无法在Eclipse - SAXParseException中加载bean XSD
无法在Eclipse - SAXParseException中加载bean XSD
提问于 2016-09-01 19:29:56
我想在Eclipse中运行一个简单的Hello World程序(使用Maven和Spring集成)。在beans.xml中，我有以下内容：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="person" class="spring.tutorial.Person"></bean>
</beans>在App.java中，我使用ApplicationContext来实例化person bean。不幸的是，我得到了这个错误：

at spring.tutorial.App.main(App.java:10) 我猜这意味着Eclipse找不到第5行的"http://www.springframework.org/schema/beans/spring-beans.xsd“文件，我已经在浏览器中检查过了，XSD存在。
如果我尝试使用spring-beans.xsd的特定版本，则没有任何变化。我确信我也有网络连接。

从错误堆栈跟踪来看，程序似乎正在执行DTD验证，而不是XSD验证。
这将是一些需要研究的东西，以确保XSD验证按照您的意图执行。
如果使用DTD验证，文档将看起来像这样，但这是较旧的方法：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="person" class="spring.tutorial.Person"></bean>
