我会用TestContainers测试一个spring boot应用程序，但我不明白正确的方法。
这是我的控制者：
@RestController
@RequestMapping(value = "snip")
public class Controller {
@RequestMapping(method = RequestMethod.GET, path = "/hello", produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<String> hello (){
return new ResponseEntity<String>("Hello World!!", HttpStatus.OK);
}
}
这是我的测试课程：
public class ControllerTest {
@Rule
public GenericContainer container = new GenericContainer(
new ImageFromDockerfile()
.withFileFromFile("target/springboot-testcontainers-snip-1.0-SNAPSHOT.jar", new File("target/springboot-testcontainers-snip-1.0-SNAPSHOT.jar"))
.withFileFromPath("./Dockerfile", new File("./Dockerfile").toPath())
)
.withExposedPorts(8080);
@Before
public void setup() {
RestAssured.baseURI = "http://" + container.getContainerIpAddress() + ":" + container.getMappedPort(8080);
}
@Test
public void testHello() {
Response response = get("/snip/hello");
assertEquals(response.statusCode(), 200);
}
}
Dockerfile：
FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD target/springboot-testcontainers-snip-1.0-SNAPSHOT.jar app-snip.jar
RUN sh -c 'touch /app-snip.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "java","-Djava.security.egd=file:/dev/./urandom","-jar","/app-snip.jar" ]

最后是错误：

从日志中可以看出＆＃39; spring boot＆＃39;是正确的， 问题在哪里？
我使用的是Mac（sierra 10.13.1） Docker版本17.09.0-ce，构建afdb6d4
提前致谢！
