Spring Neo4j - 自動裝入庫返回null

Question

我對Spring很陌生（Neo4j方面），並且遇到問題@AutoWire-我的存儲庫。 這是我的回購協議：

package org.jarivm.relationGraph.objects.repositories; 
public interface EmployeeRepository extends GraphRepository<Employee> { 
    @Query("MATCH a=(:Employee)-[:WORKED_ON]->(p:Project) WHERE id(p)={0} RETURN a") 
    Iterable<Employee> getTeamMates(Project client); 
} 

我的測試類：

package org.jarivm.relationGraph; 

import org.apache.commons.collections4.set.ListOrderedSet; 
import org.jarivm.relationGraph.objects.domains.Employee; 
import org.jarivm.relationGraph.objects.domains.Project; 
import org.jarivm.relationGraph.objects.repositories.EmployeeRepository; 
import org.jarivm.relationGraph.utilities.NodeProperties; 
import org.junit.After; 
import org.junit.Before; 
import org.junit.FixMethodOrder; 
import org.junit.Test; 
import org.junit.runners.MethodSorters; 
import org.springframework.beans.factory.annotation.Autowired; 

import java.util.Iterator; 


/**

@FixMethodOrder(MethodSorters.JVM) 
public class Tests extends Application { 
    @Autowired 
    private Facade facade; 
    @Autowired 
    private EmployeeRepository employeeRepository; 

    @Before 
    public void setUp() throws Exception { 
     facade = new Facade(); 
    } 

    @After 
    public void tearDown() throws Exception { 
     facade.tearDown(); 
    } 

/* 
    @Test 
    public void persistedEmployeeShouldBeRetrievableFromGraphDB() { 
     Employee employee = new Employee("john", "adams"); 
     //System.out.println(session.getTransaction().status()); 
     if (!facade.findEmployeeByProperty("name", employee.getName()).iterator().hasNext()) { 
      facade.commit(employee); 

      Employee foundHim = facade.findEmployeeByProperty("name", employee.getName()).iterator().next(); 
      assert foundHim.getId().equals(employee.getId()); 
      assert foundHim.getName().equals(employee.getName()); 
     } 
    } 

    @Test 
    public void persistedChainShouldBeRetrievableFromGraphDB() { 
     Employee employee = new Employee("john", "myles"); 
     Client client = new Client(); 
     Sector sector = new Sector(); 
     Project project = new Project(); 
     client.setName("Real Dolmen");

     facade.commit(project); 

     Client foundHim = facade.findClientByProperty("name", client.getName()).iterator().next(); 
     assert foundHim.getId().equals(client.getId()); 
     assert foundHim.getName().equals(client.getName()); 
    } 


    @Test 
    public void projectShouldBeInsertableAlone() { 
     Project project = new Project();

     Client foundHim = facade.findClientByProperty("name", client.getName()).iterator().next(); 
     assert foundHim.getId().equals(client.getId()); 
    }*/ 

    @Test 
    public void createdNodesShoudBeEditable() { 
     Iterator<Employee> employees = facade.findEmployeeByProperty("name", "john").iterator(); 
     Project project = facade.findProjectByProperty("name", "random").iterator().next(); 
     while (employees.hasNext()) { 
      Employee e = employees.next(); 
      if (project.getTeam() == null) 
       project.setTeam(new ListOrderedSet<Employee>()); 
      project.getTeam().add(e); 
     } 
     facade.commit(project); 
    } 


    package org.jarivm.relationGraph; 

    @Autowired 
    private EmployeeRepository employeeRepository; 

    @Test 
    public void teamMatesShouldBeViewable() { 
     Project p = facade.findProjectByProperty("name", "Matsoft").iterator().next(); 
     System.out.println(p); 
     System.out.println(employeeRepository); 
     Iterable<Employee> e = employeeRepository.getTeamMates(p); 
     System.out.println(e.iterator()); 
    } 
} 

和我Application.java類：

package org.jarivm.relationGraph; 

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.transaction.annotation.EnableTransactionManagement; 

/** 
* @author Jari Van Melckebeke 
* @since 23.09.16 
*/ 
@EnableTransactionManagement 
@ComponentScan(basePackages = {"org.jarivm.relationGraph"}) 
@Configuration 
@EnableNeo4jRepositories(basePackages = "org.jarivm.relationGraph.objects.repositories.EmployeeRepository") 
public class Application extends Neo4jConfiguration { 

public static final String URL = System.getenv("NEO4J_URL") != null ? System.getenv("NEO4J_URL") : "http://localhost:7474"; 

@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(URL) 
    .setCredentials("neo4j", "mypassword"); 
    return config; 
} 

@Override 
public SessionFactory getSessionFactory() { 
    return new SessionFactory(getConfiguration(), "org.jarivm.relationGraph.objects.domains"); 
} 
} 

的@autowire也從未與該程序工作，所以我做的不知道什麼問題是... 感謝提前， Jari Van Melckebeke

我覺得你的測試類不應該擴展應用，而是與RunsWith註解 - 像（未經測試）：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(classes=org.jarivm.relationGraph.Application.class, loader=AnnotationConfigContextLoader.class 
public class Tests { 

瞭解更多信息，請參閱標題集成測試與@Configuration類部分：
