mybatis项目单元测试,junit报错:找不到测试类

刚开始学mybatis,Junit运行出现了找不到测试类的情况 这是报错信息: ![图片说明](https://img-ask.csdn.net/upload/201911/21/1574303586_534941.png) 这个是代码: ![图片说明](https://img-ask.csdn.net/upload/201911/21/1574303753_113211.png) ![图片说明](https://img-ask.csdn.net/upload/201911/21/1574303786_311038.png) ![图片说明](https://img-ask.csdn.net/upload/201911/21/1574303829_922250.png) 还有项目的一些包: ![图片说明](https://img-ask.csdn.net/upload/201911/21/1574303879_11919.png) 之前也试过在编译器你改默认的构建,但是没什么效果,也看了jdk1.8和mybatis3应该不冲突。求问大佬们是什么问题?

关于junit对DAO类中数据库操作的测试

头一次用JUNIT,有些不明白的地方,请各位大侠多多指教 我是通过JDBCTemplate来连接数据库的,通过JUNIT对UserDAOImpl中的getUserById()进行测试。该方法如下: public UserInfo getUserById(String userId) { String sql = "select * from userinfo where userid='" + userId + "'"; System.out.println(sql); UserInfo userInfo = (UserInfo) jt.queryForObject(sql, new UserMapper()); return userInfo; } 我编写的测试用例如下: private UserInfo user; private UserDAO userDAO; @Test public void testGetUserById() { user = userDAO.getUserById("admin"); assertEquals("admin",user.getUserId()); } 数据库的配置是在applicationContext.xml中配置的,通过网页调取都很顺利,但测试用例报告java.lang.NullPointerException at css.user.dao.UserDAOImplTest.testGetUserById(UserDAOImplTest.java:49) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:73) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:46) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:180) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:41) at org.junit.runners.ParentRunner$1.evaluate(ParentRunner.java:173) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.junit.runners.ParentRunner.run(ParentRunner.java:220) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:46) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) 求指点迷津,谢谢!
