이름이 같은 두 개의 콩이있는 경우가 저에게 보입니다. 그러나 "entityManagerFactoryBean"에 대한 코드베이스를 검색 할 때 다른 참조가 없었습니다.

@Bean(name="dataSource") 
public DataSource getDataSource() { 
    if (this.dataSource == null) { 
     this.dataSource = new DriverManagerDataSource(); 

     dataSource.setDriverClassName(env.getProperty(DRIVER_CLASS_NAME_PROPERTY)); 
     dataSource.setUrl(env.getProperty(DB_URL_PROPERTY)); 
     dataSource.setUsername(env.getProperty(USERNAME_PROPERTY)); 
     dataSource.setPassword(env.getProperty(PASSWORD_PROPERTY)); 
    } 
    return this.dataSource; 
} 

@Bean(name="entityManagerFactoryBean") 
public LocalContainerEntityManagerFactoryBean configureEntityManagerFactory() { 

    LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean(); 
    entityManagerFactoryBean.setDataSource(getDataSource()); 
    entityManagerFactoryBean.setPackagesToScan("com.global.us.app.model.db"); 
    entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter()); 

    Properties jpaProperties = new Properties(); 
    jpaProperties.put(org.hibernate.cfg.Environment.DIALECT, env.getProperty(org.hibernate.cfg.Environment.DIALECT)); 
    jpaProperties.put(org.hibernate.cfg.Environment.SHOW_SQL, env.getProperty(org.hibernate.cfg.Environment.SHOW_SQL)); 
    jpaProperties.put(org.hibernate.cfg.Environment.HBM2DDL_IMPORT_FILES_SQL_EXTRACTOR, env.getProperty(org.hibernate.cfg.Environment.HBM2DDL_IMPORT_FILES_SQL_EXTRACTOR)); 
    entityManagerFactoryBean.setJpaProperties(jpaProperties); 

    return entityManagerFactoryBean; 
} 

@Override 
@Bean() 
@DependsOn("entityManagerFactoryBean") 
public PlatformTransactionManager annotationDrivenTransactionManager() { 
    JpaTransactionManager jpa = new JpaTransactionManager(); 
    jpa.setEntityManagerFactory(configureEntityManagerFactory().getObject()); 
    return jpa; 
} 

누군가이 오류가 실제로 무엇을 의미하는지 설명 할 수 있습니까? 중복 된 이름을 가진 빈이 아니라는 것을 알기 때문에, 나는 그것의 말씨로 혼란스러워합니다.

Answer 1

EntityManagerFactory 및 PlatformTransactionManager을 만드는 방법을 변경하십시오.

@Bean(name="entityManagerFactoryBean") 
public EntityManagerFactory configureEntityManagerFactory() { 

    LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean(); 
    entityManagerFactoryBean.setDataSource(getDataSource()); 
    entityManagerFactoryBean.setPackagesToScan("com.global.us.app.model.db"); 
    entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter()); 

    Properties jpaProperties = new Properties(); 
    jpaProperties.put(org.hibernate.cfg.Environment.DIALECT, env.getProperty(org.hibernate.cfg.Environment.DIALECT)); 
    jpaProperties.put(org.hibernate.cfg.Environment.SHOW_SQL, env.getProperty(org.hibernate.cfg.Environment.SHOW_SQL)); 
    jpaProperties.put(org.hibernate.cfg.Environment.HBM2DDL_IMPORT_FILES_SQL_EXTRACTOR, env.getProperty(org.hibernate.cfg.Environment.HBM2DDL_IMPORT_FILES_SQL_EXTRACTOR)); 
    entityManagerFactoryBean.setJpaProperties(jpaProperties); 

    entityManagerFactoryBean.afterPropertiesSet(); 

    return (EntityManagerFactory) entityManagerFactoryBean.getObject(); 
} 


@Override 
@Bean() 
@DependsOn("entityManagerFactoryBean") 
public PlatformTransactionManager annotationDrivenTransactionManager() { 
    JpaTransactionManager jpa = new JpaTransactionManager(); 
    jpa.setEntityManagerFactory(configureEntityManagerFactory()); 
    return jpa; 
}
