cvc-elt.1：找不到元素“beans”的声明

java spring spring-security

2022-09-03 13:42:54

我正在尝试获取一个bean对象来验证Spring Security的用户登录功能：

    ApplicationContext context = new ClassPathXmlApplicationContext(
            "com/humandevice/drive/fx/util/applicationContext.xml");
    authenticationManager = (AuthenticationManager) context
            .getBean("authenticationManager");

我的在下面：applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/security"
xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/security
       http://www.springframework.org/schema/security/spring-security-3.2.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd"
xmlns:context="http://www.springframework.org/schema/context">
<context:component-scan base-package="com.humandevice.drive.fx">
    <context:include-filter type="regex"
        expression="com.humandevice.drive.fx.*" />
</context:component-scan>
<bean id="LoginController" alias="loginController" class="controller.LoginController">
    <property name="authenticationManager" ref="authenticationManager" />
    <property name="applicationContext" ref="applicationContext" />
</bean>
<bean id="applicationContext" alias="applicationContext"
    class="org.springframework.context.ApplicationContext;">
</bean>
<authentication-manager alias="authenticationManager">
    <authentication-provider user-service-ref="userService">
        <password-encoder ref="bCryptPasswordEncoder" />
    </authentication-provider>
</authentication-manager>
 </beans>

但我得到这个例外：

Caused by: org.xml.sax.SAXParseException; lineNumber: 9; columnNumber: 64; cvc-elt.1: Cannot find the declaration of element 'beans'.

我很难理解这个问题。

更新

我对我的XML进行了一些更改，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
    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"
    xmlns:task="http://www.springframework.org/schema/task"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.2.xsd">

    <import resource="/context-service.xml" />
    <import resource="/context-repository.xml" />

    <context:component-scan base-package="com.humandevice.drive.fx"></context:component-scan>

    <authentication-manager>
        <authentication-provider user-service-ref="com.humandevice.drive.service.user.IUserService">
            <password-encoder ref="bCryptPasswordEncoder" />
        </authentication-provider>
    </authentication-manager>
</beans:beans>

我现在收到此异常：

lineNumber: 11; columnNumber: 44; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'import'.

您的默认命名空间是，并且您配置了这意味着您必须将前缀添加到所有标记表单中，以便您的 XML 应如下所示。http://www.springframework.org/schema/securityxmlns:beans="http://www.springframework.org/schema/beans"beans:http://www.springframework.org/schema/beans

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

    </context:component-scan>
    <beans:bean id="LoginController" alias="loginController" class="controller.LoginController">

        </authentication-provider>
    </authentication-manager>
</beans:beans>
