我在Springboot中使用Spring Data Neo4j，并且该应用程序正常工作。

但是，我在启动时会发出很多警告，如果可能的话，我想摆脱它。

是什么让它如此不开心？

答案 0 :(得分：3)

我遇到了同样的问题，两天后，我终于明白了...

我的pom.xml看起来像这样：

spring.data.neo4j.open-in-view=false
spring.data.neo4j.uri=bolt://localhost
spring.data.neo4j.username=neo4j
spring.data.neo4j.password=xxx

通常，您将在应用程序属性中拥有用户名和密码：

@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");
    }
}

您还将获得启用呼叫：

@ EnableNeo4jRepositories

默认情况下，似乎Neo4j代码正在扫描应用程序中的所有类，但是您可以覆盖此行为：

  1. 创建一个配置类并将您的EnableNeo4jRepositories移到那里
  2. 指定您的回购基本软件包
  3. 指定您的模型基本包装

现在Neo4j代码知道只扫描回购和模型包。这是我的Movie数据集的配置类：

dirname=$1
files=$(ls $dirname)

for file in $files
do
wc -c $file
done

请注意，您需要在uri中指定用户名和密码...这仍然是POC代码，但我将把它们从spring.data.neo4j属性中拉出来进行生产化。

没有更多警告消息！

答案 1 :(得分：2)

有同样的问题（依赖项为spring-boot-starter-data-neo4j的SpringBoot 2.2.2）。通过在主要的@SpringBootApplication带注释的应用程序类中添加 both 注释，摆脱了警告/缩小了对实体/模型类的扫描范围：

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

避免需要单独的@Config类/替代SpringBoot自动配置。请参见docs。

更新： 由于我在从2.2.4.RELEASE声明式方法返回任何数据时遇到问题，因此将Spring Boot版本更改为Neo4jRepository。怀疑这与tx有关，将引发缺陷。

答案 2 :(得分：-1)

我为我的应用程序解决此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
