java - 无法读取架构文档 'http://www.springframework.org/schema/beans/spring- beans-4.0.xsd'？

Question

3 月 2 日，当我使用 eclipse 在自己的电脑上创建项目时，没有出现任何问题，但是当我将 eclipse 从电脑移动到桌面时，我在 security-config.xml 上收到一条错误消息:

错误消息:

Multiple annotations found at this line:
- cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'security:http'.
- Start tag of element <security:http>
- schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/security/spring-
 security.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>.

我的 security-config.xml 文件是:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </security:authentication-manager>

    <bean id="daoAuthenticationProvider" class="org.springframework.security.authentication.dao.DaoAuthenticationProvider">
        <property name="userDetailsService" ref="userServices" />
        <property name="hideUserNotFoundExceptions" value="false" />
    </bean>

    <bean id="authenticationManager" class="org.springframework.security.authentication.ProviderManager">
        <constructor-arg>
            <ref bean="daoAuthenticationProvider" />
        </constructor-arg>
    </bean>

</beans>

有关我的笔记本电脑的更多详细信息，它运行良好

Answer 1

查看http://www.springframework.org/schema/security/

您可能只需要添加您正在使用的 Spring Security 的版本号。也许您的笔记本电脑缓存了旧版本，他们从网站上删除了无版本的版本。

这个应该可以工作: http://www.springframework.org/schema/security/spring-security-4.1.xsd
