我正在使用Spring Maven Hibernate并希望在PostgreSQL环境中运行测试.

添加适当的依赖项并更改我的xml文件后,在cmd中运行mvn clean install时出现以下错误：

Coult not open JPA EntityManager for transaction; nested exception is javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Cannot open connection

测试的输出日志类似于：

testFlush(com.mms.pone.portal.domain.AccountAllocationIntegrationTest)  Time elapsed: 15.432 sec  <<< ERROR!
