spring笔记-PathMatchingResourcePatternResolver

1. ResourcePatternResolver

ResourcePatternResolver定义了getResources来查找资源

PathMatchingResourcePatternResolver提供了以classpath开头的通配符方式查询,否则会调用ResourceLoader的getResource方法来查找

public interface ResourcePatternResolver extends ResourceLoader {

    Resource[] getResources(String locationPattern) throws IOException;
}

2.加载本地Class

    @Test
    public void singleResourceOnFileSystem() throws IOException {
        Resource[] resources =
                resolver.getResources("org/springframework/core/io/support
/PathMatchingResourcePatternResolverTests.class");
    }

内部还是以ResourceLoader来加载

3. 加载jar包的资源

    @Test
    public void singleResourceInJar() throws IOException {
        Resource[] resources = resolver.getResources("java/lang/URL.class");
        assertEquals(1, resources.length);
        assertProtocolAndFilenames(resources, "jar", "URL.class");
    }

4.以classpath*通配符的方式加载本地class

@Test
    public void classpathStarWithPatternOnFileSystem() throws IOException {
        Resource[] resources = resolver.getResources("classpath*:org/springframework/core/io/sup*/*.class");
    
    }

5.以classpath*通配符的方式加载jar包class

    @Test
    public void classpathStartWithPatternInJar() throws IOException {
        Resource[] resources = resolver.getResources("classpath*:org/apache/commons/logging/*.class");
        
resources = resolver.getResources("classpath*:com/alibaba/dubbo/rpc/filter/**/*.class");
    }
