我正在寻找yUML的替代品,最好是开源的.当然yUML很棒,我真的很喜欢它,但我希望能够扩展它.

我也对同一方向的其他服务感兴趣(图生成),但我不是在寻找任何(UML)桌面工具.

如何模拟spring rabbitmq/amqp,以便在尝试自动创建交换/队列时在Spring Boot Test期间不会失败？

鉴于我有一个简单的RabbitListener,将导致队列和交换自动创建如下:

@Component
@RabbitListener(bindings = {
        @QueueBinding(
                value = @Queue(value = "myqueue", autoDelete = "true"), 
                exchange = @Exchange(value = "myexchange", autoDelete = "true", type = "direct"), 
                key = "mykey")}
)
@RabbitListenerCondition
public class EventHandler {
    @RabbitHandler
    public void onEvent(Event event) {
      ...
    }   
}

在简单的Spring Boot Test中,如下所示:

@ActiveProfiles("test")
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT, classes = { Application.class })

    @Autowired
    private ApplicationContext applicationContext;

    @Test
    public void test() {
        assertNotNull(applicationContext);
    }

}

它将失败:

16:22:16.527 [SimpleAsyncTaskExecutor-1] ERROR o.s.a.r.l.SimpleMessageListenerContainer - …

我在Jenkins工作流插件unarchive的教程中看到了多种用法.但我无法找到有关其语法和选项的任何文档.

我试图遵循本文[1]在Spring MvcMock测试中模拟安全性。

我要测试的REST服务如下所示：

@RequestMapping(value = "/something/{id}", method = RequestMethod.DELETE)
public ResponseEntity<Void> deleteXXX(@ActiveUser AppUser user, @PathVariable(value = "id") Long id) {
  ...
}

其中@ActiveUser是的自定义实现/扩展@AuthenticationPrincipal和，AppUser是自定义UserDetails实现。

在测试中，我这样做：

mockMvc.perform(delete("/something/{i}", "123").with(user(new AppUser(...))));

我还添加了一些TestExecutionLIsteners：

@TestExecutionListeners(listeners = { ServletTestExecutionListener.class, DependencyInjectionTestExecutionListener.class, DirtiesContextTestExecutionListener.class, TransactionalTestExecutionListener.class, WithSecurityContextTestExecutionListener.class })

```

但是它失败了：

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [com.corp.AppUser]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.corp.AppUser.<init>()
at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:973)
at org.springframework.web.servlet.FrameworkServlet.doDelete(FrameworkServlet.java:885)

可以，因为AppUser它没有默认的构造函数，但是框架实际上不应该创建用户，而是使用我传递给测试的那个。

为了在运行时解决此问题，我必须将 …

我尝试通过AppStore安装XCode,但它失败并显示以下消息:

We could not complete your purchase
Xcode is already installed on this computer. Choose Software Update from the Apple menu to check for available updates.

这可能是由之前的一次尝试通过从开发人员中心下载 - 但由于那次失败,我尝试使用现在也失败的AppStore ...

如何从失败的XCode安装中真正删除所有以重新启动AppStore？

顺便说一句.我已经这样做了:

sudo /Developer/Library/uninstall-devtools --mode=all

非常感谢!

之前也曾提出过类似的问题，但我找不到确切的答案...

在本UserData节中，我有一个需要访问其自己的公共IP的EC2实例的定义：

  "MyEC2Instance": {
    "Type": "AWS::EC2::Instance",
    "Properties": {
      "SubnetId": {
        "Fn::ImportValue": {
          "Fn::Sub": "${NetworkStackName}-SubnetID"
        }
      },
      "ImageId": "ami-xxxx",
      "InstanceType": { "Ref": "InstanceTypeParameter" },
      "IamInstanceProfile": { "Ref": "MasterInstanceProfile" },
      "UserData": {
        "Fn::Base64": {
          "Fn::Join": [
            "",
            [
              "#!/bin/bash -v\n",
              " PUBLIC_IP=",
              {
                "Fn::GetAtt": ["MyEC2Instance", "PublicIp"]
              },
              " /usr/local/bin/docker-compose -f /docker-compose.yml up -d\n"
            ]
          ]
        }
      }
    }

通常，通过可以很容易地访问它"Fn::GetAtt": ["MyEC2Instance", "PublicIp"]，但是在这种情况下，这会引发“循环依赖项错误”-确保这样做确实有意义，但是我该如何解决呢？

我们有一个依赖项 (JAR)，它包含一个引用其Class-Path条目中其他 JAR 的清单文件。应用程序不需要这些引用的其他 JAR，因此不会添加为依赖项。

当应用程序启动时，tomcat 尝试解析该类路径条目，最终会在日志中出现大量错误。喜欢：
