阿新 • • 發佈：2018-12-16
一、pom.xml
<!--引用springMVC依賴--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.1.0.RELEASE</version> </dependency> <!--引用上傳與下載依賴--> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.3</version> </dependency>
二、springmvc-config.xml
<!-- 檔案上傳配置，這裡id的名稱固定寫法 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"></bean>三、FileController.java
package cn.kaxlm6.mybatis.controller; import org.apache.logging.log4j.LogManager; import org.apache.logging.log4j.Logger; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.util.FileCopyUtils; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.multipart.MultipartFile; import javax.servlet.ServletContext; import javax.servlet.http.HttpServletRequest; import java.io.File; import java.util.Calendar; /** * Created by IntelliJ IDEA. * * @author xlm * description: * path: mybatisProject-cn.kaxlm6.mybatis.controller-FileController * date: 2018/10/19 16:48 * version: 02.06 * To change this template use File | Settings | File Templates. */ @Controller public class FileController { Logger logger = LogManager.getLogger(); @Autowired ServletContext context; @RequestMapping(value = "/fileUpload", method = RequestMethod.POST) public void fileUpload(@RequestParam("uploadFile") MultipartFile[] file, HttpServletRequest request) throws Exception { for (int i = 0; i < file.length; i++) { //判斷檔案是否為空 if (!file[i].isEmpty()) { //獲得原檔名 String fileName = file[i].getOriginalFilename(); //File.separator表示在 UNIX 系統上，此欄位的值為 /；在 Windows 系統上，它為 \，如：C:\tmp\test.txt和tmp/test.txt String filePath = context.getRealPath("") + "upload" + File.separator; //獲得當前日期 Calendar ca = Calendar.getInstance(); //拼接日期資料夾 filePath += ("" + ca.get(Calendar.YEAR) + (ca.get(Calendar.MONTH) + 1) + ca.get(Calendar.DATE)); File dateDir = new File(filePath); //判斷當前日期資料夾是否存在，不存在建立 if (!dateDir.exists()) { dateDir.mkdirs(); } //檔名由客戶端IP地址+系統當前毫秒陣列成 filePath += File.separator + request.getRemoteAddr().replace(":", "") + System.currentTimeMillis() + fileName.substring(fileName.lastIndexOf(".")); // 複製本地檔案到伺服器 FileCopyUtils.copy(file[i].getBytes(), new File(filePath)); } else { logger.info("檔案上傳異常"); } } } }
四、index.jsp
