使用junit测试springMVC项目提示ServletContext找不到定义错误

原文链接：https://blog.csdn.net/liu_gan/article/details/78400627

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations = {"classpath:dispatcher-servlet.xml"})
public class UserApplicationTest {
    private static final Log logger = LogFactory.getLog(UserApplicationTest.class);
    @Autowired
    private UserAccessDao userAccessDao;

    @Test
    public void test() {
        UserAccessEntity userAccess = userAccessDao.selectByPrimaryKey(1L);
        logger.info("userAccess ={}", JSON.toJSONString(userAccess));
    }

}

跑test报错如下：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [javax.servlet.ServletContext] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: 

解决：

其实提示很清楚就是找不到注入javax.servlet.ServletContext 的实例，明显就是没有web容器环境

解决办法就是配置web容器配置

为类添加注解 @WebAppConfiguration 即可。全部如下：

 

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations = {"classpath:dispatcher-servlet.xml"})
public class UserApplicationTest {
    private static final Log logger = LogFactory.getLog(UserApplicationTest.class);
    @Autowired
    private UserAccessDao userAccessDao;

    @Test
    public void test() {
        UserAccessEntity userAccess = userAccessDao.selectByPrimaryKey(1L);
        logger.info("userAccess ={}", JSON.toJSONString(userAccess));
    }

}
