配置Spring-Security报错，找不到元素 'b:beans' 的声明

Spring新手，现在想在SpringMVC的基础上使用Spring Security框架。但Spring Security配置报错，困扰了很久。先上代码

 <?xml version=""1.0"" encoding=""UTF-8""?><b:beans xmlns=""http://www.springframework.org/schema/security""         xmlns:b=""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-3.1.xsd"">

报错

 org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 9 in XML document from class path resource [config/spring-security.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 9; columnNumber: 99; cvc-elt.1: 找不到元素 'b:beans' 的声明。

尝试网上的方法，加入

 <!DOCTYPE b:beans PUBLIC ""-//SPRING//DTD BEAN//EN"" ""http://www.springframework.org/dtd/spring-beans.dtd"">

则报错

 org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 9 in XML document from class path resource [config/spring-security.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 9; columnNumber: 99; 必须声明元素类型 ""b:beans""。

请指教

解决方案

Spring的配置文件找不到元素 'beans' 的声明
spring配置报错
Spring配置报错
