任何想法是什么可能导致这种情况？

无法找到 Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/security]

org.springframework.web.context.ContextLoader initWebApplicationContext: Context initialization failed
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/security]
Offending resource: ServletContext resource [/WEB-INF/applicationContext.xml]

这是我的应用程序Context.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/security
        http://www.springframework.org/schema/security/spring-security-3.0.xsd">
...
</beans:beans>

在我的pom中.xml我有：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>      
    <version>3.0.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-openid</artifactId>
    <version>3.0.1.RELEASE</version>
</dependency>

答案 1

我需要添加一个额外的 Maven 依赖项：

    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-config</artifactId>
        <version>3.0.1.RELEASE</version>
    </dependency>

答案 2

我在尝试部署应用程序时收到相同的错误消息。在Spring中，安全配置xml可以与appplicationContext.xml，通常是appplicationContext-security.xml web-INF文件夹中。要应用的更改适用于 Web.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/applicationContext.xml
        /WEB-INF/applicationContext-security.xml
    </param-value>
</context-param>

应用程序Context.xml将如下所示：

<?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-3.0.xsd
                        http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd">

    <http auto-config='true'>
        <intercept-url pattern="/login.jsp" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
        <intercept-url pattern="/**" access="ROLE_USER" />
        <form-login login-page='login.jsp'/>
    </http>

</beans:beans>

即使进行这些更改，命名空间错误仍将存在。要解决此问题，请将以下 jar 文件添加到 WEB-INF/lib，然后添加到库中：

弹簧-安全-acl-3.1.0.M2.jar
弹簧-安全-配置-3.1.0.M2.jar
弹簧-安全-核心-3.1.0.M2.jar
spring-security-taglibs-3.1.0.M2.jar
spring-security-web-3.1.0.M2.jar
