＆＃34;豆类＆＃34;在服务器启动期间找不到元素

Question

我在服务器启动期间遇到异常。虽然beans元素存在，但它仍然抱怨。不知道我在这里缺少什么。

错误日志：

[/WEB-INF/dispatcher-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 26; columnNumber: 4; cvc-elt.1: Cannot find the declaration of element 'beans'.

调度-servlet.xml中

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

发现了这个问题。

我引用了错误的XSD文档。

应该是：

调度-servlet.xml中

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

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <property name="suffix" value=".jsp" />
    </bean>

</beans>

在bean配置文件中为引用的模式指定版本号根本不是必需的，您可以省略它。事实上，你应该一直省略它。 Spring自动选择项目依赖项（jar）中可用的最高版本。此外，随着项目的发展和Spring版本的更新，从而降低了可维护性。

<?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:context="http://www.springframework.org/schema/context"
  xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">

  <!-- Other bean definitions-->

</beans>
