1添加test依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency>
2创建SbootTest测试类
4在测试类注入测试对象
@RunWith(SpringRunner.class) @SpringBootTest(classes = HelloApplication.class) public class SbootTest { @Autowired private UserMapper userMapper; @Test public void getUserList(){ List<MUser> userList=userMapper.getUserList(); for (MUser user:userList){ System.out.println(user); } } }
