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

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

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

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).

返回:

the path of this resource

getClassLoader

public final java.lang.ClassLoader getClassLoader()

Return the ClassLoader that this resource will be obtained from.

返回:

the ClassLoader

getInputStream

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

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

返回:

the inputstram of the resource

抛出:

java.io.IOException

getURL

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

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

返回:

the URL of the resource

抛出:

java.io.IOException

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.

返回:

the file reference of the resource

抛出:

java.io.IOException

getFile2Check

protected java.io.File getFile2Check()
                              throws java.io.IOException

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

指定者:

getFile2Check 在类中 AbstractResource

返回:

the file reference

抛出:

java.io.IOException - if the resource cannot be resolved as absolute file path, i.e. if the resource is not available in a file system

getResourceName

public java.lang.String getResourceName()

returns the name of the file that this class path resource refers to.

返回:

the name of resource

getResourceLocation

public java.lang.String getResourceLocation()

equals

public boolean equals(java.lang.Object obj)

compares the underlying class path locations.

覆盖:

equals 在类中 java.lang.Object

返回:

equals or not, true is equal

hashCode

public int hashCode()

覆盖:

hashCode 在类中 java.lang.Object

getOutputStream

public java.io.OutputStream getOutputStream()
                                     throws java.io.IOException
