Simple Spring -Maven HelloWorld & # 8594; not appContext.xml found?

Question

I'm having some difficulties with the simplest maven-w760 application. In fact, it BeanFactorydoes not find the file appContext.xml, despite the fact that it is in the resource directory and correctly copied to the target directory. Here is my main class, dir structure and error:

// 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();

    }
}

Directory structure after mvn compile:

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

And here is the error:

appContext.xml (No such file or directory)

Any suggestions?

Answer 1

Thank you, this hint did it. Did not understand that FileInputStream could be a problem. However, now I am using ApplicationContext and it works:

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

Thanks and greetings

, XML /classes, , CLASSPATH. getResourceAsStream() , InputStream FileInputStream.
