Question

我在mvc-dispatcher-servlet.xml中使用spring profile。但是得到错误：

cvc-complex-type.2.4.a: Invalid content was found starting with element 'bean'. One of '{"http://www.springframework.org/schema/beans":beans}' is expected.

我没有在配置文件中添加其他bean，因为我希望在两个配置文件中使用这些bean。需要帮助解决错误。下面是我的XML，错误来自line- bean id =“transactionManager” 类= “org.springframework.orm.hibernate5.HibernateTransactionManager” ＆GT; ：

Answer 1

读取XSD文件时，第一级<bean>...</bean>元素（即transactionManager和后续bean）必须在嵌套的<beans profile="xxx">...</beans>元素之前出现。

这是XSD的片段

<xsd:element name="beans"><xsd:annotation><xsd:documentation>
    ...
    <xsd:complexType>
        <xsd:sequence>
            <xsd:element ref="description" minOccurs="0"/>
            <xsd:choice minOccurs="0" maxOccurs="unbounded">
                <xsd:element ref="import"/>
                <xsd:element ref="alias"/>
                <xsd:element ref="bean"/>
                <xsd:any namespace="##other" processContents="strict" minOccurs="0" maxOccurs="unbounded"/>
            </xsd:choice>
            <xsd:element ref="beans" minOccurs="0" maxOccurs="unbounded"/>
        </xsd:sequence>
        ...

这表示beans元素必须是包含description（在别处定义）的序列，后跟零个或多个元素，可以是import，alias中的任何一个或bean（也以其他顺序在其他地方定义），后跟零个或多个beans元素（递归定义）。
