产品开发关键因素第 3 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: 为学生端产品开发关键因素实训实现第 3 步商业化及市场反馈分析、服务端校验与只保存进入第 4 步的流程。

Architecture: 前端在现有 product-development-factors.vue 中增加固定三行的第 3 步表格，并把数据独立写入 step3Answer。后端按前两步的分层模式新增 DTO、服务及控制器入口，严格验证学生身份、三项固定维度及六个非空分析字段。

Tech Stack: Vue 3 Composition API、Element Plus、现有 request API；Spring Boot、JUnit 5、Mockito、Maven。

Global Constraints

• 仅修改学生端页面及学生答案校验接口；不调整教师端或任务配置。
• 不新增数据库表或字段，使用既有答案记录的 step3Answer 与 currentStep。
• 第 3 步保存固定使用 SAVE、submitted: false、currentStep: 4，不得提交任务。
• 保存前必须通过正式或演示模式的一致校验：三个固定维度、六个分析字段全部非空。

Task 1: 第 3 步后端校验服务

Files:

• Create: src/main/java/com/sztzjy/linkCommerce/entity/dto/ProductDevelopmentFactorsStepThreeValidationRequest.java
• Create: src/main/java/com/sztzjy/linkCommerce/entity/dto/ProductDevelopmentFactorsStepThreeValidationResult.java
• Create: src/main/java/com/sztzjy/linkCommerce/service/ProductDevelopmentFactorsStepThreeService.java
• Create: src/main/java/com/sztzjy/linkCommerce/service/impl/ProductDevelopmentFactorsStepThreeServiceImpl.java
• Test: src/test/java/com/sztzjy/linkCommerce/service/impl/ProductDevelopmentFactorsStepThreeServiceImplTest.java

Interfaces:

• Consumes: JwtUser、ServiceException、Spring HTTP status conventions。

• Produces: ProductDevelopmentFactorsStepThreeService#validate(ProductDevelopmentFactorsStepThreeValidationRequest, JwtUser)，返回 { valid, message }。

• Step 1: 写失败服务测试

@Test void acceptsCompleteStudentAnalyses() {
    assertTrue(new ProductDevelopmentFactorsStepThreeServiceImpl().validate(valid(), student()).isValid());
}

@Test void rejectsBlankOrForgedAnalyses() {
    ProductDevelopmentFactorsStepThreeValidationRequest blank = valid();
    blank.getFactors().get(2).setFailedAnalysis(" ");
    assertThrows(ServiceException.class, () -> service.validate(blank, student()));
    ProductDevelopmentFactorsStepThreeValidationRequest forged = valid();
    forged.getFactors().get(2).setDimension("伪造维度");
    assertThrows(ServiceException.class, () -> service.validate(forged, student()));
}

• Step 2: 运行测试确认失败

Run: mvn -B -Dtest=ProductDevelopmentFactorsStepThreeServiceImplTest test

Expected: FAIL，因为 DTO 和服务尚不存在。

• Step 3: 实现最小服务

private static final Set<String> DIMENSIONS = new LinkedHashSet<>(Arrays.asList(
    "供应链与成本控制", "商业模式", "市场反馈"));

if (user == null || StringUtils.isBlank(user.getUserId())) throw new ServiceException(HttpStatus.UNAUTHORIZED, "请先登录后再提交");
if (user.getRoleId() != 4) throw new ServiceException(HttpStatus.FORBIDDEN, "仅学生可提交实训答案");

校验 factors 数量为 3、每个维度只出现一次且属于 DIMENSIONS，并要求每个 successAnalysis、failedAnalysis 均非空；合法时返回 valid=true、message="校验通过"。

• Step 4: 运行服务测试确认通过

Run: mvn -B -Dtest=ProductDevelopmentFactorsStepThreeServiceImplTest test

Expected: PASS，覆盖合法、空值、伪造维度和非学生身份。

• Step 5: 提交后端服务

git add src/main/java/com/sztzjy/linkCommerce/entity/dto/ProductDevelopmentFactorsStepThreeValidationRequest.java src/main/java/com/sztzjy/linkCommerce/entity/dto/ProductDevelopmentFactorsStepThreeValidationResult.java src/main/java/com/sztzjy/linkCommerce/service/ProductDevelopmentFactorsStepThreeService.java src/main/java/com/sztzjy/linkCommerce/service/impl/ProductDevelopmentFactorsStepThreeServiceImpl.java src/test/java/com/sztzjy/linkCommerce/service/impl/ProductDevelopmentFactorsStepThreeServiceImplTest.java
git commit -m "feat: validate product factors step three"

Task 2: 第 3 步校验控制器入口

Files:

• Modify: src/main/java/com/sztzjy/linkCommerce/controller/stu/StudentTrainingAnswerController.java
• Modify: src/test/java/com/sztzjy/linkCommerce/controller/stu/StudentTrainingAnswerControllerTest.java

Interfaces:

• Consumes: Task 1 的 ProductDevelopmentFactorsStepThreeService。

• Produces: POST /api/student-training-answers/product-development-factors/step-3/validate。

• Step 1: 写失败控制器测试

@Test void validateProductDevelopmentFactorsStepThreeUsesTheAuthenticatedStudentAndReturnsTheValidationResult() {
    ProductDevelopmentFactorsStepThreeService service = mock(ProductDevelopmentFactorsStepThreeService.class);
    ReflectionTestUtils.setField(controller, "productDevelopmentFactorsStepThreeService", service);
    when(service.validate(any(ProductDevelopmentFactorsStepThreeValidationRequest.class), any(JwtUser.class))).thenReturn(validation);
    ResultEntity<ProductDevelopmentFactorsStepThreeValidationResult> result = controller.validateProductDevelopmentFactorsStepThree(new ProductDevelopmentFactorsStepThreeValidationRequest(), authenticatedStudentRequest());
    assertEquals(HttpStatus.OK, result.getStatusCode());
}

• Step 2: 运行测试确认失败

Run: mvn -B -Dtest=StudentTrainingAnswerControllerTest test

Expected: FAIL，因为第 3 步服务注入字段和控制器方法尚不存在。

• Step 3: 增加路由与转发

@PostMapping("/product-development-factors/step-3/validate")
public ResultEntity<ProductDevelopmentFactorsStepThreeValidationResult> validateProductDevelopmentFactorsStepThree(
        @RequestBody ProductDevelopmentFactorsStepThreeValidationRequest request,
        HttpServletRequest servletRequest) {
    return ResultEntity.ok(productDevelopmentFactorsStepThreeService.validate(request, getJwtUser(servletRequest)));
}

• Step 4: 运行控制器测试确认通过

Run: mvn -B -Dtest=StudentTrainingAnswerControllerTest,ProductDevelopmentFactorsStepThreeServiceImplTest test

Expected: PASS。

• Step 5: 提交控制器

git add src/main/java/com/sztzjy/linkCommerce/controller/stu/StudentTrainingAnswerController.java src/test/java/com/sztzjy/linkCommerce/controller/stu/StudentTrainingAnswerControllerTest.java
git commit -m "feat: expose product factors step three validation"

Task 3: 第 3 步学生页面、草稿和 API

Files:

• Modify: src/views/foundation/product-development-factors.vue
• Modify: src/api/studentTrainingAnswer.js
• Modify: tests/product-development-factors-step-one.static.test.cjs

Interfaces:

• Consumes: Task 2 的正式校验 URL、既有 saveStudentTrainingAnswer、getStudentTrainingAnswer。

• Produces: 第 3 步固定三行分析页面；step3Answer、currentStep: 4、checkProductDevelopmentFactorsStepThree(payload)。

• Step 1: 先扩展前端静态契约测试

assert.match(pageSource, /STEP_THREE_FACTOR_ROWS/);
assert.match(pageSource, /供应链与成本控制/);
assert.match(pageSource, /商业模式/);
assert.match(pageSource, /市场反馈/);
assert.match(pageSource, /step3Answer/);
assert.match(pageSource, /saveAndGoToStepFour/);
assert.match(apiSource, /product-development-factors\/step-3\/validate/);

• Step 2: 运行静态测试确认失败

Run: node tests/product-development-factors-step-one.static.test.cjs

Expected: FAIL，因为第 3 步常量、保存函数和 API 尚不存在。

• Step 3: 实现前端最小改动

在 currentStep === 2 增加表格；建立 STEP_THREE_FACTOR_ROWS、createStepThreeRows、stepThreeRows，并扩展草稿、答案恢复、导出与清空。

function buildStepThreeAnswerPayload(saveAction = "SAVE", persistedStep = 4) {
  return {
    step3Answer: JSON.stringify(buildStepThreeOutcome()),
    currentStep: persistedStep,
    submitted: false,
    saveAction,
  };
}

实现正式 API 和演示模式的一致校验；saveAndGoToStepFour 成功后清理草稿并在第 4 步存在时将 currentStep 设为 3，否则显示已保存但未配置第 4 步的提示。

• Step 4: 运行前端测试与生产构建

Run: node tests/product-development-factors-step-one.static.test.cjs; npm run build:prod

Expected: 静态契约测试与生产构建均 PASS。

• Step 5: 提交前端改动

git add src/views/foundation/product-development-factors.vue src/api/studentTrainingAnswer.js tests/product-development-factors-step-one.static.test.cjs
git commit -m "feat: add product factors step three analysis"

Task 4: 全量回归与交付检查

Files:

• Verify only: 前后端工作树的已提交变更。

Interfaces:

• Consumes: Tasks 1–3。

• Produces: 经过完整回归验证的前后端功能分支。

• Step 1: 运行后端全量测试

Run: mvn -B test

Expected: BUILD SUCCESS，所有测试通过。

• Step 2: 运行前端完整验证

Run: node tests/product-development-factors-step-one.static.test.cjs; npm run build:prod

Expected: 静态契约测试和生产构建成功。

• Step 3: 审查工作树

Run: git status --short; git log --oneline -3

Expected: 仅本功能的预期提交；不纳入主工作区已有未跟踪文件。

• Step 4: 汇报并等待集成指令

报告功能、提交和验证结果，等待用户明确指示合并、推送或发布。
