Spring Boot：Boot2.0版本整合Neo4j

前面介绍了Boot 1.5版本集成Neo4j，Boot 2.0以上版本Neo4j变化较大。
场景还是电影人员关系

Boot 2.0主要变化

1. GraphRepository在Boot2.0下不支持了，调整为Neo4jRepository。
   对应的findById和deleteById也要调整。
2. @GraphId也不支持需要改成@Id @GeneratedValue 。
3. 链接方式调整为bolt://192.168.1.8:7687

Demo

1. pom文件
   调整boot的版本

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.0.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

2. application.yml配置

spring:
  data:
    neo4j:
      uri: bolt://192.168.1.8:7687
      username: neo4j
      password: 123456

3. 模型类调整为
   Person类

package com.github.davidji80.springboot.neo4j.model;
import org.neo4j.ogm.annotation.*;
@NodeEntity(label = "Person")

public class Person {

@Id

@GeneratedValue

private Long nodeId;
@Property(name = "name")

private String name;
@Property(name = "born")

private int born;
public Long getNodeId() {

return nodeId;

}
public void setNodeId(Long nodeId) {

this.nodeId = nodeId;

}
public String getName() {

return name;

}
public void setName(String name) {

this.name = name;

}
public int getBorn() {

return born;

}
public void setBorn(int born) {

this.born = born;

}

}

4. DAO调整为
   PersonRepository

package com.github.davidji80.springboot.neo4j.dao;
import com.github.davidji80.springboot.neo4j.model.Person;

import org.springframework.data.neo4j.repository.Neo4jRepository;
public interface PersonRepository extends Neo4jRepository<Person, Long> {

}

5. Service层调整

package com.github.davidji80.springboot.neo4j.service.impl;
import com.github.davidji80.springboot.neo4j.dao.ActedInRepository;

import com.github.davidji80.springboot.neo4j.dao.DirectedRepository;

import com.github.davidji80.springboot.neo4j.dao.MovieRepository;

import com.github.davidji80.springboot.neo4j.dao.PersonRepository;

import com.github.davidji80.springboot.neo4j.model.ActedIn;

import com.github.davidji80.springboot.neo4j.model.Directed;

import com.github.davidji80.springboot.neo4j.model.Movie;

import com.github.davidji80.springboot.neo4j.model.Person;

import com.github.davidji80.springboot.neo4j.service.MovieServer;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;
import java.util.Optional;
@Service

public class MovieServiceImpl implements MovieServer {
@Autowired

private PersonRepository personRepository;

@Autowired

private MovieRepository movieRepository;

@Autowired

private DirectedRepository directedRepository;

@Autowired

private ActedInRepository actedInRepository;
@Override

public Person addPerson(Person person){

return personRepository.save(person);

}

@Override

public Person findOnePerson(long id){

return personRepository.findById(id).get();

}

@Override

public void deleteOnePerson(long id){

personRepository.deleteById(id);

}

@Override

public Movie addMovie(Movie movie){

return movieRepository.save(movie);

}

@Override

public Movie findOneMovie(long id){

return movieRepository.findById(id).get();

}

@Override

public Directed directed(Directed directed){

return directedRepository.save(directed);

}

@Override

public ActedIn actedIn(ActedIn actedIn) {

return actedInRepository.save(actedIn);

}

}
