类 ClassPathResource

构造器详细资料

• ClassPathResource

  public ClassPathResource​(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

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

• ClassPathResource

  public ClassPathResource​(String path,
                           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​(String path,
                           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​(String path,
                              ClassLoader classLoader,
                              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
