尝试在 2 类中使用我的服务：org.springframework.beans.factory.BeanCreationException：使用名称创建 bean 时出错

Question

尝试在 2 类中使用我的 AccountService (@Service) 得到这个错误：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'accountService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.mz.springContextWorld.repositories.AccountRepository com.mz.springContextWorld.services.AccountService.accountRepository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'accountRepository': Cannot resolve reference to bean 'neo4jTemplate' while setting bean property 'neo4jTemplate'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.data.neo4j.config.Neo4jConfiguration#0': Cannot resolve reference to bean 'graphDatabaseService' while setting bean property 'graphDatabaseService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'graphDatabaseService': FactoryBean threw exception on object creation; nested exception is java.lang.RuntimeException: Error starting org.neo4j.kernel.EmbeddedGraphDatabase, /home/matthias/IdeaProjects/springContextWorld/target/neo4j-db-plain

这是我的 github 回购：https://github.com/mzober/springContextWorld/tree/CollectorManager_ErrorBranch

这里是我的 accountService 的使用：

@Autowired 
AccountService accountService;

public LoginPanel() {
 //errorline here
          this.accountService=GuiFactory.getInstance().mainWindow().getAccountService();


          init();

          addComponents();
    }

...

@Autowired
AccountService accountService;


public RegistryAndLoginListener() {

     //no error here

   accountService=GuiFactory.getInstance().mainWindow().getAccountService();

}

...从上下文配置中获取帐户服务：

<context:annotation-config/>
<context:spring-configured/>

<context:component-scan base-package="com.mz.springContextWorld.domain"/>
<context:component-scan base-package="com.mz.springContextWorld.repositories"/>
<context:component-scan base-package="com.mz.springContextWorld.gui.listener"/>
<context:component-scan base-package="com.mz.springContextWorld.gui.components"/>
<context:component-scan base-package="com.mz.springContextWorld.gui.creational"/>
<context:component-scan base-package="com.mz.springContextWorld.services"/>

<neo4j:config storeDirectory="target/neo4j-db-plain"
              base-package="com.mz.springContextWorld.domain"/>
<neo4j:repositories base-package="com.mz.springContextWorld.repositories"/>

<tx:annotation-driven />

...在 MainWindow 中加载配置（我的 Spring-Data-Neo4j 演示应用程序）

@Autowired
public AccountService accountService;

public MainWindow() {
    super(PROJECTNAME);
    context= new ClassPathXmlApplicationContext("spring/spring-config.xml");
    accountService=(AccountService)context.getBean("accountService");
    ...
 }
 public AccountService getAccountService(){return this.accountService;}

账户服务：

 @Service
 @Transactional
 public class AccountService {

@Autowired
AccountRepository accountRepository;


public AccountService(){

}

@Transactional
public Iterable<Account> getAll() {
    return accountRepository.findAll();
}...

这是我的 pom.xml:

感谢您的帮助

您的 neo4j 数据库似乎无法启动。检查最后一行日志：Error starting org.neo4j.kernel.EmbeddedGraphDatabase, /home/matthias/IdeaProjects/springContextWorld/target/neo4j-db-plain
