping("/myEndpoint")
    public String myEndpoint(Model model) {
        String globalAttribute = (String) model.asMap().get("globalAttribute");
        // 对全局属性进行处理
        return "myView";
    }
}
