Question

我在java 1.7上使用spring boot 1.4.1。我有一个带有一个get端点的样本控制器＆＃34; show＆＃34;

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = SomeController.class)
public class SomeControllerTest {

    @Autowired
    MockMvc mockMvc;

    @Test
    public void showPage() throws Exception {
        mockMvc
                .perform(get("/show"))
                .andExpect(content().string(containsString("Some Result")));
    }

 }

以下是我尝试执行测试时遇到的错误。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mockMvcWebClientBuilder' defined in class path resource [org/springframework/boot/test/autoconfigure/web/servlet/MockMvcWebClientAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.test.web.servlet.htmlunit.MockMvcWebClientBuilder]: Factory method 'mockMvcWebClientBuilder' threw exception; nested exception is java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=org/eclipse/jetty/websocket/api/Session, offset=6

仔细看看原因是

   org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.test.web.servlet.htmlunit.MockMvcWebClientBuilder]: Factory method 'mockMvcWebClientBuilder' threw exception; nested exception is java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=org/eclipse/jetty/websocket/api/Session, offset=6

有人可以告诉我是否可以使用java 1.7进行测试？

Answer 1

Spring Boot 1.4.1包含Jetty 9.3（see spring-boot-dependencies pom.xml）

Their documentation说Jetty 9.3需要Java 8+。您应该通过重新定义pom中的属性来替换Jetty 9.2：

<properties>
    <jetty.version>9.2.19.v20160908</jetty.version>
</properties>

这恰好是Spring的确切推荐（in their documentation）：

将Jetty 9.2与Maven一起使用

如果您使用的是初学者和家长，您可以添加Jetty 启动并覆盖jetty.version属性：

<properties>
    <jetty.version>9.2.17.v20160517</jetty.version>
</properties>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jetty</artifactId>
    </dependency>
</dependencies>

我们可以在java 1.7中使用spring boot 1.4.1测试框架吗？
