GAE上的Spring Boot Rest应用程序抛出异常无法转换为javax.persistence.EntityManagerFactory“
[英]Spring Boot Rest App on GAE throws an exception cannot be cast to javax.persistence.EntityManagerFactory"
问题描述
My Spring Boot Restservice App is running just fine in normal Spring App Context. 
我的Spring Boot Restservice App在正常的Spring App Context中正常运行。 But when I try to run it on Google App Engine the following Exception is thrown: 但是当我尝试在Google App Engine上运行它时会抛出以下异常：
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.transaction.PlatformTransactionManager]: Factory method 'transactionManager' threw exception;
here is the stacktrace of my exception: 这是我的异常的堆栈跟踪：

I was having the same problem today converting a part of a Spring application to a Spring Boot application. 今天我遇到了同样的问题，将Spring应用程序的一部分转换为Spring Boot应用程序。 The problem was that Spring kept loading a default entityManagerFactory bean. 问题是Spring继续加载一个默认的entityManagerFactory bean。
In order to use my entityManagerFactory bean I had to return the instance of LocalContainerEntityManagerFactoryBean directly, instead of returning LocalContainerEntityManagerFactoryBean 's getObject() : 为了使用我entityManagerFactory豆我不得不返回实例LocalContainerEntityManagerFactoryBean直接而不是返回， LocalContainerEntityManagerFactoryBean的getObject()
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl(true);
vendorAdapter.setShowSql(true);
vendorAdapter.setDatabasePlatform("org.hibernate.dialect.MySQLDialect");
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(vendorAdapter);
factory.setJpaDialect(new HibernateJpaDialect());
factory.setPackagesToScan("com.pekam");
factory.setDataSource(MyDataSource());
factory.afterPropertiesSet();
return factory;
}
and then in the configuration of the transactionManager bean call entityManagerFactory().getObject() : 然后在transactionManager bean的配置中调用entityManagerFactory().getObject() ：
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(entityManagerFactory().getObject());
return txManager;
}
