# PostgreSQL 配置
spring.datasource.url=jdbc:postgresql://your-postgresql-host:5432/your-database
spring.datasource.username=your-username
spring.datasource.password=your-password
spring.datasource.driver-class-name=org.postgresql.Driver
# Hibernate 配置
spring.jpa.hibernate.ddl-auto=none
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;
@Data
@TableName("user")
public class User {
    @TableId(value = "id", type = IdType.AUTO)
    private Long id;
    private String username;
    private String email;
    // 省略构造函数、getter 和 setter
}

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
public interface UserMapper extends BaseMapper<User> {
    // 可以添加一些自定义查询方法
}

@SpringBootApplication
@MapperScan("com.example.mapper")
public class YourApplication {
    public static void main(String[] args) {
        SpringApplication.run(YourApplication.class, args);
    }
}
