Question

我正在使用示例项目SDN4-northwind（https://github.com/amorgner/sdn4-northwind）中的Spring Data Neo4j 4（SDN4），当我尝试获取Neo4jTemplate bean时，我得到这样的错误消息。有谁知道如何从SDN4获取Neo4jTemplate bean？

Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.data.neo4j.template.Neo4jTemplate] is defined
at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:371)
at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:331)
at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:968)
at org.neo4j.example.northwind.Run.main(Run.java:34)

这是配置文件

package org.neo4j.example.northwind;

import org.neo4j.ogm.session.Session;
import org.neo4j.ogm.session.SessionFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.neo4j.config.Neo4jConfiguration;
import org.springframework.data.neo4j.repository.config.EnableNeo4jRepositories;
import org.springframework.data.neo4j.server.Neo4jServer;
import org.springframework.data.neo4j.server.RemoteServer;
import org.springframework.transaction.annotation.EnableTransactionManagement;


@Configuration
@EnableNeo4jRepositories("org.neo4j.example.northwind.repository")
@EnableTransactionManagement
public class AppContext extends Neo4jConfiguration {

public static final String NEO4J_HOST = "http://localhost:";
public static final int    NEO4J_PORT = 7474;

@Override
public SessionFactory getSessionFactory() {
    System.setProperty("username", "neo4j");
    System.setProperty("password", System.getProperty("password","osp"));
    return new SessionFactory("org.neo4j.example.northwind.model");
}

@Bean
@Override
public Neo4jServer neo4jServer() {
    return new RemoteServer(NEO4J_HOST + NEO4J_PORT);
}

@Bean
@Override
//@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public Session getSession() throws Exception {
    return super.getSession();
}

}

到@Bean public Neo4jOperations getNeo4jTemplate() throws Exception { return new Neo4jTemplate(getSession()); }然后再到AppContext

如何在SDN4中获得Neo4jTemplate
