ResourceBundle.getBundle()來讀取自定義的properties配置文件

 

public class CreateHbaseTableDemo {
    public static void main(String[] args) {
        ResourceBundle resourceBundle= ResourceBundle.getBundle("hbase.properties");
        String port = resourceBundle.getString("zookeeperPort");
        String threadMax = resourceBundle.getString("threadMax");
        String keyValueMaxSize = resourceBundle.getString("KeyValueMaxSize");
        System.out.println(port);
        System.out.println(threadMax);
        System.out.println(keyValueMaxSize);
 
 
    }
}

 

springboot方式

自定義properties配置文件

test.name=aaa
test.age=ssss
