Java中如何获取spring中配置文件.properties中属性值

通过spring配置properties文件

1 2 3 4 5 6 7 8 9

<bean id="propertyConfigurer"   class="com.hapishop.util.ProjectDBinfoConfigurer">   <property name="ignoreResourceNotFound" value="true" />   <property name="locations">       <list>           <value>/WEB-INF/config/dbinfo.properties</value>       </list>   </property> </bean>

其中class为自己定义的类

 

自定义类ProjectDBinfoConfigurer

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

import java.util.HashMap; import java.util.Map; import java.util.Properties;   import org.springframework.beans.BeansException; import org.springframework.beans.factory.config.ConfigurableListableBeanFactory; import org.springframework.beans.factory.config.PropertyPlaceholderConfigurer;   /**  * 自定义ProjectDBinfoConfigurer返回properties内容  * @ClassName: ProjectDBinfoConfigurer  * @Description: TODO (请用一句话描述该类做什么)  * @author ZhangYQ iitshare@itblood.com  * @date: 2012-11-20 下午11:48:32  */ public class ProjectDBinfoConfigurer extends PropertyPlaceholderConfigurer {     private static Map ctxPropertiesMap;       @Override     protected void processProperties(             ConfigurableListableBeanFactory beanFactoryToProcess,             Properties props) throws BeansException {         super.processProperties(beanFactoryToProcess, props);         ctxPropertiesMap = new HashMap();         for (Object key : props.keySet()) {             String keyStr = key.toString();             String value = props.getProperty(keyStr);             ctxPropertiesMap.put(keyStr, value);         }     }     public static Object getContextProperty(String name) {         return ctxPropertiesMap.get(name);     } }

这样就可以通过ProjectDBinfoConfigurer类来获取properties属性文件中的内容了

如何获取属性文件的内容

String url= (String) ProjectDBinfoConfigurer.getContextProperty(“jdbc.url”);
