4.使用bat调用可执行jar文件

2023-08-04 21:40:22

一.项目需求

1.maven工程

2.有properties配置文件。

3.有内部jar包

二.简单的是实现实例

1.项目文件放置

注意：如果是web工程，我们会将jar文件当到我们项目WEB-INF/lib中路径下。

2.main方法代码

package com.my.tools.run;

import java.io.IOException;

import java.io.InputStream;

import java.util.Properties;

import com.my.util.Book;

/**

 * Hello world!

 *

 */

public class RunBat {

    public static void main(String[] args) {

        System.out.println("Welcom to this system");

        Properties prop = new Properties();

        InputStream in = RunBat.class.getClassLoader().getResourceAsStream("config/config.properties");

        try {

            prop.load(in);

            Book book = new Book(prop.getProperty("name"), Double.parseDouble(prop.getProperty("price")));

            System.out.println(book);

        } catch (IOException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

    }

}

3.pom配置
