原因是與下面這個類上面的@Component衝突了
@Component //不加這個註解的話, 使用@Autowired 就不能注入進去了 public class AppProperties extends PropertyPlaceholderConfigurer { private static Map<String, String> ctxPropertiesMap; @Override protected void processProperties( ConfigurableListableBeanFactory beanFactory, Properties props) throws BeansException { super.processProperties(beanFactory, props); ctxPropertiesMap = new HashMap<String, String>(); for (Object key : props.keySet()) { String keyStr = key.toString(); String value = props.getProperty(keyStr); ctxPropertiesMap.put(keyStr, value); } } public static String getValue(String key) { return ctxPropertiesMap.get(key); } }
排查方法:
1.網上搜索,沒找到正確方法
2.把所有檔案全刪掉,然後一點一點恢復 最終發現問題檔案
