配置文件中添加拦截器要拦截和要放过

interceptor:
  #拦截所有以api开头的请求 多个就用逗号隔开
  path-patterns: /api/**,/user/** 
  #放过这个请求
  exclude-path-patterns: /api/page/m

然后写一个拦截器类 ,主要重写第一个方法,做一下判断

/**
 * 内部调用接口拦截
 *
 * @author linnine
 */
@Slf4j
@Component
public class ApiInterceptor implements HandlerInterceptor {

    /**
     * 判断是否为内网访问
     * @param request
     * @param response
     * @param handler
     * @return
     */
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws IOException {
        if( ...判断条件,成功就通过)){
            return true;
        }
        log.info("判断不可通过,进行拦截,输出json");
        ServletOutputStream outputStream = response.getOutputStream();
        String resp = JsonUtil.toJsonStr(Result.failed(BizCode.PERMISSION_CHECK_FAILURE));
        outputStream.write(resp.getBytes());
        outputStream.flush();
        outputStream.close();
        return false;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
                           ModelAndView modelAndView) throws Exception {
        HandlerInterceptor.super.postHandle(request, response, handler, modelAndView);
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
            throws Exception {
        HandlerInterceptor.super.afterCompletion(request, response, handler, ex);

    }
}

写完拦截器,到拦截器配置类中添加

/**
 * 拦截器配置类

 * @author : linnine09

@Slf4j
@Configuration
@RequiredArgsConstructor
@RefreshScope
public class InterceptorConfig extends WebMvcConfigurationSupport {

    @Value("${interceptor.path-patterns}")
    private String[] pathPatterns;
    @Value("${interceptor.exclude-path-patterns}")
    private String[] excludePathPatterns;


    @Resource
    private ApiInterceptor apiInterceptor;


    @Override
    protected void addInterceptors(InterceptorRegistry registry) {
            log.info("pathPatterns={}", JsonUtil.toJsonStr(pathPatterns));
        registry.addInterceptor(apiInterceptor).addPathPatterns(pathPatterns)
            .excludePathPatterns(excludePathPatterns);
            //如果要配置多套,就另起一行
        registry.addInterceptor(apiHealthyInterceptor).addPathPatterns("/**");
        super.addInterceptors(registry);
    }

    /**
     * 解决swagger-ui.html访问不到问题
     *
     * @param registry
     */
    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations("classpath:/static/");
        registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
        super.addResourceHandlers(registry);
    }

}
