为什么我的代码抛出一个“bean非托管异常”？

Question

在我开始添加更多存储库之前，我的代码只使用一个存储库包就可以正常工作

主数据源配置类：

@EnableTransactionManagement
@EnableJpaRepositories(basePackages = {"com.example.resource.akademiks.waec.obj.dao",
        "com.example.resource.akademiks.waec.theory.dao", "com.example.resource.akademiks.waec.theory.answer.dao"},
 entityManagerFactoryRef = "akademiksEntityManagerFactory",
 transactionManagerRef = "akademiksTransactionManager")
public class AkademiksDbConfig {
    
    @Bean
    @Primary
    @ConfigurationProperties("spring.datasource.waecakademiks")
    public DataSourceProperties akademiksDataSourceProperties() {
        
        return new DataSourceProperties();
    }
    
    @Primary
    @Bean
    @ConfigurationProperties("spring.datasource.waecakademiks")
    public DataSource akademiksDataSource() {
        
        return akademiksDataSourceProperties().initializeDataSourceBuilder()
                .type(HikariDataSource.class).build();
        
    }
    
    
    @Primary
    @Bean(name = "akademiksEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean 
    akademiksEntityManagerFactory(EntityManagerFactoryBuilder builder) {
        
        return builder
                .dataSource(akademiksDataSource())
                .packages("com.example.resource.akademiks.waec.obj.entity")
                .packages("com.example.resource.akademiks.waec.theory.questions.entity")
                .packages("com.example.resource.akademiks.waec.theory.answer.entity")
                .build();
                
    }
    
    @Primary
    @Bean
    public PlatformTransactionManager akademiksTransactionManager(
            @Qualifier("akademiksEntityManagerFactory")
            LocalContainerEntityManagerFactoryBean akademiksEntityManagerFactory
            ) {
        return new JpaTransactionManager(akademiksEntityManagerFactory.getObject());
    }
    
}

存储库：

package com.example.resource.akademiks.waec.obj.dao;

@Repository
@RepositoryRestResource(collectionResourceRel = "chemistry", path = "chemistry")
public interface WaecChemistryObjRepo extends JpaRepository<WaecChemistryObj, Integer> {

服务层：

 package com.example.resource.akademiks.waec.theory.chemistry.service;

public interface WaecChemistryTheoryService {}

服务实施：

 @Service
   public class WaecChemistryObjServiceImpl implements WaecChemistryObjService {
  @Autowired
 private WaecChemistryObjOptionRepo chemistryOptionRepo;

实体类：

package com.example.resource.akademiks.waec.obj.entity;

@Entity
@Table(name = "WaecChemistryObjAnswer")
public class WaecChemistryObjAnswer {

其他实体和存储库已被排除在外。

packages方法采用varargs参数：

EntityManagerFactoryBuilder.Builder packages(String... packagesToScan)

您可以调用它3次，而不是在一次调用中传递3个包。

更一般地说：利用自动配置并遵循约定而不是配置方法，如注释中所建议的。
