解决：

创建两个 TransactionManager

 

@Bean(name=”transactionManager”)
@Primary
public PlatformTransactionManager defaultTransactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setPersistenceUnitName(“default22″);
return txManager;
}
@Bean(name=”crmTx”)
public PlatformTransactionManager crmTransactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setPersistenceUnitName(“crm”);
return txManager;
}
