java – 验证文件spring-ldap.xsd时出错

我在我的bean配置中有这个错误,但是对于另一个项目工作.. xml是：

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

但是在一个项目中我有这个错误：

referenced file contains error http://www.springframework.org/schema/ldap/spring-ldap.xsd

解决方法:

更新：

我像这样修改我的光束并且工作(我添加conf.用于汇集但不重要)：

<!-- LDAP config -->

    <bean id="contextSourceTarget" class="org.springframework.ldap.core.support.LdapContextSource">
        <property name="url" value="${ldap.url}" />
        <property name="base" value="${ldap.base}" />
        <property name="userDn" value="${ldap.userDn}" />
        <property name="password" value="${ldap.password}" />
        <property name="pooled" value="false" />
    </bean>

    <bean id="contextSource"
        class="org.springframework.ldap.pool.factory.PoolingContextSource">
        <property name="contextSource" ref="contextSourceTarget" />
    </bean>

    <bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
        <constructor-arg ref="contextSource" />
    </bean>
