获取 org.xml.sax.SAXParseException 启动 Spring MVC 应用程序

Question

我在启动我的 Spring MVC 应用程序时收到 org.xml.sax.SAXParseException。我一直在疯狂地谷歌搜索，试图弄清楚这一点。这就是我在 Tomcat 8.0.30 中得到的。

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 11 in XML document from ServletContext resource [/WEB-INF/applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 11; columnNumber: 72; Document root element "beans", must match DOCTYPE root "xml".

plus a whole bunch more lines

这是我的 applicationContext.xml。第 11 行以 spring-mvc-4.3.xsd 结尾。

<?xml version="1.0" encoding="UTF-8"?>

    <mvc:view-controller path="/" view-name="home" />

    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="username" value="ghscom_root" />
        <property name="password" value="GHSMatadors1986" />
    </bean>
</beans>

这是我用于 Maven 的 pom.xml。我也许应该指出，我是 Maven 的相对新手，所以如果问题出在这就是原因。

Answer 1

<!DOCTYPE xml>
<beans xmlns="http://www.springframework.org/schema/beans"
    ....

使用<!DOCTYPE xml>，您告诉XML 解析器根元素将是<xml>，而不是<beans>。

完全删除 DOCTYPE 声明，即用于旧式 DTD 验证并且您正在使用模式。

如果您仍在使用 DTD 验证（我认为它已被弃用），则 DOCTYPE 将类似于

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"
    "http://www.springframework.org/dtd/spring-beans-2.0.dtd">

但这适用于 Spring 2.0，它是古老的。
