使用ClassPathXmlApplicationContext的applicationContext.xml的正确路径 [英] Right path to applicationContext.xml using ClassPathXmlApplicationContext

问题描述

我在WEB-INF / config / applicationContext.xml中使用applicationContext.xml处理web应用程序。现在我需要将一些测试工具实现为独立应用程序，它可以使用相同的applicationContext.xml，但是对于ClassPathXmlApplicationContext类的配置路径有问题。

I have working web-application with applicationContext.xml in WEB-INF/config/applicationContext.xml. Now i need to implement some testing tool as standalone application, that can use the same applicationContext.xml, but have problem with path to config for ClassPathXmlApplicationContext class.

我知道当我将applicationContext.xml复制到默认包（其中.java驻留）时，我可以使用ClassPathXmlApplicationContext（applicationContext.xml），但这是必要的吗？

I know that when i copy applicationContext.xml to default package (where .java resides) i can use ClassPathXmlApplicationContext("applicationContext.xml"), but is this necessary ?

import org.apache.log4j.Logger;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class AdminTool {

    private Logger log = Logger.getLogger(getClass());

    /** all below doesn't work - FileNotFoundException) **/
    private static final ApplicationContext ac = new ClassPathXmlApplicationContext("/WEB-INF/config/applicationContext.xml");
    private static final ApplicationContext ac = new ClassPathXmlApplicationContext("config/applicationContext.xml");
    private static final ApplicationContext ac = new ClassPathXmlApplicationContext("../config/applicationContext.xml");

    public static void main(String[] args) {
        new AdminTool();
    }

    public AdminTool() {
        log.debug(ac);
    }

}

推荐答案

在本地测试场景中，您不在Jar中，因此您不需要基于Classpath的访问。使用 FileSystemXmlApplicationContext 。

In a local test scenario, you are not inside a Jar, so you don't need Classpath-based access. Use FileSystemXmlApplicationContext instead.

可能是这样的：

private static final ApplicationContext ac =
    new FileSystemXmlApplicationContext(
        "src/WEB-INF/config/applicationContext.xml"
    );

（路径与执行目录相对）

(paths are relative from the execution directory)
