1.控制器加载视图文件
package masterSpringMvc.Controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class UploadController
{
@RequestMapping("/upload/")
public String upload()
{
return "upload";
}
}
2.视图文件实现一个基本的表单
<!DOCTYPE HTML>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org" >
<head>
<meta content="text/html;charset=UTF-8"/>
<title>hello</title>
</head>
<body>
upload page
<br>
<form th:action="@{/upload/}" method="post" enctype="multipart/form-data">
<input type="file" name="upload_file" />
<button type="submit" name="save" th:text="#{submit}"></button>
</form>
</body>
</html>
3.建立I18N
messages_zh_CN.properties messages.properties
4.固化语言
applicatoin.properties spring.mvc.locale=zh_CN spring.mvc.locale-resolver=FIXED
5.处理POST保存图片
package masterSpringMvc.Controller;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import org.apache.tomcat.util.http.fileupload.IOUtils;
import org.springframework.core.io.FileSystemResource;
import org.springframework.core.io.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.multipart.MultipartFile;
@Controller
public class UploadController
{
public static final Resource PICTURES_DIR = new FileSystemResource("./pictures");
@RequestMapping("upload")
public String upload()
{
return "upload";
}
@RequestMapping(value="/upload",method=RequestMethod.POST)
public String onUpload(MultipartFile file) throws IOException
{
String filename = file.getOriginalFilename();
File tempFile = File.createTempFile("pic", getFileExtension(filename),PICTURES_DIR.getFile());
try(InputStream in = file.getInputStream();OutputStream out = new FileOutputStream(tempFile))
{
IOUtils.copy(in, out);
}
return "upload";
}
private static String getFileExtension(String name)
{
return name.substring(name.lastIndexOf("."));
}
}
