我无法弄清问题在哪里,我的jar文件没有这个配置文件夹在此输入图像描述

DaoMain.java

package org.postprocessor.dao;

import org.postprocessor.util.FileZipper;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class DaoMain {
    public static void main(String[] args) {

        DaoImpl daoImpl=null;
        FileZipper fileZipper=null;
        try{
            daoImpl= ctx.getBean("daoImpl",DaoImpl.class);
            fileZipper= ctx.getBean("fileZipper",FileZipper.class);
            daoImpl.startProcess();
            fileZipper.zipFile(new File("").getAbsolutePath()+"/output");
        }
        catch(Exception e){
            e.printStackTrace();
        }

看起来主要问题在于这一行:

new ClassPathXmlApplicationContext("classpath:/org/postprocessor/config/dataSupport.xml");
Run Code Online (Sandbox Code Playgroud)

您正在尝试构建上下文classpath.因此,您必须找到可从项目的类路径访问的配置文件.

您使用Maven来构建项目.Maven为代码源和资源定义了项目结构:

/src/main/java  
/src/main/resorces
Run Code Online (Sandbox Code Playgroud)

您可以在此处找到更多信息:标准目录布局简介

如果你想让你的文件可以从类路径访问,你必须把它放在 - resources/文件夹下:

在此输入图像描述

现在你main()将会是这样的:

public static void main(String[] args) {
    ApplicationContext ctx= new ClassPathXmlApplicationContext("classpath:config/dataSupport.xml");
    Object dataSource = ctx.getBean("userRepo");
    System.out.println(dataSource.getClass().getName());
    // use your beans here

我创建了只是demo bean.这是输出:

顺便说一句,您可以使用资源尝试应用程序上下文:

try(ClassPathXmlApplicationContext ctx =
    new ClassPathXmlApplicationContext("classpath:config/dataSupport.xml")) {
    // use your beans here
}
