spring boot 2.x静态资源会被拦截器拦截的解决方法

SpringBoot2.x拦截器的写法：

自定义拦截器继承HandlerInterceptorAdapter

import org.springframework.stereotype.Component;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

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

@Component
public class AuthInterceptor extends HandlerInterceptorAdapter {
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        // 拦截代码
        System.out.println("请求已经被拦截");
        return true;
    }
}

写一个类实现WebMvcConfiguration，重写addInterceptors方法

添加自定义的拦截器（addInterceptor）；

配置需要拦截的请求（addPathPatterns）；

配置排除拦截的请求（excludePathPatterns）；

import com.sunruofei.gmall.interceptors.AuthInterceptor;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

import javax.annotation.Resource;

@Configuration
public class WebMvcConfiguration implements WebMvcConfigurer {

    @Resource
    AuthInterceptor authInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry){
        registry.addInterceptor(authInterceptor).addPathPatterns("/**").excludePathPatterns("/error","/bootstrap/**","/css/**","/image/**","/img/**","/js/**","/scss/**");
    }
}

注意：需要排除拦截的静态资源路径是static下面的目录，试过直接用/static/**是不能能生效的；
