Spring集成-SpelEvaluationException：操作符'；添加'；类型为'；java.lang.String'；和'；空'；

我有一个Spring批处理/集成作业，它应该轮询FTP服务器，获取所有的.txt文件，使用Spring批处理组件转换它们，然后将它们放入队列（使用ActiveMQ实现）。但是，我在尝试从FTP区域检索文件时遇到以下错误：

ERROR [org.springframework.integration.handler.LoggingHandler] - <org.springframework.expression.spel.SpelEvaluationException: EL1030E:(pos 0): The operator 'ADD' is not supported between objects of type 'java.lang.String' and 'null'

（部分）FileMessageListener.java：

public class FileMessageListener implements MessageListener {

    private static final Logger logger = Logger.getLogger(FileMessageListener.class);

    public void onMessage(Message message) {
        try {
            logger.info("Received file " + message.getStringProperty("fileName"));
        } catch (JMSException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

我正在测试这个设置

public class FileListener {
    private static final Logger logger = Logger.getLogger(FileListener.class);
    private static final String CONFIG = "/launch-context.xml";

    public static void main(String[] args) throws Exception {
        logger.debug("FileListener started");
        new ClassPathXmlApplicationContext(CONFIG);
    }
}

2015-03-09 10:07:10041错误[org.springframework.integration.handler.LoggingHandler]-我把它作为一个答案

第一个错误是因为在执行操作时传递了null
本地文件名生成器表达式=“+#this
”。尝试提供值似乎可以解决此问题
本地文件名生成器表达式=“'sample'+#this”

注释中的第二个错误是由于方法签名。下面的方法将
消息
作为arg，而它的调用者将io.File作为arg传递。因此出现了错误。根据提供的信息，我不确定打电话的人在哪里，但这应该能告诉你错误的要点

public JobLaunchRequest toRequest(Message<File> message) {
        JobParametersBuilder jobParametersBuilder =
            new JobParametersBuilder();

public job启动请求到请求（消息）{
作业参数生成器作业参数生成器=
新作业参数builder（）；
我通过使用

  <int:service-activator id="runJob" method="launch" input-channel="outboundJobRequestChannel"
        output-channel="statuses">
        <bean class="org.springframework.batch.integration.launch.JobLaunchingMessageHandler">
            <constructor-arg ref="jobLauncher"/>
        </bean>
    </int:service-activator>



而不是

<batch-int:job-launching-gateway request-channel="outboundJobRequestChannel"
                                   reply-channel="jobLaunchReplyChannel"
                                   job-launcher="jobLauncher" />



然后将toRequest方法的参数更改为（java.io.File文件）。现在一切正常。感谢@minion的帮助。
我想问题可能在这里。本地文件
public JobLaunchRequest toRequest(Message<File> message) {
        JobParametersBuilder jobParametersBuilder =
            new JobParametersBuilder();

  <int:service-activator id="runJob" method="launch" input-channel="outboundJobRequestChannel"
