如何消除Spring Neo4j启动时的警告？

我正在使用Springboot配合Spring Data Neo4j进行开发，应用程序可以正常运行。

但是，启动时会出现一大堆警告信息，如果有可能的话，我希望能够去除这些警告。

什么导致它如此不开心？
你最终解决了这个问题吗？ - SledgeHammer
不好意思，我目前只是在过滤它们 :( - GreenAsJade
实际上，我最终解决了它... :)。我会发布一个答案... - SledgeHammer

我遇到了同样的问题，经过两天的摸索，终于找到了解决方法...

我的 pom.xml 文件如下：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-neo4j</artifactId>
        <version>2.2.2.RELEASE</version> <!--$NO-MVN-MAN-VER$-->
    </dependency>

通常情况下，您的应用程序属性中会包含用户名和密码：
spring.data.neo4j.open-in-view=false
spring.data.neo4j.uri=bolt://localhost
spring.data.neo4j.username=neo4j
spring.data.neo4j.password=xxx

你还需要使用以下方法:

@EnableNeo4jRepositories

Neo4j代码似乎默认扫描你的应用程序中的所有类，但你可以覆盖此行为：

  1. 创建一个配置类并将@EnableNeo4jRepositories移动到其中。
  2. 指定你的仓库基础包.
  3. 指定你的模型基础包.

现在，Neo4j代码知道只扫描repo和model包。 这是我针对电影数据集的配置类:

@Configuration
@EnableNeo4jRepositories(basePackages="org.xx.yy.movies.repositories")
public class MoviesDataSourceConfig {

    @Bean
    public org.neo4j.ogm.config.Configuration getConfiguration() {
        org.neo4j.ogm.config.Configuration config = new Builder()
                .uri("bolt://username:password@localhost:7687").
                build();
        return config;
    }

    @Bean
    public Neo4jTransactionManager transactionManager() {
        return new Neo4jTransactionManager(sessionFactory());
    }

    @Bean
    public SessionFactory sessionFactory() {
        return new SessionFactory(getConfiguration(), "org.xx.yy.movies.models");
    }
}

请注意，您需要在URI中指定用户名和密码... 这仍然是POC代码，但我将从spring.data.neo4j属性中提取它们以进行生产。

不再有警告信息！

我也遇到了同样的问题（使用SpringBoot 2.2.2以及依赖spring-boot-starter-data-neo4j）。我通过在主应用类上添加两个注释来消除这个警告，缩小了对实体/模型类的扫描范围：@SpringBootApplication。

@EnableNeo4jRepositories("my.project.reposoitory")
@EntityScan("my.project.model")

避免需要单独的@Config类/重写SpringBoot自动配置。请参阅文档。 更新： 将Spring Boot版本提升到2.2.4.RELEASE，因为我在使用Neo4jRepository声明方法时遇到了无法返回任何数据的问题。怀疑这与事务相关，将提出缺陷报告。
我已经按照一些设置教程使用了 @EnableNeo4jRepositories。再加上 @EntityScan，这样就解决了我的错误。 - Graham Lea

我解决这个错误的最简单方法是在application.properties文件中添加以下行：

logging.level.org.spring.data.neo4j.mapping.*=ERROR
