java - 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。在下面的例子中，这是 JUnitRunner.class 文件。 Java 的 getResource()如果路径不是以 /'

开头，文件可以处理这个问题

我想不通，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: true15:32:27,422 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 hierarchy15:32:27,475 103  [main] INFO  org.springframework.beans.factory.xml.XmlBeanDefinitionReader  - Loading XML bean definitions from class path resource [test01.xml]15:32:27,477 105  [main] ERROR springtests.JUnitRunner  - Can't load contextorg.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [test01.xml]; nested exception is java.io.FileNotFoundException: class path resource [test01.xml] cannot be opened because it does not exist    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:341)    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:302)...

更新

XML 文件与类文件位于同一文件夹中。从getResource()看到就可以看出。

我不太明白你在问什么，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 resources 中阅读更多相关信息文档页面。
