如何将来自RestController的结果添加到Spring中的自定义包装器对象

// Step 1: 创建自定义包装器对象
public class CustomWrapper {
    private Object result;

    public Object getResult() {
        return result;
    }

    public void setResult(Object result) {
        this.result = result;
    }
}

// Step 2: 编写拦截器
public class CustomInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        // 在请求处理之前执行的逻辑，可以不进行任何处理
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        // 在请求处理之后执行的逻辑，将结果添加到自定义包装器对象中
        CustomWrapper wrapper = new CustomWrapper();
        wrapper.setResult(modelAndView.getModel().get("result")); // 假设结果存储在名为result的模型中
        modelAndView.addObject("customWrapper", wrapper); // 将包装器对象添加到模型中
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
        // 在视图渲染之后执行的逻辑
    }
}

// Step 3: 注册拦截器
@Configuration
public class WebConfig implements WebMvcConfigurer {

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new CustomInterceptor());
    }
}
