如何在Spring XML文件中使用DOCTYPE [英] How to use DOCTYPE in Spring XML file

问题描述

大多数时候，我们在春季没有声明 DOCTYPE 。
但我想在XML上下文文件中声明DOCTYPE，以便可以在XML文件中使用 ENTITY 。

Most of the time we do not declare DOCTYPE in Spring. But I want to declare a DOCTYPE in my XML context file so that I can use ENTITY in my xml file.

例如：

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"
                  "http://www.springframework.org/dtd/spring-beans-2.0.dtd"
    [<!ENTITY % crmHome SYSTEM "crm-home.dtd"> %crmHome;]
>

这会产生许多错误，例如...

This gives many errors like...

 - Attribute "xmlns" must be declared for element type "beans".

 - Attribute "xmlns:xsi" must be declared for element type "beans".

    etc.....

实现此目标的方法是什么？

What is the way to achieve this?
