效果:

1. jar包导入:

代码语言:javascript复制
<!-- 文件上传组件 -->
		<dependency>
			<groupId>commons-fileupload</groupId>
			<artifactId>commons-fileupload</artifactId>
			<version>1.3.1</version>
		</dependency>

2. 在spring的配置文件中加上:

代码语言:javascript复制
<!-- 支持文件上传 -->
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    	 <!-- 请求编码格式 -->
    	 <property name="defaultEncoding" value="utf-8"></property>
    	 <!-- 上传文件大小(单位:字节) -->
         <property name="maxUploadSize" value="50000000"></property>
         <!-- 缓冲区大小(单位:KB) -->
         <property name="maxInMemorySize" value="1024"></property>
    </bean>

3. 从官网上下载可用的版本解压后添加到项目中,webapp下位置任意:

		_logger.info("+++++++++++++++++++++++ 执行修改头像  操作 +++++++++++++++++++++++ ");
		
		File targetFile;
		// 存储路径
        String msgUrl = "";
        // 是否上传成功标志
        boolean flag = false;
        // 取图片的原始名称、后缀
        String fileName = uploadFile.getOriginalFilename();
        if(fileName != null && fileName != ""){
