java - TestNG 测试给出 Null

Question

这是我想测试的方法

@PreAuthorize("isAuthenticated() and hasPermission(#request, 'CREATE_REQUISITION')")
    @RequestMapping(method = RequestMethod.POST, value = "/trade/createrequisition")
    public @ResponseBody
    void createRequisition(@RequestBody CreateRequisitionRO[] request,
            @RequestHeader("validateOnly") boolean validateOnly) {
        logger.debug("Starting createRequisition()...");
        for (int i = 0; i < request.length; i++) {
            CreateRequisitionRO requisitionRequest = request[i];

            // FIXME this has to be removed/moved
            requisitionRequest.setFundManager(requisitionRequest.getUserId());
            // FIXME might have to search using param level as well
            SystemDefault sysDefault = dbFuncs.references.systemDefault
                    .findByCompanyAndDivisionAndPortfolio(
                            userContext.getCompany(),
                            userContext.getDivision(),
                            requisitionRequest.getPortfolio());
            requisitionRequest.setCustodianN(sysDefault.getCustodianN());

            gateKeeper.route(requisitionRequest);
        }
    }

请纠正我，我不太明白我错在哪里。

看起来您没有初始化 webAPI 成员，因此此行会导致 NPE:

webAPI.createRequisition(request, true);
