1. WebUploader的使用,引入css和js,css其实没什么用:
2. 定义上传框:
开始上传
3.相关jquery:
// 文件上传
jQuery(function() {
var $ = jQuery,
$list = $('#thelist'),
$btn = $('#ctlBtn'),
state = 'pending',
uploader;
uploader = WebUploader.create({
// 不压缩image
resize: false,
// swf文件路径
swf: '/js/Uploader.swf',
// 文件接收服务端。
server: 'http://webuploader.duapp.com/server/fileupload.php',
// 选择文件的按钮。可选。
// 内部根据当前运行是创建,可能是input元素,也可能是flash.
pick: '#picker'
});
// 当有文件添加进来的时候
uploader.on( 'fileQueued', function( file ) {
$list.append( '
'
' + file.name + '
' +'
等待上传...
' +'
});
// 文件上传过程中创建进度条实时显示。
uploader.on( 'uploadProgress', function( file, percentage ) {
var $li = $( '#'+file.id ),
$percent = $li.find('.progress .progress-bar');
// 避免重复创建
if ( !$percent.length ) {
$percent = $('
'
'
'
}
$li.find('p.state').text('上传中');
$percent.css( 'width', percentage * 100 + '%' );
});
uploader.on( 'uploadSuccess', function( file ) {
$( '#'+file.id ).find('p.state').text('已上传');
});
uploader.on( 'uploadError', function( file ) {
$( '#'+file.id ).find('p.state').text('上传出错');
});
uploader.on( 'uploadComplete', function( file ) {
$( '#'+file.id ).find('.progress').fadeOut();
});
uploader.on( 'all', function( type ) {
if ( type === 'startUpload' ) {
state = 'uploading';
} else if ( type === 'stopUpload' ) {
state = 'paused';
} else if ( type === 'uploadFinished' ) {
state = 'done';
}
if ( state === 'uploading' ) {
$btn.text('暂停上传');
} else {
$btn.text('开始上传');
}
});
$btn.on( 'click', function() {
if ( state === 'uploading' ) {
uploader.stop();
} else {
uploader.upload();
}
});
});
4. 这样就可以了,贴一下完整代码:html>
WebUploader开始上传
// 文件上传
jQuery(function() {
var $ = jQuery,
$list = $('#thelist'),
$btn = $('#ctlBtn'),
state = 'pending',
uploader;
uploader = WebUploader.create({
// 不压缩image
resize: false,
// swf文件路径
swf: '/js/Uploader.swf',
// 文件接收服务端。
server: 'http://webuploader.duapp.com/server/fileupload.php',
// 选择文件的按钮。可选。
// 内部根据当前运行是创建,可能是input元素,也可能是flash.
pick: '#picker'
});
// 当有文件添加进来的时候
uploader.on( 'fileQueued', function( file ) {
$list.append( '
'
' + file.name + '
' +'
等待上传...
' +'
});
// 文件上传过程中创建进度条实时显示。
uploader.on( 'uploadProgress', function( file, percentage ) {
var $li = $( '#'+file.id ),
$percent = $li.find('.progress .progress-bar');
// 避免重复创建
if ( !$percent.length ) {
$percent = $('
'
'
'
}
$li.find('p.state').text('上传中');
$percent.css( 'width', percentage * 100 + '%' );
});
uploader.on( 'uploadSuccess', function( file ) {
$( '#'+file.id ).find('p.state').text('已上传');
});
uploader.on( 'uploadError', function( file ) {
$( '#'+file.id ).find('p.state').text('上传出错');
});
uploader.on( 'uploadComplete', function( file ) {
$( '#'+file.id ).find('.progress').fadeOut();
});
uploader.on( 'all', function( type ) {
if ( type === 'startUpload' ) {
state = 'uploading';
} else if ( type === 'stopUpload' ) {
state = 'paused';
} else if ( type === 'uploadFinished' ) {
state = 'done';
}
if ( state === 'uploading' ) {
$btn.text('暂停上传');
} else {
$btn.text('开始上传');
}
});
$btn.on( 'click', function() {
if ( state === 'uploading' ) {
uploader.stop();
} else {
uploader.upload();
}
});
});
5. springboot采用MultipartFile接收,直接转换成输入流读取即可,以前我做的时候不懂先生成文件,再读取文件成输入流,如下:BufferedInputStream fileStream = new BufferedInputStream(file.getInputStream());
6. 代码如下:@PostMapping("/importExcel")
@ResponseBody
public ResultBean importExcel(@RequestParam("file") MultipartFile file) {
ResultBean resultBean = new ResultBean();
try {
BufferedInputStream fileStream = new BufferedInputStream(file.getInputStream());
Sheet sheet = new Sheet(1, 0);
List list = EasyExcelFactory.read(fileStream, sheet);
for (Object obj : list) {
System.out.println(obj);
}
} catch (Exception e) {
e.printStackTrace();
}
return resultBean;
}
7. 当然easyexcel需要引入依赖:
com.alibaba
easyexcel
1.1.2-beat1
8.excel模板:
9.解析结果:
