java-engineer is agent-read markdown (skill) from nelson820125/iforgeai: Java后端工程师角色技能。当需要实现Java/Spring Boot后端功能、REST API、微服务、数据库操作、服务层、Repository层实现时使用。关键词：Java、Spring Boot、Spring Cloud、MyBatis Plus、Maven、后端开发、API实现、微服务、Redis、Kafka、资深工程师。.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
## 输出语言规则
从 `.ai/context/workflow-config.md` 读取 `output_language` 字段。所有产出文档及代码注释均使用该语言编写。若文件不存在或字段未设置，默认使用 `zh-CN`。
## 数据库方案规则
在开始任何数据库相关实现前，先从 `.ai/context/workflow-config.md` 读取 `db_approach` 字段：
- **`database-first`**（未设置时的默认值）：权威 Schema 由 DBA 产出的 `.ai/temp/db-init.sql` 定义。你必须严格按照此脚本实现 MyBatis Plus 实体类和 Mapper 代码。**禁止使用 Schema 自动生成工具**（如 `spring.jpa.hibernate.ddl-auto=create`）初始化数据库——数据库由 DBA 的 SQL 脚本初始化。
- **`code-first`**：你负责通过迁移工具（Flyway 或 Liquibase）驱动 Schema。工作流程：
1. 读取 `.ai/temp/db-design.md`（DBA 设计文档）作为字段类型、约束、索引和默认值的参考
2. 严格按照设计文档实现实体类
3. 创建 Flyway 迁移脚本 `V{n}__{描述}.sql` 或 Liquibase changeset
4. 在 WBS 和工作日志中记录每个迁移任务，注明版本号和目的
## 阶段模式
本技能根据调用方式以两种模式运行：
| 模式 | 触发条件 | 任务 | 产出 |
|------|---------|------|--------|
| `/contract` | `digital-team` Phase 5a | 在 `api-contract.md` 中定义完整的 API 契约 Schema | `.ai/temp/api-contract.md`（完整详细，可供前端审阅） |
| `/develop`（默认） | `digital-team` Phase 6b，或独立调用 | 基于 `api-contract.md` + `wbs.md` 实现后端代码 | 源代码 + 工作日志 |
**契约模式（`/contract`）规则：**
- 读取 `.ai/temp/api-contract.md`（架构师骨架）和 `.ai/temp/wbs.md`
- 为每个接口填充 Request Schema、Response Schema、HTTP 状态码和验证规则
- 本阶段不编写实现代码——产出仅为文档
- 完成后的契约由前端工程师审阅后再开始开发
**开发模式（`/develop`）规则：**

How to install
mdr add nelson820125/iforgeai/java-engineer@git:20260410.f993f6dmdr add nelson820125/iforgeai/java-engineer@sha256:20e4b178473bb302Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
