public class FilterChainDefinitionMapBuilder {
	
	public LinkedHashMap<String,String> buildFilterChainDefinitionMap(){
		LinkedHashMap<String,String> lHMap=new LinkedHashMap<>();
		lHMap.put("/login.jsp", "anon");
		lHMap.put("/shiro/login", "anon");
		lHMap.put("/shiro/logout", "logout");
		lHMap.put("/user.jsp", "roles[user]");
		lHMap.put("/admin.jsp", "roles[admin]");
		lHMap.put("/**","authc");
		return lHMap;
	}
}

	<!-- 配置一个 bean，该 bean 实际上是一个 Map 通过实例工厂方法的方式 -->
    <bean id="filterChainDefinitionBuilder" 
        class="org.lfz.shiro.factory.FilterChainDefinitionMapBuilder"></bean>

    <bean id="filterChainDefinitionMap" 
        factory-bean="filterChainDefinitionBuilder" 
        factory-method="buildFilterChainDefinitionMap"></bean>
