解析application.properties代码

package util;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.Properties;
public class PropertiesUtil {
private static final String DEFAULT_PROPERTIES="/application.properties";
/**
 * 获取properties属性值
 */
public static String getPropValue(String propKey){
    try {
        Properties props = new Properties();
        InputStream inputStream = PropertiesUtil.class.getResourceAsStream(DEFAULT_PROPERTIES);
        //*.properties配置文件，要使用UTF-8编码，否则会现中文乱码问题
        BufferedReader bf = new BufferedReader(new InputStreamReader(inputStream,"UTF-8"));
        props.load(bf);
        return props.getProperty(propKey);
    }catch (IOException e){
        e.printStackTrace();
    }
    return null;
