!-- 1. 继承Spring Boot Starter Parent --!-- 这是Spring Boot Maven项目的标准方式它提供了默认的依赖管理和插件配置 --parentgroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-parent/artifactIdversion2.2.2.RELEASE/versionrelativePath/ !-- 从仓库查找父pom不本地查找 --/parent!-- 这些依赖的版本由spring-boot-starter-parent统一管理通常无需显式指定版本 --dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-data-neo4j/artifactId/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId/dependency2、yml配置
datasource:host: localhostport: 7687username: neo4jpassword: 123456management:endpoint:health:show-details: alwayslogging:level:org.neo4j.ogm.drivers.bolt.request: DEBUGorg.springframework.data.neo4j: DEBUG3、代码核心配置import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.neo4j.repository.config.EnableNeo4jRepositories;EnableNeo4jRepositories(ru.vladigeras.springneo4j.repository)
EntityScan(basePackages ru.vladigeras.springneo4j.model)
Configuration
public class Neo4jConfiguration {Value(${datasource.host})private String host;Value(${datasource.port})private String port;Value(${datasource.username})private String username;Value(${datasource.password})private String password;Beanpublic org.neo4j.ogm.config.Configuration configuration() {return new org.neo4j.ogm.config.Configuration.Builder().uri(bolt:// host : port).credentials(username, password).build();}
}
4、查询接口配置和实现
Repository
public interface LineRepository extends Neo4jRepositoryLineNode, Long {
}#业务接口
ListLineNode getLines();#实现
Transactional(readOnly true)Overridepublic ListLineNode getLines() {ListLineNode result new ArrayList();IteratorLineNode iterator lineRepository.findAll().iterator();iterator.forEachRemaining(result::add);return result;}#控制侧ApiOperation(GetLines)GetMapping(/lines)ResponseStatus(HttpStatus.OK)public ListLine getLines() {return stationService.getLines().stream().map(StationMapper::of).collect(Collectors.toList());}#实体import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;ApiModel(description Line info)
public class Line {ApiModelProperty(identifier)private Long id;ApiModelProperty(line name)private String name;public Long getId() {return id;}public Line setId(Long id) {this.id id;return this;}public String getName() {return name;}public Line setName(String name) {this.name name;return this;}
}
5新增接口配置实现
#控制层 ApiOperation(CreateLine)PostMapping(/lines)ResponseStatus(HttpStatus.CREATED)public void add(ApiParam(Line info)RequestBody NewLine line) {stationService.save(line);}#voimport io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;ApiModel(description Line info)
public class NewLine {ApiModelProperty(line name)private String name;public String getName() {return name;}public NewLine setName(String name) {this.name name;return this;}
}#接口
void save(NewLine line);#接口实现TransactionalOverridepublic void save(NewLine line) {LineNode lineNode new LineNode();lineNode.setName(line.getName());lineRepository.save(lineNode);}6、启动类import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;SpringBootApplication
public class SpringNeo4jApplication {public static void main(String[] args) {SpringApplication.run(SpringNeo4jApplication.class, args);}}
启动成功就可以演示了。
