spring junit

spring提供了一套单元测试，免了我们配置数据库。还有spring的一套配置。

import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import org.springframework.test.context.transaction.TransactionConfiguration;import org.springframework.transaction.annotation.Transactional;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = { "classpath*:**/applicationContext-*.xml" })@TransactionConfiguration(transactionManager="transactionManager", defaultRollback=false)@Transactionalpublic abstract class BasicTestcase extends AbstractTransactionalJUnit4SpringContextTests{}

以后我们只要继承这个方法就可以单元测试了
