spirng中读取文件

文件放在resource下

ClassPathResource classPathResource = new ClassPathResource("SqlConf.txt");
InputStream inputStream = classPathResource.getInputStream();

路由访问文件

访问时，ip:port/html/xxxx 即可

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry){

        registry.addResourceHandler("/html/**").addResourceLocations("file:/ft-web/src/main/resources/html2pdf/");
    }

    @Bean
    public HttpMessageConverter<String> responseBody(){
        return new StringHttpMessageConverter(StandardCharsets.UTF_8);
    }
}
