为什么Spring Integration有几种XML模式，应该使用哪一种? [英] Why does Spring Integration have several XML schemas, and which one should I use?
问题描述
要在Spring XML配置文件中使用Spring Integration，我需要声明si命名空间，并提供XML Schema的模式位置:
To use Spring Integration in a Spring XML configuration file, I need to declare the si namespace, and provide the schema location of the XML Schema:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:int="http://www.springframework.org/schema/integration"
xsi:schemaLocation="http://www.springframework.org/schema/integration
http://www.springframework.org/schema/integration/spring-integration.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
但是，根据文档，有两种模式可供选择:
However, according to the docs, there are two schemas to choose from:
从现在开始，用户必须始终声明最新的XML模式 (当前为2.1版).或者，他们可以使用无版本号 模式.通常，最好的选择是使用无版本名称空间， 因为这些将自动使用Spring的最新可用版本 集成.
From now on, users must always declare the latest XML schema (currently version 2.1). Alternatively, they can use the version-less schema. Generally, the best option is to use version-less namespaces, as these will automatically use the latest available version of Spring Integration.

为什么同时存在spring-integration.xsd和spring-integration-2.1.xsd?我检查了两者，后者几乎是前者的三倍.
Why is there both spring-integration.xsd and spring-integration-2.1.xsd? I checked both, and the latter is almost three times as large as the former.
那么，为什么文档会说使用无版本架构更好呢?使用任何一个的后果是什么?还是spring-integration.xsd和spring-integration-2.1.xsd不同的一个错误?
So why do the docs say that it's better to use the version-less schema? What are the consequences of using either one or the other? Or is it just a bug that spring-integration.xsd and spring-integration-2.1.xsd are different?
推荐答案
您不应查看互联网上托管的架构；模式分布在罐子中；在META-INF下还有一个映射文件.
You shouldn't look at the schemas hosted on the internet; the schemas are distributed in the jars; there is also a mapping file under META-INF.
如您所见，在下面，我们总是将无版本架构映射到当前架构；因此，我们建议始终在应用程序配置中使用无版本架构，否则，每次升级时都必须更改文件；例如2.2不能在2.1模式下运行，但是，如果在模式上不使用任何版本，则该框架将使用正确的版本.
As you can see, below, we always map the version-less schema to the current schema; so we recommend always using the version-less schema in your application configs, otherwise you will have to change your files whenever you upgrade; for example 2.2 won't run with a 2.1 schema but, if you use no version on the schema, the framework will take care of using the right one.
Internet上的无版本架构是一个旧的1.0架构；我们需要弄清楚如何改变它，但是由于各种原因，这并不简单，
The version-less schema on the internet is an old 1.0 schema; we need to figure out how we can change that, but it's not simple, for various reasons,
