xhEditor struts2实现图片上传

2014-08-12 21:46 239 查看

xhEditor的环境搭建请参考http://blog.csdn.net/itmyhome1990/article/details/38422255,这时我们打开图片功能是没有上传按钮的

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

<script type="text/javascript">
$(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
}
})
</script>

<body>
<div align="center">
<textarea rows="20" cols="110" id="content"></textarea>
</div>
</body>

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

<struts>
<package name="build" extends="struts-default">
<action name="ImgUpload" method="imgUpload"
class="com.itmyhome.ImgUploadAction">
</action>
</package>
</struts>

效果如图：
