我有一个 JUnit 测试来启动我的 spring boot appcliation (Application.java)。
@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class AppclaitionTest {
@Test
public void contextLoads(){
Application.main(new String[]{});
}
}
如果我运行 JUnit 测试，应用程序成功启动，但无法通过 url 访问
应用程序日志：

当我尝试通过 url 访问应用程序时 'http://localhost:8080/进程 http://localhost:8080/process'，它说无法访问站点。
你为什么要做这样的事？这应该是一个单元测试，测试流程应如下：
启动应用程序 -> 调用控制器端点 -> 断言该页面上存在特定文本/元素 -> 关闭应用程序。
启动应用程序：@RunWith(SpringRunner.class)为您执行此操作，无需手动启动。
关闭应用程序：在测试类结束时，Spring boot 会为您执行此操作（这就是您无法在浏览器中访问您的应用程序的原因）
