如何使用带有 IO Platform 1.1.3 的 Spring Data Neo4J 4 制作嵌入式服务器？
How can make an embedded server with Spring Data Neo4J 4 with IO Platform 1.1.3?
我正在尝试在 Spring Data Neo4J 4 上启动一个新应用程序。不过我在使用基本配置时遇到了一些问题。

我目前没有 Neo4j 的配置，所以这可能是问题的一部分，尽管我在数据共享版本和其他方面遇到过问题。
我没有配置，因为文档说
InProcessServer is useful for test and development environments,
InProcessServer 在 4.0 中不作为 class 存在，我还没有设置远程服务器。
这是我目前对 pom.xml 的尝试，但我不认为它是完整的。

如何让嵌入式服务器在 IO Platform 1.1.3 上使用 Spring Data Neo4j 4？

我已经稍微更新了我的依赖项。

我确实复制了配置
package com.xenoterracide.rpf.config;
import org.neo4j.ogm.session.Session;
import org.neo4j.ogm.session.SessionFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Scope;
import org.springframework.context.annotation.ScopedProxyMode;
import org.springframework.data.neo4j.config.Neo4jConfiguration;
import org.springframework.data.neo4j.server.InProcessServer;
import org.springframework.data.neo4j.server.Neo4jServer;
@Configuration
public class Neo4JDevelopmentConfig extends Neo4jConfiguration {
@Bean
@Override
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public Session getSession() throws Exception {
return super.getSession();
}
@Bean
@Override
public Neo4jServer neo4jServer() {
return new InProcessServer();
}
@Bean
@Override
public SessionFactory getSessionFactory() {
return new SessionFactory("com.xenoterracide.rpf");
}
}
但这只会导致一组不同的例外情况

在 search.maven.org 上快速搜索完全限定的 class 名称表明您很可能遗漏了测试 JAR：

}
Spring 引导的日志记录似乎关闭，例如默认情况下未设置颜色，并且未记录自动配置。我也收到了这些警告，但它们似乎没有任何影响。

我正在尝试在 Spring Data Neo4J 4 上启动一个新应用程序。不过我在使用基本配置时遇到了一些问题。

我目前没有 Neo4j 的配置，所以这可能是问题的一部分，尽管我在数据共享版本和其他方面遇到过问题。
我没有配置，因为文档说
InProcessServeris useful for test and development environments,
InProcessServer 在 4.0 中不作为 class 存在，我还没有设置远程服务器。
这是我目前对 pom.xml 的尝试，但我不认为它是完整的。

如何让嵌入式服务器在 IO Platform 1.1.3 上使用 Spring Data Neo4j 4？
更新

我确实复制了配置
package com.xenoterracide.rpf.config;
import org.neo4j.ogm.session.Session;
import org.neo4j.ogm.session.SessionFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Scope;
import org.springframework.context.annotation.ScopedProxyMode;
import org.springframework.data.neo4j.config.Neo4jConfiguration;
import org.springframework.data.neo4j.server.InProcessServer;
import org.springframework.data.neo4j.server.Neo4jServer;
@Configuration
public class Neo4JDevelopmentConfig extends Neo4jConfiguration {
@Bean
@Override
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public Session getSession() throws Exception {
return super.getSession();
}
@Bean
@Override
public Neo4jServer neo4jServer() {
return new InProcessServer();
}
@Bean
@Override
public SessionFactory getSessionFactory() {
return new SessionFactory("com.xenoterracide.rpf");
}
}
但这只会导致一组不同的例外情况

}
Spring 引导的日志记录似乎关闭，例如默认情况下未设置颜色，并且未记录自动配置。我也收到了这些警告，但它们似乎没有任何影响。
