Spring Boot测试无法注入TestRestTemplate和MockMvc

Question

我使用的是spring boot1.4.0.release。我正在为我的controller类编写测试。我得到以下例外情况。

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.concur.cognos.authentication.service.ServiceControllerITTest': Unsatisfied dependency expressed through field 'restTemplate': No qualifying bean of type [org.springframework.boot.test.web.client.TestRestTemplate] found for dependency [org.springframework.boot.test.web.client.TestRestTemplate]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.boot.test.web.client.TestRestTemplate] found for dependency [org.springframework.boot.test.web.client.TestRestTemplate]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

这是我的测试类

public class ServiceControllerITTest extends ApplicationTests {

    @Autowired
    private TestRestTemplate restTemplate;

    @Autowired
    private MockMvc mvc;

    @Test
    public void exampleTest() throws Exception {
         // test
    }
}

applicationtests.java

@RunWith(SpringRunner.class)
@SpringBootTest
@WebAppConfiguration
//@DirtiesContext
public class ApplicationTests {

    @Autowired
    Environment env;

    @Test
    public void contextLoads() {

    }

}

TestRestTemplate只有在@SpringBootTest配置了WebEnvironment（这意味着它启动web容器并侦听HTTP请求）时，才会自动配置TestRestTemplate。例如：

@SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT)
