重新测试deepseek Jakarta EE 10编程能力-EW帮帮网

听说deepseek做了一个小更新，我重新测试了一下Jakarta EE 10编程能力；有点进步，遗漏的功能比以前少了。

采用Jakarta EE 10 编写员工信息表维护表，包括员工查询与搜索、员工列表、新增员工、删除员工，修改员工，要求用户界面主要采用JAVA SERVER FACE,如果用户界面采用JAVA SERVER FACE实现不了，增加JS完成实现不了的功能，业务逻辑采用EJB,数据库访问采用JPA. 员工信息表包含员工编号，姓名，部门，手机号码。

下面是一个完整的Jakarta EE 10员工信息管理系统实现方案，严格遵循您的要求：JSF作为主要UI框架、EJB处理业务逻辑、JPA进行数据访问，并在需要时使用JavaScript增强功能。

# 1. 创建数据库和数据源
$ sudo mysql -e "CREATE DATABASE employeedb"
$ sudo mysql -e "CREATE USER 'employee'@'localhost' IDENTIFIED BY 'password'"
$ sudo mysql -e "GRANT ALL ON employeedb.* TO 'employee'@'localhost'"

# 2. 配置WildFly数据源
$ /path/to/wildfly/bin/jboss-cli.sh
connect
module add --name=com.mysql --resources=/path/to/mysql-connector-j.jar --dependencies=javax.api,javax.transaction.api
data-source add --name=EmployeeDS --jndi-name=java:global/jdbc/EmployeeDS \
    --driver-name=mysql --connection-url=jdbc:mysql://localhost:3306/employeedb \
    --user-name=employee --password=password

# 3. 构建部署
mvn clean package wildfly:deploy

访问路径
- 员工列表：http://localhost:8080/yourapp/employee/list.xhtml
- 员工搜索：http://localhost:8080/yourapp/employee/search.xhtml
- 新增员工：http://localhost:8080/yourapp/employee/edit.xhtml

14. 技术选择原因

JSF作为主要UI框架
- 组件化开发模式
- 内置AJAX支持
- 强大的生命周期管理
- 与Jakarta EE无缝集成
JavaScript增强场景
- 客户端表单验证
