这是我的dropzone.js文件上传表
<form action="admin/rest/import/customers" class="dropzone" enctype="multipart/form-data"></form>
我已经故意在我的表单中添加了多部分/表单数据,但是当我在上传时检查流程时,内容类型是content-type:multipart/form-data;边界=----WebKitFormBoundaryG1ZnT8kA25wpWLdW
. 上传excel文件时如何修复415错误,它显示了415错误。我错过了什么来添加Java代码?请帮忙。谢谢。对于Jersey,您必须做两件事:
寄存器(MultiPartFeature.class)代码>到您的ResourceConfig
importCustomersExcel(InMultiPart inMP)
更改为
importcustomersecel(@FormDataParam(“文件”)InputStream流,@FormDataParam(“文件”)formdatacontentdispositionfiledetail)
然后,您可以通过
stream
访问文件内容,并通过fileDetail
访问文件详细信息。还要确保您的Dropzone参数名是文件
尝试更改您的方法参数以匹配此处的参数:@HalkoKarr Sajtarevic,我的方法哪里出错了?哦-刚刚看到您使用的是jersey而不是spring-对不起,我的错误!在何处添加寄存器(MultiPartFeature.class);您必须将其放入类的构造函数中,该类正在扩展ResourceConfig
谢谢。在这种情况下,我仍然在学习Java和所有东西。再次感谢。
