spring框架限制接口是否要登录过才能访问

1、引入spring 、spring boot依赖，这部分不再多说，正常开发spring boot项目就可以。

2、定义类，实现WebMvcConfigurer接口

package com.hmblogs.config;import com.hmblogs.config.web.interceptor.PortalTokenInterceptor;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;@Configuration
public class InterceptorConfig implements WebMvcConfigurer {@Overridepublic void addInterceptors(InterceptorRegistry registry) {PortalTokenInterceptor tokenInterceptor = (PortalTokenInterceptor) SpringFactory.getBean("portalTokenInterceptor");InterceptorRegistration tokenRegistration = registry.addInterceptor(tokenInterceptor);tokenRegistration.addPathPatterns("/**");tokenRegistration.excludePathPatterns("/swagger-ui.html").excludePathPatterns("/doc.html").excludePathPatterns("/swagger-ui.html/**").excludePathPatterns("/swagger**").excludePathPatterns("/**/swagger**").excludePathPatterns("/configuration/ui").excludePathPatterns("/**/configuration/ui").excludePathPatterns("/swagger-resources").excludePathPatterns("/**/swagger-resources").excludePathPatterns("/configuration/security").excludePathPatterns("/**/configuration/security").excludePathPatterns("/v2/api-docs").excludePathPatterns("/error").excludePathPatterns("/webjars/**").excludePathPatterns("/**/favicon.ico").excludePathPatterns("/login/**").excludePathPatterns("/v3/secStaff/checkUserExistByEmail").excludePathPatterns("/v3/secStaff/register").excludePathPatterns("/v3/secStaff/sendVerifyCode").excludePathPatterns("/v3/secStaff/checkEmail").excludePathPatterns("/v3/secStaff/checkPhone").excludePathPatterns("/v3/secStaff/checkVerifyCode");}}

3、定义拦截器，实现HandlerInterceptor接口

package com.blogs.config.web.interceptor;import cn.hutool.core.date.DateTime;
import cn.hutool.core.date.DateUnit;
import cn.hutool.core.date.DateUtil;
import cn.hutool.http.HttpStatus;
import cn.hutool.json.JSONUtil;import com.alibaba.fastjson.JSON;
import liquibase.util.MD5Util;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.time.Duration;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;@Slf4j
@Component
public class PortalTokenInterceptor implements HandlerInterceptor {@Autowiredprivate RedisService redisService;@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)throws Exception {//获取tokenString token = request.getHeader("Authoritarian");log.info("-----------token:" + token);//token为空，则返回401if(StringUtils.isEmpty(token)) {response.setStatus(HttpStatus.HTTP_UNAUTHORIZED);response.setContentType("application/json");response.setCharacterEncoding("utf-8");response.getWriter().print(JSONUtil.toJsonStr(RestResponse.failed(ResultCode.UN_AUTHORIZED, "认证失败")));return false;}return true;}@Overridepublic void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,ModelAndView modelAndView) throws Exception {}@Overridepublic void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)throws Exception {}
}
