出错信息清楚的说明，“createuser”这个path应该以“/”字符开头

为定位这个错误，从以上错误信息，开始打开Struts的源码RequestProcessor.java进行研究，首先来到这一段：

public class RequestProcessor {。。。。。。protected boolean processValidate(HttpServletRequest request,HttpServletResponse response,ActionForm form,ActionMapping mapping)throws IOException, ServletException {if (form == null) {return (true);}// Was this request cancelled?if (request.getAttribute(Globals.CANCEL_KEY) != null) {if (log.isDebugEnabled()) {log.debug(" Cancelled transaction, skipping validation");}return (true);}// Has validation been turned off for this mapping?if (!mapping.getValidate()) {return (true);}// Call the form bean''s validation methodif (log.isDebugEnabled()) {log.debug(" Validating input form properties");}ActionMessages errors = form.validate(mapping, request);if ((errors == null) || errors.isEmpty()) {if (log.isTraceEnabled()) {log.trace(" No errors detected, accepting input");}return (true);}// Special handling for multipart requestif (form.getMultipartRequestHandler() != null) {if (log.isTraceEnabled()) {log.trace(" Rolling back multipart request");}form.getMultipartRequestHandler().rollback();}// Has an input form been specified for this mapping?String input = mapping.getInput();if (input == null) {if (log.isTraceEnabled()) {log.trace(" Validation failed but no input form available");}response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR,getInternal().getMessage("noInput",mapping.getPath()));return (false);}// Save our error messages and return to the input form if possibleif (log.isDebugEnabled()) {log.debug(" Validation failed, returning to ''" + input + "''");}request.setAttribute(Globals.ERROR_KEY, errors);if (moduleConfig.getControllerConfig().
