struts 1.2 整合 spring时getServlet() 为空

[什么都不能]

<action path="/upload" type="org.springframework.web.struts.DelegatingActionProxy" scope="request" >
</action>


<bean name="/upload" class="com.test.struts.action.UploadAction" singleton="false"></bean>

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception{
UploadForm f = (UploadForm) form;
FormFile file=f.getAttachment();
byte[] data=file.getFileData();

49: String filePath=getServlet().getServletContext().getRealPath("/upload");
System.out.println(filePath);
FileOutputStream fo=new FileOutputStream(filePath+"/"+file.getFileName());
fo.write(data);
int size=file.getFileSize();
String type=file.getContentType();
Map mp=new HashMap();
mp.put("size", size);
mp.put("type",type);
request.setAttribute("property", mp);
return new ActionForward("/result.jsp");
}
49行报NullPointerException

getServlet().getServletContext()? 啥意思啊？？

[never2cry]

The ServletContext object is contained within the ServletConfig object, which the Web server provides the servlet when the servlet is initialized.

调试下到底是getServlet()为null还是后面的...

[miaoliujun]

是不是没有upload文件夹？

建議將49行代碼,拆分調試.

[什么都不能]

拆分测试结果，用DelegetingActionProxy代理时，getServlet()方法返回null
