Question

我目前正在使用Spring Boot在Vaadin中开发一个项目，我想重用另一个项目中的一些存储库而不将该项目作为依赖项添加，但是当我尝试运行该项目时，我收到此错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataCache': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.myproject.vas.aftersales.repository.AfterSalesFileRepository com.myproject.vas.DataCache.afterSalesFileRepository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'afterSalesFileRepository': Invocation of init method failed; nested exception is java.lang.AbstractMethodError: org.springframework.data.repository.core.support.RepositoryFactorySupport.getTargetRepository(Lorg/springframework/data/repository/core/RepositoryInformation;)Ljava/lang/Object;

我在网上搜索了解决方案，并尝试了从切换包到更改依赖关系版本的所有内容......

我的存储库：

@Component
public interface AfterSalesFileRepository extends JpaRepository<AfterSalesFile, Integer> {

    @Query("select m from AfterSalesFile m " +
            "where m.id=:id and m.status is not 'INACTIVE'")
    AfterSalesFile findOne(@Param("id") final Integer id);
}

尝试初始化和使用存储库的类：

@Component
public class DataCache {

    @Getter(AccessLevel.PRIVATE)
    private CustomerIdentityRepository customerIdentityRepository;

    @Autowired
    private AfterSalesFileRepository afterSalesFileRepository;

    @Autowired
    public DataCache(CustomerIdentityRepository customerIdentityRepository) {
        this.customerIdentityRepository = customerIdentityRepository;

    }

...

    public List<AfterSalesFile> getAllAftersales() {
        return afterSalesFileRepository.findAll();
    }
}

我的数据库配置：

@Configuration
public class DatabaseConfiguration implements EnvironmentAware {

    private RelaxedPropertyResolver jpaPropertyResolver;
    @Autowired(required = false)
    private PersistenceUnitManager persistenceUnitManager;

    @Override
    public void setEnvironment(Environment environment) {
        this.jpaPropertyResolver = new RelaxedPropertyResolver(environment, "spring.jpa.");
    }

    @Bean
    @DependsOn("jdbcTemplate")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        if (persistenceUnitManager != null) {
            entityManagerFactoryBean
                    .setPersistenceUnitManager(persistenceUnitManager);
        }
        entityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter);
        entityManagerFactoryBean.setDataSource(dataSource);
        entityManagerFactoryBean.setPackagesToScan("com.myproject.vas.aftersales");
        entityManagerFactoryBean.getJpaPropertyMap().putAll(jpaPropertyResolver.getSubProperties("properties."));
        Map<String, Object> properties = entityManagerFactoryBean.getJpaPropertyMap();
        properties.put("hibernate.ejb.naming_strategy", jpaPropertyResolver.getProperty("hibernate.naming-strategy", SpringNamingStrategy.class.getName()));
        properties.put("hibernate.hbm2ddl.auto", jpaPropertyResolver.getProperty("hibernate.ddl-auto", "none"));
        properties.put("hibernate.show_sql", jpaPropertyResolver.getProperty("hibernate.show_sql", "false"));
        return entityManagerFactoryBean;
    }
}

我的主要人物：

    @SpringBootApplication
    @EnableJpaRepositories(basePackages = {"com.myproject.vas.aftersales.repository"})
    @ComponentScan(basePackages = {"com.myproject"})
    public class VasApplication {
        public static void main(String[] args) {
            SpringApplication.run(VasApplication.class, args);
        }
    }

我们已经运行了一个Cassandra数据库，这将添加一个mssql数据库。一位同事指出它尝试使用Cassandra而不是mssql：

Answer 1

几乎在每种情况下，

AbstractMethodError都是非匹配依赖项的结果。当两个具有不兼容版本的库最终出现在类路径AbstractMethodError上时。

在您的情况下，问题可能是由您指定的几个与持久性相关的依赖项引起的。默认情况下，使用时不应指定JPA / Hibernate依赖项：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

例如，如果您检查this tutorial，您将看到正在运行的应用程序的final pom仅包含驱动程序jar（h2），而不包括持久性的boot-starter依赖项。

Answer 2

尝试从AfterSalesFileRepository中删除@Component。如果你有@ComponentScan启用，则spring boot会自动为扩展JpaRepository的任何接口创建存储库实现

Answer 3

当您查看依赖树时，您将看到您正在混合Spring Boot 1.2.3和1.3.0中的Spring Boot jar版本。切勿混合版本。因此，您还混合了Spring 4.1.6和4.2.3的版本，这些版本总是很危险。

对于初学者，请删除spring-data-jpa，hibernate和spring-security依赖项，并使用Spring Security for Spring（spring-boot-starter-security），而不是手动添加依赖项。（初学者带来适当的版本）。

同时删除spring-test和junit个依赖项，并将spring-boot-starter-test与<scope>test</scope>一起用作依赖项。

接下来有些东西正在为spring-boot-starter-log4j提供弹簧启动1.2.3修复此问题，以便为启动版本使用正确的版本。

您还想再次使用cassandra使用启动器spring-boot-starter-data-cassandra。

还有一个旧的spring-security-crypto jar被拉入（3.2.7而不是4.0.3），这也会导致其他jar的旧依赖。

使用启动器可以避免指定版本（或者可以防止您添加错误的版本）。
