1、通过spring配置properties文件
[java]
其中class为自己定义的类
2、自定义类CustomizedPropertyPlaceholderConfigurer
[java]
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PropertyPlaceholderConfigurer返回properties内容
*
* @author LHY 2012-02-24

*/
public class CustomizedPropertyPlaceholderConfigurer extends
PropertyPlaceholderConfigurer {
private static Map
@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);
} www.2cto.com
}
public static Object getContextProperty(String name) {
return ctxPropertiesMap.get(name);
}
}
这样就可以通过CustomizedPropertyPlaceholderConfigurer类来获取properties属性文件中的内容了
3、如何获取属性文件的内容
String host = (String) CustomizedPropertyPlaceholderConfigurer.getContextProperty("mail.smtp.host");
