springboot中server.main.web-application-type=reactive导致的拦截器不生效

1、问题

今天写了在springboot项目中写了一个拦截器但是不生效，代码中拦截器implements HandlerInterceptor，同时implements WebMvcConfigurer中将该拦截器添加进去了，但是打断点进不去，也就意味着代码没有生效

@Data
@Component
@ConfigurationProperties(prefix = "myapp")
public class WhiteIpProperties {private List<String> allowedIps;
}

IpAddressInterceptor

/*** 定义拦截器以及执行时候的业务代码*/
@Slf4j
@Component
public class IpAddressInterceptor implements HandlerInterceptor {@Autowiredprivate WhiteIpProperties whiteIpProperties;@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {String ipAddress = request.getRemoteAddr();List<String> allowedIps = whiteIpProperties.getAllowedIps();if (allowedIps.contains(ipAddress)) {return true;} else {log.info("该ip不在访问的白名单中:{}", ipAddress);response.sendError(HttpServletResponse.SC_FORBIDDEN);return false;}}
}

WebMvcConfig

/*** 用于注册拦截器*/
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {@Autowiredprivate IpAddressInterceptor ipAddressInterceptor;@Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(ipAddressInterceptor).addPathPatterns("/api/video/**", "/api/img/**").excludePathPatterns("/error");}
}

2、定位原因

spring:main:web-application-type: reactive

在这里插入图片描述

问了下ai
在这里插入图片描述
那就按照ai提示的重新写代码

3、修改后正确代码

将上面的WebMvcConfig、WebMvcConfig删除掉重写，
下面是修改后的正确的代码，因为我是只有一个就直接这样写了，后面有扩展多个的情况

import com.cao.config.WhiteIpProperties;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;
import org.springframework.web.server.WebFilter;
import org.springframework.web.server.WebFilterChain;
import reactor.core.publisher.Mono;import java.util.List;@Slf4j
@Component
public class IpAddressFilter implements WebFilter {@Autowiredprivate WhiteIpProperties whiteIpProperties;@Overridepublic Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {String reqestIp = exchange.getRequest().getRemoteAddress().getHostName();List<String> allowedIps = whiteIpProperties.getAllowedIps();// 判断请求ip是否在白名单中if (allowedIps.contains(reqestIp)) {// 允许访问return chain.filter(exchange);} else {// 拒绝访问log.info("该ip不在访问的白名单中:{}", reqestIp);exchange.getResponse().setStatusCode(HttpStatus.FORBIDDEN);return exchange.getResponse().writeWith(Mono.just(exchange.getResponse().bufferFactory().wrap("该ip不在访问的白名单中".getBytes())));}}
}
