您能告诉我如何修复此问题并将实体持久化到数据存储中吗？您的问题是由于配置错误，HibernateJavaEndorapter不在Spring上下文中，因此您必须像Spring Bean一样声明它，示例如下：
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource);
em.setPackagesToScan(new String[] { "property.entity" });
em.setJpaVendorAdapter(vendorAdapter());
em.setJpaProperties(additionalProperties());
return em;
}
@Bean
public JpaVendorAdapter vendorAdapter(){
return new HibernateJpaVendorAdapter();
}
@Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory emf, DataSource ds) {
JpaTransactionManager jtm = new JpaTransactionManager();
jtm.setEntityManagerFactory(emf);
return jtm;
}
谢谢你的回答。我已经做了你建议的改变，但问题仍然存在。
