Question

我是XML Parsing和DTD的新手。我试图创建一个简单的SpringBean程序并使用Spring.xml实例化一个类（Triangle.java）。

我的DrawingApp.java看起来像：

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.FileSystemResource;

public class DrawingApp {

    /**
     * @param args
     */
    public static void main(String[] args) {
BeanFactory factory = new XmlBeanFactory(new FileSystemResource("Spring.xml"));
    Triangle triangle = (Triangle) context.getBean("triangle");
    triangle.draw();

我的Spring.xml就像：

    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<bean>
<bean id="triangle" class="org.kumarjivi.Triangle" />
</bean>

我用Google搜索并搜索了StackOverFlow上相同问题的早期答案，他们说出了禁用DTD验证（我认为从DOCTYPE行中给出的url验证DTD。我能够访问url中指定的dtd）通过网络浏览器）。但我不知道该怎么做。

我得到的例外是：

Answer 1

http://www.w3.org/TR/html4/loose.dtd包含

行

<!ENTITY % HTML.Version "-//W3C//DTD HTML 4.01 Transitional//EN"
  -- Typical usage:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    ... 43 lines ...

-->

使用SGML的一个不起眼的功能来包含冗长的注释。对于XML解析器，看起来好像是尾随>。

这就是导致此错误消息的原因，但是 -

从<!DOCTYPE HTML...>删除spring.xml行。 Spring XML文件不是HTML，不应声称是。 HTML！= XML。

Answer 2

这适用于我最新的Spring Framework v.4.2.1

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">

实体“HTML.Version”的声明必须以“＆gt;”结尾
