spring接入swagger后单元测试报错

spring:4.1.1.RELEASE

swagger:2.4.0

如下所示错误：

查阅文档，发现https://github.com/springfox/springfox/issues/1099这边有解决办法

就是要测试用例上面加@WebAppConfiguration注解，如下所示：

 

 

 

@RunWith(SpringJUnit4ClassRunner.class)

@WebAppConfiguration

@ContextConfiguration(locations = {"classpath:applicationContext.xml"})

public class TransactionServiceTest {

    @Autowired

    private TransactionService transactionService;

}

 

但是运行测试用例时依然报错，如下所示：

解决方法见：http://stackoverflow.com/questions/21561432/failed-to-load-applicationcontext-during-spring-unit-test

 

只需要把servlet的版本升级到3.X就可以了

至此，问题解决
