springboot项目从硬盘指定位置读取文件(获取静态资源)

方法一：继承WebMvcConfigurerAdapter类

package com.imooc.demo.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
public class FileStaticConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {

        /**
         *  /source/xxx   指文件的访问方式  如：localhost:8080/source/abc.wav
         *  file:d/voice/  指静态文件存放在服务器上的位置
         */
        registry.addResourceHandler("/source/**").addResourceLocations("file:"+"d:/voice/");
    }
}

　　

方法二、

在SpringBoot2.0及Spring 5.0 WebMvcConfigurerAdapter已被废弃

官方推荐WebMvcConfigurer，代码如下：

package com.imooc.demo.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
public class FileStaticConfig implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        
        /**
         *  /source/xxx   指文件的访问方式  如：localhost:8080/source/abc.wav
         *  file:d/voice/  指静态文件存放在服务器上的位置
         */
        registry.addResourceHandler("/source/**").addResourceLocations("file:"+"d:/voice/");
    }
}
