Hi Team,
We have installed neo4j (neo4j-community-3.4.7-unix.tar) on a Server 1 and
our spring boot application deployed on server 2 is using that neo4j
database.
We often getting connection timeout issue in our application and
immediately on next try it is working fine.
Connection time out is not bcoz of long inactive time.
Though we are using application regressively, we are getting connection
timeout suddenly in between and on immediate next try it is working fine.
This is the neo4j property details given in our spring boot application
running on server 2.
spring.data.neo4j.uri=bolt://X.X.X.X:17687
spring.data.neo4j.username=neo4j
spring.data.neo4j.password=xxxxxx
And below is the configuration file we used in our applicaiton to create
the connection.
@EnableNeo4jRepositories(basePackages = "com.metadata.dao",
sessionFactoryRef = "userSessionFactory", transactionManagerRef =
"userTransactionManager")
@Configuration
@EnableTransactionManagement
public class Neo4jConfiguration {
@Value("${spring.data.neo4j.uri}")
private String url;
@Value("${spring.data.neo4j.username}")
private String userName;
@Value("${spring.data.neo4j.password}")
private String password;
@Bean(name = "userSessionFactory")
@Primary
public SessionFactory bUserSessionFactory() {
return new SessionFactory(bUserconfiguration(), "com.metadata.dao.entity");
}
@Bean
public org.neo4j.ogm.config.Configuration bUserconfiguration() {
org.neo4j.ogm.config.Configuration configuration = new
org.neo4j.ogm.config.Configuration.Builder().uri(url)// "bolt://localhost"
.credentials(userName, password)// "user", "secret")
.build();
return configuration;
}
@Bean
public Neo4jTransactionManager bUserTransactionManager() {
return new Neo4jTransactionManager(bUserSessionFactory());
}
}
And attached is the neo4j connection time out logs we got in our
application logs.
Please help me to resolve the issue. Kindly let me know if you need any
additional information.
