如何在spring boot拦截器中从HttpServletReponse获取内容

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

public class CustomInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws Exception {
        // 在这里可以获取HttpServletRequest对象，并通过它获取请求的内容
        String requestURI = request.getRequestURI();
        System.out.println("Request URI: " + requestURI);
        
        // 返回true表示继续处理请求，返回false表示拦截请求
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
            ModelAndView modelAndView) throws Exception {
        // 在请求处理之后调用，可以对响应进行处理
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
            throws Exception {
        // 在请求完成之后调用，可以进行一些资源清理操作
    }
}
