Question

我几乎被困住了，我希望你们可以帮助我。不知怎的，我无法设法初始化我的春天语境。

我有这些不错的Bean配置类：

@Configuration
public class CoreConfig {

    @Bean
    public TeamService createService(TeamPersistenceService teamPersistenceService) {
    return new TeamEventHandler(teamPersistenceService);
    }
}

这一个：

@Configuration
@EnableJpaRepositories(basePackages = "de.ktv.persistence.repository", //
includeFilters = @ComponentScan.Filter(value = { TeamsRepository.class }, type =                            FilterType.ASSIGNABLE_TYPE))
@EnableTransactionManagement
public class PersistenceConfig {

    @Bean
    public TeamPersistenceService createService(TeamsRepository repository) {
    return new TeamPersistenceEventHandler(repository);
    }
}

在这个测试中，我想使用它们：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { CoreConfig.class, PersistenceConfig.class })
public class CoreIntegrationTest {

@Autowired
TeamService teamService;

@Test
public void addNewTeamToTheSystem() {

    //some test

}

PersistenceConfig.class我正在使用不同的测试，它工作正常。但不知怎的，这里结合了CoreConfig.class，它无法初始化。

这是我得到的错误：

org.springframework.beans.factory.NoSuchBeanDefinitionException：找不到类型为[de.ktv.core.services.TeamService]的限定bean 依赖：预计至少有1个bean有资格成为autowire 这种依赖的候选人。依赖注释： {@ org.springframework.beans.factory.annotation.Autowired（所需=真）}

我真的很感激任何帮助/提示。谢谢！

Answer 1

如果您没有指明相同的名称，则SpringContext无法绑定@autowired。默认情况下，bean名称将与方法名称相同，在这种情况下，他是不同的，2个选项：更改方法名称或添加属性名称！

选项1

@Bean(name = "teamService")
public TeamService createService(TeamsRepository repository) {
return new TeamPersistenceEventHandler(repository);
}

选项2

@Bean
public TeamService teamService(TeamsRepository repository) {
return new TeamPersistenceEventHandler(repository);
}

Answer 2

@Configuration
public class CoreConfig {
    @Autowired
    private TeamPersistenceService teamPersistenceService;

    @Bean
    public TeamService teamService() {
    return new TeamEventHandler(teamPersistenceService);
    }
}

这一个：

@Configuration
@EnableJpaRepositories(basePackages = "de.ktv.persistence.repository", //
includeFilters = @ComponentScan.Filter(value = { TeamsRepository.class }, type =                            FilterType.ASSIGNABLE_TYPE))
@EnableTransactionManagement
public class PersistenceConfig {
    @Autowired
    private TeamsRepository repository:

    @Bean
    public TeamPersistenceService teamPersistenceService() {
    return new TeamPersistenceEventHandler(repository);
    }
}

在这个测试中，我想使用它们：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { CoreConfig.class, PersistenceConfig.class })
public class CoreIntegrationTest {

@Autowired
TeamService teamService;

@Test
public void addNewTeamToTheSystem() {

    //some test

}
