错误：cvc-elt.1.a：找不到元素“beans”的声明

Question

添加此代码时，出现此错误，我尝试将 beans:beans 添加到标签中，但随后出现相同的错误，请帮我解决这个问题

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

    <bean id="testBean"
        class="alishev.spring.demo.TestBean">
        <constructor-arg value="Neil"/>
    </bean>

</beans>

Answer 1

您拥有

xmlns:beans="http://www.springframework.org/schema/beans"

，这意味着您需要为该命名空间中的所有标签添加前缀

beans:

。

从

:beans

中删除

xmlns:beans="http://www.springframework.org/schema/beans"

，这样您的 XML 应如下所示

<?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">

    <bean id="testBean"
        class="alishev.spring.demo.TestBean">
        <constructor-arg value="Neil"/>
    </bean>

</beans>
