如何在Spring 3.1中使用通配符加载xml资源文件 [英] How to load xml resource file using wild card in Spring 3.1

问题描述

我想加载xml文件，其中包含Spring Maven项目中几个模块的一些错误定义。我想加载然后将文件传递给JAXB unmasheller。

I want to load xml files which contains some error definitions of several modules in a Spring Maven project. I want to load and then pass the file to a JAXB unmasheller.

这是我到目前为止所做的事情

This is what I have done so far

String path = "classpath*:/**/definitions/error-definition.xml";
ClassPathResource resource = new ClassPathResource(path);
unmarshaller.unmarshall(resource);

我的资源文件位于以下位置

My resource files are located as follows

src / main / resource / module1 / definitions / error-definition.xml

src/main/resource/module2/definitions/error-definition.xml

这给了我以下错误

java.io.FileNotFoundException: class path resource [classpath*:/**/definitions/error-definition.xml] cannot be resolved to URL because it does not exist

但当我更改路径时如下

 String path = "/module1/definitions/error-definition.xml";

工作原理

以下是其他我尝试没有运气的外卡

Following are the other wild card which I tried with no luck

String paths = "classpath:/**/definitions/error-definition.xml";
String paths = "classpath*:error-definition.xml";
String paths = "classpath*:*.xml";

我想要做的是使用通配符从<$下的任何文件夹中获取xml文件c $ c> src / main / resource

What I want to do is to use wild card to get the xml files from any folder under src/main/resource

我之前提到过几个SO答案，但仍然无法弄清楚我做错了什么。 / p>

I referred several previous SO answers but still couldn't figure out what Im doing wrong.

推荐答案

要加载资源，请将 ResourceLoader 注入您的班级。您可以通过实现 ResourceLoaderAware 或仅使用 @注释 ResourceLoader 类型的字段来执行此操作自动装配Autowired 。

To load resource inject the ResourceLoader into your class. You can do this by either implementing ResourceLoaderAware or simply annotate a field of type ResourceLoader with @Autowired.

public class YourClass {

    @Autowired
    private ResourceLoader rl;

}

现在您拥有 ResourceLoader 您可以使用 ResourcePatternUtils 来实际加载资源。

Now that you have the ResourceLoader you can use the ResourcePatternUtils to actually load the resources.

public Resource[] loadResources() {
    return ResourcePatternUtils.getResourcePatternResolver(rl).getResources("classpath:/directory/**/*-context.xml);

}
