ClassPathResource

public ClassPathResource(java.lang.String path)

Create a new ClassPathResource for ClassLoader usage. A leading slash will be removed, as the ClassLoader resource access methods will not accept it.

The thread context class loader will be used for loading the resource.

参数:

path - the absolute path within the class path

另请参阅:

ClassLoader.getResourceAsStream(String), ClassUtils.getDefaultClassLoader()

ClassPathResource

public ClassPathResource(java.lang.String path,
                         java.lang.ClassLoader classLoader)

Create a new ClassPathResource for ClassLoader usage. A leading slash will be removed, as the ClassLoader resource access methods will not accept it.

参数:

path - the absolute path within the classpath

classLoader - the class loader to load the resource with, or null for the thread context class loader

另请参阅:

ClassLoader.getResourceAsStream(String)

ClassPathResource

public ClassPathResource(java.lang.String path,
                         java.lang.Class clazz)

Create a new ClassPathResource for Class usage. The path can be relative to the given class, or absolute within the classpath via a leading slash.

参数:

path - relative or absolute path within the class path

clazz - the class to load resources with

另请参阅:

Class.getResourceAsStream(java.lang.String)

ClassPathResource

protected ClassPathResource(java.lang.String path,
                            java.lang.ClassLoader classLoader,
                            java.lang.Class clazz)

Create a new ClassPathResource with optional ClassLoader and Class. Only for internal usage.

参数:

path - relative or absolute path within the classpath

classLoader - the class loader to load the resource with, if any

clazz - the class to load resources with, if any

方法详细资料

getPath

public final java.lang.String getPath()

Return the path for this resource (as resource path within the class path).

getClassLoader

public final java.lang.ClassLoader getClassLoader()

Return the ClassLoader that this resource will be obtained from.

getInputStream

public java.io.InputStream getInputStream()
                                   throws java.io.IOException

This implementation opens an InputStream for the given class path resource.

抛出:

java.io.IOException

另请参阅:

ClassLoader.getResourceAsStream(String), Class.getResourceAsStream(String)

getURL

public java.net.URL getURL()
                    throws java.io.IOException

This implementation returns a URL for the underlying class path resource.

指定者:

getURL 在接口中 org.frameworkset.util.io.Resource

覆盖:

getURL 在类中 AbstractResource

抛出:

java.io.IOException

另请参阅:

ClassLoader.getResource(String), Class.getResource(String)

getFile

public java.io.File getFile()
                     throws java.io.IOException

This implementation returns a File reference for the underlying class path resource, provided that it refers to a file in the file system.

指定者:

getFile 在接口中 org.frameworkset.util.io.Resource

覆盖:

getFile 在类中 AbstractResource

抛出:

java.io.IOException

另请参阅:

This implementation determines the underlying File (or jar file, in case of a resource in a jar/zip).

覆盖:

getFileForLastModifiedCheck 在类中 AbstractResource

返回:

the File to use for timestamp checking (never null)

抛出:
