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

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

我的 applicationContext.xml 如下:

<?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>

但我得到了这个异常(exception):

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。

我已经对我的 XML 进行了一些更改:

<?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>

我现在收到这个异常:

行号:11；列号:44； cvc-complex-type.2.4.c:匹配通配符是严格的，但找不到元素'import'的声明。

最佳答案

您的默认命名空间是 http://www.springframework.org/schema/security 并且您配置了 xmlns:beans="http://www.springframework.org/schema/beans"这意味着您必须将前缀 beans: 添加到所有标签形式 http://www.springframework.org/schema/beans 以便您的XML 应如下所示。

<?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"
       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>
    <beans:bean id="LoginController" alias="loginController" class="controller.LoginController">

        <beans:property name="applicationContext" ref="applicationContext" />
    </beans:bean>
    <beans:bean id="applicationContext" alias="applicationContext"
          class="org.springframework.context.ApplicationContext;">
    </beans:bean>
    <authentication-manager alias="authenticationManager">
        <authentication-provider user-service-ref="userService">
            <password-encoder ref="bCryptPasswordEncoder" />
        </authentication-provider>
    </authentication-manager>
</beans:beans>
