【问题描述】：
我正在使用 Spring Boot 开发一个项目，我需要添加 Spring 集成轮询器以从某个位置轮询文件并在该文件上运行 Spring Batch 以对其进行处理。
我为此使用了 spring 批处理集成（下面的文档参考。）
http://docs.spring.io/spring-batch/trunk/reference/html/springBatchIntegration.html
在 Spring Boot 中，我已成功在 @Configuration 文件中配置了我的轮询器，如下所示
@Bean
@InboundChannelAdapter(value = "fileInputChannel", poller = @Poller(
fixedRate = "1000"), autoStartup = "true")
public MessageSource<File> filesScanner() {
CompositeFileListFilter<File> filters = new CompositeFileListFilter<File>();
filters.addFilter(new SimplePatternFileListFilter("*.xml"));
filters.addFilter(new AcceptOnceFileListFilter<File>());
filters.addFilter(getLastModifiedFileFilter());
FileReadingMessageSource source = new FileReadingMessageSource();
source.setDirectory(new File("F:/DataInput/"));
source.setFilter(filters);
return source;
}
此轮询器在 java 配置中定义，而通道在 xml 中定义如下。

我的 XML 配置文件中出现以下错误。
cvc-complex-type.3.2.2：属性“fixed-rate”不允许出现在元素“int:poller”中。
我在谷歌上检查了这个，发现只有下面的链接没有多大用处，因为我得到了完全相同的错误。
Using Spring Boot & Spring Integration with database backed Configuration
Attribute 'fixed-rate' is not allowed to appear in element 'int:poller'
我使用的Spring Boot版本如下。
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.6.RELEASE</version>
库中的 Spring 集成 jar - Spring-integration-core-4.2.8.RELEASE.jar
我还尝试从批处理集成依赖项中排除集成 jar，并单独添加它，如下所示，但这也不起作用。
<dependency>
<groupId>org.springframework.batch</groupId>
<artifactId>spring-batch-integration</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-core</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.integration/spring-integration-core -->
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-core</artifactId>
</dependency>
还检查了 XSD http://www.springframework.org/schema/integration/spring-integration.xsd，它在轮询器中具有固定延迟属性。有解决此问题的建议吗？
