2024-08-27 02:21:07
文件上传依赖：
<!-- 文件上传组件 -->
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>${commons-fileupload.version}</version>
</dependency> <dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.6</version>
</dependency>
在springmvc配置文件中增加解析器：
<!--SpringMvc文件上传时,需要配置MultipartResolver处理器 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="UTF-8"></property>
<property name="maxUploadSize" value="10485760"></property>
</bean>
引入JS----jquery.form.js
<!--最基础jQuery.js都是基于这个 -->
<script type="text/javascript" src="${pageContext.request.contextPath}/resouces/jquery-1.11.3.min.js"></script>
<!-- 异步转换参数js -->
<script type="text/javascript" src="${pageContext.request.contextPath}/resouces/jqueryExt.js"></script>
<!-- 上传文件js -->
<script type="text/javascript" src="${pageContext.request.contextPath}/resouces/jquery.form.js"></script>
页面表单设置：
<!--form提交表单 -->
<form class="form-horizontal" id="form1" enctype="multipart/form-data"> <div class="row clearfix">
<div class="form-group">
<label class="col-sm-1 control-label">编号:</label>
<div class="col-md-2 column">
<!--编号 -->
<input type="hidden" id="Staff_ID" class="form-control" name="Staff_ID" placeholder="请输入">
<input type="text" id="Staff_No" class="form-control" readonly name="Staff_No" placeholder="">
</div> <label class="col-sm-1 control-label">工号:</label>
<div class="col-md-2 column">
<input type="text" id="Staff_Code" onblur="setStaffId()" class="form-control" name="Staff_Code" placeholder="请输入工号">
</div> <label class="col-sm-1 control-label">姓名:</label>
<div class="col-md-2 column">
<input type="text" id="Staff_Name" class="form-control" name="Staff_Name" placeholder="请输入姓名" >
<span class="required" id="sp1">*</span>
</div> </div>
</div> <div class="row clearfix">
<div class="form-group">
<label class="col-sm-1 control-label">用户名:</label>
<div class="col-md-2 column">
<input type="text" id="Staff_LoginName" class="form-control" name="Staff_LoginName" placeholder="请输入用户名">
<span class="required" id="sp3">*</span>
</div>
<label class="col-sm-1 control-label">密码:</label>
<div class="col-md-2 column">
<input type="password" id="Staff_Pass" class="form-control" name="Staff_Pass" placeholder="请输入密码">
</div>
<label class="col-sm-1 control-label">职称:</label>
<div class="col-md-2 column">
<input type="text" id="Staff_Title" class="form-control" name="Staff_Title" placeholder="请输入职称">

</div>
</div>
</div> <div class="row clearfix">
<div class="form-group">
<label class="col-sm-1 control-label">级别:</label>
<div class="col-md-2 column">
<input type="text" id="Staff_Level" class="form-control" name="Staff_Level" placeholder="请输入级别">
</div>
<label class="col-sm-1 control-label">图片:</label>
<div class="col-md-3 column">
<input type="file" name="goodsImage"/>
</div>
<label class="col-sm-1 control-label">状态:</label>
<div class="col-md-2 column">
<select class="form-control" name="Staff_Enable">
<option value="1">启用</option>
<option value="0">注销</option>
</select>
</div> </div>
</div> <input type="button" id="saveUploadOrUpdate" data-toggle='modal' data-target='#myModal' class="btn btn-primary" value="保存">
</form>
/* 上传文本图片和修改 */
$(document).on("click","#saveUploadOrUpdate",function(){
$("#form1").ajaxSubmit({
url:"userss/saveUploadOrUpdate",
type:"post",
contentType:"application/x-www-form-urlencoded; charset=utf-8",
dataType:"text",
success:function(data){
alert(data);
queryUsers(1);
}
});
});
控制器中实现文件上传：
/*添加内容上传图片和修改*/
@RequestMapping("/saveUploadOrUpdate")
public void saveTbGoods(@RequestParam("goodsImage") MultipartFile file,StaffInfo tb,HttpServletRequest request,HttpServletResponse response) throws IOException{
System.out.println("文件："+file+"参数："+tb);
response.setContentType("text/html;charset=utf-8");
PrintWriter out=response.getWriter();
String pathName=transfer(file, request);//调用上传文件transfer方法得到文件路径
tb.setStaff_Pic(pathName);//添加set文件路径到数据库
int i=userServices.saveOrUpdateStaffInfo(tb);
if(i>0){
out.print("添加成功!");//往前台打印text文本格式
}else{
out.print("添加失败!");
}
}
/*上传文件*/
private String transfer(MultipartFile file,HttpServletRequest request){
//获取目标文件要存放的目录的绝对路径
String path=request.getServletContext().getRealPath("/resouces/upload");
String fileName=file.getOriginalFilename();//获取原始的文件名
File tranFile=new File(path,fileName);//创建目标文件对象
if(!tranFile.exists()){//如果目录不存在
tranFile.mkdirs();//创建目录
}
try {
file.transferTo(tranFile);//文件上传
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} return request.getContextPath()+"/resouces/upload/"+fileName;
}
如何显示：
tr+="<td><img style=' width:90px; height:60px;' src='"+obj.Staff_Pic+"'/></td>";
jsp代码：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8" isELIgnored="false"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
