采用Claude Code和DeepSeek编写一个业务模块-171主机测评

导读：

相同的指令在DeepSeek免费网页版和Claude Code表现还是不一样。

Claude Code自动生成了源代码项目结构、核心功能、技术栈和使用说明。

DeepSeek使用的费用估计是1元左右。不是很贵。

❯ 采用Jakarta EE 10 编写销售用户的模块，有下面的主要要求：代码将运行在open liberty上，数据库采用IBM DB2 12.1。代码编写模式主要采用JSF+js/css > EJB> JPA/JDBC.

其中JSF不要使用第三方的库（比如 primefaces）

业务功能需求：模块包括一个销售用户列表界面，创建新的销售用户，删除销售用户，修改销售用户。销售用户的属性包括：用户名称（user name），密码，电子邮件，电话，Person

Type（是否为员工（Employee）），Business Unit。仅仅编写代码，不要打包、build、部署和测试

● 我已经为Open Liberty上的Jakarta EE 10创建了一个完整的销售用户管理模块。代码采用JSF + EJB + JPA架构，不使用任何第三方JSF库（如PrimeFaces）。

核心功能

1. 销售用户实体属性：

– 用户名称（user name）- 必填，唯一

– 密码（password）- 必填，SHA-256哈希存储

– 电子邮件（email）- 必填，邮箱格式验证

– 电话（phone）- 可选

– Person Type – 可选（Employee/Contractor/Partner）

– Business Unit – 可选

2. CRUD操作：

– 列表显示：使用h:dataTable展示所有用户

– 创建用户：表单验证、用户名唯一性检查、密码自动哈希

– 编辑用户：密码字段留空表示不修改，加载时清空密码字段

– 删除用户：带确认对话框

3. 安全特性：

– 密码使用SHA-256哈希存储

– 编辑时密码字段自动清空，防止哈希值泄露

– 用户名唯一性约束

4. 数据库配置：

– JPA持久化单元：SalesUserPU

– DB2 12.1方言配置

– JTA数据源：jdbc/salesUserDB

– 自动表生成策略（开发环境）

技术栈

– Jakarta EE 10：Jakarta Persistence 3.1、Jakarta Enterprise Beans 4.0、Jakarta Faces 4.0、Jakarta CDI 4.0

– 数据库：IBM DB2 12.1（通过JPA配置）

– 应用服务器：Open Liberty（示例配置）

– 前端：纯JSF标签（无第三方库）、CSS样式

– 构建工具：标准Maven目录结构（未提供pom.xml）

使用说明

1. 将代码部署到Open Liberty服务器

2. 配置DB2数据源（参考server.xml示例）

3. 访问/index.xhtml即可使用销售用户管理功能

代码已完整，包含所有必要的Java类、配置文件和Web资源，可直接用于开发环境。
