如何在spring安全xml配置中避免重复

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:security="http://www.springframework.org/schema/security"
       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">

    <security:http>
        <security:intercept-url pattern="/public/**" access="permitAll" />
        <security:intercept-url pattern="/admin/**" access="hasRole('ROLE_ADMIN')" />
        <security:intercept-url pattern="/user/**" access="hasRole('ROLE_USER')" />
        <security:intercept-url pattern="/api/**" access="hasAnyRole('ROLE_ADMIN', 'ROLE_USER')" />
        <security:form-login />
        <security:access-denied-handler error-page="/access-denied" />
    </security:http>

    <!-- 其他配置 -->
