如何将本地文件名传递给ClassPathXmlApplicationContext？

Question

"本地文件名"是指资源文件与类文件位于同一目录中.在下面的情况下,这是JUnitRunner.class文件.getResource()如果路径不以/'' 开头,则Java的文件可以处理此问题

我弄不清楚,如何做同样的ClassPathXmlApplicationContext构造函数？

package springtests;

import java.io.File;
import java.net.URISyntaxException;
import java.net.URL;

import org.junit.Test;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class JUnitRunner {

    private final static Logger log = LoggerFactory.getLogger(JUnitRunner.class);

    @Test
    public void test() throws URISyntaxException {

        String filename = "test01.xml";

        URL url = getClass().getResource(filename);


        File file = new File(url.toURI());
        log.info("File exists: {}", file.exists());

        try {
            new ClassPathXmlApplicationContext(filename);
        }
        catch(Exception e) {
            log.error("Can't load context", e);
        }

    }
}

输出如下

15:32:27,375 3    [main] INFO  springtests.JUnitRunner  - File exists: true
15:32:27,422 50   [main] INFO  org.springframework.context.support.ClassPathXmlApplicationContext  - Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@ee3aa7: startup date [Thu Nov 01 15:32:27 MSK 2012]; root of context hierarchy

15:32:27,477 105  [main] ERROR springtests.JUnitRunner  - Can't load context

    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:302)

...

UPDATE

XML文件与类文件位于同一文件夹中.从getResource()看到它的事实可以看出.

我不明白你在问什么,但你试过了吗？

new ClassPathXmlApplicationContext("classpath*:test01.xml");

这将在所有类路径中搜索test01.xml.您可以在Spring 资源文档页面中阅读更多相关信息.
