java Spring集成LastModifiedFileListFilter不工作

Question

我正试图从一个目录中读取一些文件，在检测到文件和处理文件之间有一个延迟。 我有一个生成器模式：

/**
 * The build function that will create a CompositeFileListFilter with the given filters
 * 
 * @return {@link CompositeFileListFilter} that contains all the filters added
 */
public CompositeFileListFilter<File> build() {
    CompositeFileListFilter<File> compositeFileListFilter = new CompositeFileListFilter<>();
    boolean existsFilters = false;
    // Add the prevent duplicates filter
    if (this.preventDuplicates) {
        compositeFileListFilter.addFilter(new AcceptOnceFileListFilter<File>());
        existsFilters = true;
    } else {
        compositeFileListFilter.addFilter(new AcceptAllFileListFilter<File>());
        existsFilters = true;
    }
    // Add the ignore hidden filter
    if (this.ignoreHidden) {
        compositeFileListFilter.addFilter(new IgnoreHiddenFileListFilter());
        existsFilters = true;
    } // Add the pattern file name filter
    if (this.patternFilter != null) {
        compositeFileListFilter.addFilter(new SimplePatternFileListFilter(patternFilter));
        existsFilters = true;
    }
    // Add the process file after a period of time filter
    if (this.lastModifiedFileListFilterAge > 0) {
        LastModifiedFileListFilter filter = new LastModifiedFileListFilter();
        filter.setAge(lastModifiedFileListFilterAge);
        compositeFileListFilter.addFilter(filter);
        existsFilters = true;
    }

    // Check if compositeFileListFilter contains any filter
    if (!existsFilters) {
        throw new IllegalStateException("At least one filter should be provided!");
    }
    return compositeFileListFilter;
}

我正在创建这样的过滤器

CompositeFileListFilter<File> filters = new IntegrationFlowFileFilterBuilder()
        .ignoreHidden(true)
        .preventDuplicates(false)
        .patternFilter(returnInformationInputFolderSetup.getPatternFolder())
        .lastModifiedFileListFilterAge(120)
        .build();

问题是所有其他过滤器都在工作，只有LastModifiedFileList过滤器不工作。。我正在读一个文件，不到一秒钟就被处理了
有人知道为什么这个过滤器不工作吗
