Spring Boot初始化中的BeanCreationException问题排查

Question

我有这个错误：

@EnableJpaRepositories declared on 

    JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Cannot create inner bean '(inner bean)#7ff8fb20' of type [org.springframework.orm.jpa.SharedEntityManagerCreator] while setting bean property 'entityManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#7ff8fb20': Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' available

还有这个班级：

@Configuration
public class JpaConfig {

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) {
        LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
        factoryBean.setDataSource(dataSource);
        factoryBean.setPersistenceUnitName("soib-kw-backoffice-entities");
        factoryBean.setPackagesToScan("com.soib.kwbo.model");
        factoryBean.setJpaVendorAdapter(jpaVendorAdapter);

        Properties jpaProperties = new Properties();
        jpaProperties.setProperty("eclipselink.target-database", "org.eclipse.persistence.platform.database.OraclePlatform");
        jpaProperties.setProperty("eclipselink.target-server", "WebLogic");
        jpaProperties.setProperty("eclipselink.logging.level", "WARNING");
        jpaProperties.setProperty("eclipselink.logging.level.sql", "WARNING");
        jpaProperties.setProperty("eclipselink.logging.logger", "DefaultLogger");
        jpaProperties.setProperty("eclipselink.cache.shared.default", "false");
        jpaProperties.setProperty("eclipselink.weaving", "false");
        jpaProperties.setProperty("eclipselink.jdbc.fetch-size", "200");

        factoryBean.setJpaProperties(jpaProperties);

        return factoryBean;
    }

    @Bean
    public JpaVendorAdapter jpaVendorAdapter() {
        EclipseLinkJpaVendorAdapter vendorAdapter = new EclipseLinkJpaVendorAdapter();
        vendorAdapter.setShowSql(false);
        vendorAdapter.setGenerateDdl(false);
        vendorAdapter.setDatabasePlatform("org.eclipse.persistence.platform.database.OraclePlatform");
        return vendorAdapter;
    }
}

尝试添加这个

@EnableJpaRepositories(basePackages = "com.soib.kwbo.repository")

并检查您的数据源是否配置正确。 ：D
