Web请求拦截器

1. 实现HandlerInterceptor；

@Component

public class HttpInterceptor implements HandlerInterceptor {}

2. 添加到拦截器链中；

@Component

public class WebMvcConfig implements WebMvcConfigurer {

@Autowired

    private HttpInterceptor httpInterceptor;

@Override

    public void addInterceptors(InterceptorRegistry registry) {

registry.addInterceptor(httpInterceptor);

}
