Java获取resources下配置文件信息

用配置文件获取信息 （通过new property）

package org.example;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
public class TestProperty {
    public static void main(String[] args) {
        Properties properties = new Properties();
        properties.setProperty("tablename","hello-kitty");
        String[] tablenames = properties.getProperty("tablename").split("-");
        for (String tablename: tablenames){
            System.out.println(tablename);
        }

        /*获取  配置文件的属性--这样就不必把配置写死,可以灵活的在配置文件统一*/
        //文件要放到resource目录下
        /*获取资源文件,一般推荐采用这种方式读取*/
        InputStream path = Thread.currentThread().getContextClassLoader().getResourceAsStream("message.properties");
        Properties newproperties = new Properties();
        try {
            newproperties.load(path);
        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println(newproperties.getProperty("pg.host"));
        System.out.println(newproperties.getProperty("pg.port"));
    }
}

文件和结果如下
