android struts2 图片上传,xhEditor struts2实现图片上传

如果想要出现上传按钮,在xhEditor设置以下参数：

html5Upload : false                     //此属性必须为false

upImgUrl : "ImgUpload.action" //上传服务器接口

onUpload : insertUpload            //服务器返回信息,JSON格式

一、前台代码

$(function() {

$('#content').xheditor( {

tools : 'full', //也可自定义tools,这里为full

html5Upload : false, //此属性必须为false 否则无法上传图片

upImgUrl : "ImgUpload.action",

onUpload : uploadImg

});

function uploadImg(data) {

//...回调函数

}

})

二、Struts2上传代码

public class ImgUploadAction extends ActionSupport {

private String err = "";

private String msg; //返回信息

private File filedata; //上传文件

private String filedataFileName; //文件名

public String imgUpload() {

//获取response、request对象

ActionContext ac = ActionContext.getContext();

HttpServletResponse response = (HttpServletResponse) ac.get(ServletActionContext.HTTP_RESPONSE);

HttpServletRequest request = (HttpServletRequest) ac.get(ServletActionContext.HTTP_REQUEST);

response.setContentType("text/html;charset=gbk");

PrintWriter out = null;

try {

out = response.getWriter();

} catch (IOException e1) {

e1.printStackTrace();

}

String saveRealFilePath = ServletActionContext.getServletContext().getRealPath("/upload");

File fileDir = new File(saveRealFilePath);

if (!fileDir.exists()) { //如果不存在 则创建

fileDir.mkdirs();

}

File savefile;

savefile = new File(saveRealFilePath + "/" + filedataFileName);

try {

FileUtils.copyFile(filedata, savefile);

} catch (IOException e) {

err = "错误"+e.getMessage();

e.printStackTrace();

}

String fileName = request.getContextPath() + "/upload/" + filedataFileName;

msg = "{"err":"" + err + "","msg":"" + fileName + ""}";

out.print(msg); //返回msg信息

return null;

}

public String getErr() {

return err;

}

public void setErr(String err) {

this.err = err;

}

public String getMsg() {

return msg;

}

public void setMsg(String msg) {

this.msg = msg;

}

public File getFiledata() {

return filedata;

}

public void setFiledata(File filedata) {

this.filedata = filedata;

}

public String getFiledataFileName() {

return filedataFileName;

}

public void setFiledataFileName(String filedataFileName) {

this.filedataFileName = filedataFileName;

}

}三、Struts2配置文件

class="com.itmyhome.ImgUploadAction">

效果如图：
