# 集成端点
## 端点快速参考表
正如前面几节中所讨论的， Spring 集成提供了许多端点，这些端点用于与外部系统、文件系统和其他系统进行接口。
对于透明的依赖管理 Spring，集成提供了要导入到 Maven 配置中的材料清单 POM:
```
org.springframework.integration
spring-integration-bom
5.5.9
pom
import
```
总结一下：
* 入站通道适配器用于单向集成，以将数据带入消息传递应用程序。
* 出站通道适配器用于单向集成，以将数据发送到消息传递应用程序之外。
* 入站网关用于双向集成流，其中其他一些系统调用消息传递应用程序并接收答复。
* 出站网关用于双向集成流，其中消息传递应用程序调用某些外部服务或实体并期望得到结果。
下表总结了各种端点，并提供了与相应章节的快速链接。

此外，如[核心消息传递](./core.html#spring-integration-core-messaging)中所讨论的， Spring 集成提供了与普通旧 Java 对象接口的端点。正如[通道适配器](./channel-adapter.html#channel-adapter)中所讨论的，``元素允许你轮询 Java 方法中的数据。``元素允许你将数据发送到`void`方法。正如[消息传递网关](./gateway.html#gateway)中所讨论的，``元素允许任何 Java 程序调用消息流。所有这些都可以工作，而不需要对 Spring 集成有任何源码级依赖。在此上下文中，相当于出站网关的方法是使用服务激活器（参见[服务激活器](./service-activator.html#service-activator)）来调用返回某种类型的`Object`的方法。
从版本`5.2.2`开始，所有入站网关都可以配置`errorOnTimeout`布尔标志，以便在下游流在回复超时期间不返回回复时抛出`MessageTimeoutException`。在线程将控制权返回到网关之前，计时器不会启动，因此通常只有在下游流是异步的或者由于某些处理程序返回`null`而停止时，计时器才有用，例如[filter](./filter.html#filter)。这样的异常可以在`errorChannel`流上进行处理，例如，为请求客户端生成补偿应答。
