程序获取spring加载属性文件

import java.util.HashSet;
import java.util.Properties;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.beans.factory.config.PropertyPlaceholderConfigurer;

/**这里不用<context:property-placeholder/>
* 重写了PropertyPlaceholderConfigurer 类,在spring配置文件加载
* @author lyq

*/
public class MyPropertyPlaceholderConfigurer extends PropertyPlaceholderConfigurer {
  @SuppressWarnings("deprecation")
  @Override
  protected void processProperties(ConfigurableListableBeanFactory beanFactoryToProcess,
      Properties props) throws BeansException {
      super.processProperties(beanFactoryToProcess, props);
//      resolvedProps = new HashMap<String, String>();
      for (Object key : props.keySet()) {
          String keyStr = key.toString();
          ConfigContainer.props.put(keyStr, parseStringValue(props.getProperty(keyStr), props,new HashSet()));
      }
  }
}


<bean id="configBean"
class="com.gainthink.prop.MyPropertyPlaceholderConfigurer">
<property name="locations">
<value>classpath*:*.properties</value>
</property>
</bean>



import java.util.HashMap;
import java.util.Map;

public class ConfigContainer {
static Map<String,String> props = new HashMap<String, String>();
public static String getProperty(String key){
  return props.get(key);
  }
}




最后执行程序
ApplicationContext context = new ClassPathXmlApplicationContext("application.xml"); 
System.out.println(ConfigContainer.getProperty("interval.time"));
