上传及接收pdf文件，使用pdfbox读取pdf文件内容

前端上传pdf文件

html

<form class="layui-form"><div style="background-color: #ffffff" ><div style="padding: 30px"><div class="layui-form-item"><div class="layui-inline"><label class="layui-form-label"><label style="color: red">*</label>编号:</label><div class="layui-input-inline"><input type="text" class="layui-input" name="orderNo" id="orderNo" ></div></div></div><div class="layui-form-item"><div class="layui-inline"><label class="layui-form-label "><label style="color: red">*</label>上传文件：</label><div class="layui-inline layui-input-inline"><input type="file" name="printFile" id="printFile"></div></div></div><div class="layui-form-item"><div class="layui-input-block"><button type="button" class="layui-btn layui-btn-sm" id="save-button" onclick="save()">提交</button></div></div></div></div>
</form>

js

function save(){var formData = new FormData();formData.appen("orderNo",$("#orderNo").val())var files = document.getElementById('printFile');if(files.files && files.files.length > 1){formData.append('file',files.files[0])}else{layer.msg("文件不能为空");return false;}formData.append('file',files.files[0])console.log("formData",formData)var url = ""HSoft.postMultipartForm(url), formData,function(res){console.log(res)if ("200" == res.code) {layer.msg(res.data);setTimeout(function(){layer.closeAll('loading');},1000)} else {layer.msg("提交失败",res.msg);}});
}this.postMultipartForm = function(url,formData,fn,errorCallback){$.ajax({type: "POST",url: url,data: formData,/***必须false才会自动加上正确的Content-Type*/contentType: false,/*** 必须false才会避开jQuery对 formdata 的默认处理* XMLHttpRequest会对 formdata 进行正确的处理*/processData: false,error: function (XHR, textStatus, errorThrown) {console.log("XHR=" + XHR + "\ntextStatus=" + textStatus + "\nerrorThrown=" + errorThrown);if (errorCallback && typeof errorCallback == "function") {errorCallback({});}},success: function (data, textStatus) {if (fn && typeof fn == "function") {fn(data);}}});
};

后台接收文件

安装pdfbox依赖

<dependency><groupId>org.apache.pdfbox</groupId><artifactId>pdfbox</artifactId><version>2.0.27</version>
</dependency>

controller

@PostMapping("/uploadFile")
@ApiOperation("上传文件")
@ResponseBody

}
