SpringBoot自定义配置文件读取

有时候我们把配置都放到application.yml文件里面会造成此文件相当不好管理，所以我们可以有意识的进行拆分，将一些配置放到其他的配置文件里面，那么我们如何加载并使用它呢，其实很简单，直接读取然后放到Properties对象中就OK了，看代码

读取配置

package com.pibgstar.demo.utils;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.util.StringUtils;

import java.io.IOException;
import java.io.InputStream;
import java.io.UnsupportedEncodingException;
import java.util.Properties;

/**

 * @desc 加载配置文件
 **/
public class ConfigUtil {
    private static Logger logger = LoggerFactory.getLogger(ConfigUtil.class);
    // 配置文件的路径
    private static final String CONFIG_NAME = "conf/config.properties";
    private static Properties ps;

    public static int getInt(String key) {
        String value = getValue(key);
        return Integer.parseInt(value);
    }

    public static String getString(String key) {
        String value = getValue(key);
        try {
            return new String(value.getBytes("iso-8859-1"),"utf-8");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return "";
    }

    private static String getValue(String key) {
        if (ps == null) {
            init();
        }
        String value = null;
        if (StringUtils.isEmpty(value)) {
            value = ps.getProperty(key);
        }
        logger.info("key:"+key+"----value:"+value);
        return value;
    }

    private static synchronized void init() {
        try {
            InputStream ras = ConfigUtil.class.getClassLoader().getResourceAsStream(CONFIG_NAME);
            ps = new Properties();
            ps.load(ras);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

配置文件放置

我们将config.properties放到resources下新建的conf文件夹下面就OK了

pibigstar.demo.url=http://www.pibigstar.com
pibigstar.demo.number=8

使用

public class TestConfigUtil {
    public static void main(String[] args){
        String url = ConfigUtil.getString("pibigstar.demo.url");
        int number = ConfigUtil.getInt("pibigstar.demo.number");
        System.out.println(url + "  " + number);
    }
}
