一、环境准备

JDK 17+
Maven 3.8+
Spring Boot 3.2+
ArangoDB 3.11+（本地安装或Docker运行）

Docker启动ArangoDB

docker run -d --name arangodb \-p 8529:8529 \-e ARANGO_ROOT_PASSWORD=rootpassword \arangodb:latest

二、创建Spring Boot项目

使用start.spring.io创建项目
添加依赖：
- Spring Web
- Lombok

三、添加ArangoDB依赖

<!-- pom.xml -->
<dependency><groupId>com.arangodb</groupId><artifactId>arangodb-spring-data</artifactId><version>3.8.0</version>
</dependency>

四、配置ArangoDB连接

# application.yml
arangodb:host: 127.0.0.1port: 8529user: rootpassword: rootpassworddatabase: spring_db

创建配置类：

@Configuration
@EnableArangoRepositories(basePackages = "com.example.repository")
public class ArangoConfig {@Value("${arangodb.host}")private String host;@Value("${arangodb.port}")private int port;@Value("${arangodb.user}")private String user;@Value("${arangodb.password}")private String password;@Value("${arangodb.database}")private String database;@Beanpublic ArangoDB.Builder arangoBuilder() {return new ArangoDB.Builder().host(host, port).user(user).password(password);}@Beanpublic ArangoDatabase arangoDatabase() {return arangoBuilder().build().db(database);}
}

五、创建实体类

@Document("users")
@Data
@NoArgsConstructor
@AllArgsConstructor
public class User {@Idprivate String id;@ArangoIdprivate String arangoId;private String name;private String email;private Integer age;
}

六、创建Repository接口

public interface UserRepository extends ArangoRepository<User, String> {// 自定义查询方法@Query("FOR u IN users FILTER u.age >= @0 RETURN u")List<User> findByAgeGreaterThanEqual(int age);
}

七、实现Service层

@Service
@RequiredArgsConstructor
public class UserService {private final UserRepository userRepository;public User createUser(User user) {return userRepository.save(user);}public List<User> getAllUsers() {return (List<User>) userRepository.findAll();}public List<User> getUsersByAge(int age) {return userRepository.findByAgeGreaterThanEqual(age);}
}

八、创建REST控制器

@RestController
@RequestMapping("/api/users")
@RequiredArgsConstructor
public class UserController {private final UserService userService;@PostMappingpublic ResponseEntity<User> createUser(@RequestBody User user) {return ResponseEntity.ok(userService.createUser(user));}@GetMappingpublic ResponseEntity<List<User>> getAllUsers() {return ResponseEntity.ok(userService.getAllUsers());}@GetMapping("/age/{age}")public ResponseEntity<List<User>> getUsersByAge(@PathVariable int age) {return ResponseEntity.ok(userService.getUsersByAge(age));}
}

九、测试验证

启动Spring Boot应用
使用Postman测试：
- POST /api/users
```
{"name": "John Doe","email": "john@example.com","age": 28
}
```
- GET /api/users 查看所有用户
- GET /api/users/age/25 查询年龄≥25的用户

十、高级查询示例

// 在Repository中添加
@Query("FOR u IN users FILTER u.name == @name RETURN u")
List<User> findByName(@Param("name") String name);// 复杂查询示例
@Query("FOR u IN users FILTER u.age >= @minAge AND u.age <= @maxAge RETURN u")
List<User> findByAgeRange(@Param("minAge") int minAge, @Param("maxAge") int maxAge);

十一、事务管理

@Autowired
private ArangoDatabase arangoDatabase;public void transactionalOperation() {arangoDatabase.transaction("users", Collections.emptyMap(),trx -> {User user1 = new User("Alice", "alice@example.com", 30);User user2 = new User("Bob", "bob@example.com", 25);trx.collection("users").insertDocument(user1);trx.collection("users").insertDocument(user2);return null;},Void.class);
}
