From source file:org.springframework.boot.autoconfigure.AutoConfigurationImportSelector.java

private List<String> filter(List<String> configurations, AutoConfigurationMetadata autoConfigurationMetadata) {
    long startTime = System.nanoTime();
    String[] candidates = StringUtils.toStringArray(configurations);

    boolean skipped = false;
    for (AutoConfigurationImportFilter filter : getAutoConfigurationImportFilters()) {
        invokeAwareMethods(filter);/*from  w  w w. java  2 s  . c o  m*/
        boolean[] match = filter.match(candidates, autoConfigurationMetadata);
        for (int i = 0; i < match.length; i++) {
