不允许的内容类型: Struts 2中的fileUpload
不允许的内容类型: Struts 2中的fileUpload
提问于 2014-08-29 18:35:46
我对Struts 2很陌生，并且尝试使用fileUpload拦截器。我正在附加我的所有代码层
(**FileUploadAction**):类动作
package com.caveofprogramming.actions;
import java.io.File;
import org.apache.struts2.convention.annotation.InterceptorRef;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Result;
import com.opensymphony.xwork2.ActionSupport;
public class FileUploadAction extends ActionSupport{
private File fileUpload;
private String fileUploadContentType;
private String fileUploadFileName;
public String getFileUploadContentType() {
return fileUploadContentType;
}
public void setFileUploadContentType(String fileUploadContentType) {
this.fileUploadContentType = fileUploadContentType;
}
public String getFileUploadFileName() {
return fileUploadFileName;
}
public void setFileUploadFileName(String fileUploadFileName) {
this.fileUploadFileName = fileUploadFileName;
}
public File getFileUpload() {
return fileUpload;
}
public void setFileUpload(File fileUpload) {
this.fileUpload = fileUpload;
}
@Action( value = "/fileUpload",
results={@Result(name="success",location="/success.jsp"),
@Result(name="error",location="/error.jsp"),
@Result(name="input",location="/error.jsp")
},
interceptorRefs={
@InterceptorRef(
params={"allowedTypes","image/jpeg,image/jpg,application/zip",
"maximumSize","1024000"},
value="fileUpload"
),
@InterceptorRef("defaultStack"),
@InterceptorRef("validation")
}
)
public String execute(){
try{
return SUCCESS;
} catch(Exception e){
return ERROR;
}
}
public String display() {
return NONE;
}
}error.jsp**:**
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<body>
<s:fielderror/>
</body>
</html> Success.jsp**:**
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
Success
</body>
</html>fileUpload.jsp**:**
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<s:head />
</head>
<body>
<h1>Struts 2 <s:file> file upload example</h1>
<s:form method="post" enctype="multipart/form-data" action="fileUpload">
<s:file label="File One" name="fileUpload" />
<s:submit />
</s:form>
</body>
</html>我不明白为什么我会犯这个错误
"Content-Type not allowed: fileUpload "photography-104a.jpg" "upload_37fbf440_169b_4687_af65_93c8c967256c_00000000.tmp" image/pjpeg"虽然我上传的文件格式是.jpg。

可能是因为不允许内容类型为image/pjpeg的文件出现此错误。使用fileUpload拦截器参数定义允许的MIME类型
<interceptor-ref name="fileUpload">
<param name="allowedTypes">image/jpeg,image/pjpeg</param>
</interceptor-ref> 页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
