SpringBoot整合Junit
添加Junit的起步依赖:如果是使用idea快速创建SpringBoot项目,那么pom文件中已经有了测试的起步依赖
<!--测试的起步依赖--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency>
编写测试类:
@RunWith(SpringRunner.class) @SpringBootTest(classes = MySpringBootApplication.class) public class MapperTest { @Autowired private UserMapper userMapper; @Test public void test() { List<User> users = userMapper.queryUserList(); System.out.println(users); } }
SpringRunner继承自SpringJUnit4ClassRunner,使用哪一个Spring提供的测试引擎都可以
public final class SpringRunner extends SpringJUnit4ClassRunner
@SpringBootTest的属性指定的是引导类的字节码对象
