spring boot 2.x靜態資源會被攔截器攔截的解決方法

SpringBoot2.x攔截器的寫法：

自定義攔截器繼承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 {
        // 攔截代碼
        System.out.println("請求已經被攔截");
        return true;
    }
}

寫一個類實現WebMvcConfiguration，重寫addInterceptors方法

添加自定義的攔截器（addInterceptor）；

配置需要攔截的請求（addPathPatterns）；

配置排除攔截的請求（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：需要排除攔截的靜態資源路徑是static下面的目錄，試過直接用/static/**是不能能生效的；
