7. 主应用类 (SmartElderlyCareApplication.java)

package com.example.smartelderlycare;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SmartElderlyCareApplication {
    public static void main(String[] args) {
        SpringApplication.run(SmartElderlyCareApplication.class, args);
    }
}

8. 配置文件 (application.properties)

spring.datasource.url=jdbc:h2:mem:elderlycare
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=password
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.h2.console.enabled=true

9. 运行项目

1. 使用 mvn spring-boot:run 命令运行项目。
2. 访问 http://localhost:8080/h2-console 查看H2数据库。
3. 使用API工具（如Postman）测试各个接口。

10. 扩展功能

• 添加用户登录和权限管理（使用Spring Security）。
• 添加健康数据分析功能，根据健康记录生成报告。
