使用bat调用可执行jar文件

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
