title: Neo4j Liquigraph datasource - expected single matching bean but found 2
body: <p>In SpringBoot Maven application I have configured two datasources - one Neo4j for Liquigraph</p>
  <pre><code>@Bean
  @LiquigraphDataSource
  public DataSource neo4jDataSource() {
      final HikariConfig config = new HikariConfig();
      config.setJdbcUrl(jdbcServerDatabaseUri);
      config.setUsername(username);
      config.setPassword(password);
      return new HikariDataSource(config);
  }
  </code></pre>
  <p>and one PostgreSQL for Liquibase</p>
  <pre><code>@Bean
  @LiquibaseDataSource
  public DataSource postgreSQLDataSource() {
      DataSource dataSource = DataSourceBuilder.create()
              .username(username)
              .password(password)
              .url(databaseUrl)
              .build();
      return dataSource;
  }
  </code></pre>
  <p>but during the application start up it fails with the following exception:</p>
  <pre><code>Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'matrixServiceImpl': Unsatisfied dependency expressed through field 'session'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.data.neo4j.repository.config.Neo4jOgmEntityInstantiatorConfigurationBean#0': Cannot resolve reference to bean 'sessionFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [com/decisionwanted/domain/configuration/Neo4jConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.neo4j.ogm.session.SessionFactory]: Factory method 'sessionFactory' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.liquigraph.spring.starter.LiquigraphAutoConfiguration$LiquigraphConfiguration': Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.liquigraph.spring.starter.LiquigraphAutoConfiguration$LiquigraphConfiguration$$EnhancerBySpringCGLIB$$cb17993a]: Constructor threw exception; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'javax.sql.DataSource' available: expected single matching bean but found 2: postgreSQLDataSource,neo4jDataSource
