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 {
 
    @Override
    public 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 {
 
    @Autowired
    private RedisService redisService;
 
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws Exception {
        //获取token
        String token = request.getHeader("Authoritarian");
        log.info("-----------token:" + token);
 
        //token为空，则返回401
        if(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;
    }
 
    
 
    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
                           ModelAndView modelAndView) throws Exception {
 
    }
 
    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
            throws Exception {
 
    }
}
