SpringBoot实现图片上传demo&Nginx进行代理显示，linux系统教程视频

keepalive_timeout 65;

#gzip on;

server {
listen 80;
server_name localhost;

#charset koi8-r;

#access_log logs/host.access.log main;

#访问路径拼接 upload 访问本地绝对路径下的某图片
location /upload/ {
alias D:/images/;
autoindex on;
}

location / {
root html;
index index.html index.htm;
}

#error_page 404 /404.html;

redirect server error pages to the static page /50x.html

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}

proxy the PHP scripts to Apache listening on 127.0.0.1:80

#location ~ .php$ {

proxy_pass http://127.0.0.1;

#}

pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

#location ~ .php$ {

root html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param script_FILENAME /scripts$fastcgi_script_name; include fastcgi_params;

#}

deny access to .htaccess files, if Apache’s document root concurs with nginx’s one

#location ~ /.ht {

deny all;

#}
}

another virtual host using mix of IP-, name-, and port-based configuration

#server {

listen 8000; listen somename:8080; server_name somename alias another.alias; location / { root html; index index.html index.htm; }

#}

HTTPS server

#server {

listen 443 ssl; server_name localhost; ssl_certificate cert.pem; ssl_certificate_key cert.key; ssl_session_cache shared:SSL:1m; ssl_session_timeout 5m; ssl_ciphers HIGH:!aNULL:!MD5; ssl_prefer_server_ciphers on; location / { root html; index index.html index.htm; }

#}

}

配置好nginx.conf记得重启一下服务器。效果如图：

八、java后台代码

@RestController
public class FileController {

@PostMapping(value = “/fileUpload”)
public String fileUpload(@RequestParam(value = “file”) MultipartFile file) {
if (file.isEmpty()) {
System.out.println(“请选择图片”);
}
String fileName = file.getOriginalFilename(); // 文件名
String suffixName = fileName.substring(fileName.lastIndexOf("."));

// 后缀名
String filePath = “D:/images/”; // 上传后的路径
fileName = UUID.randomUUID() + suffixName; // 新文件名
File dest = new File(filePath + fileName);
if (!dest.getParentFile().exists()) {
dest.getParentFile().mkdirs();
}
try {
file.transferTo(dest);
} catch (IOException e) {
e.printStackTrace();
}
//返回图片名称
return fileName;
}
}

这里将图片上传至D:/images文件夹中，因为前面配置了nginx的缘故，我这里是在本地测试的，直接使用localhost/upload/+返回的图片名称就可以访问到了。

如果想要通过项目的地址外加端口号进行访问的话，可以配置一个资源映射路径。

@Configuration
public class MyWebMvcConfig implements WebMvcConfigurer {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/upload/**").addResourceLocations(“file:D:/images/”);
}
}

like this!

ry) {
registry.addResourceHandler("/upload/**").addResourceLocations(“file:D:/images/”);
}
}

like this!
