Question

我的应用程序只测试环境是否基本正常工作。因此我设置了一个对应于“Hello Worlds”示例的测试类，该示例可以在SpringSource的gitHub存储库中找到。 Neo4j作为静态Web应用程序包含在内并运行嵌入式。 Web接口不是必需的。问题是，当我开始通过Junit运行测试用例时，我得到这样的错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'GalaxyServiceTests': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private GalaxyService GalaxyServiceTests.galaxyService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [GalaxyService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

我的应用程序配置就像这样

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:neo4j="http://www.springframework.org/schema/data/neo4j"
        xsi:schemaLocation="

    <constructor-arg index="1">
        <map><entry key="enable_remote_shell" value="true"/></map>
    </constructor-arg>
</bean>
<!-- <bean id="serverWrapper" class="org.neo4j.server.WrappingNeoServerBootstrapper"  -->
<!--    init-method="start" destroy-method="stop"> -->
<!--    <constructor-arg ref="graphDatabaseService"/> -->
<!-- </bean> -->
</beans>

测试类是简单的

@ContextConfiguration( "file:c:/Users/ben/Dropbox/Semester 6/VM Graphentheorie/devEnv/bodega/application-context.xml")

@RunWith(SpringJUnit4ClassRunner.class)
@Transactional
public class GalaxyServiceTests {

//  @Autowired
//  private GalaxyService galaxyService;

    @Autowired
    private Neo4jTemplate template;

    @Rollback(false)
    @BeforeTransaction
    public void cleanUpGraph() {
        Neo4jHelper.cleanDb(template);
    }

    @Test
    public void allowWorldCreation(){
//      GraphDatabaseService     graphDatabaseService =  new GraphDatabaseFactory().newEmbeddedDatabase( "target/graph.db" );
//      Node abc = graphDatabaseService.createNode();
//      abc.setProperty("name","ben");

        World abc = new World("Erde",1);
        template.save(abc);

我的pom看起来像这样：

        </dependency>

由于即时通讯与neo4j有关，我无法解决此错误。如果有人得到提示或一些建议 - 提前谢谢

修改我将spring-data的依赖关系从2.2.0.BUILD-SNAPSHOT更改为2.2.0.RELEASE ..现在neo4j正在运行，直到错误传递给控制台：

21:11:48.196 [main] ERROR o.s.test.context.TestContextManager - Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@7e26f5a7] to prepare test instance [GalaxyServiceTests@64d74895]
java.lang.IllegalStateException: Failed to load ApplicationContext

EDIT2 我已经发布了存储库 http://github.com/BenMatheja/bodega

EDIT3 有关application-context.xml路径的东西搞砸了。我用@ContextConfiguration( locations = {"classpath:/META-INF/application-context.xml"})

解决了这个问题

我正处于异常

的程度

找不到依赖项类型[start.GalaxyService]的限定bean：预计至少有1个豆有资格成为autowire候选人这种依赖

每次我现在运行JUnit4测试时都会抛出

。

EDIT4 我设法让它在昨天工作。应用程序上下文的某些部分非常混乱。

<context:spring-configured/>
<context:annotation-config/>
<context:component-scan base-package="components"/>
<neo4j:config graphDatabaseService="graphDatabaseService"/>
<neo4j:config storeDirectory="target/graph.db"/>
<neo4j:repositories base-package="Repositories"/>

这是我工作的app-context的片段。此外，我错过了将@Service附加到GalaxyService类。

现在一切正常。这可能会帮助遇到同样问题的人。
