Question

在尝试设置Spring Security时，我总是遇到这个错误，我仍然不知道如何处理：

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from relative location [security.xml]
Offending resource: ServletContext resource [/WEB-INF/applicationContext.xml]; nested exception is 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/security.xml]

通过对此进行编码，我严格遵循Spring Security documentation。在SO中，我也搜索了类似的问题，但没有一个能解决我的问题。

据我所知，错误主要是由两件事引起的：首先，Spring无法导入security.xml，其次，Spring无法找到其XML架构命名空间的NamespaceHandler。我错过了一些依赖项，或者为什么Spring无法找到其NamespaceHandler？

我将Spring 4.2.0.RELEASE与Spring Security 4.0.2.RELEASE一起使用。

所以，这是我的代码：

的pom.xml

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <version>4.0.2.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
    <version>4.0.2.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>4.0.2.RELEASE</version>
</dependency>

security.xml文件

<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.xsd">

    <http>
        <intercept-url pattern="/**" access="hasRole('ADMIN')" />
        <form-login />
        <logout />
    </http>

    <authentication-manager>
        <authentication-provider>
            <user-service>
                <user name="admin" password="admin" authorities="ROLE_ADMIN" />
            </user-service>
        </authentication-provider>
    </authentication-manager>
</beans:beans>

的web.xml

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:applicationContext.xml
    </param-value>
</context-param>

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

在 applicationContext.xml 中，我只需导入security.xml

<import resource="security.xml" />

您还可以在pom.xml中添加以下内容：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <version>4.0.2.RELEASE</version>
</dependency>

修改

在web.xml中的ContextLoaderListener声明下添加：

<listener> <listener-class>org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:applicationContext.xml </param-value> </context-param>

Spring Security找不到NamespaceHandler
