Question

当我使用此ftps设置时

<property name="cipherSuites" value="a,b.c"/>

我正在异常

这是我的配置设置

<bean id="ftpsDefaultSessionFactory" class="org.springframework.integration.ftp.session.DefaultFtpsSessionFactory"           scope="prototype">
        <property name="host" value="127.0.0.1"/>
        <property name="port" value="22"/>
        <property name="username" value="ftpuser"/>
        <property name="password" value="neeraj"/>
        <property name="clientMode" value="2"/>
        <property name="fileType" value="2"/>
        <property name="useClientMode" value="true"/>
        <property name="cipherSuites" value="a,b.c"/>
        <property name="keyManager" ref="keyManager"/>
        <property name="trustManager" ref="trustManager"/>
        <property name="wantsClientAuth" value="false"/>
        <property name="needClientAuth" value="true"/>
        <property name="sessionCreation" value="true"/>
        <!--<property name="authValue" value="neeraj"/>-->
        <property name="protocol" value="SSL"/>
        <property name="prot" value="P"/>
        <property name="implicit" value="false"/>
         <property name="protocols" value="SSL, TLS"/>
    </bean>

我是从http://docs.spring.io/spring-integration/reference/html/ftp.html引用这些设置的。

有人有任何想法，我将如何解决这个问题？

Answer 1

<property name="cipherSuites" value="a,b.c"/>

它们不是真正的密码套件，doc只显示可用属性而不是它们的实际值。

除非您有特殊要求，否则您通常不需要提供该物业。

Answer 2

请参阅org.apache.commons.net.ftp.FTPSClient API和文档，您应该能够正确配置DefaultFtpsSessionFactory。希望在创建FTPSClient实例时使用默认值，您可能不需要在DefaultFtpsSessionFactory中设置所有其他属性。
