DatabaseConfiguration类型的文件DatabaseConfiguration.java中的neo4jServer方法必须覆盖或实现一个超类型“

分类: 技术问答 • 2022-07-11 11:49:45
问题描述：

我想在Neo4j图形数据库之上开发一个Java应用程序 对于这个应用程序，我想重新使用锅炉代码从Vlastaridis先生在Github上通过https://github.com/jhipster/jhipster-neo4j-app/tree/2a6fa89f8c8aa13dc7ea7856b4ee521efceeb7c7DatabaseConfiguration类型的文件DatabaseConfiguration.java中的neo4jServer方法必须覆盖或实现一个超类型“

这Neo4j的例子是Neo4j的旧版本2.xx的发展，我想更新数据库版本3.xx.因此我必须更新春天数据的Neo4j项目实施

因此我修改了POM.XML文件中的必要条目我使用了属性和依赖关系o f https://github.com/neo4j-examples/movies-java-spring-data-neo4j-4作为我的POM.XML文件中的修改示例。 据我所知，这个最重要的POM.XML实现应该使用Spring Boot来包含所有其他依赖项，包括必要的Spring Data Neo4j依赖项。然而，这似乎并非如此。 由于修改后的POM.XML，我最终在Eclipse和Maven中出现错误：“DatabaseConfiguration类型的文件DatabaseConfiguration.java中的方法neo4jServer必须覆盖或实现超类型。”

问题：如何修改锅炉板代码中的POM.XML以删除错误信息？

DatabaseConfiguration.java的实现看起来是这样的：

package com.mycompany.myapp.config; 

import org.neo4j.ogm.session.Session; 
import org.neo4j.ogm.session.SessionFactory; 
import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.context.annotation.Profile; 
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.data.repository.query.QueryLookupStrategy; 


@Configuration 
@Profile("!test") 
@EnableNeo4jRepositories(basePackages = "com.mycompany.myapp.repository", queryLookupStrategy = QueryLookupStrategy.Key.CREATE_IF_NOT_FOUND) 
public class DatabaseConfiguration extends Neo4jConfiguration { 

    private final Logger log = LoggerFactory.getLogger(DatabaseConfiguration.class); 

@Override 
@Bean 
public Neo4jServer neo4jServer() { 
    log.info("Initialising server connection"); 
    return new RemoteServer("http://localhost:7474", "neo4j", "1234"); 
} 

@Override 
@Bean 
public SessionFactory getSessionFactory() { 
    log.info("Initialising Session Factory"); 
    return new SessionFactory("com.mycompany.myapp.domain"); 
} 

@Override 
@Bean 
public Session getSession() throws Exception { 
    log.info("Initialising session-scoped Session Bean"); 
    return super.getSession(); 
}

}

我pom.xml文件看起来是这样。由于*的限制，我删除了这个POM.XML中的大部分非Neo4j相关属性和依赖关系。

答

您正在使用的版本4.1.1.RELEASE弹簧数据Neo4j的。在您的DatabaseConfiguration课程中，您正在延伸Neo4jConfiguration。你的问题就像错误说的那样，你想重写一个超类中不存在的方法。在SDN的版本4.1.1.RELEASE中，没有方法叫做neo4jServer你可以覆盖的方法（这个方法被删除了一些关于4.1.0.RELEASE的内容）

所以你可以做的是改变你在SDN上的配置正在使用版本 - 删除neo4jServer方法和使用这样的配置：

@Bean 
public SessionFactory getSessionFactory() { 
    return new SessionFactory(getConfiguration(), "com.mycompany.myapp"); 
} 

@Bean 
public Neo4jOperations neo4jTemplate() throws Exception { 
    return new Neo4jTemplate(getSession()); 
} 

@Bean 
public org.neo4j.ogm.config.Configuration getConfiguration() { 
    org.neo4j.ogm.config.Configuration config = new org.neo4j.ogm.config.Configuration(); 

    config.driverConfiguration().setDriverClassName("org.neo4j.ogm.drivers.http.driver.HttpDriver") 
      .setURI("http://localhost:7474") 
      .setCredentials("neo4j", "1234"); 

    return config; 
} 

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

另一种选择（我不建议）是在你的pom.xml改变SDN的版本

<spring-data-neo4j.version>4.0.0.RELEASE</spring-data-neo4j.version>
