问题描述

我想在本地缓存 LDAP 用户数据以加快查询速度.Spring LDAP 是否提供这样的功能?我该怎么做?

I want to cache LDAP user data locally to allow faster queries. Do the Spring LDAP offers such a functionality? How can I do this?

我正在使用 Spring Security 3.1 和 Spring LDAP 1.3.1 进行身份验证和授权.如果存在的话，使用内置机制为 LDAP 提供缓存会很好..

I am using Spring Security 3.1 and Spring LDAP 1.3.1 for authentication and authorization. It would be nice to have a cache for LDAP using built-in mechanism if exists..

applicationContext-ldap.xml:

<?xml  version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <jee:jndi-lookup id="ldapPassword" jndi-name="appName/ldapPassword" expected-type="java.lang.String" />

    <!-- for authentication and search purpose -->

    </bean>

    <bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">

    </bean>

    <!-- for pagination search purpose  -->
    <bean id="dirContext" factory-bean="ldapContextSource" factory-method="getReadOnlyContext" scope="session"/>

    <bean id="singleLdapContextSource" class="org.springframework.ldap.core.support.SingleContextSource" scope="session">

    <bean id="singleLdapTemplate" class="org.springframework.ldap.core.LdapTemplate" scope="session">

Spring 安全配置:

spring-security.xml:

Spring Security configuration:

spring-security.xml:
