# 创建项目功能 - 后端实施计划

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**目标:** 实现创建项目功能的后端接口，包括数据库表、实体类、DTO/VO、Mapper、Service、Controller

**架构:** 基于若依框架 + MyBatis Plus，采用分层架构（Controller -> Service -> Mapper）

**技术栈:** Spring Boot 3.5.8, MyBatis Plus 3.5.10, MySQL 8.2.0, SpringDoc OpenAPI 2.8.14

---

## 前置条件

- MySQL 数据库已启动
- 后端项目已启动
- 已有 admin 账号和测试权限
- 数据库连接配置正确

---

## Task 1: 创建数据库表和字典数据

**文件:**
- Create: `sql/ccdi_project.sql`

**Step 1: 创建 SQL 脚本文件**

创建文件 `sql/ccdi_project.sql`，内容如下：

```sql
-- 创建项目表
CREATE TABLE `ccdi_project` (
  `project_id` BIGINT NOT NULL AUTO_INCREMENT COMMENT '项目ID',
  `project_name` VARCHAR(100) NOT NULL COMMENT '项目名称',
  `project_desc` VARCHAR(500) DEFAULT NULL COMMENT '项目描述',
  `config_type` VARCHAR(20) NOT NULL DEFAULT 'default' COMMENT '配置方式：default-全局默认，custom-自定义',
  `project_status` CHAR(1) NOT NULL DEFAULT '0' COMMENT '项目状态：0-进行中，1-已完成，2-已归档',
  `target_count` INT NOT NULL DEFAULT 0 COMMENT '目标人数',
  `high_risk_count` INT NOT NULL DEFAULT 0 COMMENT '高风险人数',
  `medium_risk_count` INT NOT NULL DEFAULT 0 COMMENT '中风险人数',
  `low_risk_count` INT NOT NULL DEFAULT 0 COMMENT '低风险人数',
  `create_by` VARCHAR(64) DEFAULT '' COMMENT '创建者',
  `create_time` DATETIME DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `update_by` VARCHAR(64) DEFAULT '' COMMENT '更新者',
  `update_time` DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  `remark` VARCHAR(500) DEFAULT NULL COMMENT '备注',
  PRIMARY KEY (`project_id`),
  INDEX `idx_project_name` (`project_name`),
  INDEX `idx_project_status` (`project_status`),
  INDEX `idx_create_time` (`create_time`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='纪检初核项目表';

-- 插入项目状态字典
INSERT INTO sys_dict_type (dict_name, dict_type, status, create_by, create_time, remark)
VALUES ('项目状态', 'ccdi_project_status', '0', 'admin', NOW(), '纪检初核项目状态');

INSERT INTO sys_dict_data (dict_sort, dict_label, dict_value, dict_type, css_class, list_class, is_default, status, create_by, create_time)
VALUES
(1, '进行中', '0', 'ccdi_project_status', '', 'primary', 'Y', '0', 'admin', NOW()),
(2, '已完成', '1', 'ccdi_project_status', '', 'success', 'N', '0', 'admin', NOW()),
(3, '已归档', '2', 'ccdi_project_status', '', 'info', 'N', '0', 'admin', NOW());

-- 插入配置方式字典
INSERT INTO sys_dict_type (dict_name, dict_type, status, create_by, create_time, remark)
VALUES ('配置方式', 'ccdi_config_type', '0', 'admin', NOW(), '项目配置方式');

INSERT INTO sys_dict_data (dict_sort, dict_label, dict_value, dict_type, css_class, list_class, is_default, status, create_by, create_time)
VALUES
(1, '全局默认模型参数配置', 'default', 'ccdi_config_type', '', 'primary', 'Y', '0', 'admin', NOW()),
(2, '自定义项目规则参数配置', 'custom', 'ccdi_config_type', '', 'warning', 'N', '0', 'admin', NOW());

-- 插入菜单权限
INSERT INTO sys_menu (menu_name, parent_id, order_num, path, component, menu_type, visible, status, perms, icon, create_by, create_time)
VALUES ('纪检初核管理', 0, 1, 'ccdi', NULL, 'M', '0', '0', '', 'monitor', 'admin', NOW());

SET @parent_id = LAST_INSERT_ID();

INSERT INTO sys_menu (menu_name, parent_id, order_num, path, component, menu_type, visible, status, perms, icon, create_by, create_time)
VALUES ('项目管理', @parent_id, 1, 'project', 'ccdiProject/index', 'C', '0', '0', 'ccdi:project:list', 'project', 'admin', NOW());

SET @menu_id = LAST_INSERT_ID();

INSERT INTO sys_menu (menu_name, parent_id, order_num, menu_type, visible, status, perms, create_by, create_time)
VALUES
('创建项目', @menu_id, 1, 'F', '0', '0', 'ccdi:project:add', 'admin', NOW()),
('编辑项目', @menu_id, 2, 'F', '0', '0', 'ccdi:project:edit', 'admin', NOW()),
('删除项目', @menu_id, 3, 'F', '0', '0', 'ccdi:project:remove', 'admin', NOW()),
('查询项目', @menu_id, 4, 'F', '0', '0', 'ccdi:project:query', 'admin', NOW());

-- 为管理员角色分配权限
INSERT INTO sys_role_menu (role_id, menu_id)
SELECT 1, menu_id FROM sys_menu WHERE perms LIKE 'ccdi:project:%' OR perms = 'ccdi:project:list';
```

