springboot框架

[昨天刚刚过去]

@RunWith(SpringRunner.class) @SpringBootTest public class UserMapperTests { @Autowired UserMapper mapper; @Test public void addnew() { User user=new User(); user.setUsername("roo"); user.setPassword("1234"); Integer row=mapper.addnew(user); System.err.println(row); } @Test public void findByUsername() { User user=mapper.findByUsername("root"); System.err.println(user); } } 我想测试这个，但是报错了！ org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'cn.tedu.stora.mapper.UserMapperTests': Unsatisfied dependency expressed through field 'mapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'cn.tedu.stora.mapper.UserMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 什么原因？求大神告知
