Java EE load resource file and spring load XML file

Java EE load XML file

Resource interface, which is the interface used to load files.

Both Filesystemresource and Classpathresource implement the resource interface, which they can use to load XML files.

The specific code is as follows:

1 New Classpathresource ("file. xml"); 2 3 New Filesystemresource ("Drive letter:/project path/src/file. xml");

< Span class= "token p" >< Span class= "token lf" >classpathresource load file, from the source folder (such as SRC), to find the file.

< Span class= "token p" >< Span class= "token lf" > Note: Web project, Files of different source folders will eventually be compiled into the classes directory, so the files under the same homologous folder cannot have the same name, otherwise they will be overwritten.

Filesystemresource load file, is from the drive letter as the starting point, to find the file.

Span id= "wmd-input-section-5" class= "wmd-input-section" >spring load XML file

< Span class= "token lf" >< Span class= "token lf" > Resourceloader in spring is the interface for loading files.

< Span class= "token lf" >< Span id= "wmd-input-section-5" class= "wmd-input-section" >resourcepatternresolver interface inherits the Resourceloader interface.

< Span class= "token lf" > pathmatchingresourcepatternresolver class implemented Resourcepattern Resolver interface.

< Span class= "token lf" > spring loaded The code for the file is as follows:

1Resourcepatternresolver RP =Newpathmatchingresourcepatternresolver ();2 3 //Empty 1, here can be filled in classpath or File,classpath is the project SRC directory as the starting point, file is the drive letter as the starting point. 4 //empty 2, is the path + name of the file. 5Resource Resource = Rp.getresource ("Empty 1: Empty 2");6 7 8 //classpath*9 //empty 1 after adding *, such as classpath*, this means, in the path of the empty 2 under the name is empty 2 name of the file.
