SpringBoot项目集成达梦数据库
本文将介绍如何在单个SpringBoot项目中配置和使用达梦数据库(DM Database)，采用简洁的单模块配置方式。
一、环境准备
- JDK版本：17
- SpringBoot版本：3.1.5
- 达梦数据库版本：DM8
- 开发工具：IntelliJ IDEA
二、项目依赖配置（pom.xml）

yaml
server:
port: 12300

spring:
datasource:

1.项目结构(简化可用)
bash

java
package com.example.damengdemo.entity;
import jakarta.persistence.*;
import org.hibernate.annotations.CreationTimestamp;
import org.hibernate.annotations.UpdateTimestamp;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
@Entity
@Table(name = "SYS_FOLDER")
public class SysFolder implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "folder_seq")
@SequenceGenerator(name = "folder_seq", sequenceName = "SEQ_SYS_FOLDER_ID", allocationSize = 1)
@Column(name = "ID", columnDefinition = "NUMBER(20) COMMENT '主键ID'")
public Long id;
@Column(name = "NAME", nullable = false, length = 100, columnDefinition = "VARCHAR2(100) COMMENT '文件夹名称'")
public String name;
@Column(name = "PARENT_ID", nullable = false, columnDefinition = "NUMBER(20) DEFAULT 0 COMMENT '父文件夹ID（0表示根目录）'")
public Long parentId = 0L;
@Column(name = "PATH", length = 1000, columnDefinition = "VARCHAR2(1000) COMMENT '完整路径（如/1/2/3）'")
public String path;
@Column(name = "ORDER_NUM", columnDefinition = "NUMBER(10) DEFAULT 0 COMMENT '排序号'")

public Integer delFlag = 0;
// 非数据库字段
@Transient
public List<SysFolder> children = new ArrayList<>();
@Transient
public String parentName;
}3.Repository接口示例（SysFolderRepository.java）
java
package com.example.damengdemo.repository;
import com.example.damengdemo.entity.SysFolder;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository
public interface SysFolderRepository extends JpaRepository<SysFolder, Long>, JpaSpecificationExecutor<SysFolder> {
/**
* 查询所有未删除的文件夹
*/
@Query("SELECT f FROM SysFolder f WHERE f.delFlag = 0")
List<SysFolder> findAllNotDeleted();
}4.测试Service（DamengTestService.java）
java
package com.example.damengdemo.service;
import com.example.damengdemo.entity.SysFolder;
import com.example.damengdemo.repository.SysFolderRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Service;
import java.util.Arrays;
import java.util.Date;
import java.util.List;
@Service
public class DamengTestService implements CommandLineRunner {
@Autowired
private SysFolderRepository sysFolderRepository;
@Override
public void run(String... args) throws Exception {
insert();
query();
}
public void insert() {
sysFolderRepository.saveAll(generateTestFolders());
}
public void query() {
System.out.println("数量为: " + sysFolderRepository.findAllNotDeleted().size());
}
public static List<SysFolder> generateTestFolders() {
// 模拟用户
String currentUser = "admin";
Date now = new Date();
// 生成根文件夹
SysFolder root = new SysFolder();
root.id = 1L;
root.name = "根目录";
root.parentId = 0L;
root.path = "/1";
root.createBy = currentUser;
root.updateBy = currentUser;
root.createTime = now;
root.updateTime = now;
// 生成一级文件夹
SysFolder docFolder = createFolder(2L, "文档", 1L, "/1/2", 1, currentUser, now);
SysFolder imageFolder = createFolder(3L, "图片", 1L, "/1/3", 2, currentUser, now);
SysFolder videoFolder = createFolder(4L, "视频", 1L, "/1/4", 3, currentUser, now);
// 生成二级文件夹
SysFolder workDoc = createFolder(5L, "工作文档", 2L, "/1/2/5", 1, currentUser, now);
SysFolder personalDoc = createFolder(6L, "个人文档", 2L, "/1/2/6", 2, currentUser, now);
SysFolder vacationImage = createFolder(7L, "假期照片", 3L, "/1/3/7", 1, currentUser, now);
SysFolder tutorialVideo = createFolder(8L, "教程视频", 4L, "/1/4/8", 1, currentUser, now);
// 生成三级文件夹
SysFolder projectA = createFolder(9L, "项目A文档", 5L, "/1/2/5/9", 1, currentUser, now);
SysFolder projectB = createFolder(10L, "项目B文档", 5L, "/1/2/5/10", 2, currentUser, now);
// 构建文件夹层级关系
workDoc.children = Arrays.asList(projectA, projectB);
docFolder.children = Arrays.asList(workDoc, personalDoc);
imageFolder.children = Arrays.asList(vacationImage);
videoFolder.children = Arrays.asList(tutorialVideo);
root.children = Arrays.asList(docFolder, imageFolder, videoFolder);
return Arrays.asList(
root, docFolder, imageFolder, videoFolder,
workDoc, personalDoc, vacationImage,
tutorialVideo, projectA, projectB
);
}
private static SysFolder createFolder(Long id, String name, Long parentId,
String path, int orderNum,
String user, Date time) {
SysFolder folder = new SysFolder();
folder.id = id;
folder.name = name;
folder.parentId = parentId;
folder.path = path;
folder.orderNum = orderNum;
folder.createBy = user;
folder.updateBy = user;
folder.createTime = time;
folder.updateTime = time;
return folder;
}
}5.启动类（DamengDemoApplication.java）
java
package com.example.damengdemo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.ApplicationContext;
@SpringBootApplication
public class DamengDemoApplication extends SpringBootServletInitializer {
private static ApplicationContext context;
public static void main(String[] args) {
SpringApplication springApplication = new SpringApplication(DamengDemoApplication.class);
context = springApplication.run(args);
}
public static void start(String[] args) {
main(args);
}
public static void stop(String[] args) {
System.exit(SpringApplication.exit(context));
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(DamengDemoApplication.class);
}
}五、总结
