场景现象

如果想报表名或描述保存为中文时会发生如下错误：

提示错误：

1 2	ERRORS: The field Description must be an alphanumeric string (letters and numbers with other character such as parenthesis and -_;:!?,.\/)

只能输入字母数字及某些特殊字符的组合。
查询源代码：

9016 = The field %0 must be an alphanumeric string (letters and numbers with other character such as parenthesis and -_;:!?,./)

ERROR_EXTENDED_ALFANUMERIC="9016";

一、重置验证

页面代码：

knowage\src\main\webapp\WEB-INF\conf\analiticalmodel\documentBrowser.xml

验证规则：
knowage\src\main\webapp\WEB-INF\conf\analiticalmodel\validation.xml

重置验证：

<FIELD name="name" label="#SBIDev.docConf.docDet.nameField">
	<VALIDATOR validatorName="MANDATORY"/>
	<!-- <VALIDATOR validatorName="EXTENDED_ALFANUMERIC"/> ranying -->
	<VALIDATOR validatorName="MAXLENGTH" arg0="200"/>
</FIELD>
<FIELD name="description" label="#SBIDev.docConf.docDet.descriptionField">
	<!-- <VALIDATOR validatorName="EXTENDED_ALFANUMERIC"/> ranying -->
	<VALIDATOR validatorName="MAXLENGTH" arg0="400"/>
</FIELD>

重置之后可以保存了但内容是乱码：

二、修复乱码

跟踪代码发现在验证之前就已经是乱码了，

请求链路：
1.it.eng.spago.dispatching.httpchannel.AdapterHTTP

DetailBIObjectModule
- Service
- handleMultipartForm(request, requestContext);
- modBIObject

问题就在handleMultipartForm方法，原因是使用common-fileupload解析字段内容但使用的默认编码格式,改为使用UTF-8格式读取字段内容。

private void handleMultipartForm(HttpServletRequest request, RequestContextIFace requestContext)
    	throws Exception{
    	SourceBean serviceRequest = requestContext.getServiceRequest();

    	// Create a factory for disk-based file items
    	FileItemFactory factory = new DiskFileItemFactory();

    	// This is done to make upload work in Unix solaris
    	//((DiskFileItemFactory)factory).setSizeThreshold(5242880);

    	// Create a new file upload handler
    	ServletFileUpload upload = new ServletFileUpload(factory);

    	//upload.setFileSizeMax(5242880);
    	//upload.setSizeMax(5242880);


        // Parse the request
        List fileItems = upload.parseRequest(request);
        Iterator iter = fileItems.iterator();
        while (iter.hasNext()) {
            FileItem item = (FileItem) iter.next();

            if (item.isFormField()) {
                String name = item.getFieldName();
                // Support all characters . by ranying
                String value = item.getString("utf-8");
                serviceRequest.setAttribute(name, value);
            } else {
                processFileField(item, requestContext);
            }
        }
    }
