spring-config文件中旧版本的spring-integration-sftp给出XML错误，而3.0.2版给出outbound-channel-adapter的错误。

Question

Please see the beginning of the spring-integration-config file below. If I have the reference to spring-integration-sftp (not version 3.02.) in the schema location I am receiving the following error:

Referenced file contains errors ( http://www.springframework.org/schema/integration/spring-integration-2.0.xsd ).

However, if I switch to the 3.0.2 version of spring-integration-sftp I am getting the following error:

The matching wildcard is strict, but no declaration can be found for element 'int-sftp:outbound-channel-adapter'.

The spring-integration-config.xml code related to spring-integration-sftp is as follows:

<bean id="sftpSessionFactory"
    class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">
    <property name="host" value="${seaWorldOrlando.sftp.host}" />
    <property name="port" value="${seaWorldOrlando.sftp.port}" />
    <property name="user" value="${seaWorldOrlando.sftp.user}" />
    <property name="password" value="${seaWorldOrlando.sftp.password}" />
</bean>

<int-sftp:outbound-channel-adapter
    id="sftpOutboundAdapter" channel="toFtp" charset="UTF-8"
    remote-directory="/home/request" session-factory="sftpSessionFactory" />

The beginning of the spring-integration-config file is as follows:

Our recommendation do not use versions for XSD at all. The framework read the latest one from classpath. it allow you to avoid changes after upgrade.

From other side, if you mention 3.0.2 be sure you use correct jars of Spring Integration. And all of them should be the same version.

If you have some doubts with allowed attributes, take a look into correct XSD, if they are present. You can find them in the appropriate jar, eg org/springframework/integration/sftp/config/spring-integration-sftp-3.0.xsd .
