Spring整合Junit单元测试

首先pom.xml加入如下依赖

<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>5.1.5.RELEASE</version>
<scope>test</scope>
</dependency>

创建testDemo

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "/spring-mybatis.xml")
public class UserServiceImplTest {
@Autowired
private UserMapper userMapper;
@Test
public void testFindAllUsers(){
Assert.assertEquals(1,userMapper.findAllUsers().size());
}
}

注意版本Spring-test版本尽量与Spring版本保持一致
