如何在spring-boot过滤器中获取自定义注释

import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import java.io.IOException;
import java.lang.reflect.Method;

@WebFilter(urlPatterns = "/*")
public class CustomFilter implements Filter {

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        // 过滤器初始化方法
    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)
            throws IOException, ServletException {
        // 过滤器处理方法
        // 获取目标类的注释
        Class<?> targetClass = servletRequest.getClass();
        CustomAnnotation classAnnotation = targetClass.getAnnotation(CustomAnnotation.class);
        if (classAnnotation != null) {
            // 获取注释的属性值
            String classValue = classAnnotation.value();
            System.out.println("Class Annotation Value: " + classValue);
        }

        // 获取目标方法的注释
        try {
            Method method = targetClass.getMethod("doFilter", ServletRequest.class, ServletResponse.class,
                    FilterChain.class);
            CustomAnnotation methodAnnotation = method.getAnnotation(CustomAnnotation.class);
            if (methodAnnotation != null) {
                // 获取注释的属性值
                String methodValue = methodAnnotation.value();
                System.out.println("Method Annotation Value: " + methodValue);
            }
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }

        // 继续执行过滤链
        filterChain.doFilter(servletRequest, servletResponse);
    }

    @Override
    public void destroy() {
        // 过滤器销毁方法
    }
}