**Step 2: 执行 SQL 脚本**

运行命令连接数据库并执行脚本：

```bash
mysql -h<host> -u<user> -p<password> ccdi < sql/ccdi_project.sql
```

预期输出：无错误，表创建成功

**Step 3: 验证数据库表**

连接数据库验证表是否创建成功：

```bash
mysql -h<host> -u<user> -p<password> -e "USE ccdi; SHOW TABLES LIKE 'ccdi_project'; DESC ccdi_project;"
```

预期输出：显示 `ccdi_project` 表及其字段结构

**Step 4: 验证字典数据**

验证字典数据是否插入成功：

```bash
mysql -h<host> -u<user> -p<password> -e "USE ccdi; SELECT * FROM sys_dict_type WHERE dict_type IN ('ccdi_project_status', 'ccdi_config_type'); SELECT * FROM sys_dict_data WHERE dict_type IN ('ccdi_project_status', 'ccdi_config_type');"
```

预期输出：显示新插入的字典类型和数据

**Step 5: 提交代码**

```bash
git add sql/ccdi_project.sql
git commit -m "feat: 添加项目表和字典数据SQL脚本"
```

    @Operation(summary = "查询项目详情")
    @PreAuthorize("@ss.hasPermi('ccdi:project:query')")
    public AjaxResult getProject(@PathVariable Long projectId) {
        CcdiProjectVO vo = projectService.getProjectById(projectId);
        return AjaxResult.success(vo);

    /**

        Page<CcdiProjectVO> page = new Page<>(pageDomain.getPageNum(), pageDomain.getPageSize());
        Page<CcdiProjectVO> result = projectService.selectProjectPage(page, queryDTO);

}
```

**Step 2: 验证编译**

```bash
cd ruoyi-info-collection && mvn clean compile
```

预期输出：BUILD SUCCESS

**Step 3: 提交代码**

```bash
git add ruoyi-info-collection/src/main/java/com/ruoyi/info/collection/controller/CcdiProjectController.java
git commit -m "feat: 添加项目Controller"
```

## Task 11: 启动后端并测试接口

**Step 1: 启动后端服务**

```bash
cd ruoyi-admin && mvn spring-boot:run
```

预期输出：Spring Boot 启动成功日志，端口 8080

**Step 2: 获取测试 Token**

使用测试接口获取 Token：

```bash
curl -X POST "http://localhost:8080/login/test?username=admin&password=admin123"
```

预期输出：返回包含 token 的 JSON 响应

**Step 3: 测试创建项目接口**

使用 Token 测试创建项目接口：

```bash
curl -X POST "http://localhost:8080/ccdi/project" \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "projectName": "测试项目1",
    "projectDesc": "这是测试项目描述",
    "configType": "default"
  }'
```

预期输出：返回成功响应，包含项目 ID 和创建的项目信息

**Step 4: 测试查询项目列表接口**

```bash
curl -X GET "http://localhost:8080/ccdi/project/list?pageNum=1&pageSize=10" \
  -H "Authorization: Bearer <token>"
```

预期输出：返回分页数据，包含刚才创建的项目

**Step 5: 使用 Swagger 测试**

访问 Swagger UI 进行接口测试：

```bash
# 浏览器打开
http://localhost:8080/swagger-ui/index.html
```

预期结果：在 Swagger UI 中可以看到项目管理的所有接口，并进行测试

---

## Task 12: 提交最终代码

**Step 1: 检查所有文件**

```bash
git status
```

预期输出：所有后端文件已提交

**Step 2: 推送到远程仓库**

```bash
git push origin dev
```

预期输出：推送成功
