Package org.springframework.boot.io

Class ApplicationResourceLoader

java.lang.Object

org.springframework.core.io.DefaultResourceLoader

org.springframework.boot.io.ApplicationResourceLoader

All Implemented Interfaces:

ResourceLoader

public class ApplicationResourceLoader
extends DefaultResourceLoader

Class can be used to obtain ResourceLoaders supporting additional ProtocolResolvers registered in spring.factories.

When not delegating to an existing resource loader, plain paths without a qualifier will resolve to file system resources. This is different from DefaultResourceLoader, which resolves unqualified paths to classpath resources.

Since:

3.3.0

Create a new ApplicationResourceLoader.

ApplicationResourceLoader

@Deprecated(since="3.4.0",
            forRemoval=true)
public ApplicationResourceLoader(ClassLoader classLoader)

Deprecated, for removal: This API element is subject to removal in a future version.

since 3.4.0 for removal in 3.6.0 in favor of get(ClassLoader)

Create a new ApplicationResourceLoader.

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

getResourceByPath

protected Resource getResourceByPath(String path)

Overrides:

getResourceByPath in class DefaultResourceLoader

get

public static ResourceLoader get()

Return a ResourceLoader supporting additional ProtocolResolvers registered in spring.factories. The factories file will be resolved using the default class loader at the time this call is made. Resources will be resolved using the default class loader at the time they are resolved.

Returns:

a ResourceLoader instance

Since:

3.4.0

get

public static ResourceLoader get(ClassLoader classLoader)

Return a ResourceLoader supporting additional ProtocolResolvers registered in spring.factories. The factories files and resources will be resolved using the specified class loader.

Parameters:

classLoader - the class loader to use or null to use the default class loader

Returns:

a ResourceLoader instance

Since:

3.4.0

get

public static ResourceLoader get(ClassLoader classLoader,
 SpringFactoriesLoader springFactoriesLoader)

Return a ResourceLoader supporting additional ProtocolResolvers registered in spring.factories.

Parameters:

classLoader - the class loader to use or null to use the default class loader

springFactoriesLoader - the SpringFactoriesLoader used to load ProtocolResolvers

Returns:

a ResourceLoader instance

Since:

3.4.0

get

public static ResourceLoader get(ResourceLoader resourceLoader)

Return a ResourceLoader delegating to the given resource loader and supporting additional ProtocolResolvers registered in spring.factories. The factories file will be resolved using the default class loader at the time this call is made.

Parameters:

resourceLoader - the delegate resource loader

Returns:

a ResourceLoader instance

Since:

3.4.0

get

public static ResourceLoader get(ResourceLoader resourceLoader,
 boolean preferFileResolution)

Return a ResourceLoader delegating to the given resource loader and supporting additional ProtocolResolvers registered in spring.factories. The factories file will be resolved using the default class loader at the time this call is made.

Parameters:

resourceLoader - the delegate resource loader

preferFileResolution - if file based resolution is preferred over ServletContextResource or ClassPathResource when no resource prefix is provided.

Returns:

a ResourceLoader instance

Since:

3.4.1

get

public static ResourceLoader get(ResourceLoader resourceLoader,
 SpringFactoriesLoader springFactoriesLoader)

Return a ResourceLoader delegating to the given resource loader and supporting additional ProtocolResolvers registered in spring.factories.

Parameters:

resourceLoader - the delegate resource loader

springFactoriesLoader - the SpringFactoriesLoader used to load ProtocolResolvers

Returns:

a ResourceLoader instance

Since:

3.4.0
