Java中讀取Properties文件中的配置信息

配置文件：config.properties

配置文件的路徑：src/main/resources/static/config.properties

ip = 127.0.0.1
port = 8080
filepath = D:/download
username = root
password = 123456

一、使用阿里的fastjson

<!-- fastjson包 -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.4</version>
</dependency>

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.Properties;

import com.alibaba.fastjson.JSONObject;

public class getPropertys {

	public static void main(String[] args) throws IOException {
		Properties properties = new Properties();
		// 使用InPutStream流讀取properties文件
		BufferedReader bufferedReader = new BufferedReader(new FileReader("src/main/resources/static/config.properties"));
		properties.load(bufferedReader);
		JSONObject obj = new JSONObject();
		obj.put("ip",properties.getProperty("ip"));
		obj.put("port",properties.getProperty("port"));
		obj.put("filepath",properties.getProperty("filepath"));
		obj.put("username",properties.getProperty("username"));
		obj.put("password",properties.getProperty("password"));
		System.out.println(obj.toString());
	}
	
}

 

二、使用google的gson

<!-- gson包 -->
<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.5</version>
</dependency>

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.Properties;

import com.google.gson.JsonObject;

public class getPropertys {

	public static void main(String[] args) throws IOException {
		Properties properties = new Properties();
		// 使用InPutStream流讀取properties文件
		BufferedReader bufferedReader = new BufferedReader(new FileReader("src/main/resources/static/config.properties"));
		properties.load(bufferedReader);
		JSONObject obj = new JSONObject();
		JsonObject obj=new JsonObject();
		obj.addProperty("ip",properties.getProperty("ip"));
		obj.addProperty("port",properties.getProperty("port"));
		obj.addProperty("filepath",properties.getProperty("filepath"));
		obj.addProperty("username",properties.getProperty("username"));
		obj.addProperty("password",properties.getProperty("password"));
		System.out.println(obj.toString());
	}
	
}
