java_之读取属性文件

1.属性文件为config.properties
weibo.qq.username=i_wudl,xiaoxiao,GuoJinPanlb
weibo.qq.appKey=801381870
weibo = 1017743154,wudl,haha
2.读取文件为
package com.wu.domain;
import java.util.Arrays;
import java.util.List;
import org.apache.commons.configuration.Configuration;
import org.apache.commons.configuration.ConfigurationException;
import org.apache.commons.configuration.PropertiesConfiguration;
import org.apache.log4j.Logger;
public class PropertyConfig {
public static final Logger log = Logger.getLogger(PropertyConfig.class);
private static Configuration config;
static{
try {
config = new PropertiesConfiguration("config.properties");
} catch (ConfigurationException e) {
e.printStackTrace();
}
}
public static String getValueByKey(String key){
return config.getString(key);
}
public static Long getLongValueByKey(String key){
return config.getLong(key);
}
public static String[] getArrayValueByKey(String key){
return config.getStringArray(key);
}
public static List<String> getListValueByKey(String key){
return Arrays.asList(getArrayValueByKey(key));
}
public static List<Object> getListByKey(String key){
return config.getList(key);
}
}
3.测试文件
package com.wu.domain;

import java.util.List;

import org.apache.log4j.Logger;
public class TestProperty {
public static final Logger log = Logger.getLogger(TestProperty.class);
public static void main(String[] args) {
PropertyConfig p = new PropertyConfig();
//读取一个
String[] namesArr = p.getArrayValueByKey("weibo.qq.username");
log.info("namesArr---"+namesArr);
for(String username : namesArr)
{
System.out.println("username---"+username);
}
//获取一个
String str = p.getValueByKey("weibo.qq.appKey");
System.out.println(str);
List list = p.getListByKey("weibo");
for (int i = 0; i < list.size(); i++) {
System.out.println(list.get(i));
}
}
}
