# 新产品调查与分析第二步 Implementation Plan > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. **Goal:** 让学生完成新产品调查与分析的第二步，并在提交前由后端验证平台、场景、关键词、产品名和 1–5 张产品图片。 **Architecture:** 将 `new-product-survey.vue` 中旧的三行平台表格替换为单个调查表单，并将其 JSON 继续保存在现有 `StudentTrainingAnswer.step2Answer`。图片先沿用 `/common/upload` 上传，答案中只保存 `{ name, url }`；新增一个无状态的第二步校验服务与控制器入口，前端通过校验后才推进到第三步。 **Tech Stack:** Vue 3 Composition API、Element Plus、Vite、现有 RuoYi request 封装、Spring Boot、JUnit 5、Mockito。 ## Global Constraints - 仅调整学生端 `new-product-survey` 与对应学生答案接口；不改教师端、管理端或其余步骤。 - 案例资料按钮继续读取当前任务的 `materialUrl` 并下载，显示固定文案“下载案例资料”。 - `step2Answer` 必须兼容既有答案存储与本地草稿，不新建图片表。 - 第二步提交必须要求 1 至 5 张图片；选择“其他场景”时必须填写自定义场景。 - 演示模式只做本地校验与会话保存，不调用上传或新增后端校验接口。 --- ### Task 1: 后端第二步提交校验 **Files:** - Create: `E:/workspace/dianshang/link_commerce/.worktrees/new-product-survey-step1/src/main/java/com/sztzjy/linkCommerce/entity/dto/NewProductSurveyStepTwoValidationRequest.java` - Create: `E:/workspace/dianshang/link_commerce/.worktrees/new-product-survey-step1/src/main/java/com/sztzjy/linkCommerce/entity/dto/NewProductSurveyStepTwoValidationResult.java` - Create: `E:/workspace/dianshang/link_commerce/.worktrees/new-product-survey-step1/src/main/java/com/sztzjy/linkCommerce/service/NewProductSurveyStepTwoService.java` - Create: `E:/workspace/dianshang/link_commerce/.worktrees/new-product-survey-step1/src/main/java/com/sztzjy/linkCommerce/service/impl/NewProductSurveyStepTwoServiceImpl.java` - Modify: `E:/workspace/dianshang/link_commerce/.worktrees/new-product-survey-step1/src/main/java/com/sztzjy/linkCommerce/controller/stu/StudentTrainingAnswerController.java` - Test: `E:/workspace/dianshang/link_commerce/.worktrees/new-product-survey-step1/src/test/java/com/sztzjy/linkCommerce/service/impl/NewProductSurveyStepTwoServiceImplTest.java` - Test: `E:/workspace/dianshang/link_commerce/.worktrees/new-product-survey-step1/src/test/java/com/sztzjy/linkCommerce/controller/stu/StudentTrainingAnswerControllerTest.java` **Interfaces:** - Consumes: `JwtUser` and `POST /api/student-training-answers/new-product-survey/step-2/validate` request JSON. - Produces: `NewProductSurveyStepTwoService.validate(NewProductSurveyStepTwoValidationRequest, JwtUser)` returning `{ valid: true, message: "校验通过" }` or a 4xx `ServiceException`. - [ ] **Step 1: Write failing service tests** ```java @Test void validatesACompleteStudentSubmission() { NewProductSurveyStepTwoValidationResult result = service.validate(request("京东", "AI儿童玩具", "", twoImages()), student()); assertTrue(result.isValid()); } @Test void rejectsOtherSceneWithoutCustomSceneAndMoreThanFiveImages() { assertThrows(ServiceException.class, () -> service.validate(request("京东", "其他场景", "", oneImage()), student())); assertThrows(ServiceException.class, () -> service.validate(request("京东", "AI儿童玩具", "", sixImages()), student())); } ``` - [ ] **Step 2: Run the service test to verify it fails** Run: `mvn -B '-Dtest=NewProductSurveyStepTwoServiceImplTest' test` Expected: FAIL because the step-two DTO and service do not exist. - [ ] **Step 3: Implement the DTO, service, and validation rules** ```java public interface NewProductSurveyStepTwoService { NewProductSurveyStepTwoValidationResult validate(NewProductSurveyStepTwoValidationRequest request, JwtUser user); } // validate roleId == 4; platform in 京东/天猫/抖音电商; scene is nonblank; // customScene required only for 其他场景; keyword/productName nonblank; // imageUrls contains 1..5 nonblank URLs. Throw ServiceException(BAD_REQUEST, message) on failure. ``` - [ ] **Step 4: Expose the controller endpoint and its test** ```java @PostMapping("/new-product-survey/step-2/validate") public ResultEntity validateNewProductSurveyStepTwo( @RequestBody NewProductSurveyStepTwoValidationRequest answer, HttpServletRequest request) { return new ResultEntity<>(HttpStatus.OK, "校验通过", newProductSurveyStepTwoService.validate(answer, TokenProvider.getJWTUser(request))); } ``` Mock the new service in `StudentTrainingAnswerControllerTest` and assert the controller passes the request and JWT user through, returning HTTP 200. - [ ] **Step 5: Run focused backend tests** Run: `mvn -B '-Dtest=NewProductSurveyStepTwoServiceImplTest,StudentTrainingAnswerControllerTest' test` Expected: PASS with zero failures. - [ ] **Step 6: Commit the backend implementation** ```bash git add src/main/java src/test/java git commit -m "feat: validate new product survey step two" ``` ### Task 2: 前端第二步表单、上传与答案回填 **Files:** - Modify: `E:/workspace/dianshang/e-commerce-internet/.worktrees/new-product-survey-step1/src/api/studentTrainingAnswer.js` - Modify: `E:/workspace/dianshang/e-commerce-internet/.worktrees/new-product-survey-step1/src/views/foundation/new-product-survey.vue` - Modify: `E:/workspace/dianshang/e-commerce-internet/.worktrees/new-product-survey-step1/tests/new-product-survey-step-one.static.test.cjs` **Interfaces:** - Consumes: `uploadStudentTrainingFile(FormData)`, `checkNewProductSurveyStepTwo(form)` and the backend validation response. - Produces: `step2Answer` JSON `{ platform, scene, customScene, keyword, productName, images: Array<{name, url}> }` and only advances the wizard after validation succeeds. - [ ] **Step 1: Write failing frontend static assertions** ```js assert.match(source, /AI智能家居[\s\S]*AI美妆辅助[\s\S]*其他场景/); assert.match(source, /v-if="step2Form\.scene === '其他场景'"/); assert.match(source, /MAX_STEP_TWO_IMAGES = 5/); assert.match(source, /checkNewProductSurveyStepTwo/); assert.match(source, /step2Answer: JSON\.stringify\(step2Form\.value\)/); ``` - [ ] **Step 2: Run the static test to verify it fails** Run: `node tests/new-product-survey-step-one.static.test.cjs` Expected: FAIL because the page still renders `step2Rows` and has no step-two validation client. - [ ] **Step 3: Add the API client and local demo validator** ```js export function checkNewProductSurveyStepTwo(form) { if (isStudentDemo()) return Promise.resolve({ code: 200, data: validateStepTwoDemo(form) }); return request({ url: "/api/student-training-answers/new-product-survey/step-2/validate", method: "post", data: { ...form, imageUrls: form.images.map((image) => image.url) }, headers: { repeatSubmit: false }, }); } ``` `validateStepTwoDemo` must apply the same required-field, other-scene, and 1–5 image count rules and reject invalid data with an `Error`. - [ ] **Step 4: Replace the old table with the second-step form** ```vue {{ option.label }} ``` Use constants for the three platform options and six scene options. Implement `uploadStepTwoImages`, `removeStepTwoImage`, and `previewStepTwoImage`: reject non-images and selections that would exceed five files; upload files with `FormData`; store only name and resolved URL; show thumbnails in a dialog-capable preview. Replace all `step2Rows` watch, reset, draft, save, outcome, and restoration paths with `step2Form`, while retaining safe fallback behavior for old row-array answers. - [ ] **Step 5: Gate next-step navigation on step-two validation** ```js if (currentStep.value === 2) { await checkNewProductSurveyStepTwo(step2Form.value); await saveAnswer("IN_PROGRESS", true); advanceStep(); return; } ``` Show a human-readable validation/upload error and leave the user on step two on failure. Keep step-one grading and steps three/four navigation behavior unchanged. - [ ] **Step 6: Run frontend static test and production build** Run: `node tests/new-product-survey-step-one.static.test.cjs` Expected: PASS. Run: `node 'E:\workspace\dianshang\e-commerce-internet\node_modules\vite\bin\vite.js' build --config '.\vite.config.js'` Expected: build exits with code 0; retain only the repository’s pre-existing warnings. - [ ] **Step 7: Commit the frontend implementation** ```bash git add src/api/studentTrainingAnswer.js src/views/foundation/new-product-survey.vue tests/new-product-survey-step-one.static.test.cjs git commit -m "feat: collect new product survey step two" ``` ### Task 3: 全量验证与运行中的服务检查 **Files:** - Modify: no source files expected. **Interfaces:** - Consumes: committed frontend and backend worktree changes. - Produces: evidence that the new APIs compile and the updated student page is available on the already-started local services. - [ ] **Step 1: Run the complete backend suite** Run: `mvn -B test` Expected: all tests pass with zero failures. - [ ] **Step 2: Run all standalone frontend tests** Run: ```powershell $tests = Get-ChildItem tests -File | Where-Object { $_.Name -like '*.test.cjs' -or $_.Name -like '*.test.mjs' } foreach ($test in $tests) { node $test.FullName } ``` Expected: every test file exits 0. - [ ] **Step 3: Verify the running services** Run: `Invoke-WebRequest http://127.0.0.1:147/index.html -UseBasicParsing` and `Invoke-WebRequest http://127.0.0.1:7548/doc.html -UseBasicParsing`. Expected: both return HTTP 200. If the backend process predates the new commit, rebuild the backend JAR with `mvn -B package -DskipTests` and restart only the project JAR on port 7548. - [ ] **Step 4: Report verification and commits** Provide test/build outcomes, local URLs, and the two feature commit hashes. Do not merge the isolated worktree branches without an explicit user instruction.
