commons-configuration读取配置文件

关键工具类:

1. 1. import org.apache.commons.configuration.CompositeConfiguration;
   2. import org.apache.commons.configuration.ConfigurationException;
   3. import org.apache.commons.configuration.PropertiesConfiguration;   //</horsepower>
   4. </engine-config>

   2.读取properties文件
   [java] view plain copy

   print?

   1. import org.apache.commons.configuration.Configuration;
   2. import org.apache.commons.configuration.PropertiesConfiguration;
   3. public class PropertiesConfigurationExample {
   4. public static void main(String[] args) throws Exception {
   5. Configuration config = new PropertiesConfiguration(
   6. “com/discursive/jccook/configuration/global.properties” );
   7. System.out.println( “Speed: ” + config.getFloat(“speed”));
   8. System.out.println( “Names: ” + config.getString(“name”));
   9. }
   10. }

   [plain] view plain copy

   print?

   1. global.properties
   2. threads.maximum=50
   3. threads.minimum=20
   4. timeout=15.52
   5. interactive=true
   6. color=red
   7. speed=50
   8. name=Default User
   9. email=default@email.com
   10. region=Earth

   3.当有多个配置文件时,就利用ConfigurationFactory对象来访问多个不同的配置资源
   [java] view plain copy

   print?

   1. import java.net.URL;
   2. import java.util.List;
   3. import org.apache.commons.configuration.Configuration;
   4. import org.apache.commons.configuration.ConfigurationFactory;
   5. public class PropertiesXmlConfigurationExample {
   6. public static void main(String[] args) throws Exception {
   7. PropertiesXmlConfigurationExample example = new PropertiesXmlConfigurationExample();
   8. ConfigurationFactory factory = new ConfigurationFactory();
   9. URL configURL = example.getClass().getResource(“additional-xml-configuration.xml”);
   10. factory.setConfigurationURL( configURL );
   11. Configuration config = factory.getConfiguration();
   12. List startCriteria = config.getList(“start-criteria.criteria”);
   13. System.out.println( “Start Criteria: ” + startCriteria );
   14. int horsepower = config.getInt(“horsepower”);
   15. System.out.println( “Horsepower: ” + horsepower );
   16. }
   17. }

   [html] view plain copy

   print?

   1. additional-xml-configuration.xml
   2. <?xml version=”1.0″ encoding=”ISO-8859-1″ ?>
   3. <configuration>
   4. <properties fileName=”global.properties”/>
   5. <xml fileName=”global.xml”/>
   6. </configuration>

   4.CompositeConfiguration,手动加上两个配置文件
   [java] view plain copy

   print?

   1. import org.apache.commons.configuration.CompositeConfiguration;
   2. import org.apache.commons.configuration.ConfigurationException;
   3. import org.apache.commons.configuration.PropertiesConfiguration;
   4. import org.apache.commons.configuration.XMLConfiguration;
   5. public class Test {
   6. /**
   7. * @param args
   8. * @throws ConfigurationException
   9. */
   10. public static void main(String[] args) throws ConfigurationException {
   11. // TODO Auto-generated method stub
   12. CompositeConfiguration config = new CompositeConfiguration();
   13. config.addConfiguration(new PropertiesConfiguration(
   14. “com/discursive/jccook/configuration/global.properties” ));
   15. config.addConfiguration( new XMLConfiguration
   16. (“com/discursive/jccook/configuration/global.xml”));
   17. List startCriteria = config.getList(“start-criteria.criteria”);
   18. int horsepower = config.getInt(“horsepower”);
   19. System.out.println( “Start Criteria: ” + startCriteria );
   20. System.out.println(horsepower);
   21. System.out.println( “Speed: ” + config.getFloat(“speed”));
   22. System.out.println( “Names: ” + config.getString(“name”));
   23. }
   24. }
