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

@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

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

@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

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

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

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

<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

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

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:

$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.
