Class DefaultResourceLoader

java.lang.Object
nl.basjes.parse.useragent.utils.springframework.core.io.DefaultResourceLoader
All Implemented Interfaces:
ResourceLoader
public class DefaultResourceLoader extends Object implements ResourceLoader
Default implementation of the {link ResourceLoader} interface.

Used by {link ResourceEditor}, and serves as base class for {link org.springframework.context.support.AbstractApplicationContext}. Can also be used standalone.

Will return a {link UrlResource} if the location value is a URL, and a {link ClassPathResource} if it is a non-URL path or a "classpath:" pseudo-URL.

  • Constructor Details

    • DefaultResourceLoader

      public DefaultResourceLoader()
      Create a new DefaultResourceLoader.

      ClassLoader access will happen using the thread context class loader at the time of actual resource access (since 5.3). For more control, pass a specific ClassLoader to {link #DefaultResourceLoader(ClassLoader)}. see java.lang.Thread#getContextClassLoader()

    • DefaultResourceLoader

      public DefaultResourceLoader(@Nullable ClassLoader classLoader)
      Create a new DefaultResourceLoader.
      Parameters:
      classLoader - the ClassLoader to load class path resources with, or null for using the thread context class loader at the time of actual resource access

  • Method Details

    • getClassLoader

      @Nullable public ClassLoader getClassLoader()
      Return the ClassLoader to load class path resources with.

      Will get passed to ClassPathResource's constructor for all ClassPathResource objects created by this resource loader. see ClassPathResource

      Specified by:
      getClassLoader in interface ResourceLoader
      Returns:
      the ClassLoader (only null if even the system ClassLoader isn't accessible) see org.springframework.util.ClassUtils#getDefaultClassLoader() see org.springframework.util.ClassUtils#forName(String, ClassLoader)

    • getProtocolResolvers

      public Collection<ProtocolResolver> getProtocolResolvers()
      Return the collection of currently registered protocol resolvers, allowing for introspection as well as modification. see #addProtocolResolver(ProtocolResolver)

    • getResource

      public Resource getResource(String location)
      Description copied from interface: ResourceLoader
      Return a Resource handle for the specified resource location.

      The handle should always be a reusable resource descriptor, allowing for multiple {link Resource#getInputStream()} calls.

      • Must support fully qualified URLs, e.g. "file:C:/test.dat".
      • Must support classpath pseudo-URLs, e.g. "classpath:test.dat".
      • Should support relative file paths, e.g. "WEB-INF/test.dat". (This will be implementation-specific, typically provided by an ApplicationContext implementation.)

      Note that a Resource handle does not imply an existing resource; you need to invoke {link Resource#exists} to check for existence.

      Specified by:
      getResource in interface ResourceLoader
      Parameters:
      location - the resource location
      Returns:
      a corresponding Resource handle (never null) see #CLASSPATH_URL_PREFIX see Resource#exists() see Resource#getInputStream()

    • getResourceByPath

      protected Resource getResourceByPath(String path)
      Return a Resource handle for the resource at the given path.

      The default implementation supports class path locations. This should be appropriate for standalone implementations but can be overridden, e.g. for implementations targeted at a Servlet container.

      Parameters:
      path - the path to the resource
      Returns:
      the corresponding Resource handle see ClassPathResource see org.springframework.context.support.FileSystemXmlApplicationContext#getResourceByPath see org.springframework.web.context.support.XmlWebApplicationContext#getResourceByPath
