+# 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<NewProductSurveyStepTwoValidationResult> 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
+<el-radio-group v-model="step2Form.platform">
+  <el-radio v-for="option in PLATFORM_OPTIONS" :key="option.value" :label="option.value">{{ option.label }}</el-radio>
+</el-radio-group>
+<input v-if="step2Form.scene === '其他场景'" v-model.trim="step2Form.customScene" />
+<input type="file" accept="image/*" multiple @change="uploadStepTwoImages" />
+```
+
+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.
