在maven项目中的​​pom.xml​​中配置：

<dependency>
    <groupId>org.ini4j</groupId>
    <artifactId>ini4j</artifactId>
    <version>0.5.4</version>
</dependency>

​​env.ini​​文件：

[dev]
url="dev-url"
user="dev-user"
password="dev-password"

[testing]
url=""
user=""
password=""

代码：

import org.ini4j.Ini;
import org.ini4j.Profile;
import org.ini4j.Wini;
import java.io.File;
import java.util.Map;
import java.util.Set;

public class IniUtils {
    public static void main(String[] args) {
        try {
            readIni();
        }catch (Exception e){
            System.out.println(e.getMessage());
        }
    }
    private static void readIni() throws Exception{
        Wini ini = new Wini(new File("yourPath/env.ini"));
        // read
        Ini.Section section = ini.get("dev");

        System.out.println(url);
        System.out.println(user);

        String url1 = map.get("url");
