不能包括对maven的依赖

Question

我有我的pom.xml：

<properties>
    <jdk.version>1.6</jdk.version>
    <spring.version>3.2.8.RELEASE</spring.version>
    <spring.security.version>3.2.3.RELEASE</spring.security.version>
    <jstl.version>1.2</jstl.version>
    <mysql.connector.version>5.1.30</mysql.connector.version>
</properties>

<dependencies>

    <!-- Spring 3 dependencies -->

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>${spring.version}</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>${spring.version}</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>${spring.version}</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <!-- Spring Security -->
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-web</artifactId>
        <version>${spring.security.version}</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-config</artifactId>
        <version>${spring.security.version}</version>
    </dependency>

    <!-- Spring Security JSP Taglib -->
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-taglibs</artifactId>
        <version>${spring.security.version}</version>
    </dependency>

    <!-- jstl for jsp page -->
    <dependency>
        <groupId>jstl</groupId>
        <artifactId>jstl</artifactId>
        <version>${jstl.version}</version>
    </dependency>

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>${mysql.connector.version}</version>
    </dependency>

    <!-- MySQL database driver -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.9</version>
    </dependency>

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
        <scope>provided</scope>
    </dependency>
</dependencies>

我想要包含新的依赖弹簧：

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring</artifactId>
        <version>2.5.6</version>
    </dependency>

但是我的程序出错了：      org.springframework.web.context.ContextLoader.initWebApplicationContext上下文初始化失败     org.springframework.beans.factory.BeanDefinitionStoreException：从ServletContext资源[/WEB-INF/spring-security.xml]解析XML文档的意外异常;     嵌套异常是java.lang.NoSuchMethodError：org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.getLocalName（Lorg / w3c / dom / Node;）Ljava / lang / String;

这是什么意思？

我如何包含我的依赖？也许有版本错误？
