大体是这样子的思路：Forum 1：n Course Course 1：nTopic Topic 1：n Reply 一张的，我成功过。所以我想引入两张的，然后JUnit 测试数据竟然过不了。 2014-12-23 18:31:03,550 ERROR [org.springframework.test.context.TestContextManager.prepareTestInstance(TestContextManager.java:324)] – Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@2dd4708d] to prepare test instance [cn.edu.fjnu.java1.cdio2.yplan.service.ForumServiceTest@5629507c] |

容器貌似都没加载成功，实体配置有问题吧？贴出代码看看

现在的一个问题是，我现在用junit测试，前面两张 forumTest 和courseTest测试都成功通过，并且在mysql建起表有数据，然后topicTest 能够建表，但是空数据。并且报错： org.springframework.dao.InvalidDataAccessApiUsageException: object references an unsaved transient instance - save the transient instance before flushing: cn.edu.fjnu.java1.cdio2.yplan.domain.Course; nested exception is org.hibernate.TransientObjectException: object references an unsaved transient instance -

save the transient instance before flushing: cn.edu.fjnu.java1.cdio2.yplan.domain.Course
把主控端的cascade 属性修改为”save-update”试试 |

问题已经解决了，太大意了。 |
