springBoot自定义拦截器

编写FuelH5InterceptorConfig配置类

package com.fuel.framework.config;

import com.fuel.framework.interceptor.FuelH5Interceptor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

/**
 * 通用配置
 * 
 * @author hhxx
 */
@Configuration
public class FuelH5InterceptorConfig implements WebMvcConfigurer
{
    @Autowired
    private FuelH5Interceptor fuelH5Interceptor;

    /**
     * 自定义拦截规则
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry)
    {
        registry.addInterceptor(fuelH5Interceptor)
                .addPathPatterns("/api/wx/**")    //拦截所有请求 通过判断token是否合法来决定是否访问
                .addPathPatterns("/api/personal/**")
                .addPathPatterns("/api/scan/**")
                .excludePathPatterns("/api/wx/getToken")
                .excludePathPatterns("/api/scan/login")
                .excludePathPatterns("/api/scan/wxCallBackInfo");
    }

}
