无效的捆绑上下文异常

Question

我正在使用Apache Camel从使用SFTP的服务器中提取文件。我的代码正从

sftp:/example.com:22/dev139/uploads/alamo?username=admin&password=admin&binary=true&disconnect=true&delete=true

它可以成功地从这个目录中抓取文件，因为我可以在日志中看到文件内容，但它随后会抛出以下异常。

public class FromAlamoRouteBuilder extends RouteBuilder implements
    InitializingBean, DisposableBean {

@EnforceInitialization
private String DEAD_LETTER_MQ = "";

@EnforceInitialization
private String ALAMO_SFTP_SOURCE;   

@EnforceInitialization
private String DESTINATION_QUEUE;  


@EnforceInitialization(preventZero = false)
private int exceptionMaximumRedeliveries;

@EnforceInitialization(preventZero = false)
private int exceptionMaximumRedeliveriesDelay;  



public void configure() throws Exception {

    onException(Exception.class)
        .handled(true)
        .retriesExhaustedLogLevel(LoggingLevel.ERROR)
        .retryAttemptedLogLevel(LoggingLevel.WARN)
        .maximumRedeliveries((int) exceptionMaximumRedeliveries)
        .redeliveryDelay((int) exceptionMaximumRedeliveriesDelay)
        .bean("logging", "error(*, '${exception.stacktrace}')")
        .to(DEAD_LETTER_MQ)
        .stop();

    /*
     * The exchange body is expected to be an Alamo CSV file
     */ 
    from(ALAMO_SFTP_SOURCE)
        .routeId("FromAlamoSFTP")
        .setExchangePattern(ExchangePattern.InOnly)
        .bean("logging", "info(*, 'Received message " + ALAMO_SFTP_SOURCE  + "[${body}]')")
        .setHeader(MsgHdr.MESSAGE_TYPE, constant("AlamoCSV"))
        .setHeader(MsgHdr.MESSAGE_DESTINATION, constant("CDX"))
        .bean("logging", "info(*, 'Attempting to place Alamo msg on DESTINATION QUEUE " + DESTINATION_QUEUE + "')")
        .to(DESTINATION_QUEUE)      
        .bean("logging", "info(*, 'Successfully placed Alamo msg on " + DESTINATION_QUEUE + "')");

}

public void setDeadLetterQueue(String dEAD_LETTER_MQ) {
    DEAD_LETTER_MQ = dEAD_LETTER_MQ;
}

public void setExceptionMaximumRedeliveries(int exceptionMaximumRedeliveries) {
    this.exceptionMaximumRedeliveries = exceptionMaximumRedeliveries;
}

public void setExceptionMaximumRedeliveriesDelay(
        int exceptionMaximumRedeliveriesDelay) {
    this.exceptionMaximumRedeliveriesDelay = exceptionMaximumRedeliveriesDelay;
}

public void setDestinationQueue(String queue){
    this.DESTINATION_QUEUE = queue;  
}

public void setAlamoSftpSource(String bcRelease){
    this.ALAMO_SFTP_SOURCE = bcRelease;
}

public void afterPropertiesSet() throws Exception {
    System.out.println("FromAlamoRouteBuilder is starting up");
    FieldInitialization.checkAllFields(this);
} 


public void destroy() throws Exception {
    System.out.println("FromAlmoRouteBuilder is shutting down");
}
}

我找到了解决这个问题的办法。这是服务器配置中的一个错误，而不是与我的代码相关的错误。感谢大家的帮助
