我无法弄清问题在哪里，我的jar文件没有此配置文件夹

DaoMain.java

package org.postprocessor.dao;

import java.io.File;

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) {
        ApplicationContext ctx= new ClassPathXmlApplicationContext("classpath:/org/postprocessor/config/dataSupport.xml");
        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();
        }
        finally{
            ((ClassPathXmlApplicationContext) ctx).close();
        }
      }
    }

如何解决此问题？

Answer 1

看起来主要问题出在这一行：

new ClassPathXmlApplicationContext("classpath:/org/postprocessor/config/dataSupport.xml");

您正尝试从classpath构建上下文。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

您可以在此处找到更多信息：Introduction to the Standard Directory Layout

如果您想要从类路径访问您的文件， 必须将其完全置于 - resources/文件夹下：

现在您 main（） 将是：

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

我只创建了demo bean。这是输出：

2017-03-20 15:22:40 INFO  ClassPathXmlApplicationContext - Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@16f65612: startup date [Mon Mar 20 15:22:40 EET 2017]; root of context hierarchy
2017-03-20 15:22:40 INFO  XmlBeanDefinitionReader - Loading XML bean definitions from class path resource [config/dataSupport.xml]
demo.repository.UserRepository

BTW 您可以将try with resources用于应用程序上下文：

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

其他资源 ：

Answer 2

您的XML文件格式不正确。

虽然我不知道这是否是问题，但这可能是您的项目首先没有正确处理文件的根本原因。

您的<beans>标记没有结束标记。尝试将</beans>放在文件的末尾。

此外，您的pom.xml文件也有同样的问题。 <project>未关闭。尝试将</project>放在文件的末尾。

Answer 3

我认为以下内容应该有效：

//server/ddp.js let myConn = DDP.connect('http://localhost:5000'); //server/method.js myConn.call('myMethod', {obj}, () => {})

您不需要指定＆＃34; classpath＆＃34;因为你已经使用了ClassPathXmlApplicationContext，并且在开头就有了额外的斜杠。

Answer 4

举：

src/org/postprocessor/config/dataSupport.xml

为：

src/main/resources/org/postprocessor/config/dataSupport.xml

Answer 5

默认情况下，maven-compiler-plugin不包含非java文件。这给你留下了两个选择 1.将您的资源文件（.properties，.xml等）移动到＆＃34; src / main / resources＆＃34; （ recomended 。）
2.使用maven资源插件
