Question

我正在使用Spring Boot配置neo4j数据库。我能够设置Spring Boot，它运行正常。但是当我配置neo4j时，它会抛出异常org.apache.http.client.HttpResponseException: No authentication header supplied。

日志存储如下：

配置类：

public class ApplicationConfiguration extends Neo4jConfiguration{

    @Bean
    public Configuration getConfiguration(){
        Configuration config = new Configuration();
        config.driverConfiguration()
            .setDriverClassName("org.neo4j.ogm.drivers.http.driver.HttpDriver")
            .setURI("http://neo4j:welcome*123@localhost:7474");
        return config;
    }

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

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

Answer 1

Spring Boot具有配置属性列表，可以在＆＃34; application.properties＆＃34;中设置。文件。

设置这些可能会解决问题：

spring.data.neo4j.username=neo4j (default user)    
spring.data.neo4j.password=neo4j (default password)

Answer 2

这需要在标头中进行身份验证，或者您可以禁用身份验证尝试编辑neo4j.conf install dir bin / neo4j.conf 并取消注释这一行

# Whether requests to Neo4j are authenticated.
# To disable authentication, uncomment this line
dbms.security.auth_enabled=false

或启用neo DBMS连接器

# HTTP Connector. There must be exactly one HTTP connector.
dbms.connector.http.enabled=true
#dbms.connector.http.listen_address=:7474

org.apache.http.client.HttpResponseException：未提供身份验证标头
