一:首先创建一个属性文件xxx.properties
二:然后自定义一个属性加载类工具类,必须要extends PropertyPlaceholderConfigurer类,(实际是对PropertyPlaceholderConfigurer类的一个扩展)
public class CustomizedPropertyConfigurer extends PropertyPlaceholderConfigurer {
private static Map<String, Object> ctxPropertiesMap;
@Override
protected void processProperties(
ConfigurableListableBeanFactory beanFactoryToProcess,
Properties props) throws BeansException {
super.processProperties(beanFactoryToProcess, props);
ctxPropertiesMap = new HashMap<String, Object>();
for (Object key : props.keySet()) {
String keyStr = key.toString();
