配置拦截接口

@Configuration
public class InterceptorConfig implements WebMvcConfigurer {
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new LoginInterceptor())
                //添加拦截的路径
                .addPathPatterns("/FileUpload/upload")
                //排除拦截路径
                .excludePathPatterns("/register/*","/jwt/token","/jwt/checkJWT");
    }
}
