springboot简单的token验证

启动类添加组件扫描注解

@SpringBootApplication
// 扫描组件
@ServletComponentScan
public class WarningForecastApplication {

    public static void main(String[] args) {
        SpringApplication.run(WarningForecastApplication.class, args);
    }
}

定义token拦截器

package com.aliyun.warningforecast.interceptor;

import lombok.extern.slf4j.Slf4j;
import org.springframework.util.StringUtils;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**

 */

@Slf4j
public class TokenVerificationInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

        String token = request.getHeader("token");
        log.info("访问前拦截请求，从请求头中获取token ---> " + token);
        if (StringUtils.isEmpty(token)) {
            log.info("token为空，请携带正确的token");
            return false;
        }
        if (token.equals("123")) {
            log.info("token验证成功");
            return true;
        }
        return false;
    }

    @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 {

    }
}

注册token拦截器

package com.aliyun.warningforecast.config;

import com.aliyun.warningforecast.interceptor.TokenVerificationInterceptor;
import org.springframework.boot.context.properties.ConfigurationProperties;
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.WebMvcConfigurationSupport;

import java.util.ArrayList;
import java.util.List;

@Configuration
@ConfigurationProperties(prefix = "interceptor.config.path")
public class InterceptorConfig extends WebMvcConfigurationSupport {

    private List<String> special = new ArrayList<>();

    public List<String> getSpecial() {
        return special;
    }

    public void setSpecial(List<String> special) {
        this.special = special;
    }

    @Override
    protected void addInterceptors(InterceptorRegistry registry) {

        InterceptorRegistration interceptor = registry.addInterceptor(new TokenVerificationInterceptor());

        interceptor.addPathPatterns(special);
    }
}

配置文件配置

# 拦截器配置路径
interceptor.config.path.special=/api/v0.1/**
