Весенняя интеграция: ошибка аутентификации входящего адаптера sftp

Question

Я использую входящий адаптер sftp для загрузки файлов каждый день в 8:00, поэтому для этого я объявляю учетные данные (пользователь и пароль) в файл user.properties.

аутентификация не удалась при выполнении этого, но приступить, если я пишу пароль непосредственно в application-context.xml.

Мой исходный код:

<bean id="defaultSftpSessionFactory" 
     class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory"> 

     <property name="host" value="${host}" /> 
     <property name="port" value="${port}" /> 
     <property name="user" value="${user}" /> 
     <property name="privateKey" value="${private.keyfile}"/> 
     <property name="privateKeyPassphrase" value="${passphrase}"/> 

     <property name="allowUnknownKeys" value="true" /> 
    </bean>

Answer 1

Стандартная функция от Spring по этому вопросу называется как property-placeholder. И вы точно используете его стиль в свойствах населения.

Но, похоже, у вас нет инфраструктуры-заполнителя. Что-то вроде этого:

<context:property-placeholder location="classpath:user.properties"/> 

Посмотрите для получения дополнительной информации в Spring Framework Reference Manual.
