Question

我在使用最简单的maven-spring应用程序时遇到了一些困难。实际上，BeanFactory找不到appContext.xml文件，尽管它位于资源目录中并正确复制到目标目录中。这是我的主要类，dir结构和错误：

// MAIN CLASS
package sas.test.spring;

import java.io.FileInputStream;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.Resource;

/**
 * Hello world!
 */
public class App {
    public static void main(String[] args) throws Exception {
        System.out.println("Hello World!");

        BeanFactory fact = new XmlBeanFactory((Resource) new FileInputStream("appContext.xml"));

        GreetingService gs = (GreetingService) fact.getBean("greetingService");

        gs.sayGreeting();

    }
}

mvn compile之后的目录结构：

testspring002
|--src
|  `--main
|     |--java
|     |  `--sas
|     |     `--test
|     |        `--spring
|     |           |--App.java
|     |           |--GreetingService.java
|     |           `--GreetingServiceImpl.java
|     `--resources
|        `--appContext.xml
...
`--target
   `--classes
      |--appContext.xml
      `--sas
         `--test
            `--spring
               |--App.class
               |--GreetingService.class
               `--GreetingServiceImpl.class

这是错误：

appContext.xml (No such file or directory)

有什么建议吗？

Answer 1

谢谢，这个提示做到了。没意识到FileInputStream可能是个问题。但是，我现在使用ApplicationContext并且它可以工作：

ApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"appContext.xml"});

谢谢＆amp;干杯

Answer 2

是的，因为应用程序上下文XML在/ classes中，这意味着它位于CLASSPATH中。我建议从类加载器调用getResourceAsStream（）来获取InputStream而不是FileInputStream。

简单的Spring-Maven HelloWorld - ＆gt;找不到appContext.xml？
