Spring GAE 上的 Boot Rest App 抛出异常无法转换为 javax.persistence.EntityManagerFactory”
Spring Boot Rest App on GAE throws an exception cannot be cast to javax.persistence.EntityManagerFactory"
我的 Spring Boot Restservice 应用 运行 在正常 Spring 应用上下文中正常运行。但是，当我尝试在 Google App Engine 上 运行 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; nested exception is
java.lang.ClassCastException:
org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean$$EnhancerBySpringCGLIB$c05fbf5
cannot be cast to javax.persistence.EntityManagerFactory
这是我的异常的堆栈跟踪：

我今天在将 Spring 应用程序的一部分转换为 Spring 引导应用程序时遇到了同样的问题。问题是 Spring 一直加载默认的 entityManagerFactory bean。
为了使用我的 entityManagerFactory bean，我必须直接 return LocalContainerEntityManagerFactoryBean 的实例，而不是 returning 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;
}
然后在配置的transactionManagerbean中调用entityManagerFactory().getObject():
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(entityManagerFactory().getObject());
return txManager;
}
我的 Spring Boot Restservice 应用 运行 在正常 Spring 应用上下文中正常运行。但是，当我尝试在 Google App Engine 上 运行 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; nested exception is java.lang.ClassCastException: org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean$$EnhancerBySpringCGLIB$c05fbf5 cannot be cast to javax.persistence.EntityManagerFactory
这是我的异常的堆栈跟踪：

为了使用我的 entityManagerFactory bean，我必须直接 return LocalContainerEntityManagerFactoryBean 的实例，而不是 returning 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;
}
然后在配置的transactionManagerbean中调用entityManagerFactory().getObject():
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(entityManagerFactory().getObject());
return txManager;
}
