cvc-complex-type.2.4.c：匹配通配符是严格的，但找不到元素“hdp：配置”的声明

Question

Spring Yarn 应用程序出现以下错误。 但是每件事似乎都像 XSD 和所有东西一样放置得很好

org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/hadoop/spring-hadoop.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

这是我的 ApplicationContext.xml。 如果我们删除那些 hdp 标签，没有防火墙问题它工作正常。 还可以使用不同的选项，例如将 xsd 放入 classpath etx。

Answer 1

看起来您缺少类路径中的架构 - XSD 位于 the namespace sub-project 中并被捆绑到 spring-data-hadoop jar 中。

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-hadoop</artifactId>
        <version>2.4.0.RELEASE</version>
    </dependency>

对我来说很好。
